New Hampshire Postnuptial Agreement Overview
New Hampshire recognizes postnuptial agreements under general contract law principles and the fiduciary duty framework between spouses. New Hampshire courts have upheld agreements between married parties when they meet the requirements for voluntariness, fairness, and full disclosure.
New Hampshire is an equitable distribution state under RSA 458:16-a, where marital property is divided equitably. A postnuptial agreement allows New Hampshire couples to define property division terms rather than relying on judicial discretion.
New Hampshire courts apply heightened scrutiny to postnuptial agreements due to the fiduciary relationship between spouses. Both parties should have independent counsel, and complete financial disclosure is essential.
