High-Net-Worth Prenuptial Agreements in Florida

By Nadia Pazos, Managing Partner, Pazos Law Group · Updated August 11, 2026

A high-net-worth premarital agreement is a classification problem before it is a negotiation. Florida’s equitable-distribution statute sorts every asset into marital or nonmarital, then applies an equal-division premise under § 61.075(1). This page works through the statutory provisions that decide where operating companies, fund and partnership interests, inherited money, trusts, real property, retirement plans, life insurance, and offshore holding structures land — and which of those outcomes a premarital agreement can lawfully change. Pazos Law Group drafts and reviews these agreements across Miami-Dade, Broward, and Palm Beach counties, in English and Spanish.

What does Florida law actually let a prenuptial agreement control?

Florida adopted the Uniform Premarital Agreement Act in 2007; it is codified at Fla. Stat. § 61.079 and, by § 61.079(1), applies only to proceedings under the Florida Family Law Rules of Procedure. Two definitional points matter more to a large estate than anything in the negotiation. First, § 61.079(2)(a) defines a premarital agreement as one “made in contemplation of marriage and to be effective upon marriage” — which is why § 61.079(5) makes it effective on marriage and no earlier. Second, the statutory definition of property is deliberately wide:

“‘Property’ includes, but is not limited to, an interest, present or future, legal or equitable, vested or contingent, in real or personal property, tangible or intangible, including income and earnings, both active and passive.” — Fla. Stat. § 61.079(2)(b)

Contingent, future, and equitable interests are therefore contractible: an unfunded trust remainder, an unexercised option, a capital account in a fund, an earn-out. So are income and earnings, active and passive — a distinction that decides how distributions from a nonmarital portfolio are treated.

§ 61.079(4)(a) then lists eight permitted subjects, which read better as a drafting checklist than as boilerplate:

• § 61.079(4)(a)1. — rights and obligations in property of either or both, “whenever and wherever acquired or located.”
• § 61.079(4)(a)2. — the right to buy, sell, transfer, encumber, or otherwise manage and control property during the marriage.
• § 61.079(4)(a)3. — disposition of property on separation, dissolution, death, or any other stated event.
• § 61.079(4)(a)4. — establishing, modifying, waiving, or eliminating spousal support.
• § 61.079(4)(a)5. — the making of a will, trust, or other arrangement to carry out the agreement.
• § 61.079(4)(a)6. — ownership rights in and disposition of the death benefit from a life insurance policy.
• § 61.079(4)(a)7. — the choice of law governing construction of the agreement.
• § 61.079(4)(a)8. — any other matter not violating Florida public policy or a law imposing a criminal penalty.

After the wedding, § 61.079(6) permits amendment, revocation, or abandonment only by a written agreement signed by the parties, again enforceable without consideration. An estate that changes shape — a liquidity event, a new holding company, a second residence — should be re-papered under that subsection rather than by conduct.

Why does a business you owned before the wedding become partly marital?

Start with the favourable rule. Under § 61.075(6)(b)1., assets acquired before the marriage — and assets acquired in exchange for them — are nonmarital. A company owned on the wedding day starts out as separate property, and so does the entity that later replaces it in an exchange of interests.

Then read the provision that does most of the damage in high-net-worth cases:

“The enhancement in value and appreciation of nonmarital assets resulting from the efforts of either party during the marriage or from the contribution to or expenditure thereon of marital funds or other forms of marital assets, or both.” — Fla. Stat. § 61.075(6)(a)1.b.

Two independent triggers, either one sufficient: effort by either party, or marital funds spent on the asset. An owner who runs the business supplies the first. A passive holder who meets a capital call, a management fee, or a property tax bill out of a joint account supplies the second. Note also that the effort of either party counts — a spouse who never held equity but worked in the business generates marital value inside the other spouse’s separate asset.

The evidentiary burden compounds it. § 61.075(8) presumes everything acquired after the date of marriage is marital and places the burden of overcoming that presumption on the party claiming otherwise. And § 61.075(11) abolished special equity, directing that such claims be asserted either as a request for unequal distribution under subsection (1) or “as a claim of enhancement in value or appreciation of nonmarital property” — which channels the dispute straight back into § 61.075(6)(a)1.b.

