What Can a Florida Prenup Include? — § 61.079(4)
Florida’s prenup statute gives couples broad freedom to structure their financial relationship before marriage — but not unlimited freedom. Here is exactly what § 61.079(4) permits, what it prohibits, and where the line is.
Quick Answer
Fla. Stat. § 61.079(4)(a) lists eight categories of permitted subjects for a Florida prenup, including property rights, spousal support, wills, life insurance benefits, and choice of law. The one hard limit: § 61.079(4)(b) provides that a child’s right to support may not be adversely affected by a premarital agreement.
The One Hard Limit: Child Support — § 61.079(4)(b)
Fla. Stat. § 61.079(4)(b) states plainly: “The right of a child to support may not be adversely affected by a premarital agreement.” This means:
- A prenup cannot waive, reduce, or cap child support.
- Child support is calculated under the § 61.30 guidelines at the time of dissolution, regardless of what the agreement says.
- A prenup cannot predetermine a parenting plan or time-sharing schedule. Custody is governed by the best-interests standard in § 61.13(2)(c)1.
Any provision that attempts to limit child support is unenforceable on its face. The rest of the agreement remains valid — the offending provision is severed, not the entire contract.
“The right of a child to support may not be adversely affected by a premarital agreement.” — Fla. Stat. § 61.079(4)(b)
Alimony Waivers After the 2023 Reform
§ 61.079(4)(a)4. expressly permits the “establishment, modification, waiver, or elimination of spousal support.” Since the 2023 reform of § 61.08 (SB 1416, effective July 1, 2023), permanent alimony no longer exists in Florida. The forms a prenup can now address are bridge-the-gap, rehabilitative, and durational alimony. A complete alimony waiver remains permissible, subject to the unconscionability analysis under § 61.079(7)(a)3. and the public-assistance safety valve in § 61.079(7)(b).
Overriding Equitable Distribution — § 61.075(6)(b)
One of the most powerful effects of a prenup is its interaction with Fla. Stat. § 61.075 (equitable distribution). Under § 61.075(6)(b), assets and liabilities excluded from marital property by a valid written agreement are nonmarital and therefore outside the court’s equitable distribution. In other words, a prenup lets couples opt out of Florida’s default property-division rules entirely or selectively.
What About “Lifestyle” Clauses?
The catch-all in § 61.079(4)(a)8. (“any other matter not in violation of law or public policy”) has been used to include provisions on topics such as:
- Dispute resolution (mediation or arbitration before litigation)
- Pet ownership and care
- Social media privacy provisions
- Infidelity consequences (enforceable in some jurisdictions, but Florida courts have not squarely ruled on “infidelity penalty” clauses; enforceability is uncertain)
The safer approach is to focus on the eight enumerated categories and use the catch-all sparingly for provisions that clearly do not violate public policy.
Frequently Asked Questions
Can a Florida prenup waive alimony completely?
Yes. § 61.079(4)(a)4. expressly permits the waiver or elimination of spousal support. The waiver is enforceable unless the agreement is unconscionable under § 61.079(7)(a)3. or would leave the other party eligible for public assistance under § 61.079(7)(b).
Can a prenup determine child custody in Florida?
No. § 61.079(4)(b) prohibits adversely affecting a child's right to support, and custody/time-sharing is determined under the best-interests standard in § 61.13 at the time of dissolution.
Can a prenup protect a business I own before marriage?
Yes. Under § 61.079(4)(a)1., the parties can classify a pre-owned business as nonmarital property. Combined with § 61.075(6)(b), this removes the business from equitable distribution. The appreciation during marriage may still need to be addressed in the agreement.
Can a prenup include an infidelity clause in Florida?
The catch-all provision in § 61.079(4)(a)8. permits “any other matter not in violation of law or public policy.” Florida courts have not squarely ruled on infidelity penalty clauses. They may be included, but enforceability is not guaranteed.
