Postnuptial Agreement

In New York State, a postnuptial agreement is a marital agreement entered into after marriage in which spouses outline how they will manage property, finances, and support matters during the marriage and in the event of divorce or death. Although New York’s statutes do not explicitly use the term “postnuptial,” Domestic Relations Law § 236(B)(3) stipulates that an agreement “made before or during the marriage” is valid and enforceable if it is in writing, signed by both parties, and acknowledged or proven in the manner required for a deed to be recorded. This statutory language has been interpreted by New York courts to encompass agreements entered into after the wedding, rendering postnuptial agreements enforceable as long as they adhere to the same formal requirements as prenuptial agreements.

To be enforceable under New York law, a postnuptial agreement must fulfill several crucial legal prerequisites. It must be in writing and signed by both spouses, with signatures acknowledged before a notary public to satisfy the deed-recording requirement of DRL § 236(B)(3). Courts also mandate full and equitable financial disclosure by both spouses at the time of execution, and that the agreement was entered into voluntarily without fraud, duress, or coercion. If an agreement is unconscionable, excessively one-sided, or violates public policy, a court may refuse to enforce it. While New York does not mandate that each spouse be separately represented by counsel, judicial scrutiny is heightened where one spouse lacks independent legal advice.

The primary objective of a postnuptial agreement is to grant married couples control over financial matters that would otherwise be subject to default state law in divorce or upon the death of a spouse. Couples frequently utilize postnuptial agreements if someone is unfaithful, deceitful, manipulative to clarify property rights including the distinction between separate and marital property; to address spousal maintenance (alimony) terms; or to safeguard business interests, inheritances, or intricate assets that might otherwise be classified as marital property. Additionally, they are employed to establish custody and parenting time arrangements and associated child support provisions. These agreements can mitigate uncertainty, minimize litigation, and provide both spouses with clear expectations regarding financial responsibilities and outcomes.
