Florida Prenuptial Agreement Statute: A Section-by-Section Guide to Fla. Stat. § 61.079

Overview: Florida's Premarital Agreement Statute

Florida adopted its version of the Uniform Premarital Agreement Act (UPAA) in 2007, codifying it as Florida Statute § 61.079. Before this enactment, Florida courts evaluated prenuptial agreements under a body of common law that had developed over decades, most notably through the Florida Supreme Court's decision in Posner v. Posner, 233 So. 2d 381 (Fla. 1970), which was among the first appellate decisions in the country to recognize the enforceability of prenuptial agreements addressing property division upon divorce.

The statute brought uniformity and predictability. It provides a clear framework that tells couples what a prenup can cover, what formalities it must satisfy, and on what grounds a court can refuse to enforce it. Florida was not the first state to adopt the UPAA, but its version contains several Florida-specific provisions—particularly regarding spousal support waivers under subsection (5)—that practitioners must understand.

The practical effect of § 61.079 is that Florida courts now apply a statutory test rather than a purely common-law analysis when deciding whether to enforce a premarital agreement. This gives both drafting attorneys and litigators a specific checklist of requirements and defenses to work through.

§ 61.079(2): Definitions

Plain-English Explanation

The definitions section establishes the statute's reach. "Premarital agreement" means exactly what it sounds like: a contract between two people who plan to marry, which takes effect when they do. The definition of "property" is deliberately expansive. It covers everything from real estate and bank accounts to business interests, retirement benefits, stock options, and future earnings. This breadth matters because it determines what assets the agreement can allocate between spouses.

Practical Implications

Because the statute defines property to include contingent interests and future income, a well-drafted prenup can address assets that do not yet exist at the time of signing. A spouse who expects to receive an inheritance, launch a business, or vest in stock options can include those interests in the agreement. Conversely, if the agreement fails to address a category of property, a court applying equitable distribution principles under § 61.075 will decide how to divide it.

§ 61.079(3): Formalities — Timing of the Agreement

Plain-English Explanation

The timing requirement is absolute. If the agreement is signed after the wedding ceremony, it is not a premarital agreement under § 61.079 and cannot be enforced under this statute. The agreement must be executed while both parties are still engaged—that is, before they become legally married.

Practical Implications

Timing creates one of the most common vulnerabilities in prenuptial agreements. An agreement signed the morning of the wedding, while technically "before" the marriage, may face a duress challenge under subsection (7) because one party had no meaningful opportunity to consult an attorney or negotiate terms. Florida courts have examined the circumstances surrounding the timing of execution when evaluating claims of duress or coercion.

§ 61.079(3): Form Requirements (continued)

Plain-English Explanation

Three rules emerge from this subsection. First, a prenup must be a written document—oral agreements about property division are not enforceable under this statute. Second, both prospective spouses must sign. Third, the agreement lies dormant until the couple marries; if the wedding is called off, the agreement has no legal effect. The statute also eliminates a traditional contract-law obstacle: there is no need for independent consideration (something of value exchanged). The mutual promises made in contemplation of marriage are sufficient.

Practical Implications

The writing requirement means that informal understandings, email exchanges, or verbal promises about "what happens if we divorce" carry no weight under § 61.079. Both parties must sign the same document. While the statute does not explicitly require notarization, having the signatures notarized adds an evidentiary layer of protection against later claims that a signature was forged or that the signing never occurred. Most experienced Florida family law attorneys treat notarization as a standard element of execution.

§ 61.079(4): Permitted Subjects

The statute permits the parties to contract regarding the following subjects:

1. Property Rights and Disposition

The agreement can define each party's rights and obligations in any property, wherever situated and whenever acquired. This includes the right to buy, sell, use, transfer, exchange, mortgage, or otherwise manage and control property. It can also govern how property is disposed of upon separation, marital dissolution, death, or any other event.

This is the core function of most prenuptial agreements. Couples use this provision to designate certain assets as separate property that will not be subject to equitable distribution in a divorce. Under Florida's equitable distribution statute, § 61.075, marital assets are divided equitably—which does not necessarily mean equally. A prenup allows parties to override that default regime with their own negotiated terms.

2. Spousal Support (Alimony)

The agreement may modify or eliminate spousal support obligations, subject to the important limitation in subsection (5) discussed below. Parties can set a specific alimony amount, establish a formula, or waive alimony entirely.

3. Life Insurance Benefits

The parties can make provisions regarding life insurance policy beneficiary designations and the disposition of death benefits. This is particularly significant for individuals entering second marriages who wish to preserve insurance benefits for children from a prior relationship.

