A prenuptial agreement in Florida is a legally binding contract created by two individuals before marriage to outline the division of assets, debts, and financial responsibilities in the event of divorce or death. Governed by the Florida Uniform Premarital Agreement Act, it allows couples to protect separate property, clarify financial expectations, and avoid potential disputes. The agreement must be in writing and signed voluntarily by both parties, with full disclosure of assets and liabilities. Courts may enforce it unless it is proven to be fraudulent, coerced, or unconscionable at the time of execution or enforcement under applicable Florida law.
