MEMORANDUM OF DECISION
In this adversary proceeding, the chapter 7 trustee (the “Trustee”) for the above-referenced debtor’s (the “Debtor”) estate seeks avoidance of certain transfers (the “Transfers”) and recovery of $23,871.54 (plus interest and costs) as preferences paid to the above-referenced defendant (the “Defendant”) involving, inter alia, three checks made payable to the Defendant and the Debtor jointly. The court has jurisdiction over this adversary proceeding as a core matter pursuant to 28 U.S.C. §§ 1334 and 157(b), and that certain Order dated September 21, 1984 of the District Court (Daly, C.J.)1 This memorandum constitutes the findings of fact and conclusions of law mandated by Rule 7052 of the Federal Rules of Bankruptcy Procedure.
I. BACKGROUND
The Debtor commenced this chapter 7 case on June 18, 2004. (See Case Doc. I.D. No. 2.)2 Roberta Napolitano, Esq. is the Trustee. The Trustee commenced this adversary proceeding under 11 U.S.C. §§ 547 and 550(a)3 by the filing of a complaint (A.P. Doc. I.D. No. 1, the “Complaint”) on April 7, 2005. The Defendant filed its answer (A.P. Doc. I.D. No. 7, the “Answer”) on May 10, 2005. The Answer denied certain material allegations of the Complaint but did not allege any affirmative defenses under Bankruptcy Code § 547(c). (See Answer.)
The trial (the “Trial”)4 on the Complaint was held on November 28, 2005. At the Trial, the Trustee introduced her own testimony and the testimony of the Debtor’s principal, Robert Patton. The Defendant introduced the testimony of Timothy King, the Defendant’s president. Both parties introduced documentary evidence into the record at Trial.5 The Trial record subse*621quently was supplemented pursuant to a certain evidentiary Stipulation (A.P. Doc. I.D. No. 28, the “Stipulation”). Post-Trial briefing has been had6 and the matter is ripe for decision.
II. FACTS7
Some time prior to the petition date, FIP Construction, Inc. (“FIP”), as prime contractor, entered into the following construction contracts (the “Contracts”) with the following owners (collectively, the “Owners”): (a) a contract with Wesleyan University for a project (the “Wesleyan Project”) generally referred to as “Center for Film Studies;” (b) a contract with Quin-nipiac University for a project (the “Quin-nipiac Project”) generally referred to as “Development & Public Affairs Building;” and (c) a contract with The Elim Park Baptist Home, Inc. for a project (the “Spring Meadow Project,” collectively with the other two projects, the “Projects”) generally referred to as “Spring Meadow.” (See Stipulation (Trustee Exh. 21, 22, 23).) Subsequently FIP entered into the following subcontracts (collectively, the “Subcontracts”) with the Debtor (as “mechanical subcontractor”)8: (a) Subcontract dated May 21, 2003 with respect to the Wesleyan Project; (b) Subcontract dated June 3, 2003 with respect to the Quinnipiac Project; and (c) Subcontract dated April 9, 2003 with respect to the Spring Meadow Project. (See Stipulation (Trustee Exh. 21, 22, 23); Transcript at 9 (testimony of Mr. Patton).) Subsequently, the Debtor entered into agreements (either by purchase orders or otherwise, the “Supply Agreements”) with the Defendant pursuant to which the Defendant agreed to supply certain materials and/or services for each of the Projects for certain consideration to be paid by the Debtor. (See Transcript at 29-30 (testimony of Mr. King).)
The Defendant performed under the Supply Agreements and issued the following invoices to the Debtor: (a) an invoice dated November 17, 2003 (with a “ship date” of October 17, 2003) with respect to the Wesleyan Project in the amount of $8,082.00 (Trustee Exh. 2); (b) an invoice dated December 15, 2003 (with a “ship date” of December 9, 2003) with respect to the Quinnipiac Project in the amount of $4,800.00 (Trustee Exh. 8); and (c) an invoice (the “Spring Meadow Project Invoice” collectively with the other two invoices, the “Invoices”) dated November 17, 2003 (with a “ship date” of November 5, 2003) with respect to the Spring Meadow Project in the amount of $18,120.009 (Trustee Exh. 14).