The premarital agreement is the direct answer, because § 61.075(6)(b)4. classifies as nonmarital those assets and liabilities “excluded from marital assets and liabilities by valid written agreement of the parties,” together with anything acquired in exchange for them. The clause that matters is not the one naming the company; it is the one addressing enhancement, appreciation, and reinvested earnings.

How does a Florida court value a closely held business or fund interest?

Chapter 2024-237, Laws of Florida, effective 1 July 2024, added § 61.075(6)(a)1.f., which for the first time writes a valuation standard into the statute. Sub-sub-subparagraph (I) fixes fair market value as the standard of value. Sub-sub-subparagraph (II) is the operative rule for owner-operators:

“If there is goodwill separate and distinct from the continued presence and reputation of the owner spouse, it is considered enterprise goodwill, which is a marital asset that must be valued by the court.” — Fla. Stat. § 61.075(6)(a)1.f.(II)

Sub-sub-subparagraph (III) adds that evidence a sale would require a covenant not to compete does not, on its own, preclude a finding of enterprise goodwill. For a professional practice or a founder-dependent services business, the enterprise/personal goodwill line is frequently the largest number in the case. For a holding company, a fund interest, or a real estate partnership it usually is not — there the argument runs to discounts for lack of marketability and control, which the statute leaves to the evidence.

Timing is a separate lever. Under § 61.075(7) the cut-off for classifying an asset as marital is the earliest of a valid separation agreement, a date that agreement sets, or the filing of the petition. The date for valuing it is whatever the judge “determines is just and equitable under the circumstances,” and the subsection expressly allows different assets to be valued as of different dates. An agreement that specifies methodology, appraiser selection, and valuation date replaces that discretion with a term the parties chose.

What happens to inherited wealth, family gifts, and trust distributions?

Inherited and gifted wealth begins protected. § 61.075(6)(b)2. makes nonmarital any asset “acquired separately by either party by noninterspousal gift, bequest, devise, or descent,” plus assets acquired in exchange for it. § 61.075(6)(b)6. covers real property acquired the same way, so long as legal title has not been transferred to the parties as tenants by the entireties.

Income is where families lose the protection without noticing:

“All income derived from nonmarital assets during the marriage unless the income was treated, used, or relied upon by the parties as a marital asset.” — Fla. Stat. § 61.075(6)(b)3.

Trust distributions or portfolio income routed into a joint account and spent on household expenses for a decade is precisely the fact pattern that clause describes. An agreement can provide in advance that distributions from a defined list of nonmarital sources remain nonmarital however they are banked, and can pair that term with an account-titling protocol so the paper trail matches the contract.

Titling carries its own statutory consequences. § 61.075(6)(a)2. presumes real property held as tenants by the entireties to be marital, whether acquired before or during the marriage; § 61.075(6)(a)3. applies the same presumption to jointly titled personal property; and § 61.075(6)(a)4. requires clear and convincing evidence to overcome the gift presumption. Under § 61.075(6)(a)1.d. an interspousal gift of real property cannot be made at all without a writing complying with § 689.01. Adding a spouse to the deed of an inherited house is, under these provisions, a documented transfer of half of it.

How is real property — including passive appreciation — divided?

Since 2018 Florida has had a statutory formula for the marital share of a mortgaged nonmarital property. § 61.075(6)(a)1.c. makes marital both the principal paid down from marital funds and a portion of the passive appreciation, computed by multiplying that passive appreciation by a coverture fraction. The numerator is the total principal paid from marital funds on all notes and mortgages during the marriage; the denominator is the value of the property at marriage, at acquisition, or at the first such encumbrance, whichever is latest. The formula is not discretionary:

“The court shall apply the formula specified in this subparagraph unless a party shows circumstances sufficient to establish that application of the formula would be inequitable under the facts presented.” — Fla. Stat. § 61.075(6)(a)1.c.(V)

That codification followed Kaaa v. Kaaa, 58 So. 3d 867 (Fla. 2010), where the Florida Supreme Court held that passive appreciation on nonmarital real property can be subject to equitable distribution when marital funds paid down the encumbrance. For a couple holding several encumbered properties — a residence, a rental, land held through an LLC — the calculation runs separately for each, and sub-sub-subparagraph (IV) caps the total marital portion at the net equity in the property on the valuation date.

An agreement can displace the formula outright for identified properties, or keep the formula and instead fix in advance which account counts as “marital funds” for mortgage service. The second approach is often easier for the other party to accept and produces the same clarity.

