What is the definition of a Prenuptial Agreement?

A prenuptial agreement is a written contract signed before marriage that decides how property, debts, and support will be handled if the marriage ends or a spouse dies. It lets the couple, not Florida’s default rules, control the financial outcome.

What a Prenuptial Agreement Can Cover in Florida

Under Florida’s Uniform Premarital Agreement Act, the couple may agree on:

A prenup cannot pre-determine child support or waive a child’s right to support, and it cannot override the court’s best interests standard for time-sharing.

Requirements for a Valid Prenuptial Agreement

Florida Statute 61.082 sets three basics. The agreement must be in writing, signed by both parties, and no payment or exchange is required to make it binding. It takes effect at marriage. In practice, courts also look for full financial disclosure and honest, voluntary signing when the agreement is later challenged.

When a Prenuptial Agreement Can Be Thrown Out

Florida Statute 61.086 allows a court to set a prenup aside when a spouse signed it involuntarily, or when it is unconscionable and that spouse was never given fair financial disclosure. Pressure at the eleventh hour and hidden assets are the usual reasons agreements fail.

Prenuptial vs. Postnuptial Agreements

The difference is timing. A prenup is signed before the wedding; a postnuptial agreement is signed after the marriage has already begun. Florida law treats both as valid contracts, but postnups face heavier scrutiny because spouses owe each other fiduciary duties once married.
