Prenup Agreement in Florida: Requirements, Validity, Enforceability & Planning

If you are planning to marry in Florida and want to protect assets, a business, or family expectations, a prenup agreement in Florida (a premarital agreement) can set clear rules in advance. This guide explains what Florida law says, what a prenup can and cannot cover, how enforceability works, and how to prepare. It is general information, not legal advice, and does not create an attorney-client relationship.

What Is a Prenup Agreement in Florida?

A prenuptial agreement is a written contract between two people who plan to marry. It takes effect on marriage and lets the couple decide, by contract, how certain property and financial rights will be handled during the marriage, at divorce, or at death. Florida has adopted the Uniform Premarital Agreement Act, codified at section 61.079, Florida Statutes.

A prenup does not replace a will, trust, or estate plan. It works alongside them, and the documents should be coordinated.

Core Florida Requirements

Under section 61.079, a premarital agreement must be in writing and signed by both parties. It requires no consideration other than the marriage itself, and it becomes effective only upon marriage. Section 61.079 applies to premarital agreements made in contemplation of marriage; an agreement made after marriage is a postnuptial agreement and should be analyzed separately under applicable Florida law. Section 61.079 also addresses amendment or revocation after marriage, which requires a signed written agreement.

The Uniform Premarital Agreement Act applies to premarital agreements executed on or after October 1, 2007. Agreements executed before that date may be governed by different legal standards and should be evaluated separately.

What a Prenup Can Address

Under the statute, parties may contract about matters including:

• Rights and obligations in each party's property, whenever and wherever acquired
• The right to buy, sell, use, transfer, manage, or control property
• How property is divided on separation, divorce, death, or another event
• Spousal support (alimony), subject to limits discussed below
• Making a will, trust, or other arrangement to carry out the agreement
• Death benefit elections under life insurance
• Choice of law governing the agreement
• Any other matter that does not violate public policy or criminal law

Common practical uses include protecting premarital assets, defining separate versus marital property, protecting a family or closely held business, and addressing debts or inheritances.

Agreements addressing inheritance rights, elective-share waivers, or other rights arising at death must also be evaluated under Florida's applicable probate statutes, including sections 732.701 and 732.702, Florida Statutes. A prenup should be coordinated with the parties' estate-planning documents rather than treated as a substitute for them.

What a Prenup Cannot Do

The statute states that a premarital agreement cannot adversely affect a child's right to support. Provisions concerning parental responsibility and time-sharing are subject to the court's determination of the child's best interests and cannot conclusively control those decisions.

Also, if a spousal-support provision modifies or eliminates support and that change causes a party to become eligible for support under a public-assistance program at the time of separation or marital dissolution, a court may require the other party to provide support to the extent necessary to avoid that eligibility.

When a Florida Prenup May Not Be Enforced

A party challenging a prenup generally must prove one of the grounds in section 61.079(7). In summary, enforcement may be refused if the party did not sign voluntarily, or if the agreement was the product of fraud, duress, coercion, or overreaching. Enforcement may also be refused if the agreement was unconscionable when executed and the challenging party was not given fair and reasonable disclosure of the other party's property and obligations, did not voluntarily and expressly waive disclosure in writing, and did not have, or reasonably could not have had, adequate knowledge of that information.

Florida courts also look at whether there was fraud, concealment, or lack of full disclosure, so the quality of the process matters as much as the wording.

Practical Steps to a Stronger Prenup

• Start early. Begin negotiations well before the wedding. Florida law does not impose a fixed waiting period, but last-minute pressure, inadequate time for review, or coercive circumstances may become relevant in a later enforceability dispute.
• Exchange full financial disclosure. List assets, debts, income, and business interests, and attach schedules.
• Use separate counsel. Although Florida law does not require each party to retain separate counsel, independent legal representation is strongly recommended. It helps each party understand the agreement and may provide useful evidence of an informed, voluntary decision.
• Be specific. Define separate property, appreciation, commingling, and treatment of a business.
• Plan for change. Address children, relocation, and income changes, and consider review points.
• Coordinate estate planning. Align beneficiary designations, wills, and trusts.

Business Owners and International Couples

If one spouse owns or plans to start a company, a prenup can address ownership, valuation method, and treatment of growth during the marriage. See Protecting a Business Before Marriage for planning considerations. International couples, or those with assets abroad, should also consider choice of law, foreign property, and immigration or tax consequences, which require individual advice.

Frequently Asked Questions

Do I need a lawyer to make a prenup in Florida?

The statute does not require each party to have an attorney, but independent legal representation is strongly recommended. Separate counsel can help both parties understand their rights, evaluate financial disclosures, negotiate appropriate terms, and reduce the risk of a later challenge to the agreement.

Can a prenup be changed after the wedding?

Section 61.079 provides that after marriage, a premarital agreement may be amended or revoked only by a written agreement signed by the parties.

Do both spouses have to disclose finances?

Fair and reasonable disclosure, or a voluntary written waiver of disclosure, is central to enforceability. Full disclosure is the safer approach.

Does a prenup control child support or custody?

No. A prenup cannot adversely affect a child's right to support. Decisions concerning parental responsibility and time-sharing remain subject to the child's best interests and applicable Florida law.
