Can a postnuptial agreement be illusory if it allows unlimited lifetime gifts? Peirce v. Peirce Explained

The Utah Supreme Court’s decision in Peirce v. Peirce provides crucial guidance for practitioners drafting and interpreting postnuptial agreements. The case demonstrates how courts will imply terms to prevent promises from becoming illusory and unenforceable.

Background and Facts

Ted and Agnes Peirce executed a written postnuptial agreement in 1985 under which Ted promised to leave his estate to Agnes at his death. In exchange, Agnes gave all her paychecks to Ted, keeping only a small allowance. Less than two months before his death in 1993, Ted made four gratuitous conveyances of real property and stock to his nephew Robert Peirce and Robert’s wife Lisa. Agnes sued seeking a constructive trust, claiming these transfers violated Ted’s agreement.

Key Legal Issues

The central issue was whether the postnuptial agreement impliedly restricted Ted’s ability to make substantial lifetime gifts. The trial court concluded Ted was “legally entitled to make transfers of his property prior to his death” and denied the constructive trust claim. Agnes argued this interpretation rendered Ted’s promise illusory for lack of consideration.

Court’s Analysis and Holding

The Utah Supreme Court reversed, applying correctness review to the contract interpretation issue. The court reasoned that if Ted could freely dissipate his estate through lifetime gifts, his promise would be “performable at his own whim and caprice,” making it an illusory promise that provided no consideration. Since Agnes would have inherited Ted’s intestate estate anyway, the only meaningful consideration Ted could provide was forbearance from making substantial lifetime transfers. The court emphasized the fiduciary duty governing postnuptial agreements between spouses.

Practice Implications

This decision highlights the importance of express terms in marital agreements. Courts will imply restrictions to prevent promises from becoming illusory, but practitioners should draft clear provisions regarding lifetime gifts to avoid litigation. The ruling also reinforces that spouses owe each other heightened fiduciary duties in postnuptial agreements, requiring courts to scrutinize such agreements for potential abuse of trust.
