Key takeaways

  • Prenups are legal and enforceable in Florida under the Uniform Premarital Agreement Act, Fla. Stat. § 61.079 (adopted 2007).
  • Florida adds extra defenses to the standard UPAA list: a prenup fails if it was the product of fraud, duress, coercion, or overreaching.
  • Signing before a notary and two witnesses matters in Florida — waiving estate and homestead rights requires two subscribing witnesses under Fla. Stat. § 732.702.
  • Alimony can be waived in a Florida prenup, but temporary support and attorney's fees during the divorce case itself cannot (Belcher v. Belcher).
  • Florida is an equitable-distribution state, so a prenup is how couples decide in advance what stays separate.

Are prenups legal in Florida?

Yes — prenuptial agreements are legal and enforceable in Florida under Fla. Stat. § 61.079, the state's version of the Uniform Premarital Agreement Act.

Florida adopted the Uniform Premarital Agreement Act effective October 1, 2007, codified at Fla. Stat. § 61.079. The agreement must be in writing and signed by both parties, is enforceable without consideration, and takes effect on marriage. Florida's version is slightly tougher on bad behavior than the model act: § 61.079(7) lets a spouse challenge an agreement that was the product of fraud, duress, coercion, or overreaching — grounds Florida courts developed in pre-2007 case law like Casto v. Casto and carried into the statute. Agreements signed before October 2007 are still judged under that case law.

What makes a prenup enforceable in Florida?

A Florida prenup is enforceable when it is in writing, signed by both parties, entered voluntarily with fair financial disclosure, and free of fraud, duress, coercion, or overreaching.

In writing and signed

Fla. Stat. § 61.079(4) requires a written agreement signed by both parties. No consideration is needed — the marriage itself is enough.

Signed with witnesses and a notary

The base statute doesn't demand it, but waiving spousal estate and homestead rights — which nearly every real prenup does — requires two subscribing witnesses under Fla. Stat. § 732.702. Signing before a notary and two witnesses closes every formality gap at once.

Voluntary — no fraud, duress, coercion, or overreaching

Florida names these defenses explicitly in § 61.079(7)(a). A prenup presented for the first time days before a Florida wedding invites an overreaching claim; an early, unhurried signing defuses it.

Fair disclosure (or a valid written waiver)

An unconscionable agreement fails if the challenging spouse wasn't given fair and reasonable disclosure of property and debts, didn't waive disclosure in writing, and couldn't reasonably have known the other's finances.

What you can & can't include

You can include

  • Defining separate vs. marital property and future appreciation
  • How income and assets acquired during marriage are characterized
  • Responsibility for premarital and marital debt
  • Establishing, limiting, or waiving post-divorce alimony
  • Protecting a business, inheritance, or retirement accounts
  • Waiving elective-share and homestead rights on death (with proper witnessing)

You can't include

  • Child custody or timesharing arrangements
  • Child support (a child's right to support can't be adversely affected)
  • Waivers of temporary alimony or attorney's fees while a divorce is pending
  • Anything that violates public policy or criminal law

How Florida courts evaluate enforcement

Florida courts set aside prenups that were the product of fraud, duress, coercion, or overreaching, or that were unconscionable and signed without fair financial disclosure.

Fla. Stat. § 61.079(7) puts the burden on the spouse challenging the agreement, but Florida gives that spouse a longer menu of arguments than most UPAA states — overreaching in particular sweeps in one-sided bargaining tactics that fall short of outright duress. Florida courts also police one boundary no prenup can cross: under Belcher v. Belcher, a spouse cannot waive temporary support, temporary attorney's fees, or suit money while the divorce itself is pending, because that obligation belongs to the marriage, not the settlement. A fully disclosed, properly witnessed Florida prenup signed well before the wedding survives all of it.

Florida prenup FAQ

How much does a prenup cost in Florida?

A Florida attorney-drafted prenup commonly costs $2,500–$10,000+. Trusted Prenup creates a state-specific Florida prenup online for a flat $599, with online notarization and attorney review available as add-ons.

Does a Florida prenup need to be notarized?

Fla. Stat. § 61.079 itself only requires a signed writing — but waiving estate and homestead rights, which most prenups do, requires two subscribing witnesses under Fla. Stat. § 732.702. Your Trusted Prenup includes the witness attestation block, and we recommend adding online notarization at checkout as proof of authenticity.

Can a prenup be challenged in Florida?

Yes. Florida allows challenges for fraud, duress, coercion, or overreaching, and for unconscionability paired with a failure of financial disclosure. Full disclosure, proper witnessing, and an early signing are what make a Florida prenup hold.

Can alimony be waived in a Florida prenup?

Post-divorce alimony can be limited or fully waived. But under Belcher v. Belcher, temporary support and attorney's fees while the divorce is actually pending cannot be waived — Florida courts treat that as a duty of the marriage itself.

What is 'overreaching' in a Florida prenup challenge?

Overreaching means one party used their stronger position to obtain an unfair bargain — for example, springing a complex agreement on a fiancé days before the wedding with no chance to review it. It's a distinctly Florida ground for challenge, and the cure is simple: disclose fully and sign early.

Does a Florida prenup cover the house we buy together?

It can. Your agreement can say how a jointly purchased home, its mortgage, and its appreciation are treated at divorce or death. Florida's constitutional homestead protections add wrinkles for the marital home, which is exactly why the agreement should address it explicitly.

Is an online prenup valid in Florida?

Yes — Florida enforces properly executed prenuptial agreements regardless of how they were drafted. What matters is execution: a written agreement, voluntary signatures, full financial disclosure, and Florida's signing formalities. The full picture is in are online prenups legally binding.
