OPINION AND ORDER
I. INTRODUCTION
Sagi Genger (“Genger”) and TPR Investment Associates, Inc. (“TPR,” together *584“third-party plaintiffs”) bring this action seeking enforcement of a promissory note and contribution and/or indemnification against third-party defendant Gilad Sharon, Sharon now moves for summary judgment seeking to dismiss the third-party plaintiffs’ complaint in its entirety on the ground that the claims are precluded by the final judgment in a state court case involving the same parties. For the following reasons, the motion for summary judgment is denied.
II. BACKGROUND
This lawsuit arises out of a Canadian real estate venture (“AG Properties”) between Gilad Sharon and Sagi Genger’s father, Arie Genger.1 In 2001, AG Properties was incorporated in Nova Scotia.2 Arie Genger served as its sole director.3 Later in 2001, AG Holdings, another corporation under the sole directorship of Arie Genger, acquired all of the shares of stock in AG Properties.4 During 2001 and 2002, AG Properties acquired the entire beneficial interest in two pieces of real property located in Montreal, Canada (the “Durocher” and “Lincoln” properties).5 TPR, a Delaware corporation beneficially owned at the time by Sagi Genger and other members of the Genger family, provided AG Holdings the mezzanine debt financing necessary to acquire the property.6 The properties were placed in trust in 2002 (the “Lincoln” and “Durocher” Trusts).7
Genger now alleges that Sharon held a fifty percent interest in AG Properties through Omniway, a Cypriot company.8 Genger alleges that Sharon purchased the stake .with a $1.25 million promissory note (the “Omniway Note”) secured by his shares in AG Properties.9 The Omniway Note was ’executed on February 6, 2002.10 The Note provided that the principal sum would be paid in three annual installments of $125,000 on July 24, 2008, July 24, 2009, and July 24, 2010, with .the outstanding principal sum due on July 24, 2011.11 Additionally, interest of 6.5% per year was due annually beginning on July 24, 2003.12
The Omniway Note contained an acceleration clause allowing AG Properties to recover the entire unpaid principal amount and all other amounts payable in an Event of Default:
Upon the occurrence of any Event of Default, the entire unpaid principal balance and all other amounts payable hereunder shall become immediately due and payable, in the case of an Event of Default specified (i) in clause (a) above, at the option of Payee; and (ii) in clauses (b) or (c) above, ipso facto upon occurrence of the Event of Default and without notice, demand, or any further or other action of the payee.13
Clause (a) of the Omniway Note defines an Event of Default as: “Maker’s failure to pay any of the principal of this Note when *585due and payable or Maker’s failure to pay any interest on this Note when due and payable and such failure to pay interest shall continue for thirty (30) days.”14 Neither Omniway nor Sharon have made any of the principal or interest payments due under the Omniway Note.15
In 2003, Arie Genger and Sharon agreed to substitute Lerner Manor, an Israeli company, for Omniway as a fifty percent stockholder of AG Properties for $25,000 consideration.16 As a result, Sagi Genger alleges that he had no knowledge of the Omniway Note prior to this litigation.17 In 2004, at the direction of Arie Genger, Lerner Manor was retroactively substituted as a fifty percent interest holder in both the Lincoln and Durocher Trusts for the stated consideration of ten dollars.18
In 2004 and 2005, AG Properties sold the Lincoln and Durocher properties for a profit.19 AG Properties then gave one million dollars of the proceeds to AG Holdings, which used that money to purchase Lerner Manor’s fifty percent interest in AG Properties as well as Lerner Manor’s fifty percent stake in the Lincoln and Durocher Trusts from Lerner Manor.20 Sharon received the proceeds from these transactions.21
On October 22, 2007, TPR, AG Properties, Dalia Genger, and D & K Limited Partnership (“D & K”) filed an action in Supreme Court, New York County, against Sharon and Lerner Manor alleging fraud, aiding and abetting breach of fiduciary duty, unjust enrichment, and conversion.22 On July 10, 2009, the Supreme Court dismissed the Complaint on the grounds that a 2008 divorce arbitration between Arie Genger and his former wife, Dalia Genger, precluded the claim.23 The divorce arbitration stemmed from a settlement stipulation that called for a fifty-fifty distribution of marital assets between Arie and Dalia Genger.24 Following the distribution of marital property pursuant to the settlement, Dalia Genger alleged that Arie Genger had undervalued and concealed assets, including the Canadian real estate venture.25 The arbitrator determined that she “never had any real or equitable marital interest in the Canadian venture.”26 On September 8, 2011, the Appellate Division affirmed the Supreme Court’s dismissal of the complaint.27
*586Vladimir Gusinski, a creditor of AG Holdings, brought a claim for fraudulent conveyance against Genger in this Court in 2010.28 Gusinski extended a $2.5 million loan to AG Holdings in 2001' After AG Holdings defaulted in payment, Gusinski obtained a judgment for approximately $4.35 million in the Supreme Court of the State of New York.29 In the federal court action; Gusinski alleged that Genger intentionally depleted AG Holdings’ assets to render it incapable of repaying the loan.30 Genger then filed a third-party complaint against Lerner Manor, Omniway, and Sharon seeking enforcement of the Omniway Note and contribution and/or indemnification relating to Gusinski’s claim.31 On May 6, 2011, Genger settled the primary lawsuit with Gusinski for a sum of money.32 Sharon now moves for summary judgment on Genger’s claims. .