4. Choice of Law

The agreement can specify which state's law governs its construction. This is valuable for couples who live in one state but plan to relocate, or who have assets in multiple states. Selecting Florida law ensures the agreement will be interpreted under § 61.079 regardless of where the couple eventually resides, though enforcement may ultimately be governed by the law of the state where divorce proceedings occur.

5. Wills, Trusts, and Estate Planning

The parties can agree to make, amend, or revoke wills or trusts to carry out the agreement's terms. This permits coordination between the prenuptial agreement and each party's estate plan, ensuring that the property allocations in the prenup are reflected in testamentary documents.

6. Death Benefit Rights

The agreement can address rights to death benefits from any source, including survivor benefits under pension plans and joint tenancy survivorship rights.

7. Personal Rights and Obligations

This provision allows the agreement to address personal (non-financial) rights and obligations, but with limits. Florida courts have declined to enforce provisions that touch on matters of public policy, such as child custody or child support, which are always subject to judicial determination based on the child's best interests.

8. Catch-All Provision

Any other matter not in violation of public policy or criminal law may be included. This gives couples flexibility to address unique circumstances, though it does not override statutory protections that cannot be waived by private agreement.

§ 61.079(7)(b): Spousal Support Limitation

Plain-English Explanation

This is an important safety valve. Even if both parties agreed to waive alimony entirely, a Florida court can override that waiver if enforcing it would leave one spouse so financially destitute that they would qualify for public assistance such as Medicaid or food stamps. The legislature determined that private agreements should not shift the cost of supporting a spouse onto taxpayers.

Practical Implications

Subsection (7)(b) operates as a floor, not a ceiling. A court applying this provision does not recalculate alimony from scratch under § 61.08. Instead, it provides only enough support to lift the disadvantaged spouse above the public-assistance threshold. The provision is measured at the time of separation or dissolution—not at the time the agreement was signed—which means a spouse's financial circumstances at the end of the marriage are what matter.

This provision comes into play most often in long marriages where one spouse left the workforce to raise children and has limited earning capacity at the time of divorce. If the prenup waived alimony entirely, that spouse can argue under subsection (7)(b) that enforcement of the waiver would leave them dependent on public assistance.

§ 61.079(6): Amendment and Revocation

Plain-English Explanation

Changing or canceling a prenup after the wedding requires the same formality as creating one: a written document signed by both spouses. One spouse cannot unilaterally modify or revoke the agreement, and oral modifications are not effective. As with the original agreement, no independent consideration is required—the spouses do not need to exchange anything of value to make the amendment binding.

Practical Implications

Couples whose financial circumstances change significantly during the marriage—through inheritance, career changes, or the birth of children—may wish to update their prenup. Subsection (6) permits this but requires both parties to agree in writing. A party who believes the original agreement is inadequate cannot force the other to accept modifications.

Any post-marriage amendment operates as a postnuptial agreement and should be treated with the same formality. Under the reasoning of Casto v. Casto, 508 So. 2d 330 (Fla. 1987), postnuptial modifications are subject to heightened scrutiny because the spousal relationship creates fiduciary obligations that do not exist between prospective spouses. Full financial disclosure at the time of modification is strongly advisable.

§ 61.079(7): Enforcement and Challenges

This is the most litigated section of § 61.079. Each ground for invalidation operates independently.

Ground 1: Involuntary Execution — § 61.079(7)(a)1

The first ground requires the challenging party to prove that they did not sign the agreement voluntarily. Florida courts assess voluntariness by examining the totality of the circumstances, including whether the party had adequate time to review the agreement, whether they had access to independent counsel, and whether they understood the terms.

Voluntariness is distinct from duress. A party may sign an agreement voluntarily in the sense that no one held a gun to their head, yet the circumstances may still involve duress or coercion (addressed under Ground 2). The involuntariness ground focuses on whether the party's basic capacity to consent was intact—whether they were competent, sober, and aware of what they were signing.

Ground 2: Fraud, Duress, Coercion, or Overreaching — § 61.079(7)(a)2

The second ground captures a broader range of misconduct. Fraud in this context means that one party made material misrepresentations—about their assets, debts, or other relevant facts—that induced the other to sign. Duress means improper pressure that overcame the party's free will. Coercion and overreaching describe situations where one party's superior bargaining position was used to impose terms on the other.

A classic duress scenario involves presenting the agreement for the first time hours before the wedding ceremony, with the implicit threat that the wedding will be canceled if the other party does not sign. Florida courts have recognized that the emotional and social pressures surrounding an imminent wedding can constitute duress, particularly when combined with a significant disparity in bargaining power.

