What Is a Postnuptial Agreement?

A postnuptial agreement is a legally binding contract signed by spouses after marriage that establishes how assets, debts, and financial matters will be handled. Unlike prenuptial agreements signed before marriage, postnuptial agreements address circumstances that arise during the marriage, such as career changes, inheritances, business start-ups, or reconciliation after separation.

Postnuptial agreements can provide financial clarity, protect separate property, establish business ownership terms, and prevent costly divorce litigation. They require full financial disclosure, voluntary consent, and ideally independent legal representation for both spouses to ensure enforceability.

Postnuptial Agreement Cost Formula

Total Cost = (Attorney Hourly Rate × Estimated Hours × Complexity Multiplier) + Mediation Cost + Filing Fees

Complexity multipliers: Simple = 1.0, Moderate = 1.5, Complex = 2.5

Postnuptial agreements often involve additional considerations compared to prenuptial agreements, including mediation to facilitate discussions between spouses who are already married and may have established financial patterns.
