*880 OPINION AND ORDER
The Amended Original Complaint (instrument # 12) in above referenced cause alleges (1) breach of a Master Services Contract (“MSC”), and of Work Releases pursuant to it, to provide barges, tug boats, and other equipment to separate crude oil from water in Plaintiff BP Exploration & Production Ine.’s (“BP’s”) cleanup response to the Deepwater Horizon oil spill, (2) money had and received, and (3) unjust enrichment and seeks to recover approximately $12,000,000 in overpay-ments made to Defendants Cashman Equipment Corporation (“Cashman”), LAD Services of Louisiana, LLC (“LAD”), and Cashman Equipment Corp. & LAD Services, a Joint Venture (the “Joint Venture”).1 Pending before the Court is Defendant Cashman’s motion for summary judgment (# 86).
Specifically BP complains that the Joint Venture invoiced and received overpay-ments for work authorized in the July Work Releases (numbers 14-21, signed by Cashman through its General Counsel, Andrew Saunders),2 involving the chartering of the Joint Venture’s skimming barges. Under the MSC,3 BP retained the right to pay invoices when they were received and to dispute or “contest the correctness of the amount and seek reimbursement” later. Art. 904 (“[Pjayment of any amount, including any disputed amount, by Company will not waive Company’s right subsequently to contest the correctness of the amount and seek reimbursement from Contractor.”). The MSC further gave BP the right to audit Defendants, which were required to maintain “complete and correct Documentation” related to all work done for BP. Arts. 23.01, 23.03. After paying Defendants more that $68 million based on Defendants’ invoices, BP notified Defendants on November 1, 2011 that it would conduct an audit of the charges. That audit, according to BP, revealed millions of dollars of overcharges.
Standard of Review
Summary judgment under Federal Rule of Civil Procedure 56(c) is appropriate when, viewing the evidence in the light most favorable to the nonmovant, the court determines that “the pleadings, depositions, answers to interrogatories and admissions on file, together with the affidavits, show that there is no genuine issue as to any material fact and that the moving party is entitled to judgment as a matter of law.” A dispute of material fact is “genuine” if the evidence would allow a reasonable jury to find in favor of the nonmovant. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986).
Where the nonmovant bears the burden of proof at trial, the movant must offer *881evidence that undermines the nonmovant’s claim or point out the absence of evidence supporting essential elements of the non-movant’s claim; “the movant may, but does not have to, negate the elements of the nonmovant’s case to prevail on summary judgment.” Celotex Corp. v. Catrett, 477 U.S. 317, 323, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986); Lujan v. National Wildlife Federation, 497 U.S. 871, 885, 110 S.Ct. 3177, 111 L.Ed.2d 695 (1990); Edwards v. Your Credit, Inc., 148 F.3d 427, 431 (5th Cir.1998).
If the movant meets its burden and points out an absence of evidence to prove an essential element of the nonmovant’s case on which the nonmovant bears the burden of proof at trial, the nonmovant must then present competent summary judgment evidence to support the essential elements of its claim and to demonstrate that there is a genuine issüe of material fact for trial. National Ass’n of Gov’t Employees v. City Pub. Serv. Board, 40 F.3d 698, 712 (5th Cir.1994). “[A] complete failure of proof concerning an essential element of the nonmoving party’s case renders all other facts immaterial.” Celotex, 477 U.S. at 323, 106 S.Ct. 2548. The nonmovant may not rely merely on allegations, denials in a pleading or unsubstantiated assertions that a fact issue exists, but must set forth specific facts showing the existence of a genuine issue of material fact concerning every element of its cause(s) of action. Morris v. Covan World Wide Moving, Inc., 144 F.3d 377, 380 (5th Cir.1998).
Conclusory allegations unsupported by evidence will not preclude summary judgment. National Ass’n of Gov’t Employees v. City Pub. Serv. Board, 40 F.3d at 713; Eason v. Thaler, 73 F.3d 1322, 1325 (5th Cir.1996). “ ‘[T]he mere existence of some alleged factual dispute between the parties will not defeat an otherwise properly supported motion for summary judgment....’” State Farm Life Ins. Co. v. Gutterman, 896 F.2d 116, 118 (5th Cir.1990), quoting Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 247-48, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). “Nor is the ‘mere scintilla of evidence’ sufficient; ‘there must be evidence on which the jury could reasonably find for the plaintiff.’ ” Id., quoting Liberty Lobby, 477 U.S. at 252, 106 S.Ct. 2505. The Fifth Circuit requires the nonmovant to submit “ ‘significant probative evidence.’ ” Id., quoting In re Municipal Bond Reporting Antitrust Litig., 672 F.2d 436, 440 (5th Cir.1982), and citing Fischbach & Moore, Inc. v. Cajun Electric Power Co-op., 799 F.2d 194, 197 (5th Cir.1986). “If the evidence is merely color-able, or is not significantly probative, summary judgment may be granted.” Thomas v. Barton Lodge II, Ltd., 174 F.3d 636, 644 (5th Cir.1999), citing Celotex, 477 U.S. at 322, 106 S.Ct. 2548, and Liberty Lobby, 477 U.S. at 249-50, 106 S.Ct. 2505.
Allegations in a plaintiffs complaint are not evidence. Wallace v. Texas Tech Univ., 80 F.3d 1042, 1047 (5th Cir.1996) (“[Pjleadings are not summary judgment evidence.”); Johnston v. City of Houston, Tex., 14 F.3d 1056, 1060 (5th Cir.1995) (for the party opposing the motion for summary judgment, “only evidence — not argument, not facts in the complaint — will satisfy’ the burden.”), citing Solo Serve Corp. v. Westowne Assoc., 929 F.2d 160, 164 (5th Cir.1991). The nonmovant must “go beyond the pleadings and by [his] own affidavits, or.by depositions, answers to interrogatories and admissions on file, designate specific facts showing that there is. a. genuine issue of material fact for trial.” Giles v. General Elec. Co., 245 F.3d 474, 493 (5th Cir.2001), citing Celotex, 477 U.S. at 324, 106 S.Ct. 2548.
The court must consider all evidence and draw all inferences from the factual record in the light most favorable to. the *882nonmovant. Matsushita Elec. Indus. Co. v. Zenith Radio, 475 U.S. 574, 587, 106 S.Ct. 1348, 89 L.Ed.2d 538 (1986); National Ass’n of Gov’t Employees v. City Pub. Serv. Board, 40 F.3d at 712-13. The Court may not make credibility determinations. Deville v. Marcantel, 567 F.3d 156, 164 (5th Cir.2009), citing Turner v. Baylor Richardson Medical Center, 476 F.3d 337, 343 (5th Cir.2007).
Relevant Law
MSC and Work Releases
The MSC is a “blanket contract” that constitutes the first stage of the contractual relationship, while the work orders for performance of specific work issued subsequently constitute the second stage. “When the parties agreement consists of two parts — the blanket agreement and a subsequent work order — the two must be interpreted together when determining whether maritime law governs the contractual dispute.” Dominion Exploration & Production, Inc. v. Delmar Systems, Inc., No. Civ.A. 07-9492, 2012 WL 6020121, at *5 n. 6 (E.D.La.2012), citing Grand Isle Shipyard v. Seacor Marine, LLC, 589 F.3d 778, 787 n. 6 (5th Cir.2009), and Davis & Sons, Inc. v. Gulf Oil Corp., 919 F.2d 313, 315-16 (5th Cir.1990) (“If, as in this case, the contract consists of two parts, a blanket contract followed by later work orders, the two must be interpreted together in evaluating whether maritime or land law is applicable to the interpretation and enforceability of the contract’s provisions. The blanket contract is not of itself complete and calls for no specific work. The actual contract between the parties therefore consists of the blanket agreement as modified by the later work order.”).
