Waiving Financial Disclosure in a Florida Prenup: Fla. Stat. § 61.079(7)(a)3 (2026)

By Nadia Pazos, Family Law Attorney, Pazos Law Group · Updated October 2026

Quick Answer

Can a prenup be thrown out because one side did not disclose everything? Not on that fact alone. Under Fla. Stat. § 61.079(7)(a)3., the challenger must prove the agreement “was unconscionable when it was executed” and that, before signing, they (a) were not given fair and reasonable disclosure, (b) did not “voluntarily and expressly waive, in writing,” disclosure beyond what was provided, and (c) did not have, and could not reasonably have had, adequate knowledge of the other party’s finances. The three conditions are joined by “and,” so a valid written waiver defeats this ground. It does not defeat the separate grounds of involuntary signing or fraud, duress, coercion or overreaching in (7)(a)1.–2.

§ 61.079(7)(a) — Exact Text

“(a) A premarital agreement is not enforceable in an action proceeding under the Florida Family Law Rules of Procedure if the party against whom enforcement is sought proves that:
1. The party did not execute the agreement voluntarily;
2. The agreement was the product of fraud, duress, coercion, or overreaching; or
3. The agreement was unconscionable when it was executed and, before execution of the agreement, that party:
a. Was not provided a fair and reasonable disclosure of the property or financial obligations of the other party;
b. Did not voluntarily and expressly waive, in writing, any right to disclosure of the property or financial obligations of the other party beyond the disclosure provided; and
c. Did not have, or reasonably could not have had, an adequate knowledge of the property or financial obligations of the other party.”

Source: Fla. Stat. § 61.079 (Florida Senate). Subsection (7)(c) adds: “An issue of unconscionability of a premarital agreement shall be decided by the court as a matter of law.”

How the Three Conditions Work Together

Ground 3 has two layers. First, the agreement must have been unconscionable when signed — a question the judge decides as a matter of law under (7)(c). Second, all three disclosure conditions must be true. If any one of them is missing, ground 3 fails:

The burden is on “the party against whom enforcement is sought” — the person trying to get out of the agreement.

What the Waiver Covers, and What It Does Not

The waiver in (7)(a)3.b. is of disclosure “beyond the disclosure provided.” It is not a waiver of everything. Three practical points follow from the text:

Frequently Asked Questions

Can a Florida prenup be set aside for lack of financial disclosure?

Only under § 61.079(7)(a)3., which also requires that the agreement was unconscionable when signed, that the challenger did not waive further disclosure in writing, and that they lacked adequate knowledge of the other party’s finances.

Is a written disclosure waiver enough to make a prenup enforceable?

No. It defeats the disclosure ground in (7)(a)3., but the agreement can still be challenged as involuntary or as the product of fraud, duress, coercion or overreaching under (7)(a)1.–2.

Who decides whether a prenup is unconscionable?

The judge. § 61.079(7)(c) says unconscionability “shall be decided by the court as a matter of law.”

Should I sign a disclosure waiver my fiancé’s lawyer drafted?

Have your own lawyer read it first, together with whatever has been disclosed. Pazos Law Group reviews prenup drafts and waivers for clients in Miami-Dade, Broward and Palm Beach counties, in English or Spanish: (305) 482-1262. See our prenup review attorney page.
