Florida Prenuptial Agreement Attorney

Quick Answer

Do you need a lawyer for a prenuptial agreement in Florida?

Not legally, but it is strongly advised. Florida enforces prenuptial agreements under Fla. Stat. § 61.079 only if the agreement is in writing, signed voluntarily by both parties, and supported by fair and reasonable financial disclosure. Notarization is not required. Because a court can set aside an agreement that is unconscionable or signed without adequate disclosure, most couples — at every income level — have each side review the agreement with their own attorney so it holds up years later.

A well-drafted prenuptial agreement lets you decide, in advance and on your own terms, how property, debt, and support will be handled if a Florida marriage ends. Pazos Law Group drafts, reviews, and enforces prenups under Fla. Stat. § 61.079 for clients across Miami-Dade, Broward, and Palm Beach counties — in English and Spanish. Whether you need a Florida prenup lawyer to draft a new agreement or to review one your fiancé(e) presented, we make the process clear and low-stress.

Who a Florida Prenup Is For

A prenuptial agreement is no longer just for the wealthy. Today, couples of every income level use one to begin marriage with a clear, shared financial plan. Wherever you fall below, the goal is the same — certainty the two of you agree on, instead of Florida’s default rules under Fla. Stat. § 61.075 deciding for you.

What a Prenuptial Agreement Is — and Why People Use One

A prenuptial agreement — also called a “prenup” or premarital agreement — is a written contract entered into by two people before they marry. Under Florida’s Uniform Premarital Agreement Act, codified at Fla. Stat. § 61.079, the agreement becomes effective upon the marriage. It allows the couple to define their own financial rules rather than relying entirely on Florida’s default equitable-distribution and alimony statutes if the marriage later ends in divorce or death.

Prenups are not only for the wealthy. They are practical planning tools whenever one or both partners bring meaningful assets, obligations, or expectations into a marriage. Common reasons Florida couples ask us to prepare a prenup include:

Asset protection. Keeping premarital savings, real estate, retirement accounts, and investments classified as separate, non-marital property.
Business owners and professionals. Shielding a company, professional practice, partnership interest, or future earning capacity from division or valuation disputes in a divorce.
Second marriages. Protecting assets accumulated before the new marriage and preserving arrangements made after a prior divorce.
Blended families. Making sure children from a prior relationship inherit as intended and that a surviving spouse’s rights are clearly defined.
Inheritances and family wealth. Confirming that gifts, inheritances, and family-business interests stay with the spouse who received them.
Debt clarity. Establishing that student loans, business debt, or credit obligations one party brings in remain that party’s responsibility.

A prenup also reduces uncertainty. Instead of leaving critical questions to be litigated years later under stress, the couple sets clear, enforceable expectations at the outset. That predictability is often the single most valuable feature of a well-prepared agreement.

The 5 Requirements to Make a Florida Prenup Enforceable

Florida courts will enforce a prenuptial agreement that is properly prepared, but a poorly drafted one can be set aside at exactly the moment it matters most. Based on § 61.079 and how Florida courts apply it, a Florida prenup must:

Be in writing. Oral premarital agreements are not enforceable.
Be signed by both parties. Under § 61.079(3) the agreement is enforceable without consideration other than the marriage itself.
Be entered into voluntarily, without duress or coercion.
Be entered into with fair financial disclosure — or with a valid written waiver of disclosure.
Not be unconscionable at the time of execution.

These five points are the practical core. The statute frames the flip side in § 61.079(7)(a): an agreement is not enforceable if the party challenging it proves that (1) it was not executed voluntarily; (2) it was the product of fraud, duress, coercion, or overreaching; or (3) it was unconscionable when executed and, before signing, that party was not provided a fair and reasonable disclosure of the other party’s finances, did not expressly waive disclosure in writing, and could not reasonably have had adequate knowledge of those finances. Whether an agreement is unconscionable is decided by the court as a matter of law under § 61.079(7)(c). For a plain-language walk-through, see our guide to Fla. Stat. § 61.079.

What a Prenup Can Cover

Under § 61.079(4)(a), a Florida premarital agreement can address a wide range of financial and property matters, including:

The classification and division of property — whenever and wherever it was acquired — as marital or non-marital.
The disposition of property on divorce, separation, or death.
Spousal support: establishing, modifying, waiving, or eliminating alimony.
The treatment of business interests, professional practices, and inheritances.
The making of wills, trusts, or other estate-planning arrangements to carry out the agreement.
The ownership and disposition of life-insurance death benefits.
The choice of which state’s law governs the agreement and the forum for resolving disputes.

What a Prenup Cannot Do

There are firm limits. Under § 61.079(4)(b), a prenuptial agreement cannot adversely affect a child’s right to support, and it cannot predetermine child custody, time-sharing, or parental responsibility. Those issues are decided under the best-interests standard of § 61.13 when the question actually arises — not years earlier by contract. A separate statutory guardrail in § 61.079(7)(b) provides that if a support provision would leave one spouse eligible for public assistance at separation or divorce, a court may order enough support to avoid that outcome despite the agreement.

Financial Disclosure and Independent Counsel

Two best practices do more than anything else to keep a prenup enforceable, even though the statute does not strictly require either one.

Fair financial disclosure. Each party should exchange a complete, written schedule of assets, debts, income, and interests, attached as exhibits to the agreement. When disclosure is full and documented, a later claim of “I didn’t know what I was giving up” is far harder to sustain. If a party chooses to waive disclosure, that waiver must be express and in writing to satisfy § 61.079(7)(a).

Independent counsel. Florida law does not require each spouse to have a separate lawyer, but separate representation is the strongest available evidence that both parties signed voluntarily and understood the agreement. When one side has counsel and the other does not, the risk of a later voluntariness or overreaching challenge rises. We routinely encourage the other party to obtain their own attorney precisely because it makes the finished agreement more durable.