General Maritime Law
The MSC at issue here provides that “to the maximum extent permissible” any dispute related to the contract “shall be governed by the general maritime laws of the United States”; where maritime law is held inapplicable-by a court of competent jurisdiction, ... “the laws of the State of Texas shall apply....” # 86-1, Ex. A, arts. 24.01 and 24.03.
If an action falls within admiralty jurisdiction, federal courts apply substantive admiralty law to claims that sound in admiralty, regardless of whether jurisdiction is also based upon diversity, as is the case here. See, e.g., Pope & Talbot, Inc. v. Hawn, 346 U.S. 406, 410-11, 74 S.Ct. 202, 98 L.Ed. 143 (1953) (“While states may sometimes supplement federal maritime policies, a state may not deprive a person of any substantial admiralty rights as defined on controlling acts of Congress or by interpretive decisions of this Court.”); Thibodaux v. Atlantic Richfield Co., 580 F.2d 841, 846 (5th Cir.1978) (discussing Pope at pp. 409-10, 74 S.Ct. 202: “The Constitution provides that Judicial Power shall extend ‘to all cases of admiralty and maritime jurisdiction.’ This constitutional grant of jurisdiction has been construed to mean that general maritime law is to be placed under national control in ‘its substantive as well as its procedural features .... ’ ... It is settled ... that state law must yield to the needs of a uniform federal maritime system when inroads by the state cause disharmony.”). A constant, fundamental premise of Supreme Court opinions “is that the uniformity of admiralty law must be preserved and that state law may be applied only where it works no ‘material prejudice to the essential features of the general maritime law.’ That uniformity is not to be sacrificed to accommodate state law is a fundamental premise of admiralty jurisdiction.” Green v. Vermilion Corp., 144 F.3d 332, 341 (5th Cir.1998), citing John Baizley Iron Works v. Span, 281 U.S. 222, 50 S.Ct. 306, 74 L.Ed. 819 (1930), and Grant Gilmore & Charles L. Black, Jr., The Law of Admiralty § 6-58 to 6-61 (2d ed.1975); Curtis Calíais *883Welding, Inc. v. Stolt Comex Seaway Holdings, 129 Fed.Appx. 45, 52-53 (5th Cir.2005).
In East River S.S. Corp. v. Trans-america Delaval, Inc., 476 U.S. 858, 864-65, 106 S.Ct. 2295, 90 L.Ed.2d 865 (1986) (citations omitted), the United States Supreme Court explained,
With admiralty jurisdiction comes the application of substantive admiralty law. Absent a relevant statute, the general maritime law, as developed by the judiciary, applies. Drawn from state and federal sources, the general maritime law is an amalgam of traditional common-law rules, modifications of those rules, and newly created rules.
The Fifth Circuit opined in McBride v. Estis Well Serv., LLC, 731 F.3d 505, 507-08 (5th Cir.2013), on rehearing en banc, 768 F.3d 382, 405 (5th Cir.2014), cert. denied — U.S.-, 135 S.Ct. 2310, 191 L.Ed.2d 978 (2015),
There are two primary sources of federal maritime law: common law developed by federal courts exercising the maritime authority conferred on them by the Admiralty Clause of the Constitution (“general maritime law”), and statutory law enacted by Congress exercising its authority under the Admiralty Clause and the Commerce Clause (“statutory maritime law”).
Although Congress is authorized to pass laws regarding maritime activities, a significant part of substantive maritime law has come from common law principles of the Supreme Court and “States can no more override such judicial rules validly fashioned than they can override Acts of Congress.” Wilburn Boat Co. v. Fireman’s Fund Ins. Co., 348 U.S. 310, 314, 75 S.Ct. 368, 99 L.Ed. 337 (1955). There is no dispute among the parties that the contract at issue here is a maritime contract and the Court agrees. Whether a contract is a maritime contract is determined by its nature and character, not by its place of execution or performance. N. Pac. S.S. Co. v. Hall Bros. Marine Ry. & Shipbuilding Co., 249 U.S. 119, 125-26, 39 S.Ct. 221, 63 L.Ed. 510 (1919). “[T]he true criterion is whether the contract has “reference to maritime service of maritime transactions.” ” Id. “A contract relating to a ship in its use as such, or to commerce or navigation on navigable waters, or to transportation by sea or to maritime employment is subject to maritime law.” Davis & Sons, Inc. v. Gulf Oil Corp., 919 F.2d 313, 316 (5th Cir.1991), quoting E. Jhirad, A. Sann, B. Chase & M. Chynsky, Benedict on Admiralty § 182 (1988). “When interpreting maritime contracts, federal admiralty law rather than state law applies.” International Marine, LLC v. Delta Towing, LLC, 704 F.3d 350, 354 (5th Cir.2013), citing Har-Win, Inc. v. Consol. Grain & Barge Co., 794 F.2d 985, 987 (5th Cir.1986) (collecting citations). In addition to the choice of law provision, the MSC • and Work Releases deal with the chartering of vessels and equipment from Defendants, their use on those vessels in the Gulf of Mexico to clean up the oil spill, and the billing for these services. See, e.g., In re: Oil Spill by Oil Rig “Deepwater Horizon” in the Gulf of Mexico, on April 20, 2011, No. MDL 2179, 2011 WL 4575696 (E.D.La. Sept. 30, 2011) (holding that general maritime law preempts state law). “It is well established that a charter agreement is a maritime contract.” Morewood v. Enequist, 64 U.S. 491, 23 How. 491, 16 L.Ed. 516 (1860).
When interpreting a maritime contract, the court applies the general ordinary rules of contract construction and interpretation.4 Marine Overseas Servs., Inc. v. Crossocean Shipping Co., 791 F.2d *8841227, 1234 (5th Cir.1986); Stoot v. Fluor, 851 F.2d at 1517; Theriot v. Bay Drilling Corp., 783 F.2d 527, 538 (5th Cir.1986) (“the construction of a maritime contract is governed by maritime law”).
“When interpreting a maritime contract, general principles of contract law apply from federal admiralty law, rather than from state law.” International Marine, L.L.C. v. FDT, L.L.C., 619 Fed.Appx. 342, 348, No. 14-31192, 2015 WL 4720257, at *5 (5th Cir. Aug. 10, 2015), citing Har-Win, Inc. v. Consol. Grain & Barge Co., 794 F.2d 985, 986-87 (5th Cir.1986). “ ‘Applying federal law in the contract context includes looking to ‘principles of general contract law’ that can be found in treatises or restatements of the law.’ ” Id., quoting Univ. of Tex. Sys. v. United States, 759 F.3d 437, 443 (5th Cir.2014) (in turn quoting Franconia Assocs. v. United States, 536 U.S. 129, 141-42, 122 S.Ct. 1993, 153 L.Ed.2d 132 (2002)), cert. denied, — U.S. -, 135 S.Ct. 1894, 191 L.Ed.2d 763 (2015). In admiralty actions under federal common law the choice of law is determined in accordance with the Restatement (Second) of Conflicts of Laws. In re ATP Oil & Gas Corp., 531 B.R. 694 (Bkrtey. S.D.Tex.2015), citing Chan v. Soc’y Expeditions, Inc., 123 F.3d 1287 (9th Cir.1997).
