Can You Sign a Florida Prenup in Another State? Choice of Law Under Fla. Stat. § 61.079 (2026)

By Nadia Pazos, Family Law Attorney, Pazos Law Group · Updated August 7, 2026

Fla. Stat. § 61.079 — Florida’s Uniform Premarital Agreement Act — nowhere requires that a premarital agreement be signed inside Florida, and § 61.079(4)(a)7. expressly lets the parties contract about the choice of law. What that clause is actually worth depends on where enforcement is later sought.

Can a Florida Prenup Be Signed While You Are Outside Florida? (§ 61.079(3))

Yes. The formalities subsection is short and complete on its face. Fla. Stat. § 61.079(3), headed “FORMALITIES,” provides in full: “A premarital agreement must be in writing and signed by both parties. It is enforceable without consideration other than the marriage itself.”

Read the list of what that subsection does not say. It does not say the signature must occur within Florida. It does not say either party must be a Florida resident. It does not say the wedding must take place in Florida. It does not require simultaneous signing, a particular county, or a Florida address on the signature page.

What the statute does key on is the marriage. § 61.079(2)(a) defines a premarital agreement as “an agreement between prospective spouses made in contemplation of marriage and to be effective upon marriage,” and § 61.079(5) states that “a premarital agreement becomes effective upon marriage of the parties.” The operative event is the marriage — not the geography of the signing.

So a fiancée in Massachusetts, Texas or Bogotá can sign a Florida-drafted premarital agreement where she is. Nothing in Fla. Stat. § 61.079 makes the signing location a validity question.

Does Florida Require Notarization or Witnesses for a Prenup?

Section 61.079 itself does not. The only formalities § 61.079(3) imposes are a writing and both signatures, and it adds that the agreement “is enforceable without consideration other than the marriage itself.” There is no notary requirement and no subscribing-witness requirement anywhere in § 61.079.

That is not the end of the analysis, and this is where out-of-state signers get caught. § 61.079(10) provides: “This section 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.”

Fla. Stat. § 732.702 is titled “Waiver of spousal rights.” If your premarital agreement waives elective share, homestead, exempt property, family allowance or similar death-time rights, § 732.702(1) says those rights may be waived “by a written contract, agreement, or waiver, signed by the waiving party in the presence of two subscribing witnesses.”

Two sentences of § 732.702(1) then speak directly to out-of-state signing:

• “The requirement of witnesses shall be applicable only to contracts, agreements, or waivers signed by Florida residents after the effective date of this law.”
• “Any contract, agreement, or waiver executed by a nonresident of Florida, either before or after this law takes effect, is valid in this state if valid when executed under the laws of the state or country where it was executed, whether or not he or she is a Florida resident at the time of death.”

Section 732.702(2) adds that “no disclosure shall be required for an agreement, contract, or waiver executed before marriage,” and § 732.702(3) that no consideration beyond execution is necessary. Note that the § 732.702(2) sentence is a Probate Code rule about death-time waivers; it does not relax the disclosure standard that § 61.079(7)(a)3. applies to divorce-time enforcement.

The practical consequence: a bare writing with two signatures satisfies § 61.079(3), but a premarital agreement that also waives death-time spousal rights is drafted against § 732.702 as well. That is why careful Florida drafting routinely has both parties sign before a notary and two witnesses even though § 61.079 does not demand it. Ask your reviewing attorney which formalities your specific document needs.

Does a Florida Choice-of-Law Clause Work? Fla. Stat. § 61.079(4)(a)7.

Florida law expressly permits the clause. § 61.079(4)(a) opens: “Parties to a premarital agreement may contract with respect to:” and item 7 on that list is “The choice of law governing the construction of the agreement.”

Three precise observations about that eleven-word provision:

1. It authorizes, it does not command. The statute says the parties may contract about choice of law. It does not say that every court, in every state, must then apply the chosen law.
2. Its stated object is “construction.” The text names the law governing construction of the agreement — how its words are read. A well-drafted clause is usually written more broadly, but the statutory authorization itself is phrased in terms of construction.
3. There is an outer boundary. § 61.079(4)(a)8. permits “any other matter, including their personal rights and obligations, not in violation of either the public policy of this state or a law imposing a criminal penalty.” Public policy is a real limit on what parties can agree to.

Florida recognizes party choice elsewhere in chapter 61 as well. § 61.052(5) provides that “the court may enforce an antenuptial agreement to arbitrate a dispute in accordance with the law and tradition chosen by the parties.” That is a separate provision about arbitration, but it shows the same legislative posture: Florida courts are receptive to what prospective spouses chose in writing.

Which State’s Law Actually Applies When Someone Tries to Enforce It?

It depends on where enforcement is sought. That is the honest answer, and any page that gives you a cleaner one is overstating.

Start with the statute’s own scope limit. § 61.079(1) states that the section “may be cited as the ‘Uniform Premarital Agreement Act’ and this section applies only to proceedings under the Florida Family Law Rules of Procedure.” By its terms, the § 61.079 framework — the formalities of (3), the permitted subjects of (4), the enforcement grounds of (7) — operates in Florida family-law proceedings.

So the practical sequence is:

• If the dissolution is filed in Florida, the Florida court applies § 61.079, including § 61.079(7)(a), and your § 61.079(4)(a)7. clause is squarely within what Florida law lets you contract for.
• If the dissolution is filed somewhere else, that court decides — under its own state’s conflict-of-laws rules and its own public policy — whether to honor the Florida choice-of-law clause. This page does not predict how any particular other state will rule, because that is a question of that state’s law, not Florida’s.