The Debtor fell into financial difficulty in approximately February of 2004. (See Transcript at 8 (testimony of Mr. Patton).) Around that time, Mr. King (at the Defendant) “contact[ed] ... [Mr. Patton at the *622Debtor] to see about ... [the Defendant’s] getting paid for ... [the Invoices] after so much time had gone by.” (Transcript at 32:22-23 (testimony of Mr. King); see also Transcript at 33:2-8 (testimony of Mr. King).) Mr. Patton told Mr. King that “there was some difficulty that ... [the Debtor] had and that ... [the Defendant] should contact FIP, that they ... were offering to negotiate those invoices.” (Transcript at 33:10-15 (testimony of Mr. King).) At that time, FIP owed money to the Debtor under each of the Subcontracts which receivables included the amounts owing by the Debtor to the Defendant pursuant to the unpaid Invoices.10 (See Transcript at 12-18) (testimony of Mr. Patton). Mr. King then had one or more “follow-up” conversations with FIP. (Transcript at 34 (testimony of Mr. King).) Those conversations resulted in a meeting between representatives of FIP and the Defendant at FIP’s offices on May 12, 2004 (the Debtor was not represented at that meeting). (See Transcript at 34-36 (testimony of Mr. King).)
In preparation for that meeting, either FIP or the Debtor had prepared a form of “Joint Pay Agreement^] Prime Contractor/Subcontractor/Supplier” (each hereafter referred to as a “JPA” and discussed further below) for each of the Projects and, for each Invoice, FIP had issued a check (each dated April 27, 2004, a “Joint Check”) made payable jointly to the Debt- or and the Defendant in the reduced amounts alleged in Exhibit A to the Complaint. The Debtor had signed each of the JPAs and endorsed each of the Joint Checks at FIP’s offices on April 28, 2004 and had left all of the foregoing there. (See Transcript at 23 (testimony of Mr. Patton); Transcript at 36-37 (testimony of Mr. King); see also Trustee Exh. 3, 9, 15.) Presumably, FIP had prepared the forms of the lien waivers and general releases described below. When Mr. King arrived at FIP’s offices on May 12, 2004, the partially executed JPAs, the partially endorsed Joint Checks and the forms of lien waivers and general releases all were waiting for him. (See Transcript at 40 (testimony of Mr. King).)
At or before the meeting, FIP’s representative told Mr. King that the Defendant could have a seventy-seven cent (77$) on the dollar payment on the Invoices (ie., payment in the aggregate amount of the Joint Checks endorsed by the Debtor) if the Defendant would execute and deliver lien waivers and general releases to FIP. (See Transcript at 38-39 (testimony of Mr. King).) On behalf of the Defendant, at the May 12, 2004 meeting Mr. King signed the JPAs, executed lien waivers with respect to each of the Projects (as discussed further below), executed general releases of FIP and each of the Owners (as discussed further below) and delivered all of the foregoing to FIP. (See Trustee Exh. 3, 9, 15; Defendant Exh. A, B, C.) Mr. King then was given the partially endorsed Joint Checks, took them back to his office and they were deposited into the Defendant’s bank account. (See Transcript at 39 (testimony of Mr. King).)
III. THE JPAs, THE LIEN WAIVERS AND THE RELEASES
Each of the JPAs provides in relevant part as follows:
“[T]o induce ... [the Defendant] to furnish the above items,f11] [the Debtor] *623... requests and authorizes ... [FIP] to issue all applicable payment checks jointly payable to ... [the Debtor and the Defendant] in the amounts specified in ... [the Debtor’s] billings.... No funds will be paid to ... [the Defendant] in excess of that which is due on this particular job. This agreement to pay by joint check is made solely as an accommodation and is not intended to create in any way a contractual relationship, direct or indirect, between ... [FIP and the Defendant] and/or any of its subsidiaries. Furthermore, all payment terms as contained in the contract between ... [FIP and the Debtor] remain in effect.
[The Debtor] shall forward to ... [FIP] a copy of the invoice from ... [the Defendant] indicating the joint check amount. All joint checks shall be delivered to [the Debtor] for endorsement and forwarded to the ... [Defendant] .... This Joint Pay Agreement is not revocable, until all parties agree in writing.
(Trustee Exh. 3, 9,15).
Each lien waiver (a “Lien Waiver”) provides that the Defendant
waived, relinquished, and released and do[es] hereby waive, relinquish, and release all liens and claims of liens we now have or may hereafter have upon ... [the respective Project] for labor done or to be done and materials furnished or to be furnished in the erection, construction or repair of said ... [Project].
(Defendant Exh. A, B, C.)