Interpretation of the terms of a contract is a matter of law. Offshore Marine Contractors, Inc. v. Palm Energy Offshore, LLC, 779 F.3d 345, 348 (5th Cir.2015). The terms of a maritime eon-tract are given their plain meaning unless the provision is ambiguous. Weathersby v. Connoco Oil Co., 752 F.2d 953, 956 (5 th Cir.1984). If a contract’s “language as a whole is clear, explicit, and leads to no absurd consequences, and as such it can be given only one reasonable interpretation,” it is not ambiguous. Chembulk Trading LLCv. Chemex Ltd., 393 F.3d 550, 555 n. 6 (5th Cir.2004). Under federal maritime law only if the contract provision is ambiguous may a court look beyond the written language of the contract to determine the intent of the parties. International Marine, 619 Fed-Appx. at 348, 2015 WL 4720257, at *5, citing Corbitt v. Diamond M. Drilling Co., 654 F.2d 329, 332-33 (5th Cir. Unit A1981).
General maritime law incorporates the Uniform Commercial Code. Clem Perrin Marine Towing, Inc. v. Panama Canal Co., 730 F.2d 186, 189 (5th Cir.) (the “U.C.C. has been regarded as a source for both admiralty and federal common law”), cert. denied, 469 U.S. 1037, 105 S.Ct. 515, 83 L.Ed.2d 405 (1984). The same is true of the Restatements of Contracts. See, e.g., International Marine, LLC v. Delta Towing, LLC, 704 F.3d at 354; One Beacon Ins. Co. v. Crowley Marine Services, Inc., 648 F.3d 258, 265 (5th Cir.2011); Sea Byte, Inc. v. Hudson Marine Management Services, Inc., 565 F.3d 1293, 1302 (11th Cir.2009); Doucette v. Vincent, 194 F.2d 834, 838-39 (1st Cir.1952).
“Under federal maritime choice of law rules, contractual choice of *885law provisions are generally recognized as valid and enforceable.”; “ ‘where the parties have included a choice of law clause, that state’s law will govern unless the state has no substantial relationship to the parties or the transaction .or the state’s law conflicts with the fundamental purposes of maritime law.’ ” Great Lakes Reinsurance (UK) PLC v. Durham Auctions, Inc., 585 F.3d 236, 242 (5th Cir.2009) (quoting Stoot v. Fluor, 851 F.2d 1514, 1517 (5th Cir.1988)). Here the choice of law clause selects general maritime law, with Texas, law to be applied for any matters not covered by general maritime law.5
Liability of a Louisiana Joint Venture Under Louisiana Law
Cashman argues that Louisiana substantive and procedural law applies here, while BP contends that federal maritime or, where there is none, Texas substantive and procedural law applies.
Courts in Louisiana look to the laws of partnership when they determine whether the parties have created a joint venture. Transit Management of Southeast Louisiana, Inc. v. Group Ins. Admin., Inc., 226 F.3d 376, 383 (5th Cir.2000) (“Under Louisiana jurisprudence the fundamental elements of a joint venture are generally the same as those of partnership, and, accordingly, joint ventures are governed by the law of partnership.”); Brees v. Houser, No. Civ.A. 13-4760, 2014 WL 3587333, at *7 (E.D.La. July 21, 2014). A partnership is defined “ ‘as a ‘juridical person, distinct from its partners, created by a contract between two or more persons to combine their efforts or resources in determined proportions and to collaborate at mutual risk for their common profit or commercial benefit.’ ’ ” Brees, 2014 WL *8863587333, at *7, quoting Lang v. Sproull, 36 So.3d 407, 412 (La.App. 2 Cir.2010), quoting La. Civ.Code Ann. art. 2801.6 A written agreement is not required to prove the existence of a joint venture, but a plaintiff has the burden of establishing that ‘“(1) the alleged partners mutually agreed to form a partnership and to participate in the profits which would accrue from the business in determined proportions; (2) they agreed to share in the losses as well as the profits of the partnership; and (3) the property or stock of the enterprise formed a community of goods in which each party has a proprietary interest,’ ” Id. at *8, quoting Porter v. Porter, 821 So.2d 663, 671 (La.App. 2 Cir.2002).
“A partnership has the procedural capacity to be sued in its partnership name. The partners of an existing partnership may not be sued on a partnership obligation unless the partnership is joined as a defendant.” Louisiana Code of Civil Procedure Art. 737; Casten v. Cordell, 649 So.2d 123, 126 (La.App. 2 Cir.1995) (the partnership is an indispensable party), citing Louisiana Code of Civil Procedure art. 737. The partnership is the primary obligor. La. Civ.Code Art. 2817. Travelers Ins. Co. v. St. Jude Hospital of Kenner, Louisiana, 37 F.3d 193, 195-96 (5th Cir.1994).
Louisiana has a unique method of limiting a general partner’s liability for debt to third parties. Under Louisiana Civil Code Annotated article 2817, “A partner is [secondarily] bound for his virile share of the debts of the partnership.” Brees, 2014 WL 3587333, at *7. “Virile share” in article 2817 means “per head liability among partners of a general partnership”; each joint obligor owes an equal share of the debt, which is calculated by dividing the amount owed by the number of obligors. Hibernia Nat. Bank v. Carner, 997 F.2d 94, 99 and nn. 4 and 5 (5th Cir.1993), as clarified on denial of rehearing (Sept. 15, 1993). As explained in 7 Glenn G. Morris and Wendell H. Holmes, Louisiana Civil Law Treatise § 2.10 (“Meaning of ‘virile share’ ”) (database updated June 2015),
Although the issue is not free of doubt, the term “virile share” in article 2817 of the Civil Code appears to mean “a proportionate share, based on the number of liable partners in the partnership.” Under this view, each liable partner owes an equal share of the partnership debt to the third party creditor, regardless of the size of the partner’s capital contribution, and regardless of the share of profits and losses that the partnership agreement says he is to hold.7
*887Id., citing Hibernia Nat. Bank (one of eight partners owed partnership creditor one-eighth, i.e., 12.5%, of partnership’s debt even though he held only a 5% interest in the partnership). Furthermore, id. at § 2.11 (“Effects of virile share rule”),
Once [a partner] pays his own proportionate part of the partnership’s debts, his obligation is satisfied. Even if the partnership is incapable of paying the remaining portion of its own debts, and even if the other partners are incapable of paying their own respective shares of those debts, Louisiana law limits any given partner’s liability strictly to the amount necessary to pay his own proportionate share of the partnership debts. Any remaining loss must be borne by the partnership’s creditors, and not by the other partners' — even if financially comfortable — who have already paid their own proportionate part of the partnership’s debts.