III. LEGAL STANDARD ON A MOTION FOR SUMMARY JUDGMENT
Summary judgment in a defendant’s favor is appropriate only if “there is no genuine dispute as to any material fact and [defendant is] entitled to judgment as a matter of law.”33 “An issue of fact is genuine if the evidence is such that a reasonable jury could return a verdict for the nonmoving party. A fact is material if it might affect the outcome of the suit.”34 Because Sharon is moving for summary judgment, he “bears the burden of establishing the absence of any genuine issue of material fact.”35 To defeat Sharon’s motion, third-party plaintiffs “ ‘must do more than simply show that there is some metaphysical doubt as to the material facts,’ ”36 and “may not rely on conclusory allegations or unsubstantiated speculation.”37
In deciding these motions, I must “construe the facts in the light most favorable to the non-moving party,” that is, to plaintiffs, “and [] resolve all ambiguities and draw all reasonable inferences against the movant,” that is, against the defendant.38 “The role of the court is not to resolve disputed issues of fact but to assess whether there are any factual issues to be tried.”39 “ ‘Credibility determinations, the weighing of the evidence, and the drawing of legitimate inferences from the facts are jury functions, not those of a judge.’ ”40
IV. APPLICABLE LAW
A. Claim Preclusion
“When a claim has been fully litigated, the doctrine of claim preclusion generally bars the future litigation both of *587that claim and of any closely related claims.”41 A “federal court must give a state court judgment the same preclusive effect as would be given a judgment under the law of the State in which the judgment was rendered.”42 Because the relevant antecedent judgment in this case occurred in New York state court, New York law governs the law of preclusion.
New York “has adopted a transactional approach to claim preclusion.”43 Under that approach, “once a claim is brought to final conclusion all other claims [between the same parties] arising out of the same transaction or series of transactions are barred, even if based upon different theories or if seeking a different remedy.”44 “A pragmatic test [is] applied to make this determination—analyzing whether the facts are related in time, space, origin, or motivation, whether they form a convenient trial unit, and whether their treatment as a unit conforms to the parties’ expectations or business understanding or usage.”45
“The primary purposes of [claim preclusion] are grounded in public policy concerns and are intended to ensure finality, prevent vexatious litigation and promote judicial economy.”46 However, courts must be careful not to apply the doctrine “too harshly”, and thus, “ ‘[i]n properly seeking to deny a litigant two days in court, ... deprive [the litigant] of one.’ ”47
B. Contribution
Contribution provides that one of two or more joint wrongdoers should not be required to pay more than its share of a common burden.48 Accordingly, contribution is allowed only among joint tortfeasors.49 “The definition of a joint tortfeasor is fairly broad. A finding of liability is not required.”50 Therefore, the fact that the prior action in which Gusinski alleged tortious conduct settled, making an ultimate determination of liability unavailable, does not preclude a contribution action.51
C. Indemnification
Under New York Law, indemnity is a restitution concept permitting shifting the loss to avoid the unjust enrichment of one party at the expense of the other.52 Although indemnification claims usually arise from an express agreement by which one party agrees to hold the other harmless for claims brought against it by a third-party,53 in the absence of an express *588contractual provision for indemnification, an implied right of indemnification can still be found.54 A person is entitled to implied indemnity when he, “ ‘in whole or in part, has discharged a duty which is owed by him but which as between himself and another should have been discharged by the other.’ ”55
Interpreting New York law, the Second Circuit has identified two sets of circumstances in which a right to implied indemnification may exist. First, indemnification can be implied from the special nature of a contractual relationship between two parties; this has been called the “implied contract theory.”56 Second, indemnification can be implied when there is a great disparity in the fault of two tortfeasors, and one of the tortfeasors has paid for a loss that was primarily the responsibility of the other; this tort-based doctrine has been called “implied-in-law” indemnity.57
V. DISCUSSION
A. Claim Preclusion
The parties agree that Genger and Sharon were both parties to the 2007 state law claim and that the state court dismissal constituted a final judgment on the merits.58 Sharon argues that this judgment precludes Genger’s current claim for two reasons. First, Genger’s claims stem from the same series of transactions at issue in the prior suit — Sharon’s investment in AG Properties — and thus cannot be brought under a new legal theory.59 Second, Genger could have brought the claim for enforcement of the Omniway Note in the prior suit because Sharon had defaulted on his interest payments. Accordingly, Sharon argues, Genger had the option to demand payment of the entire unpaid principal balance and all other amounts payable under the Note’s acceleration clause.60
1. The 2007 Lawsuit Does Not Preclude Genger’s Claim for Enforcement of the Omniway Note