Ground 3: Unconscionability Plus Lack of Disclosure — § 61.079(7)(a)3

The third ground requires the challenging party to prove two things: (1) the agreement was unconscionable when it was executed, and (2) before signing, the party did not receive fair and reasonable disclosure of the other party's property and financial obligations, did not voluntarily waive the right to such disclosure, and did not have—or reasonably could not have had—adequate knowledge of the other's finances.

Both elements must be satisfied. An unconscionable agreement that was accompanied by full financial disclosure will be enforced. Conversely, if disclosure was inadequate but the agreement itself was not unconscionable, it will also be enforced. This two-part test makes Ground 3 the most difficult to prove.

Unconscionability is evaluated as of the time the agreement was signed, not at the time of divorce. A prenup that appeared reasonable when both parties were young professionals but seems dramatically unfair 25 years later, after one party became far wealthier, is not unconscionable under this test if the terms were within the range of reasonableness at execution.

§ 61.079(9): Limitation of Actions

Plain-English Explanation

This provision protects a spouse who discovers a problem with the prenup during the marriage but does not want to challenge it immediately—perhaps to avoid disrupting the relationship. The statute of limitations clock does not start running until the marriage ends. A spouse cannot lose the right to challenge a prenup simply because they waited years after discovering grounds for a challenge.

Practical Implications

The tolling provision means that a challenge to a prenup is typically raised as a defense or counterclaim during divorce proceedings. A party does not need to file a preemptive lawsuit during the marriage to preserve their challenge rights. However, the statute preserves equitable defenses, including laches (unreasonable delay causing prejudice). A spouse who waits an excessively long time after discovering a problem—and where the delay prejudices the other spouse—could still face an equitable bar to their challenge.

How § 61.079 Interacts with Other Florida Statutes

A prenuptial agreement does not exist in isolation. It interfaces with several other provisions of Florida law that govern property division, support, and special asset classes.

§ 61.075: Equitable Distribution

Florida's equitable distribution statute governs the division of marital assets and liabilities in divorce. A valid prenuptial agreement can override the default equitable distribution scheme entirely by classifying assets as separate property or by specifying a different division formula. However, the prenup's reach extends only to matters the parties actually addressed. Any asset or category of property not covered by the agreement falls back under § 61.075's equitable distribution framework.

The Florida Supreme Court's decision in Kaaa v. Kaaa, 58 So. 3d 867 (Fla. 2011) clarified the proper methodology for equitable distribution in Florida, establishing a step-by-step process that courts must follow. Where a prenup covers only some assets, the court applies the Kaaa framework to the remaining marital property.

§ 61.076: Retirement Benefits

Retirement accounts, pensions, and similar benefits earned during the marriage are marital assets subject to equitable distribution under § 61.076. A prenuptial agreement can waive or modify each party's claim to the other's retirement benefits. This is a common provision in prenups involving parties who enter the marriage with existing retirement accounts or who participate in defined-benefit pension plans. The prenup should specifically identify each retirement account or plan and state clearly whether the other spouse's interest is waived.

§ 61.08: Alimony

Florida's alimony statute establishes the types of alimony a court may award (bridge-the-gap, rehabilitative, and durational) and the factors courts consider. Following the 2023 alimony reform (SB 1416, effective July 1, 2023), permanent alimony is no longer available in Florida. A prenup can modify or eliminate alimony, subject to the public-assistance safety valve in § 61.079(7)(b). When drafting an alimony waiver, it is prudent to address the waiver's interaction with each type of alimony that § 61.08 authorizes, to avoid ambiguity about whether the waiver was intended to be comprehensive.

Article X, § 4: Florida Homestead

Florida's homestead protection under Article X, Section 4 of the state constitution presents unique challenges for prenuptial agreements. Homestead property receives strong constitutional protection, including restrictions on devise (the right to pass the property by will) when a surviving spouse exists. A prenup can include a waiver of homestead rights, but the waiver must be carefully drafted to address both the constitutional protections and the specific statutory requirements for waiving spousal homestead interests.

Common-Law Marriage Recognition

Florida abolished common-law marriage effective January 1, 1968. However, under Smith v. Anderson, 821 So. 2d 323 (Fla. 2d DCA 2002), Florida courts recognize common-law marriages validly established in other states. If a couple entered a valid common-law marriage in another jurisdiction and later seeks to enforce a prenuptial agreement in Florida, the question of when the marriage "took effect" for purposes of § 61.079(5) may require analysis of the other state's common-law marriage requirements.
