New York Postnuptial Agreement Overview
New York recognizes postnuptial agreements under Domestic Relations Law Section 236(B)(3), which specifically authorizes agreements between spouses or prospective spouses that modify property rights. New York has well-developed case law on postnuptial agreements, and the state's courts have generally been supportive of such agreements when properly executed.
New York is an equitable distribution state under DRL Section 236(B)(5), where marital property is divided equitably considering thirteen statutory factors. New York's high cost of living, significant real estate values, and concentration of high-net-worth individuals make postnuptial agreements particularly common and important.
New York requires postnuptial agreements to be in writing, signed, and acknowledged (notarized) in the same manner as a deed. This formal requirement under DRL 236(B)(3) provides a clear standard for execution. New York courts apply the fiduciary duty standard and examine whether the agreement was fair, voluntary, and supported by full financial disclosure.

Important: New York Execution Requirements
New York requires postnuptial agreements to be in writing, signed, and acknowledged (notarized) in the manner required for recording a deed (DRL 236(B)(3)). Both spouses should have independent counsel. Full financial disclosure is essential. Given New York's high asset values and complex financial situations, thorough drafting is critical.

- Voluntary Execution: Both spouses must sign voluntarily without duress, coercion, or undue influence
- Full Financial Disclosure: Both spouses must provide complete and accurate disclosure of all assets, debts, income, and financial obligations
- Not Unconscionable: The agreement must not be so one-sided as to be unconscionable under New York law
What Can Be Addressed

- Disposition of property upon separation, divorce, or death
- Spousal support (alimony) terms, modifications, or waivers
- Life insurance, estate planning, and inheritance provisions