Because under Louisiana law partners are only secondarily liable for the debts of the partnership, article 2817 permits them to plead the affirmative defense of “discussion” of the partnership’s assets. “Discussion is the right of a secondary obligor to compel the creditor to enforce the obligation against the property of the primary obligor ... before enforcing it against the property of the secondary obligor.” La. Civ. Proc. art. 5151. See, e.g., Nichols v. Pipes, 353 So.2d 1086, 1087 (La.App.1977) (Creditor can join the surety with the principal debtor and obtain judgment against both, but only requires that any judgment in the suit be executed first against the principal debtor) (citing Louisiana Civil Code art. 2051 and Louisiana Code of Civil Procedure arts. 5151-5156), writ denied, 355 So.2d 264 (La.1978).
On the other hand, while the partnership must be sued first, either by itself or along with partners, the partners may be sued individually subsequently, even though it may be more economical and expedient to have joined the partners in the first suit, as long as the partnership was found liable in the first suit. See, e.g., F.D.I.C. v. Mmahat, 960 F.2d 1325, 1329-30 (5th Cir.1992) (finding subsequent suit against a partner individually and as a secondary obligor was not barred by res judicata because it was a suit to collect on an earlier judgment against the partnership as primary obligor), cert. denied sub nom. Duffy v. F.D.I.C., 506 U.S. 1078, 113 S.Ct. 1044, 122 L.Ed.2d 353 (1993). As the Fifth Circuit opined, id, at 1328-29,
Neither federal nor Louisiana law requires the joinder of all partners in an action against a partnership. See 7 Charles A. Wright, Arthur Miller & Mary Kay Kane, Federal Practice and Procedure § 1623 (2d ed.1986) (joinder unnecessary for partners who are jointly and severally liable); Koppers Co. v. Mackie Roofing & Sheet Metal Works, 544 So.2d 25, 26 (La.App.1989) (The purpose of La.Code Civ. P. art. 737 is not to “make it mandatory that the partners be *888named as defendants every time a partnership it sued”; rather its purpose is to require a partnership creditor first to “exhaust his rights against the partnership before he proceeds against the individual partners.”).... See generally Restatement (Second) of Judgments § 60 (1982) (a successful lawsuit against one partner does not bar subsequent lawsuits against other partners individually on the same debt); 7 Federal Practice and Procedure § 613 at 196 n. 32 (noting that Official Comment to the Uniform Partnership Act § 15 recognizes that under some state partnership laws, “the partnership may be sued in the partnership name and thereafter the partners separately until satisfaction is had”). Under the Louisiana law of partnerships, each partner is secondarily liable for his virile share of the partnership debts. See La. Civ.Code Art. 2817.
Where, as a secondary obligor, a member of a partnership or joint venture pleads discussion, the secondary obligor is required under Louisiana Civil Procedure Code art. 5155 to
(1) Point out by a description sufficient to identify it, property in the state belonging to the primary obligor, or otherwise subject to discussion, which is not in litigation, is not exempt from seizure, is free of mortgages and privileges, and is worth more than the total amount of the judgment or. mortgage; and
(2) Deposit into the registry .of the court, for the use of the creditor, an amount sufficient to defray the costs of executing the judgment or enforce the mortgage against the property discussed.
Hibernia Nat. Bank, 997 F.2d at 101-92. Furthermore, where the party pleading discussion did not comply with these requirements, the Court need not address the plea of discussion on the its merits. Travelers Insurance Co. v. St. Jude Hosp. of Kenner, La., No. Civ.A. 93-0173, 1993 WL 408337, at *3 (E.D.La. Sept. 30, 1993), citing Thompson-Ritchie Grocery Co. v. Cary, 17 La.App. 270, 135 So. 707 (1931).
Cashman’s alleged affirmative defense of discussion (Cashman’s Second Supplemental and Amended Answer, Affirmative Defenses and Counterclaim, attachment to # 73, ¶ 94) asserts the following:
... BP as Plaintiff, must first pursue its legal remedies against Joint Venture as required by Louisiana law, which is the law applicable to claims alleged, or that might be alleged against Cashman as a party to a Louisiana Joint Venture. BP and Joint Venture were the only parties to the contract made the basis of plaintiffs claims in this case. Cashman signed the contract as a representative of Joint Venture and not as an individual party. From the document alleged by Plaintiff to constitute the contract under which Plaintiff has brought its claims it is clear that Joint Venture was the contracting party and any document signed by Cashman, or otherwise sent by. Cash-man to BP, was as a representative of Joint Venture. Cashman specifically denies that it was a party to said contract and Cashman cannot be sued by Plaintiff for contract claims under a contract to which Cashman was not a party. Cashman has no liability for any of the claims alleged by Plaintiff and any alleged claim Plaintiff may bring against Cashman for the debts of the Joint Venture is limited under Louisiana law to a claim for Cashman’s virile share of any alleged Joint Venture debt.

As with Louisiana law, joint ventures under Texas law are treated similarly to the way partnerships are treated under that state’s law. McCabe v. Henpil, Inc., 889 F.Supp. 983, 993 (E.D.Tex.1995), *889citing Brazosport Bank v. Oak Park Townhouses, 889 S.W.2d 676, 683 (Tex. App.-Houston [14th Dist.] 1994, writ denied). See also 1 Tex. Guide Bus. & Com. Litigation, “Definition of partnership-Joint Venture” § 1:2 (updated June 2015) (“The legal distinctions between partnerships and joint ventures have virtually disappeared. Sims v. Western Waste Industries, 918 S.W.2d 682 (Tex.App.-Beaumont 1996, writ denied). As a result, joint ventures are now governed by the same legal principles as partnerships. 626 Joint Venture v. Spinks, 873 S.W.2d 73 (Tex.App.Austin 1993, no writ); McCabe v. Henpil, Inc., 889 F.Supp. 983 (E.D.Tex.1995). The Texas Revised Partnership Act includes joint venture within the definition of partnership. Tex.Rev.Civ. Stat. Ann. 6132b-2.02”).
Under Texas law, in contrast to Louisiana law, however, a joint venturer is “jointly and severally liable for joint venture debts and obligations.” Id., citing Truly v. Austin, 744 S.W.2d 934, 937 (1988), citing Tex.Rev.Civ. Stat. Ann. art. 6132b, § 15 (Vernon 1970). Similarly under traditional general partnership law, each partner is liable jointly and severally for the liabilities of the partnership. Pinebrook Properties, Ltd. v. Brookhaven Lake Property Owners Assoc., 77 S.W.3d 487, 499 (Tex.App.-Texarkana 2002); Crop Production Services, Inc. v. Keeley, 2015 WL 4885345, at *3 (E.D.Tex. Aug. 14, 2015). See Tex. Bus. Orgs.Code § 152.304(a) (“Except as provided by Subsection (b) or Section 152.801(a) [addressing limited liability partnerships], all partners are jointly and severally liable for all obligation of the partnership unless otherwise: (1) agreed to by the claimant; or (2) provided by law.”)
“Under the common law also, ‘parties having a joint and several obligation are bound jointly as one party, and also severally as separate parties as the same time.’ ” 12 Williston on Contracts § 36:1 (4th ed.1999). International Marine, LLC v. Delta Towing LLC, 2013 WL 5890551, at *4 (E.D.La. Nov. 1, 2013).