Each general release (a “General Release”) provides that the Defendant
remised, released and forever discharged ... FIP ... [and the respective Owner], their predecessors, successors, assigns, affiliates, subsidiaries, directors, officers, employees, agents, all related insurers, underwriters, sureties, and financial sources of all listed parties, of and from all, and all manner of action and actions, cause and causes of action, suits, debts, dues, sums of money, accounts, reckoning, bonds, bills, specialties, covenants, contracts, controversies, agreements, promises, variances, trespasses, damages, judgments, extents, executions, claims and demands whatsoever, in law, or equity, which ... [the Defendant] ever had, now has or which it or its successors, subsidiaries and related parties, heirs and assigns hereafter can, shall or may have for, upon or by reason of or in connection with the construction of the ... [respective Project].
(Defendant Exh. A, B, C.)
IV. ANALYSIS
A. Applicable Law and Standards
Bankruptcy Code § 547(b) provides in relevant part as follows:
(b) Except as provided in subsection (c) of this section, the trustee may avoid any transfer of an interest of the debtor in property—
(1) to or for the benefit of a creditor;
(2) for or on account of an antecedent debt owed by the debtor before such transfer was made;
(3) made while the debtor was insolvent;
(4) made—
(A) on or within 90 days before the date of the filing of the petition ...; and
*624(5) that enables such creditor to receive more than such creditor would receive if—
(A) the case were a case under chapter 7 of this title;
(B) the transfer had not been made; and
(C) such creditor received payment of such debt to the extent provided by the provisions of this title.
11 U.S.C.A. § 547(b) (West 2005). “Transfer” is defined by the Bankruptcy Code to mean “every mode, direct or indirect, absolute or conditional, voluntary or involuntary, of disposing of or parting with property or an interest in property....” 11 U.S.C.A. § 101(54) (West 2005). Bankruptcy Code § 550(a) provides in relevant part:
(a) [T]o the extent that a transfer is avoided under section ... 547 ... of this title, the trustee may recover, for the benefit of the estate, the property transferred, or, if the court so orders, the value of such property, from—
(1) the initial transferee of such transfer....
11 U.S.C.A. § 550(a) (West 2005).
The burden is on the Trustee to prove by a preponderance of the evidence every element of Section 547(b) (including that the property transferred was property in which the debtor had “an interest” within the statutory purview). See, e.g., Stingley v. AlliedSignal, Inc. (In re Libby Int’l, Inc.), 247 B.R. 463, 466 (8th Cir. BAP 2000); 11 U.S.C.A. § 547(g).
B. Application of Law to Fact
The Defendant contends that the Trustee has not proved that the Transfers were of “an interest of the [Djebtor in property” within the purview of Section 547(b) and also contests other elements of a preference to the extent that they necessarily devolve from the foregoing. In furtherance of its position the Defendant argues as follows: (1) the Transfers were not of property in which the Debtor had an interest pursuant to the doctrine of “earmarking;” (2) the Debtor lacked sufficient control of the Joint Checks to give it a property interest in them within the purview of Section 547(b); and (3) the payment to the Debtor must be deemed to have been a payment of third-party (i.e., FIP’s) funds and not a payment of proceeds of the Receivables because FIP had an independent contractual duty to pay the Defendant. The court will consider each argument in turn.
1. Earmarking
The Defendant argues that there was no transfer of “an interest of the [D]ebtor in property” within the purview of Bankruptcy Code § 547(b) because the Joint Checks were “earmarked” for the Defendant.
Under the earmarking doctrine, where a third party lends money to a debtor for the purpose of paying a specific creditor, the loan is not a preferential transfer. Instead the third party simply is substituted for the original creditor....
The earmarking doctrine applies only where a third party lends money to the debtor for the specific purpose of paying a selected creditor.
Glinka v. Bank of Vermont (In re Kelton Motors, Inc.), 97 F.3d 22, 25, 28 (2d Cir.1996) (emphasis added; internal quotation marks omitted). The Joint Checks were not the proceeds of a third party loan substituting one creditor for another. Accordingly, the earmarking doctrine does not apply.
2. Lack of Control Over Joint Checks
The Defendant further argues that, because the Debtor had so little control over the Joint Checks, the Debtor had no “interest” in them for Section 547(b) pur*625poses. That argument might be more persuasive if the JPAs had been executed and delivered outside of the preference period even if the Debtor had endorsed the Joint Checks within it. That is because the Debtor might have been deemed to have transferred its interest in the Receivables pursuant to the JPAs with later endorsement of the Joint Checks (i.e., the proceeds of the Receivables) a mere formality. Cf. Herzog v. Sunarhauserman (In re Network 90°, Inc.), 126 B.R. 990 (N.D.Ill.1991).12 Here, however, the Debtor signed the JPAs and endorsed the Joint Checks at the same time and both within the preference period. When the Defendant signed the JPAs and simultaneously accepted the Joint Checks, the Debtor’s interest in the Receivables was transferred to the Defendant and that was a transfer of property of the Debtor within the preference period. Cf. Buono, 119 B.R. at 501 n. 1 (trustee prevails on similar theory).