What about retirement plans, deferred compensation, and life insurance?

Deferred compensation is not a grey area in Florida. § 61.076(1) is categorical:

“All vested and nonvested benefits, rights, and funds accrued during the marriage in retirement, pension, profit-sharing, annuity, deferred compensation, and insurance plans and programs are marital assets subject to equitable distribution.” — Fla. Stat. § 61.076(1)

The same list appears at § 61.075(6)(a)1.e. Note the two limiting words: accrued and during the marriage. Balances contributed before the wedding remain nonmarital under § 61.075(6)(b)1.; growth on them is tested against § 61.075(6)(a)1.b. An agreement can fix the pre-marriage balance by stipulated figure rather than leaving a decades-old statement to be reconstructed, and can address non-qualified deferred compensation and unvested awards that no plan administrator will ever segregate for you.

Life insurance sits in two places at once. The plan itself falls within § 61.076(1), while § 61.079(4)(a)6. separately authorises the parties to contract about ownership rights in and disposition of the death benefit — the provision to use where a policy funds a buy-sell agreement or an irrevocable trust.

Can a prenup waive alimony under Florida’s current statute?

Yes. § 61.079(4)(a)4. expressly permits the parties to establish, modify, waive, or eliminate spousal support. What has changed is the baseline the waiver is measured against. Since the 2023 reform, § 61.08(1)(a) lists the available forms exhaustively:

“In a proceeding for dissolution of marriage, the court may grant alimony to either party in the form or forms of temporary, bridge-the-gap, rehabilitative, or durational alimony, as is equitable.” — Fla. Stat. § 61.08(1)(a)

Permanent alimony is absent from that list. The remaining forms are bounded by number. Bridge-the-gap may not exceed 2 years under § 61.08(6). Rehabilitative may not exceed 5 years under § 61.08(7)(c). Durational is unavailable after a marriage lasting under 3 years, and § 61.08(8)(b) caps it at 50 percent of the length of a short-term marriage, 60 percent of a moderate-term marriage, or 75 percent of a long-term marriage — brackets that § 61.08(5) sets by rebuttable presumption at under 10 years, 10 to 20 years, and 20 years or longer. § 61.08(8)(c) caps the amount at the lesser of the obligee’s reasonable need or 35 percent of the difference between the parties’ net incomes.

One statutory floor survives any waiver. Under § 61.079(7)(b), if a support provision leaves one party eligible for public assistance at separation or dissolution, the court may order support notwithstanding the agreement — but only to the extent necessary to avoid that eligibility. In practice, high-net-worth agreements more often set a formula (a fixed sum per year of marriage, or a schedule of lump-sum payments) than a bare waiver, because a term with real economic content is a much harder target under § 61.079(7)(a)3.

Does a prenup also waive the elective share, homestead, and exempt property?

Only if it is executed the way the Probate Code requires, which is not the way § 61.079(3) requires. This is the most common technical defect on an otherwise sophisticated agreement.

The stake is defined by § 732.2065: “The elective share is an amount equal to 30 percent of the elective estate.” Because the elective estate reaches well beyond probate assets, 30 percent of it can dwarf anything at issue in a dissolution. The waiver mechanism is § 732.702(1):

“The rights of a surviving spouse to an elective share, intestate share, pretermitted share, homestead, exempt property, family allowance … may be waived, wholly or partly, before or after marriage, by a written contract, agreement, or waiver, signed by the waiving party in the presence of two subscribing witnesses.” — Fla. Stat. § 732.702(1)

Three consequences follow. First, two subscribing witnesses are required, while § 61.079(3) requires only a writing signed by both parties and does not require notarisation at all. An agreement that satisfies Chapter 61 but not § 732.702(1) can be fully enforceable on divorce and ineffective on death. Second, the same subsection provides that a waiver of “all rights,” or equivalent language, in the property or estate of a present or prospective spouse operates as a waiver of every right on that list — so the phrase carries far more freight than it appears to. Third, § 732.702(2) requires fair disclosure of the estate only where the waiver is executed after marriage; the statute states that “no disclosure shall be required for an agreement, contract, or waiver executed before marriage.” That is a concrete advantage of doing this work before the wedding rather than after. § 732.702(3) adds that no consideration beyond execution is necessary.