Texas Common Law Claims
A cause of action for money had and received “ ‘is an equitable doctrine applied to prevent unjust enrichment.’ ”, Berryman’s South Fork, Inc. v. J. Baxter Brinkmann Intern. Corp., 418 S.W.3d 172, 189 (Tex.App.-Dallas 2013, rev. denied), quoting MGA Ins. Co. v. Charles R. Chesnutt, P.C., 358 S.W.3d 808, 813 (Tex.App.Dallas 2012, no pet.). It is “a category of general assumpsit to restore money where equity and good conscience require refund.” Id., citing id. It is not based on wrongdoing but “ ‘looks only to the justice of the case and inquires whether the defendant has received money which rightfully belongs to another.’ ” Id., quoting id. A plaintiff must merely prove that the defendant possesses money which in equity and good conscience belongs to the plaintiff. Id., citing id. Courts use the term, “money had and received,” interchangeably with terms for similar claims, e.g., assumpsit, unjust enrichment, and restitution. H.E.B., L.L.C. v. Ardinger, 369 S.W.3d 496, 507 (Tex.App.-Fort Worth 2012), citing Edwards v. Mid-Continent Office Distributors, L.P., 252 S.W.3d 833, 837 n. 7 (TexApp.-Dallas 2008, rev. denied). See Bank of Saipan v. CNG Fin. Corp., 380 F.3d 836, 840 (5th Cir.2004) (Money had and received “is an equitable doctrine applied to prevent unjust enrichment” under Texas law.).
Texas courts are in conflict about whether there is an independent cause of action for unjust enrichment under Texas law. Amy’s Ice Creams, Inc. v. Amy’s Kitchen, Inc., 60 F.Supp.3d 738, 746 (W.D.Tex.2014). “‘Despite the lack of unanimity among Texas courts, one thing *890remains clear: even in the cases [suggesting unjust enrichment is not an independent cause of action,] the courts have still allowed plaintiffs to recover based on the theory of unjust enrichment so long as a ‘person has obtained a benefit from another by fraud, duress, or the taking of undue advantage.’ ’ ” Id., quoting Newington Ltd. v. Forrester, No. 3:08-CV-0864-G, 2008 WL 4908200, at *4 (N.D.Tex. Nov. 13, 2008), in turn quoting Baisden v. I’m Ready Prods., Inc., No. H-08-0451, 2008 WL 2118170 at’ NO (S.D.Tex. May 16, 2008). Unjust enrichment occurs when a person has wrongfully obtained a benefit or has passively received one which it would be unconscionable to retain. Stewart Title Guar. Co. v. Mims, 405 S.W.3d 319, 339 (Tex.App.-Dallas 2013, no pet.).
Usually if a valid, express contract exists covering the subject matter of the parties’ dispute, a plaintiff cannot recover under a quasi-contract theory such as unjust enrichment or quantum meruit. City of The Colony v. North Texas Mun. Water Dist., 272 S.W.3d 699, 731 (Tex.App.-Fort Worth 2008); Van Duzer v. U.S. Bank Nat. Ass’n, 995 F.Supp.2d 673, 698-99 (S.D.Tex.2014). An exception to this rule arises when overpayment is made under a valid contract. Id. and id., citing Sw. Elec. Power Co. v. Burlington N. R.R. Co., 966 S.W.2d 467, 469-70 (Tex.1998) (“in some circumstances overpayments under a valid contract may give rise to a claim for restitution or unjust enrichment”), in turn citing the following inter alia: Bowers v. Missouri, Kan. & Tex. Ry. Co., 241 S.W. 509, 510-11 (Tex.App.-Texarkana 1922, no writ) (allowing restitution for freight charges paid in excess of rates specified in shipping contract); Gulf Oil Corp. v. Lone Star Producing Co., 322 F.2d 28, 31-33 (5th Cir.1963) (holding that plaintiff could recover money mistakenly paid in excess of contract price); Natural Gas Pipeline Co. v. Harrington, 246 F.2d 915, 921 (5th Cir.1957) (holding that gas company was entitled to restitution of difference between contract rate and price paid under invalid rate order set by regulatory board).
Cashman’s Motion for Summary Judgment (# 86)
Cashman argues first that it cannot be liable for breach of contract, unjust enrichment and/or money had and received because there is no privity of contract between BP and itself. Cashman insists that the Joint Venture, not Cashman, entered into the MSC with BP.
As noted, under Louisiana law, a joint venture member is only liable for its virile share of the joint venture’s debts and only in a secondary capacity. Louisiana Civil Code art. 2817. Cashman claims that BP is suing Cashman directly and not in a secondary capacity, so the claims against it should be dismissed. In Defendants’ Second and Supplemental Amended Answers (copies attached to their motions for leave to file: # 72 (LAD), # 73 (Cashman), and # 74 (“Joint Venture”), respectively), Defendants each asserted an affirmative defense of discussion, i.e., the right under Louisiana Code of Civil Procedure Art. 5151 “of a secondary obligor to compel the creditor to enforce the obligation against the property of the primary obligor,” which in the case of a joint venture is the joint venture itself, “before enforcing it against the property of the secondary obli-gor.” Id., art. 2817. Although BP originally objected to the motion for leave to add the affirmative defense of discussion, it subsequently withdrew that objection while reaffirming its intent to hold Cash-man and LAD liable in all capacities for the damages alleged in BP’s complaint. # 87 at p. 1. Magistrate Judge Stacy granted in part the three Defendants’ motions for leave to file their affirmative defenses of discussion, but denied them as to affirmative defenses or counterclaims based on “set-off’ since the latter were *891precluded by the Deepwater Horizon Settlement Agreement. # 96.
In support of its argument that BP contracted with the Joint Venture only, Cash-man first points to the title of the MSC:
MASTER SERVICE CONTRACT BETWEEN
BP EXPLORATION & PRODUCTION, INC. AND
CASHMAN EQUIPMENT CORP. AND
LAD SERVICES, A JOINT VENTURE.
# 86, Ex. A, p. 2.8
Cashman notes that the same delineation appears in the preamble. # 86, Ex. A,
p. 4.
The preamble of the MSC provides in pertinent part:
THIS CONTRACT is made ... by and between BP EXPLORATION & PRODUCTION INC. (either is hereinafter referred to as “Company”), having an office at 501 WestLake park Boulevard, Houston, Texas 77079, and Cashman Equipment Corp. and LAD Services, a Joint Venture. Cashman Equipment Corp. having its principal office at 161 Granite Avenue, Boston, Massachusetts 02125 and LAD Services having its principal office at 1043 Stephenville Road, Stephenville, Louisiana (Hereinafter referred to as “Contractor”). The entity under this Contract acting as Company shall be determined by the ownership interest in the respective assets which are the subject of the services under this Contract at any given time;, provided, however, in the event that no services are in progress, or other issues of Contract arise which do not pertain to one or the other entity, then both entities of Company shall act as Company. Company and Contractor may hereinafter be referred to collectively as “Parties” or individually as a “Party.” ...
Cashman argues that the MSC individually identifies the Joint Venture as a “Party,” and the MSC collectively identifies BP and Joint Venture as the “Parties.” Id.; preamble and § 2.08 (“ ‘Contractor’ shall refer to the Party designated in the preamble to this Contract.”) and § 2.22 (“ ‘Party’ or ‘Parties’ shall have the meaning set out in the preamble to this Contract.”).
