How Much Does a Prenup Cost in Florida?

“How much does a prenup cost in Florida?” is the question everyone asks — but the more useful one is what it protects, because that is what determines the value of the agreement. Here is how to think about both.

Which Florida Statute Governs Prenuptial Agreements? (§ 61.079, Uniform Premarital Agreement Act)

Florida prenuptial agreements are governed by Fla. Stat. § 61.079(3) and the rest of the Uniform Premarital Agreement Act. Every proposition below is tied to the pinpoint subsection that supports it. Links go to the official text published by the Florida Legislature.

• § 61.079(1) — adopts the Uniform Premarital Agreement Act and applies it to proceedings under the Florida Family Law Rules of Procedure.
• § 61.079(2)(a) — defines a premarital agreement as one between prospective spouses made in contemplation of marriage and effective upon marriage.
• § 61.079(3) — requires the agreement to be in writing and signed by both parties, and makes it enforceable without consideration other than the marriage itself.
• § 61.079(4)(a)1.–8. — lists the permitted subjects, including property rights, management and disposition of property, wills and trusts, life insurance death benefits, and choice of law.
• § 61.079(4)(a)4. — expressly permits the establishment, modification, waiver, or elimination of spousal support.
• § 61.079(4)(b) — provides that a child’s right to support may not be adversely affected by a premarital agreement.
• § 61.079(5) — makes the agreement effective upon marriage.
• § 61.079(6) — allows amendment, revocation, or abandonment after marriage only by a written agreement signed by the parties.
• § 61.079(7)(a)1. — ground to set aside: the party did not execute the agreement voluntarily.
• § 61.079(7)(a)2. — ground to set aside: fraud, duress, coercion, or overreaching.
• § 61.079(7)(a)3. — ground to set aside: unconscionable when executed, combined with the absence of fair and reasonable disclosure, no written waiver of disclosure, and no adequate knowledge of the other party’s finances.
• § 61.079(7)(b) — allows a court to order support notwithstanding a waiver where the waiver would make a party eligible for public assistance.
• § 61.079(7)(c) — makes unconscionability a question for the court to decide as a matter of law.
• § 61.079(8) — limits enforcement where the marriage is determined to be void.
• § 61.079(9) — tolls the statute of limitations on claims under the agreement during the marriage, while preserving laches and estoppel.
• § 61.079(10) — confirms the section does not alter the formalities of spousal agreements under §§ 732.701–732.702.
• § 61.075(6)(b) — makes assets and liabilities excluded by a valid written agreement nonmarital and therefore outside equitable distribution.
• § 61.08(1)(a) — identifies the forms of alimony an agreement can waive or modify.
• § 61.30(1)(a) — the child support guidelines remain presumptive regardless of what the agreement says.
• § 61.16 — governs attorney’s fees in litigation over the agreement.
• Casto v. Casto, 508 So. 2d 330 (Fla. 1987) — the Florida Supreme Court decision on setting aside marital agreements.
• § 61.021 — requires 6 months of Florida residency before the dissolution in which the agreement is enforced.
• § 61.052 — supplies the no-fault ground for the proceeding in which the agreement is applied.
• § 61.19 — bars entry of the final judgment incorporating the agreement until at least 20 days after filing, absent a showing that the delay would cause injustice.
• § 61.13(2)(c)1. — time-sharing is fixed by statute and by the child’s best interests; a premarital agreement cannot bind it.
• § 61.14 — support terms the agreement leaves open remain subject to modification under this section.

“A premarital agreement must be in writing and signed by both parties. It is enforceable without consideration other than the marriage itself.” — Fla. Stat. § 61.079(3)

“An issue of unconscionability of a premarital agreement shall be decided by the court as a matter of law.” — Fla. Stat. § 61.079(7)(c)

“The right of a child to support may not be adversely affected by a premarital agreement.” — Fla. Stat. § 61.079(4)(b)

Answers to the Questions the Statute Actually Decides

Does a Florida prenup have to be notarized under § 61.079(3)?

The statute requires only that the agreement be in writing and signed by both parties. It does not require notarization or witnesses, and it expressly makes the agreement enforceable without consideration other than the marriage itself. Notarization is nevertheless routine practice because it makes execution far easier to prove later.

What can invalidate a Florida prenuptial agreement?

§ 61.079(7)(a) supplies three grounds, and the burden is on the party attacking the agreement: involuntary execution; fraud, duress, coercion, or overreaching; or unconscionability at execution combined with the absence of fair and reasonable financial disclosure, no written waiver of disclosure, and no adequate independent knowledge of the other party’s finances.

Can a prenup waive child support?

No. § 61.079(4)(b) provides that a child’s right to support may not be adversely affected by a premarital agreement. Child support is calculated under the § 61.30(1)(a) guidelines regardless of what the parties agreed before marriage.

Who decides whether a prenup is unconscionable?

The judge, and as a matter of law — that is the express command of § 61.079(7)(c). Unconscionability alone is also not enough; it must be paired with the disclosure failures listed in § 61.079(7)(a)3.

