A Florida prenuptial agreement -- also called a premarital agreement or "prenup" -- is a written contract signed before marriage that determines how property, debts, and support will be handled if the marriage ends in divorce or death. Florida adopted the Uniform Premarital Agreement Act in Chapter 61, Part II of the Florida Statutes. A properly drafted, properly executed prenup is a powerful tool for protecting premarital assets, family businesses, and inheritances.
Florida Statutes § 61.079(4) lists topics that a prenup may address:
A prenup cannot adversely affect a child's right to support. Child support is a right of the child, not a right the parents can waive. The same is true of time-sharing: parents cannot bind a future court's best-interest analysis by contract. Provisions that attempt to do either are unenforceable, though they will not necessarily void the rest of the agreement.
Florida Statutes § 61.079(7) sets out when a prenup is enforceable. The challenging party must prove one of the following:
In practice, the most common enforceability fights involve disclosure -- whether the financial schedule attached to the agreement accurately reflected the wealthier spouse's assets and income at the time of signing.
A Florida prenup can be amended or revoked after marriage only by a written agreement signed by both spouses. No consideration is required beyond the marriage itself. A subsequent oral modification is not enforceable.
Florida adopted the Uniform Premarital Agreement Act in 2007, and it is codified at Florida Statutes § 61.079. The Act displaced an older line of common-law cases and gave practitioners a single statutory framework. A premarital agreement under the Act must be in writing and signed by both parties. No consideration beyond the marriage itself is required, and the agreement becomes effective on the date of marriage. If the parties never marry, the agreement never takes effect.
One feature of the statute that is often overlooked is its reach. Section 61.079 applies to agreements signed in contemplation of marriage. It governs not just classic "rich spouse, poor spouse" contracts, but also second-marriage agreements designed to preserve assets for children of a prior marriage, agreements between spouses of similar wealth who want clear rules for their respective businesses, and international agreements that include a Florida choice-of-law clause.
Beyond the bulleted statutory list, several substantive areas deserve closer attention because they are where most negotiation effort goes.
Florida is an equitable distribution state under Florida Statutes § 61.075. Without an agreement, the active appreciation of a nonmarital asset during the marriage can become marital property if marital labor or marital funds contributed to that appreciation. A well-drafted prenup defines which assets remain separate, addresses the treatment of both passive and active appreciation, and specifies how mortgage paydown, capital improvements, and reinvested earnings will be characterized. Without explicit language, a closely held business or rental real estate held in one spouse's name before marriage can develop a substantial marital component over a long marriage.
Section 61.079(4)(a)(4) permits the modification or elimination of alimony, and Florida courts will enforce a clear alimony waiver in most circumstances. There is, however, a public-policy floor. If enforcement of an alimony waiver would leave one spouse eligible for public assistance, the court may, under § 61.079(6), order the other spouse to provide support to the extent necessary to avoid that result, notwithstanding the agreement. Practical drafting therefore distinguishes between a complete waiver of all forms of support and a partial waiver that excludes only certain categories such as permanent or durational alimony while preserving bridge-the-gap or rehabilitative alimony.
For couples with assets in multiple states or countries, a choice-of-law clause designating Florida law and a forum clause designating a Florida circuit court can prevent forum-shopping later. Courts in other states will generally honor a Florida choice-of-law clause if there is a reasonable connection to Florida, such as residence or property.
A prenup can require one spouse to maintain a specified amount of life insurance for the other or for the children, and it can dictate the beneficiary designations. These provisions are often used in second marriages to ensure that children of a prior relationship are not disinherited.
For an entrepreneur, the prenup is the central document that protects the business. It can specify that the business and all interests in successor entities are separate property, that any increase in value is also separate, that marital labor is being compensated by salary rather than by an equity claim, and that the non-owner spouse will execute any documents required by future investors or lenders to confirm the separate character of the interest.
Florida law permits a creditor to look to the marital estate for marital debts. The prenup cannot bind a third-party creditor, but it can allocate responsibility as between the spouses and provide for indemnification if one spouse incurs debt that the parties had agreed would be separate.
A surviving spouse in Florida has the right to an elective share equal to thirty percent of the elective estate under Florida Statutes § 732.2065. Section 732.702 permits a spouse to waive the elective share, the homestead protections of Article X, § 4(c) of the Florida Constitution to the extent waivable, intestate share, family allowance, pretermitted-spouse rights, and the right to be appointed personal representative -- but only by a written contract signed in the presence of two subscribing witnesses. If estate-planning waivers are intended, the prenup must satisfy both the Premarital Act and the witness requirements of § 732.702. A prenup signed only by the parties, without two subscribing witnesses, may still bind them in life but fail to waive elective-share rights at death.