Cashman further emphasizes that the representatives of the Joint Venture partners, Cashman and LAD, simultaneously executed the MSC on Joint Venture’s behalf on May 26, 2010 at 11:03 p.m. Id. at p. 27.
Cashman additionally claims that the Work Releases also reflect that BP’s contract is with the Joint Venture, not with Cashman, in describing the parties as “BP Exploration & Production Inc. and Cash-man Equipment/LAD Services of Louisiana JV.” Ex. B at front page of each Work Release.9 They, too, identify Joint Ven*892ture as “Contractor.” Id. Within each Work Release the identification of “Contractor” distinguishes the two business organizations? Joint Venture Cashman Equipment/LAD Services of Louisiana JV is differentiated from Cashman Corp. Id.
Moreover Cashman points out that the Joint Venture is a Louisiana entity governed by Louisiana law. The MSC provides an election of maritime law or Texas law to govern a contract dispute (# 86-1, Ex. A, arts. 24.01 and 24.03). Cashman contends that since Cashman is not a party to the MSC, it therefore is not bound by the MSC’s choice of law provision. Furthermore article 2817 requires a partnership creditor to exhaust its right against the partnership before proceeding against the individual partners, who are only secondarily liable and only to the extent of their virile or proportionate shares.
Thus Cashman concludes that since it is not a party and is not in privity with BP, BP cannot enforce the contract against Cashman. Crabtree v. Tristar Auto. Group, Inc., 776 F.Supp. 155, 166 (S.D.N.Y.1991), citing 2 Williston on Contracts §§ 273, 347 at 178-80, 793 (3d ed. 1959 & 1983 Supp.). Contracts do not place obligations on non-parties. Puerto Rico Marine Mgmt., Inc. v. Ken Penn Amusement, Inc., 574 F.Supp. 563, 566 (W.D.Pa.1983).
Furthermore as a matter of law where there is an actual contract, argues Cash-man, there can be no quasi-contractual claims, even where the contractual remedy is against a third party. U.S. v. Bollinger Shipyards, Inc., Civ.A. 12-920, 2013 WL 393037 (E.D.La. Jan. 20, 2013) (dismissing unjust enrichment claim based on the existence of a contract, which gave the claimant a contractual remedy against a third party).10 Thus BP’s breach of contract claim precludes its two quasi-contractual claims against any of the Defendants. BP is wrong in insisting it has breach of contract and quasi contract claims (unjust en*893richment and money had and received11) against Cashman directly and not in a secondary capacity. Louisiana joint venture law mandates that Cashman is entitled to dismissal because only the joint venture has primary liability. Cashman insists that it is liable only for its 50% virile share of the Joint Venture’s debts and only in a secondary capacity.
In sum, Cashman is entitled to summary judgment on all BP’s claims. It is not liable for breach of contract because it is a non-party to the MSC and the Work Releases. BP’s contractual claim against the Joint Venture bars BP’s quasi-contractual claims against Cashman for unjust enrichment and money had and received. Last, as a matter of law, a member of a joint venture has no primary liability for the debts of a joint venture and BP has sued Cashman only in a primary capacity, so the claims must be dismissed.
BP’s Response (# 91)
Contending that the motion for summary judgment should be denied, BP responds that Cashman is a party to and a signatory of the MSC for its breach of contract claim, and thus in privity with BP. BP further argues that Cashman is a proper party for BP’s quasi-contract theory because Cashman received more than $12 million in overpayments to which it is not entitled and it is well established that claimants may recover overpayments by asserting quasi-contract claims even where there is a valid contract. Last of all, the motion should be denied because Cashman erroneously states that BP is not pursuing damages against Cashman in all its capacities; BP insists that it is suing Cashman in all its capacities (regardless of whether it is characterized as “direct,” “primary,” “secondary,” or other), including, if necessary, in its capacity as a secondary obligor. Regardless, as a member of the Joint Venture, Cashman is jointly liable for the debts of the Joint Venture even if it is not a party to the contract.12
.BP notes that in determining if privity of contract exists, courts frequently examine a contract’s definitions and its signature block. BP insists that Cashman is expressly and unambiguously defined as a “Contractor” in the contract. In MSC’s second sentence, the MSC clearly and unambiguously identifies Cashman and LAD each as a “Contractor” that assumed rights and obligations under the contract (# 86-1, Ex. A at p. 1, preamble):
Cashman Equipment Corp. having its principal office at 161 Granite Avenue, Boston Massachusetts 02124 and LAD Services having its principal office at 1043 East Stephenville Road, Stephen-ville, Louisiana (hereinafter referred to as “Contractor.”)
There is no mention of the Joint Venture or its address here.13 As sophisticated parties, if the parties wished to identify the Joint Venture as a “Contractor,” they *894would have expressly stated that the “Contractor” is “Cashman Equipment Corp. and LAD Services, a Joint Venture,” and provided its address. The “Contractor” is BP’s direct counterparty under §§ 2.28, 3.01, and 5.01 of the Contract in that the Contractor is obligated to perform services for BP in accordance with the terms of the contract.
When a party signs a contract without designating that it is acting in a representative capacity, as Cashman did here without any qualifying language indicating that it was only signing as an agent of the Joint Venture, it is a party to that contract. Touchton v. Dover Corp./Rotary Lift Div., 319 F.Supp.2d 1290, 1294 (N.D.Ala.2004). The signature block on page 24 of the MSC identifies Cashman as a “Contractor,” and it was signed by Andrew B, Sunders, General Counsel, on behalf of Cashman. No language qualifies Cash-man’s capacity or reflects that it was executed as an agent of the Joint Venture. Similarly the MSC is signed by Lee Drag-na as President of LAD, with the signature block identifying LAD as a “Contractor” under the MSC; again there is no language indicating that Dragna was signing only on the Joint Venture’s behalf. It is well established that the signature of one joint venture member is sufficient to bind the joint venture to the agreement; the two signatures here evidence an intent to bind Cashman and LAD individually. See PCI/RCI v. U.S., 36 Fed.Cl. 761, 769 (1996) (“ ‘The general rule is that each member of a joint venture has the authority to act for and bind the enterprise, absent agreement to the contrary.’ ”), quoting Sadelmi Joint Venture v. Dalton, 5 F.3d 510, 513 (Fed.Cir.1993); Bell v. Morrison, 26 U.S. 351, 370, 1 Pet. 351, 7 L.Ed. 174 (1828) (“By the general law of partnership, the act of each partner, during the continuance of the partnership and within the scope of its objects, binds all the others.”).14
*895BP concludes that the Contract clearly indicates that Cashman is a joint promisor and thus jointly liable under the Contract. See Pitman v. Lightfoot, 937 S.W.2d 496, 528 (Tex.App.-San Antonio 1996, writ denied) (“In the law of contracts, joint and several liability usually arises when two or more promisors in the same contract promise the same or different performances to the same promisee”), citing Restatement (Second) of Contracts §§ 288, 289 (1981), and Corbin On Contracts § 928 (West 1951) (“Each Joint Promisor is Bound For the Whole Performance Promised.”). Texas law is the same: “obligations of multiple parties to a contract are usually ‘joint and several.’ ” Id., citing Marynick v. Bockelmann, 773 S.W.2d 665, 668 (Tex.App.-Dallas 1989), rev’d on other grounds, 788 S.W.2d 569 (Tex.1990), and Guynn v. Corpus Christi Bank & Trust, 620 S.W.2d 188, 190 (Tex.Civ.App.-Corpus Christi 1981, writ ref d n.r.e.).15 Cashman is defined as a “Contractor” obligated to perform services for BP under the Contract and also as a “Party” to the Contract. Cashman executed the Contract in its capacity as Cashman Equipment Corp., without any language indicating that it was signing solely for Joint Venture.