Cost is usually the second question couples ask about a prenup, right after “do we even need one?” The honest answer is that a well-drafted Florida prenuptial agreement is inexpensive compared to what it protects — and dramatically cheaper than litigating those same questions during a divorce years later. Under Fla. Stat. § 61.079, Florida’s version of the Uniform Premarital Agreement Act, a valid prenup lets a couple decide these issues in advance rather than leaving them to a court.

What a Prenup Actually Protects

Before the number, understand the value. A well-drafted Florida prenuptial agreement can keep a business or professional practice — and its growth — out of a future dispute, confirm that a home you owned before marriage stays yours, protect an inheritance or trust interest, keep pre-marital retirement and savings separate, assign responsibility for debt, and set clear expectations about spousal support. Just as importantly, it replaces uncertainty with a plan the two of you made together, calmly, in advance. That is what you are really investing in.

Measured against that, cost is the smaller question. A prenup resolves for a few thousand dollars the same issues that can cost tens or hundreds of thousands to litigate in a contested divorce — privately, without a public valuation fight years later.

What Determines the Investment

Most Florida family-law attorneys draft prenups on either a flat fee or an hourly basis (Miami-Dade hourly rates typically run $250–$700). The final number is driven by a handful of factors:

• Complexity of the assets. A couple with salaries, a home, and retirement accounts is simpler — and cheaper — than a couple with a closely held business, real estate in multiple states, RSUs, or assets held in trust.
• Financial disclosure. A prenup requires fair and reasonable disclosure of each party’s property and debts. The more organized your financials are, the less attorney time is spent assembling them.
• Negotiation. If the terms are agreed and straightforward, drafting is quick. Heavily negotiated alimony waivers or business-protection clauses add time.
• Separate counsel. Independent counsel for each spouse is not legally required, but it strengthens the agreement and adds a second attorney’s fee.

To see how those four factors stack up in your own situation, run them through the Florida Prenup Cost Estimator — it returns a complexity tier and names each answer that pushed your fee up or down, without printing a figure we have not verified.

Typical Investment Ranges in 2026

Simple prenup: $3,000–$5,000

Two people with ordinary assets — income, a home, savings, retirement — who largely agree on the terms. This is the most common scenario and often handled on a flat fee.

Moderately complex: $5,000–$10,000

One or both partners bring a professional practice, a small business, significant premarital investments, or an expected inheritance, and the alimony and business-growth clauses require careful drafting.

High-complexity / high-net-worth: $10,000–$15,000+

Closely held companies requiring coordination with corporate or tax counsel, multi-jurisdiction real estate, trusts, or heavy negotiation between two represented parties. Even at the top of this range, the cost is a fraction of what a contested valuation fight would cost in a later divorce.

Prenuptial Agreements for High-Net-Worth Couples

For couples with substantial or complex estates, the value of a prenup is not measured in the drafting fee — it is measured against the eight- or nine-figure questions it takes off the table. A well-structured agreement can shield a closely held business and its future growth, keep an anticipated inheritance and trust distributions non-marital, address equity compensation and carried interest, coordinate with an existing estate plan, and select governing law for holdings that cross state and national lines. Here, the prenup is drafted in concert with your wealth advisors, corporate counsel, and CPA, and handled with the discretion these matters require. The goal is not to spend less — it is to protect precisely what matters, cleanly and privately, before it is ever entangled.

Why Significant Assets Should Never Rely on a Template

A fill-in-the-blank template may be adequate for the simplest situations, but when a business, a professional practice, real estate, or family wealth is involved, a generic form is a false economy. A Florida prenup that fails one of the requirements in § 61.079 can be set aside entirely — usually during a divorce, after you have relied on it for years. The most common failure points are incomplete financial disclosure, language a Florida court reads as unconscionable, and signing under time pressure that undermines voluntariness. An agreement that protects a meaningful estate is drafted deliberately, with the disclosures and structure that make it hold up.

Drafting vs. Reviewing an Agreement

There are two different (and differently priced) services. Drafting is preparing the agreement from scratch, which matters most when you are the party bringing assets to protect. Review is having an attorney examine an agreement your fiancé(e)’s lawyer prepared, confirm the disclosures are complete, and advise you before you sign — typically a smaller, often flat, fee. Our Florida prenup checklist lists what to gather before either conversation, which keeps billable time down.

How to Make the Process Efficient

• Come organized. A complete list of assets, debts, and income up front lets your attorney focus time on structure and protection rather than data-gathering.
• Agree on the big terms first. Deciding the core points as a couple before drafting keeps the process smooth and amicable.
• Start early. Signing well before the wedding gives room for full disclosure and independent review, and supports the voluntariness requirement.
• Understand the default first. Our marital asset division calculator shows how Florida would divide assets without an agreement, which focuses the conversation on what actually needs protecting.

Whether the estate is modest or substantial, a prenuptial agreement is a small, deliberate investment in certainty. A consultation is the fastest way to get a firm quote tailored to your situation.
