Yes, prenuptial agreements are legally enforceable in Rhode Island when they meet the requirements of the Rhode Island Uniform Premarital Agreement Act. The agreement must be in writing, signed voluntarily by both parties, accompanied by full financial disclosure, and not unconscionable at the time it was signed. A court can invalidate a prenup if it was signed under duress, if financial information was concealed, or if the terms are grossly unfair to one party.
