Pleading and Proving Unjust Enrichment Claims

Thomas J. Hall and Judith A. Archer

The doctrine of unjust enrichment allows a plaintiff to recover from a defendant, without the benefit of an enforceable contractual obligation, where the defendant has unfairly benefited from the plaintiff’s efforts without compensation. In New York, the elements of an unjust enrichment claim are “that (1) the other party was enriched, (2) at that party’s expense, and (3) that it is against equity and good conscience to permit the other party to retain what is sought to be recovered. Mandarin Trading Ltd. v. Wildenstein, 16 N.Y.3d 173, 182 (2011).

As the viability of an unjust enrichment claim depends on broad considerations of equity and justice, several factors can drive the determination of whether these elements are adequately pleaded or later proven. For one, a close relationship between the plaintiff and defendant is required. In addition, the plaintiff’s actions must have been induced in reliance on that relationship. Finally, essential to the claim is the absence of a valid contractual relationship governing the acts giving rise to the claim. We examine below recent Commercial Division decisions addressing the application of these factors.

Degree of Relationship



The degree of the relationship between the parties necessary for an unjust enrichment claim has been heavily litigated in New York case law. The courts have routinely held that an unjust enrichment claim may not survive dismissal where the parties’ alleged relationship is “too attenuated.”

Instead, an unjust enrichment claim requires a close relationship between parties. In Sperry v. Crompton, 8 N.Y.3d 204 (2007), the plaintiff, the purchaser of tires, asserted an unjust enrichment claim against the producers of chemicals used to manufacture the tires. The plaintiff alleged that those producers engaged in a price fixing conspiracy that inflated the cost of tires to consumers and unjustly enriched the defendants. In affirming dismissal of that claim for lack of a sufficient relationship, the Court of Appeals reasoned that, “while we agree … that a plaintiff need not be in privity with the defendant to state a claim for unjust enrichment … the connection between the purchaser of tires and the producers of chemicals used in the rubber-making process is simply too attenuated to support such a claim.”

In a more recent case, Georgia Malone & Co. v. Rieder, 19 N.Y.3d 511 (2012), the Court of Appeals likewise held that while a “plaintiff is not required to allege privity, the pleading must assert a connection between the parties that is not too attenuated.” In Mandarin Trading Ltd v. Wildenstein, the Court of Appeals held that an unjust enrichment claim must plead facts “that would indicate a relationship between the parties, or at least an awareness by” the defendant of the plaintiff’s existence. 16 N.Y.3d at 182. A defendant’s awareness, however, requires more than a mere knowledge of the other party’s existence. Georgia Malone & Co., Inc. v. Rieder, 19 N.Y.3d 511 (2012).

Following this precedent, in Robinson v. Oz Master Fund, Ltd., No. 654009/2013, 2015 WL 6126956, at 5 (N.Y.Co. Oct. 16, 2015), Justice Saliann Scarpulla of the New York County Commercial Division concluded that the defendants’ alleged connection to plaintiffs was too weak to sustain plaintiff’s claim for unjust enrichment. Although a complex fact pattern, the plaintiff, the beneficiary of notes on which a bankrupt third party had defaulted, essentially alleged that other creditors of that third party who received payment on their claims were unjustly enriched. The court dismissed that claim finding that the defendants’ connections to plaintiffs were indirect, through other entities, and thus were too weak to support the claim.
