Most simply explained, a constructive trust is an equitable remedy imposed to prevent unjust enrichment (see Simonds v Simonds, 45 NY2d 233, 242 ; Sharp v Kosmalski, 40 NY2d 119 ). According to the Court of Appeals, the constructive trust is “the formula through which the conscience of equity finds expression. Where property has been acquired in such circumstances that the holder of legal title may not in good conscience retain the beneficial interest, equity converts him into a trustee” (Beatty v Guggenheim Exploration Co., 225 NY 380, 386 ).
It is an amorphous doctrine, as the constructive trust is “not limited by rigid definition and its very purpose requires flexibility in its application” (In re Alpert, 9 Misc 3d 1102[A], *10). It therefore follows that the constructive trust “has been famously described as a remedy applicable to ‘whatever knavery human ingenuity can invent’” (In re Alpert, 9 Misc 3d at *7 [Sur Ct, New York County 2005], quoting Bogert, Trusts and Trustees Sec. 471 at 29 [2d ed rev]). In fact, it is of such broad scope that attempted precise definitions have been deemed inadequate (see Simonds v Simonds, 45 NY2d 233, 241 ).
Even applicable in the case of an innocent donee, no wrongful act is necessary to find unjust enrichment warranting the imposition of a constructive trust. However, in the case of a bona fide purchaser, he or she takes property free of a constructive trust that would otherwise be imposed (5 Scott, Trusts [3d ed] sec.468).
A constructive trust “is perhaps more different from an express trust than it is similar”, in that “the constructive trustee is not compelled to convey the property because he is a constructive trustee; it is because he can be compelled to convey that he is a constructive trustee” (Simonds v Simonds, 45 NY2d 233, 241 , relying on 5 Scott, Trusts [3d ed], sec. 461-462]). Generally, the following elements must be established to state a claim for this type of relief: (1) a confidential or fiduciary relation; (2) a promise; (3) a transfer in reliance thereon; and (4) unjust enrichment (see Sharp v Kosmalski, 40 NY2d 119, 121 ). Nonetheless, unlike most causes of action, courts do not require strict satisfaction of each element, but rather use them more as flexible considerations (Lester v Zimmer, 147 AD2d 340, 341 [3d Dept 1989]).
Courts most often impose constructive trusts where traditional remedies prove inadequate or unavailable. Perhaps most illustrative in the context of trusts and estates is the landmark case of Latham v Father Divine, 299 NY 22 (1949), where the facts seemed appropriate for a claim for tortious interference with wills, a cause of action that is not recognized by New York law (see Restatement (Second) of Torts §774B [1979-2010], citing Vogt v Witmeyer, 87 NY2d 998, 999 ).
In Latham, the decedent had executed a will, but later expressed a desire to create a new testamentary instrument to contain bequests to other individuals. However, due to fraud, undue influence, and ultimately murder committed by the defendant, the decedent was prevented from executing her new will.
As is often the case where a constructive trust proves to be the appropriate remedy, the Court of Appeals recognized that there was no precedent precisely on point to address the facts presented. But the Court relied upon other well-respected authorities and explained that “[w]here a devisee or legatee under a will already executed prevents the testator by fraud, duress or undue influence from revoking the will and executing a new will in favor of another or from making a codicil, so that the testator dies leaving the original will in force, the devisee or legatee holds the property thus acquired upon a constructive trust for the intended devisee or legatee” (Latham v Father Divine, 299 NY 22 , 26 ).
In light of that rule, along with other analogous Court of Appeals decisions, the Court held that the imposition of a constructive trust was appropriate, as “its applicability is limited only by the inventiveness of men who find new ways to enrich themselves unjustly by grasping what should not belong to them” (299 NY at 27). The Court further stated that “a constructive trust will be erected whenever necessary to satisfy the demands of justice” (see id.).
In coming to its conclusion, the Court cited Matter of O’Hara’s Will, 95 NY 403 (1884), noting that the plaintiffs in that case successfully obtained a constructive trust in their favor, notwithstanding the fact that “disappointed hopes and unrealized expectations were all that the secretly intended beneficiaries, not named in the will, had,” as well as Williams v Fitch, 18 NY 546 (1859), in which the fraud “consisted of the legatee’s failure or refusal to carry out the testator’s designs, after tacitly or expressly promising so to do” (see Latham, 299 NY at 27). Notably, in Latham, there was no discussion of a fiduciary or confidential relationship, one of the elements generally considered in determining the appropriateness of imposing a constructive trust.
In sum, the constructive trust is a remedy that may be applied in a variety of situations where equity demands, despite the feasibility of strictly satisfying its elements, and should be kept in mind as a potential claim to correct a wrong that may not fit squarely within any other cause of action.