The Defendant argues that the Trustee cannot prevail on the above theory because the Complaint does not specifically seek avoidance of the JPAs, the Trustee’s counsel did not refer to the timing of the JPAs until after all the Trial evidence had come in (except for the Stipulation) and the Defendant has been unfairly surprised.13 In another case that argument might have some appeal. However, as noted above, in this case the execution of the JPAs and the endorsement and delivery of the Joint Checks were so contemporaneous as to constitute one single occurrence. On those facts, the Defendant cannot be unfairly surprised by the Trustee’s attack on the JPAs and reference to the Joint Checks in the Complaint was sufficient notice that the entire transaction (including the JPAs) was under attack. For this court to require the Trustee specifically to seek avoidance of the JPAs in order to prevail on the Complaint would be to take an unduly technical approach which this court declines to do.
3. Independent Duty of FIP To Pay the Defendant
Finally, the Defendant argues that FIP incurred an independent contractual duty to pay the Defendant in accordance with the JPAs because the Defendant executed and delivered the Lien Waivers and the General Releases to FIP in reliance upon the JPAs. As a result, the Defendant further argues, the payments by FIP must be deemed to be payments from FIP’s own funds rather than from the proceeds of the Receivables.
It is true that, under some circumstances, courts have deemed payments by a third party contractor to a debtor’s supplier to be satisfaction of an independent contractual obligation of the contractor to pay the supplier rather than a payment from the debtor’s construction receivable. See, e.g., Shaw Industries, Inc. v. Gill (In re Flooring Concepts, Inc.), 37 B.R. 957 (9th Cir. BAP 1984).14 This court has *626some doubts that the Flooring Concepts doctrine applies when the construction receivable owing from the third-party is property of the subcontractor’s estate and the third-party’s payment is charged against that receivable. That the subject checks were made payable to the Debtor and the Defendant jointly (rather than solely to the Defendant) is evidence that the payments here were intended to be credited against the Receivables and that is consistent with Mr. Patton’s testimony. {See Transcript at 13: 2-6; 16:7-16; 18:3-17 (testimony of Mr. Patton).) Moreover, no cogent argument has been made that the Receivables were not property of the Debtor which would have become part of its bankruptcy estate upon filing. Cf. Flooring Concepts, 37 B.R. at 961 (“[T]he account ostensibly due the debtor could not have become part of the bankruptcy estate.”).
However, the court need not reach that issue because Flooring Concepts and cases similar to it are otherwise not factually apposite here. That is because in this case the Defendant did not give up its hen rights against the Projects in reliance on the JPAs and issuance of the Joint Checks but, rather, the Defendant already had forfeited such hen rights by failure to comply with applicable law as of the time it executed the Lien Waivers.15 Nor did the Defendant relinquish anything meaningful to it when it executed the General Releases 16 or when it agreed to take less than the aggregate face amount of the Invoices as a “final settlement.”17 Accordingly, the *627Defendant did not meaningfully rely upon the JPAs and issuance of the Joint Checks.18 Cf. Flooring Concepts, 37 B.R. at 961 (noting that the supplier gave up materialman’s liens which “it had a right to pursue”). Therefore, on the facts presented here, the equities do not favor deeming the payment from FIP to be payment from its own funds (rather than from proceeds of the Receivables which were property of the Debtor) as the equities might if there had been meaningful reliance by the Defendant. For the foregoing reasons, the court finds this particular argument by the Defendant to be unpersuasive.19
V. CONCLUSION
For the reasons stated above, the court concludes that a transfer of proceeds of the Receivables occurred upon the execution and delivery of the JPAs and endorsement and delivery of the Joint Checks and such was a transfer of “an interest of the [D]ebtor in property” within the purview of Section 547(b). .Based upon the foregoing and upon the Trial record, the court concludes that the Trustee successfully has carried her burden with respect to all elements of Bankruptcy Code §§ 547(b) and 550(a). The Complaint seeks interest and costs. The court exercises its discretion to award prejudgment interest on $23,871.54 from April 7, 2005 at the rate applicable as of such date under 28 U.S.C. § 1961. Cf. Hirsch v. Union Trust Co. (In re Colonial Realty Co.), 229 B.R. 567, 577 (Bankr.D.Conn.1999). The request for costs is granted. Judgment consistent with the foregoing will enter.20