Sharon’s investment in AG Properties through the Omniway Note constitutes a distinct transaction from the one at issue in the state court action. The state court action alleged that Sharon defrauded TPR, AG Properties, Dalia Genger, and D & K out of the proceeds from the Canadian real estate venture through a sham transaction.61 That transaction, the substitution of Lerner Manor as a fifty percent shareholder in AG Properties for $25,000 consideration, took place in 2003.62 Genger now alleges that Sharon made a bona fide investment in AG Properties via the Omniway Note in 2002. Because the state court action did not address the Omniway Note, litigating its enforcement now will not “ ‘destroy or impair rights or interests’ ” established in that judgment.63 That both the state court action and Genger’s current claim involved “essentially *589the same course of wrongful conduct”— Sharon’s investment in AG' Properties— does not preclude the current action.64 Because the Omniway Note involved a separate transaction than the one at issue in the state court action, Genger’s current action does not constitute claim-splitting.65
Moreover, the claims raised in the state court action required different evidence to support them than Genger’s current claim.66 To enforce the Omniway Note, Genger must demonstrate that it was a valid contract supported by consideration. In contrast, the state court fraud claim alleged that Sharon aided in preparing phony documents in 2003,67 Plaintiffs’ unjust enrichment claim in the 2007 state court action disputed the existence of a valid contract between Sharon and AG Property for the purposes of the 2003 transaction.68 Genger now asserts that the parties executed a different but valid contract in 2002 and seeks to enforce it.69 The 2007 conversion claim alleged an unauthorized possession of the proceeds from the Canadian real estate venture by Sharon, rather than the existence of a legitimate investment in. the form of a promissory note.70 Finally, plaintiffs’ breach of fiduciary duty claim in the 2007 state court action alleged that Sharon aided Arie Genger in breaching his duty to TPR by participating in the 2003 transaction.71 This requires showing that the 2003 transaction constituted that breach, that Sharon participated in the breach, and that the plaintiffs suffered damages as a result.72 Neither the earlier unjust enrichment claim *590nor the breach of fiduciary duty claim requires the same evidence as Genger’s current claim for enforcement of the Omniway Note, nor did they' implicate the transaction now at issue.
2. The Omniway Note’s Acceleration Clause Does Not Bar Genger’s Enforcement Claim
Res judicata bars claims that parties could have raised in prior actions.73 However, that parties in privity with Genger could have brought a claim to enforce missed interest payments on the Omniway Note prior to 2008 does not mean that they were required to bring claims' arising from Sharon’s prospective default on payments not yet due in 2008.74 While the Omniway Note gave the payee the option to accelerate payments,‘it did not require the payee to do so.75 Genger retained the option to allow the Note’s principal to continue accumulating interest rather than cutting his losses and suing for enforcement of the lesser amount due in 2007. That he exercised this right does not require this Court to deny him the benefit of the bargain.
Moreover, the confusion surrounding Omniway’s role in the Canadian real estate venture calls into question whether any of the plaintiffs in the 2007 lawsuit could have raised the issue of the Omniway Note in that litigation. As recently as 2011, Sharon denied knowledge of the Omniway Note.76 Moreover, extensive discovery efforts throughout this litigation and a sanction from this Court precluding Sharon from testifying regarding the existence of the'Omniway Note were necessary to establish the Note’s existence.77 Accordingly, denying Genger the opportunity to litigate the Note’s enforcement in the case at hand would deprive a litigant of the chance to bring a claim rather than preserve the finality of a previous judgment.78
3. Res Judicata Does Not Bar Genger’s Claim for Indemnification and/or Contribution
Res judicata does not bar Genger’s claim for indemnification and/or contribution because the claim stems from a 2011 settlement between Genger and Gusinski.79 Because both the indemnification *591and contribution claims attempt to shift the cost of tortious conduct established in 2011 from Genger to Sharon, they could not have been brought in 2007.80
B. Indemnification and/or Contribution
1. Sharon Failed to Challenge Genger’s Indemnification Claim in His Motion for Summary Judgment
Sharon argues in his reply brief that the Third-Party Complaint does not state a claim for indemnification under New York law.81 The Court does not consider this argument because Sharon did not raise it in his motion for summary judgment.82
2. Genger States a Claim for Contribution Under New York Law
Sharon also argues that the Third-Party Complaint does not plead a claim for contribution because New York law permits contribution only among joint tortfeasors.83 While true, the settlement giving rise to Genger’s contribution claim concerned Gusinski’s fraudulent conveyance action. Under New York law, fraudulent conveyance sounds in tort, not contract.84 Unlike Genger’s claim for enforcement of the Omniway Note, which stems from the contract itself, the claim for contribution seeks to force Sharon to share the cost of settling Gusinski’s tort action. Accordingly, Genger states a claim for contribution under New York law.
VI. CONCLUSION
For the foregoing reasons, third-party defendant’s motion for summary judgment is denied. The Clerk of the Court is directed to close the motion for summary judgment. (Docket Entry # 130). A conference is scheduled for November 29 at 3:30.
SO ORDERED.