Chapter 61 does not override any of this. § 61.079(10) provides that the Premarital Agreement Act “does not alter the construction, interpretation, or required formalities of, or the rights or obligations under, agreements between spouses under s. 732.701 or s. 732.702.” Both statutes must be satisfied, in the same document, on the same day.

Can we choose another state’s law for offshore and cross-border holdings?

Florida expressly allows it. § 61.079(4)(a)7. lists “the choice of law governing the construction of the agreement” among the permitted subjects, and Florida courts have enforced such provisions in premarital agreements — see Waton v. Waton, 887 So. 2d 419 (Fla. 4th DCA 2004). A choice-of-law clause is not a shield against Florida public policy, and § 61.079(4)(a)8. makes that limit explicit for every other subject as well.

The location of an asset is irrelevant to classification. § 61.079(4)(a)1. reaches property “whenever and wherever acquired or located,” and nothing in § 61.075(6)(a)1.a. limits marital assets to those situated in the United States. A foreign holding company, an apartment abroad, or a non-U.S. brokerage account can all form part of the marital estate. The practical constraints are proof and enforcement rather than characterisation, which is why courts frequently equalise with a money judgment instead: § 61.075(10)(a) permits a monetary payment in a lump sum or in installments in lieu of, or to supplement, division in kind, and § 61.075(10)(b) lets the court require security and a reasonable rate of interest on installments.

Where each party holds assets in a different country, the agreement should be reciprocal, translated, and executed with the formalities of both jurisdictions. See also international and cross-border divorce in Florida and, for equity-specific drafting, prenups for startup founders and equity owners.

On what grounds can a Florida court set a premarital agreement aside?

Three, and no others. § 61.079(7)(a) makes the agreement unenforceable if the party resisting it proves:

“1. The party did not execute the agreement voluntarily; 2. The agreement was the product of fraud, duress, coercion, or overreaching; or 3. The agreement was unconscionable when it was executed and, before execution of the agreement, that party: a. Was not provided a fair and reasonable disclosure of the property or financial obligations of the other party; b. Did not voluntarily and expressly waive, in writing, any right to disclosure of the property or financial obligations of the other party beyond the disclosure provided; and c. Did not have, or reasonably could not have had, an adequate knowledge of the property or financial obligations of the other party.” — Fla. Stat. § 61.079(7)(a)

The conjunction in subparagraph 3 is “and,” not “or.” Unconscionability alone is not enough: the challenger must establish unconscionability plus all three of a., b., and c. A signed, itemised financial schedule attached to the agreement defeats a. on its face. Because the elements are cumulative, thorough disclosure is the most reliable defence available — and for an estate whose value is uncertain or expected to move, over-disclosure costs nothing and closes the door on c. as well.

Two procedural points follow. § 61.079(7)(c) provides that “an issue of unconscionability of a premarital agreement shall be decided by the court as a matter of law” — a judge, not a jury, and reviewable as a question of law. And § 61.079(9) tolls any applicable statute of limitations during the marriage, while preserving equitable defences such as laches and estoppel. There is no quiet period after which a defective agreement becomes safe.

What can a Florida prenuptial agreement never do?

Four limits are non-negotiable. § 61.079(4)(b) states flatly that “the right of a child to support may not be adversely affected by a premarital agreement”; child support is computed under the § 61.30 guidelines regardless of what the parties agreed before the child existed. § 61.079(7)(b) preserves the court’s power to order support to avoid public-assistance eligibility. § 61.079(8) provides that where a marriage is determined to be void, the agreement is enforceable only to the extent necessary to avoid an inequitable result. And § 61.079(6) means it cannot be modified by conduct or handshake — only by a signed writing.

A fifth limit is practical rather than statutory: an agreement produced days before a wedding invites exactly the voluntariness challenge § 61.079(7)(a)1. contemplates. For an estate requiring appraisals, entity-level disclosure, and independent counsel on both sides, three to six months before the wedding is a realistic runway.

My practice concentrates on complex-asset family law: closely held businesses, fund and partnership interests, inherited and trust wealth, and cross-border holdings. On premarital agreements I work alongside your CPA, forensic accountant, estate-planning counsel, and corporate counsel, because a document that satisfies § 61.079 but contradicts your trust instruments or your buy-sell agreement has solved only half the problem. I represent one party to any agreement and insist that the other be independently represented — the single most effective protection against a later challenge under § 61.079(7)(a).