Contrary to Cashman’s claim that the Joint Venture is individually identified as a “Party”, the MSC states at ¶2.22 that “ ‘Party’ or ‘Parties’ shall have the meaning set out in the preamble to the Contract.” The preamble states, “Company and Contractor may hereinafter be referred to collectively as ‘Parties’ or individually as a ‘Party.’ ” Thus the term “Party” is synonymous with “Contractor” when referring to BP’s counterparty. Clearly, as noted, “Contractor” includes Cashman. In sum, Cashman is a party to the MSC and is therefore in privity with BP.
BP asserts that it has shown that Cash-man misconstrues the Contract by relying on language that according the express terms of the contract should not be consulted when interpreting it, and that in doing so, renders multiple provisions *896meaningless and injects ambiguity into what is otherwise an unambiguous contract.
As for the quasi-contract claims based on overpayments being precluded by the existence of a contract, BP argues that the Fifth Circuit has held that this rule does not apply in admiralty where the overpay-ments were caused by the defendant’s inflated invoices under a binding contract. Onaway Transp. Co. v. Offshore Tugs, Inc., 695 F.2d 197, 201-02 (5th Cir.1983) (“[I]t is well established that an excessive payment made in ignorance of the fact it is excessive is recoverable.”) (citing Re statement, Restitution § 20), superseded on other grounds, Missouri Pacific Rail Co. v. Railroad Com’n of Texas, 948 F.2d 179, 182 n. 1 (5th Cir.1991). The rule that money voluntarily paid with full knowledge of all the facts only applies when there is “ ‘an intention on the part of the payor to waive his rights.’ ” Id. at 201, citing West Texas State Bank v. Tri-Service Drilling Co., 339 S.W.2d 249, 253 (Tex.Civ.App.-Eastland 1960); Arkwright-Boston Frs. Mut. Ins. Co. v. Aries Marine Corp., 932 F.2d 442, 447 (5th Cir.1991), citing id., Gulf Oil Corp. v. Lone Star Producing Co., 322 F.2d 28, 31 (5th Cir.1963) (allowing counterclaim for money had and received based on overpayments mistakenly made to counterparty under a contract), and U.S. Fidelity & Guaranty Co. v. Bimco Iron & Metal Corp., 464 S.W.2d 353, 357 (Tex.1971). See also Apache Corp. v. Dynegy Midstream Servs. Ltd. P’ship, 214 S.W.3d 554, 565 (Tex.App.-Houston [14th Dist.] 2006, aff'd in part, rev’d in part on other grounds, 294 S.W.3d 164 (Tex.2009) (noting that there are exception to the general rule that quasi-contract claims are precluded when an express contract governs the subject matter of the lawsuit, such as when the quasi-contract claims are based on overpayments)); Sw. Elec. Power Co. v. Burlington N. R.R. Co., 966 S.W.2d 467, 469-71 (Tex.1998); 42 C.J.S. Implied and Constructive Contracts § 29 (2007) (“A claim for unjust enrichment may be had where overpayment was made under a valid contract.”). BP argues that Cash-man is a proper party for BP’s quasi-contract theory because Cashman received more than $12 million in overpayments to which it is not entitled and it is well established that claimants may recover overpay-ments by asserting quasi-contract claims even where there is a valid contract. # 91, Ex. 1, April 3, 2012 Audit Letter to Cash-man, Bates No. JV000331-336. Moreover, BP seeks damages against Cashman in all its potential capacities, including its capacity as a secondary obligor if the joint venture is insufficient to satisfy its claim.
Cashman’s Reply
Cashman insistently reiterates that contrary to BP’s argument, the MSC unambiguously dictates that the contract is by and between BP and the Joint Venture in the heading of the contract, in the preamble and on the Work Releases. It is also the only reasonable construction of the contract.
BP now seeks to sue Cashman in all capacities and for quasi contract, but it cannot because Cashman was not a party to the contract. BP has acknowledged that Cashman was acting in a representative capacity only: its Amended Complaint states that “the July Work Releases were executed by Cashman. As a principal of Cashman/LAD, Cashman had the authority to contractually bind Cashman/LAD.” # 12, ¶ 23. Contrary to BP’s argument that it does not matter if it is suing Cash-man as a Contractor or in a secondary capacity, as BP cannot sue Cashman for a breach of contract when Cashman was not a party to the Contract. Cashman quotes from BP’s motion to dismiss (# 52 at p. 5) to show that BP knows that the Joint Venture is the party that invoiced BP at the wrong rate: “The only question in this *897lawsuit is whether Joint Venture must return a portion of the funds obtained by invoicing BP at the Modified daily Rate (or higher) where it should have been invoicing BP at the reduced Standby Rate.” In BP’s response to Defendants’ motion for leave to file second amended answers (# 75 at p. 12), BP stated, “BP has not sued them [Cashman and LAD] as sureties or secondary obligors,” but rather it has sued Cashman “directly for breach of contract, for return of monies wrongly received, and for unjust enrichment.” It then backtracked on this assertion. BP’s Sur-reply, # 87 (“reaffirming] its intent to hold Cashman and LAD liable in all capacities for all damages alleged in the Complaint”). Regardless, the applicable joint venture law restricts any claim BP has against Cashman and precludes the present claims BP brings against it.
Regarding BP’s argument that it has quasi contract claims against Cashman, Cashman points out that in each of the cases relied upon by BP the quasi contract claim for overpayment was made against an actual party to the contract in dispute, not the ease here. Thus the quasi contract claims against Cashman must be dismissed.
BP submits three exhibits (# 91, Exhibits 1, Audit Letter; 6, a magazine article about Gulp skimmers; and 7, Westlaw corporate records of Gulp Oil Skimmers LLC) to support its quasi contract claims against Cushman. Cushman contends that because the contract is unambiguous, the Court does not need to review extraneous evidence. Moreover the exhibits are unauthenticated hearsay and are not relevant. Furthermore none of the three shows what BP claims it demonstrates. BP also claims that Gulp Oil Skimmers LLC does not impact the party with which BP contracted in this case, the Joint Venture.
Court’s Decision
The threshold issue to be resolved here is which entities are parties to the MSC, or, in what capacity is BP suing Cashman? The record reflects that BP has changed its mind during the course of the litigation.