The Act expressly excludes child support from the matters that may be adversely affected by a prenup. Child support belongs to the child, and the parents cannot contract it away. The same principle applies to time-sharing and parental responsibility. A prenup that recites which parent will have majority time-sharing is unenforceable on that point; the future court will apply the best-interest factors of Florida Statutes § 61.13(3) to the facts as they exist at the time. Provisions that violate public policy in other ways -- for example, clauses that purport to penalize a party for reporting domestic violence -- are likewise unenforceable.
So-called "infidelity penalty" or "lifestyle" clauses occupy a gray area. A clause that increases one spouse's alimony or property award if the other spouse has an extramarital affair is not automatically void, but Florida courts scrutinize these provisions for unconscionability, vagueness, and proof problems. Even when such a clause is enforceable in principle, the evidentiary burden of proving the triggering conduct often makes the clause more useful as a settlement tool than as a true contractual remedy.
Florida Statutes § 61.079(7) provides the test for setting aside a prenup. The agreement is presumed enforceable. The party seeking to escape it bears the burden of proving one of three grounds:
All three elements of the unconscionability ground must be proven. A challenger who can show inadequate disclosure but cannot also show unconscionable terms will lose, and vice versa. This makes substantive fairness and procedural fairness two separate inquiries, both of which must be addressed by the proponent of the agreement.
Voluntariness is fact-specific. Florida courts consider the time between presentation and signing, whether the challenging party had counsel, whether the challenging party had a meaningful opportunity to negotiate, the sophistication and education of the parties, and whether the wedding was imminent. A prenup signed the day before the wedding, after invitations are out and family has arrived from out of state, is a much easier target than one signed several months in advance. While the statute does not impose a bright-line waiting period, no responsible Florida family-law attorney recommends presenting a prenup less than thirty days before the ceremony.
The cleanest practice is full written disclosure attached to the agreement as an exhibit: a schedule of assets at fair market value, liabilities, gross income for the prior two years, and significant contingent obligations. The schedule should be signed and dated. If a party wishes to waive further disclosure, the waiver must be in writing, must be voluntary and express, and must reflect that the party already had adequate knowledge of the other party's finances. A boilerplate waiver buried in a long-form agreement is far weaker than a separately initialed waiver supported by a contemporaneous record of conversations between counsel.
Under Florida Statutes § 61.079(6), a premarital agreement may be amended or revoked only by a written agreement signed by both spouses. No new consideration is required. A subsequent oral modification is not enforceable, and conduct alone -- even years of conduct -- generally does not revoke a written prenup. If the parties' circumstances have shifted materially, the cleanest course is a written amendment or a postnuptial agreement that supersedes the prenup in whole or in part.
Successful challenges in Florida tend to involve some combination of the following: a prenup presented for the first time within days of the wedding; no opportunity for independent counsel; financial schedules that omit material assets or grossly understate values; a sophisticated party on one side and a non-English-speaking party on the other without a translation; and substantive terms that leave the challenging spouse destitute. Unsuccessful challenges -- the more common outcome when the proponent has done the work -- typically involve a challenger who had counsel, had weeks or months to review the document, signed financial schedules that were substantially accurate, and now regrets the bargain.
If a divorce is on the horizon and you signed a Florida prenup years ago, do not assume the agreement controls every issue. Review it with counsel against the current facts. Has the document been amended in writing? Were the financial schedules complete? Did the agreement contemplate the assets that exist today, or has the marital estate grown in ways no one anticipated? Are there clauses that violate public policy and that the court will sever? Even an enforceable prenup may leave open questions about child support, time-sharing, and certain categories of marital property accumulated through marital labor that the agreement does not clearly address. The right strategy depends on whether you are the proponent or the challenger, and on the strength of the procedural record.
A postnuptial agreement serves the same function but is signed after the marriage. Postnups are evaluated under common law contract principles rather than the Uniform Premarital Agreement Act, and Florida courts apply heightened scrutiny to them because of the fiduciary relationship between spouses. A postnup is sometimes used to correct or supplement a poorly drafted prenup, although careful redrafting can also be accomplished by amendment to the original premarital agreement.
A Florida prenuptial agreement is one of the most powerful planning documents available to a couple about to marry. It is also one of the most heavily litigated. The difference between an agreement that holds up in court and one that collapses is rarely the substantive terms -- it is the process by which the agreement was negotiated, disclosed, and signed. Our office drafts, reviews, and litigates premarital agreements for clients across Miami-Dade and the surrounding counties, with particular attention to high-asset cases, second marriages, business owners, and international families.