Drafting a Prenup vs. Reviewing One You Were Given

Prenup work comes in two forms, and Pazos Law Group handles both.

Drafting. If you are the party initiating the agreement, we build it from your goals up: identifying and classifying assets, structuring property and support terms, preparing disclosure schedules, and drafting clean, specific language that anticipates foreseeable contingencies. Careful drafting is what makes an agreement both fair on its face and defensible later.

Reviewing. If your fiancé presented you with a proposed agreement, do not sign it without independent review. We explain exactly what you would be giving up, flag one-sided or unconscionable terms, verify that disclosure is adequate, and negotiate revisions before anything is signed. A focused review often surfaces issues that would otherwise surface only in a divorce.

Timing: Start Well Before the Wedding

There is no statutory minimum waiting period, but timing is one of the factors a court weighs when deciding whether an agreement was signed voluntarily. An agreement negotiated over several weeks, with time for each party to review it with independent counsel, supports enforceability. An agreement pushed across the table the night before the ceremony — when one party feels they cannot say no — invites a duress or overreaching challenge under § 61.079(7)(a). As a practical rule, begin the conversation as early as possible and aim to have the agreement signed well before the wedding, not in its final days. Amending or revoking a prenup later is possible, but only by a written agreement signed by both parties under § 61.079(6).

How a Florida Prenup Lawyer Helps

Our family-law practice focuses on the financial architecture of marriage and divorce, which is exactly what a prenup governs. We help clients:

Clarify goals — asset protection, business continuity, estate planning, or support terms — and translate them into enforceable provisions.
Prepare complete financial disclosure schedules that hold up to scrutiny.
Draft or review agreements with clear definitions and carefully structured property and support terms.
Coordinate with the other party’s counsel and negotiate revisions.
Advise on how a prenup interacts with equitable distribution — you can model outcomes with our Florida Marital Asset Division Calculator.
Enforce or challenge existing agreements when a marriage ends.

We work in English and Spanish and offer a confidential consultation to discuss your situation and the right approach. Every engagement is different, and the enforceability of any agreement depends on its specific facts and drafting — there are no guaranteed outcomes, but sound preparation meaningfully improves the odds that an agreement will hold.

Already Married? Consider a Postnuptial Agreement

If the wedding has already happened, the equivalent instrument is a postnuptial agreement. It does similar work, but it is not governed by § 61.079 — Florida enforces postnups under common law and Casto v. Casto, 508 So. 2d 330 (Fla. 1987). See our Florida postnuptial agreement attorney page.

How the Prenup Process Works

A prenup should feel calm and collaborative, not adversarial. Our process is built to be clear and low-stress, and most couples complete it comfortably in about two to three weeks when they begin early.

Confidential consultation

We learn your situation and goals and explain how Florida law would treat your finances without an agreement.

Share your details

A simple, guided checklist captures each partner’s assets, debts, and income — the fair disclosure the law requires.

Draft & review together

We prepare a clear agreement, walk you both through every term, and refine it until it fits.

Sign with confidence

With time before the wedding for independent review, you both sign a well-documented, enforceable agreement.

Because Florida courts weigh whether an agreement was signed voluntarily and without time pressure under Fla. Stat. § 61.079, starting well before the wedding is the single best thing you can do to keep your prenup strong. Not sure where to begin?

Frequently Asked Questions

Does a Florida prenup have to be notarized?

No. Under Fla. Stat. § 61.079(3), a Florida premarital agreement only needs to be in writing and signed by both parties, and it is enforceable without any consideration other than the marriage itself. Notarization and witnesses are not required by statute. Many attorneys still notarize prenups as an optional best practice to help authenticate signatures, but the absence of a notary does not make the agreement invalid.

Are prenuptial agreements enforceable in Florida?

Yes. Florida adopted the Uniform Premarital Agreement Act (Fla. Stat. § 61.079). To be enforceable, the agreement must be in writing, signed by both parties, entered into voluntarily, with fair financial disclosure (or a valid written waiver), and not unconscionable at the time of execution. The agreement takes effect upon marriage.

Can a Florida prenup waive alimony?

Yes. Under § 61.079(4)(a), a prenup can establish, modify, waive, or eliminate spousal support. One limit applies: under § 61.079(7)(b), if a spousal-support provision would cause one party to qualify for public assistance at the time of separation or divorce, a court may order enough support to avoid that eligibility, notwithstanding the agreement.

Can a prenup decide child custody or child support in Florida?

No. Under § 61.079(4)(b), a premarital agreement cannot adversely affect a child’s right to support and cannot predetermine time-sharing or parental responsibility. Those issues are decided under the best-interests standard of § 61.13 when the question actually arises.

How can a Florida prenup be challenged or set aside?

Under § 61.079(7)(a), a prenup is not enforceable if the party opposing it proves that it was not executed voluntarily; that it was the product of fraud, duress, coercion, or overreaching; or that it was unconscionable when executed and, before signing, that party was not given fair and reasonable financial disclosure, did not waive disclosure in writing, and could not reasonably have had adequate knowledge of the other party’s finances. Unconscionability is decided by the court as a matter of law.

How is a postnuptial agreement different from a prenup in Florida?

A prenuptial agreement is signed before marriage and takes effect at the wedding; a postnuptial agreement is signed after the marriage has begun. Florida has no specific postnup statute, so courts apply general contract principles with heightened scrutiny because spouses owe each other a fiduciary duty. The same core elements still apply: writing, voluntary execution, fair disclosure, and absence of unconscionability. Learn more on our Prenuptial & Postnuptial Agreements hub.