The governing pleading is BP’s Amended Original Complaint (# 12), which simply states in ¶ 49 that “BP demands judgment against Defendants, jointly and severally....” In its response to Defendants’ motions for leave to file second amended answers (# 87 at p. 12), BP argues that the motion should be denied in part because allowing Defendants to assert the affirmative defense of discussion, a right only of a secondary obligor, is not available because “Cashman and LAD are not entitled to discussion because BP has not sued them as sureties or secondary obligors. Rather, BP has sued them directly for breach of contract, for return of monies wrongly received, and for unjust enrichment. ECF No. 12, ¶¶ 41-55.” In its surreply to Defendants’ motions for leave to file second amended answers (# 87 at p. 1), BP “reaffirms its intent to hold Cashman and LAD liable in all capacities for all damages alleged in the Complaint.” In its Response in Opposition to Cashman’s motion for summary judgment (# 91 at p. 5), BP asserts that “it seeks damages against Cush-man in all capacities, including (if necessary) its capacity as a secondary obligor.” Clearly there are genuine issues of law and fact here.
Related to the issue of capacity and the affirmative defense of discussion, in its opposition (# 75 at pp. 11-13) to Cashman’s motion for leave to file a Second Supplemental and Amended Answer, Affirmative Defenses [Discussion under Louisiana Civil Code Art. 5151] and Counterclaim (# 73), BP correctly pointed out that “federal law, rather than state law, invariably governs procedural matters in *898federal courts.” Camacho v. Texas Workforce Com’n, 445 F.3d 407, 409 (5th Cir. 2006), citing Motorola Communications & Electronics, Inc. v. Dale, 665 F.2d 771, 774 (5th Cir.1982). BP therefore contended that the Court should deny the motion for leave to amend because asserting the affirmative defense of discussion was a futile attempt to apply a Louisiana state court procedural mechanism to this proceeding, which instead is governed by maritime and/or Texas law, as expressly stated in the MSC, §§ 24.02 and 24.03. Nevertheless Judge Stacy granted the motion.
The fact that Cashman pleaded the affirmative defense of discussion, however, does not mean that it applies here as matter of law. As indicated in the summary of relevant law, maritime law, a constant, fundamental premise “is that the uniformity of admiralty law must be preserved and that state law may be applied only where it works no ‘material prejudice to the essential features of the general maritime law.’ That uniformity is not to be sacrificed to accommodate state law is a fundamental premise of admiralty jurisdiction.” Green v. Vermilion Corp., 144 F.3d 332, 341 (5th Cir.1998), citing John Baizley Iron Works v. Span, 281 U.S. 222, 50 S.Ct. 306, 74 L.Ed. 819 (1930), and Grant Gilmore & Charles L. Black, Jr., The Law of Admiralty § 6-58 to 6-61 (2d ed.1975); Curtis Callais Welding, Inc. v. Stolt Comex Seaway Holdings, 129 Fed.Appx. 45, 52-53 (5th Cir.2005).
The Court agrees with BP. In a diversity action where the underlying cause of action is based on state law, federal courts apply state procedural law. Deretich v. City of St. Francis, 149 F.3d 1187 (Table), Nos. 97-3925 and 97-2497, 1998 WL 327207, at *2 (8th Cir. June 19, 1998), citing Walker v. Armco Steel Corp., 446 U.S. 740, 751-53, 100 S.Ct. 1978, 64 L.Ed.2d 659 (1980). In actions brought in federal court based on federal question, however, that principle does not apply. West v. Conrail, 481 U.S. 35, 39 & n. 4, 107 S.Ct. 1538, 95 L.Ed.2d 32 (1987).16 Moreover, as noted, admiralty cases in federal court are governed by federal substantive and procedural law. S.S. Philippine Jose Abad Santos v. Bannister, 335 F.2d 595, 597 (5th Cir.1964).17 “Strict local rules of pleading cannot be used to impose unnecessary burdens upon the rights of recovery authorized by federal laws.... Should this Court fail to protect federally created rights from dismissal because of over-exacting local requirements for meticulous pleadings, desirable uniformity in adjudication of federally created rights could not be achieved.” Brown v. Western Ry. of Ala., 338 U.S. 294, 298-99, 70 S.Ct. 105, 94 L.Ed. 100 (1949).
The right of the affirmative defense is a procedural mechanism contained within the Louisiana Code of Civil Procedure art. 5151 [emphasis by the Court] and is a procedural rule. The Court concludes that the procedural rule of discussion for Louisiana joint venture/partnership liability is inapplicable here.
*899Furthermore, the substantive law, embodied in Louisiana Civil Code art. 2817 and Revision Comments, makes a partnership, and thus a joint venture, the principal obligor for its debts. Its provision that if found liable, each individual partner may be secondarily liable for only its virile share of the debts of the partnership is peculiar to Louisiana, and in the absence of general federal maritime law on partnership liability, is inconsistent with Texas law and general contract law, which would impose joint and several liability on all partners. Thus in deference to general maritime law’s emphasis on uniformity, not to be sacrificed to accommodate state law, the Court finds that secondary liability for virile share, too, is inapplicable here. Furthermore it notes that despite extensive research it has failed to find a single case in admiralty outside of Louisiana courts where the Louisiana procedural mechanism of discussion or the substantive partnership law of virile share was applied.
A Texas partnership is also “an entity distinct from its partners.” Tex. Bus. Orgs.Code § 152.056. Texas adopted the entity theory of partnership when it adopted the Revised Uniform Partnership Act (“TRPA”), codified it in the Texas Business Organizations Code. American Star Energy and Minerals Corp. v. Stowers, 457 S.W.3d 427, 429 (Tex. 2015). Under the TRPA, a partner is jointly and severally liable for all obligations of the partnership. Id., citing Tex. Bus. Orgs.Code § 152.304(a). “ ‘A judgment against a partnership is not by itself a judgment against a partner.’ ” Id., citing id. § 152.306(a). A creditor may seek to obtain a judgment against a partner or partners, individually, in the suit simultaneously against the partnership or in a separate suit. Id. at 429-30, citing id. § 152.305. Nevertheless, it may not “seek satisfaction of the judgment against a partner until a judgment is rendered against the partnership.’ ” Id. at 420, citing id. § 152.306(b) (2)(A). Generally under the TRPA “the judgment against the partnership must go unsatisfied for ninety days before a creditor may proceed against a partner and his assets.’ ” Id., citing id. § 152.306(b)(2)(C). Thus the Court concludes that BP has properly sued the partnership and the individual partners simultaneously.
Regarding the issue of the individual signatures of Cashman and LAD on the MSC without mention of the Joint Venture, it is long established under Texas law that the failure to include the partnership name is immaterial if all the partners have signed the contract: “[t]he fact that both partners signed the contract, and did not sign the partnership name, by one or both, is without legal significance so far as the application of the general rule that in partnership affairs each partner is the agent of the other, is concerned.” Pegues v. Dilworth, 134 Tex. 169, 132 S.W.2d 582 (Comm’n App.1939); 68 CJS Partnership § 193 (database updated June 2015). The Court concludes that the two signatures of the attorneys for Cashman and Lad binds the Joint Venture and the two two joint venturers in all capacities.
Last of all, the Court agrees with BP that as a matter of law the quasi contract claims of money had and received and unjust enrichment are properly brought along with a breach of contract claim under Fifth Circuit and Texas law when the issue is overpayment.
Accordingly, for the reasons stated above, the Court
ORDERS that Cashman’s motion for summary judgment is DENIED.