Where the divorce gets filed is often the whole ballgame, and it is frequently decided by residency and timing rather than by the agreement. That is why the paragraph below on Fla. Stat. § 61.021 matters more than most people expect.

Why Is a Choice-of-Law Clause Not Self-Executing?

A choice-of-law provision is a term of a contract. It does not enforce itself. Four things limit it even in a Florida proceeding:

1. Someone has to raise it. A clause nobody pleads is a clause nobody applies.
2. Public policy. § 61.079(4)(a)8. conditions the parties’ freedom on not violating “the public policy of this state or a law imposing a criminal penalty.”
3. Children are carved out. § 61.079(4)(b) is one sentence: “The right of a child to support may not be adversely affected by a premarital agreement.” No choice-of-law clause changes that. Child support is calculated under § 61.30, and time-sharing is decided under § 61.13 — where § 61.13(2)(c)1. has, since July 1, 2023, applied a rebuttable presumption that equal time-sharing is in the best interests of the child.
4. The public-assistance override. § 61.079(7)(b) allows a court, “notwithstanding the terms of the agreement,” to require support where a spousal-support waiver would leave one party “eligible for support under a program of public assistance at the time of separation or marital dissolution.”

What If We Get Married in Another State or Another Country?

Nothing in § 61.079 keys validity to the place of the ceremony. The agreement is “made in contemplation of marriage and to be effective upon marriage” (§ 61.079(2)(a)) and “becomes effective upon marriage of the parties” (§ 61.079(5)). A wedding in Massachusetts, Colombia or Spain still triggers the agreement.

One edge case is addressed expressly. § 61.079(8) provides: “If a marriage is determined to be void, an agreement that would otherwise have been a premarital agreement is enforceable only to the extent necessary to avoid an inequitable result.”

Separately, if the marriage never happens at all, the § 61.079(5) condition is never satisfied — there is no marriage to make the agreement effective.

What If We Sign Now and Move to Florida Later?

This is the common pattern for couples who sign while one of them still lives out of state. Two statutes then matter.

Timing of any Florida case. Fla. Stat. § 61.021, titled “Residence requirements,” is a single sentence: “To obtain a dissolution of marriage, one of the parties to the marriage must reside 6 months in the state before the filing of the petition.” Grounds are then pleaded under § 61.052(1)(a) (the marriage is irretrievably broken), and under § 61.19 no final judgment may be entered “until at least 20 days have elapsed from the date of filing the original petition,” absent a showing that injustice would result from the delay.

What the agreement is displacing. Absent an enforceable premarital agreement, a Florida court divides property under § 61.075. Two pieces of that statute are what most out-of-state signers are actually worried about: § 61.075(6)(b) defines nonmarital assets, and § 61.075(6)(a)1.b. treats as marital the enhancement in value of a nonmarital asset resulting from marital labor or marital funds. In Kaaa v. Kaaa, 58 So. 3d 867 (Fla. 2010), the Florida Supreme Court addressed passive appreciation of a nonmarital home.

Section 61.079 anticipates exactly this. § 61.079(2)(b) defines “property” broadly as “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.” Those last five words are the drafting hook for premarital-asset appreciation.

Finally, § 61.079(9) tolls limitations: “Any statute of limitations applicable to an action asserting a claim for relief under a premarital agreement is tolled during the marriage of the parties to the agreement,” though laches and estoppel remain available.

What If We Sign in Florida and Then Move Away?

Again, the honest answer is that it depends on the forum. If neither spouse has resided in Florida for the 6 months § 61.021 requires before filing, a Florida dissolution is not available on that basis, and the case is realistically filed where one of you now lives. That other court applies its own rules to decide what to do with the Florida choice-of-law clause.

What does not change: the agreement is still a signed contract; § 61.079(6) means it stays in force unless you undo it properly — “after marriage, a premarital agreement may be amended, revoked, or abandoned only by a written agreement signed by the parties,” and that amendment or revocation “is enforceable without consideration.” A move, standing alone, is not a revocation.

What Can a Florida Prenup Cover Under § 61.079(4)(a)?

The statute gives an eight-item list. Parties may contract with respect to:

1. the rights and obligations of each party in property “whenever and wherever acquired or located” (§ 61.079(4)(a)1.) — language that itself contemplates out-of-state assets;
2. the right to buy, sell, use, transfer, encumber “or otherwise manage and control property” (§ 61.079(4)(a)2.);
3. “the disposition of property upon separation, marital dissolution, death, or the occurrence or nonoccurrence of any other event” (§ 61.079(4)(a)3.);
4. “the establishment, modification, waiver, or elimination of spousal support” (§ 61.079(4)(a)4.) — the alimony framework it displaces is § 61.08, rewritten in 2023;
5. the making of a will, trust or other arrangement to carry out the agreement (§ 61.079(4)(a)5.);
6. ownership and disposition of a life insurance death benefit (§ 61.079(4)(a)6.);
7. “the choice of law governing the construction of the agreement” (§ 61.079(4)(a)7.); and
8. any other matter not violating Florida public policy or a criminal statute (§ 61.079(4)(a)8.).

And the one hard stop: § 61.079(4)(b) — “the right of a child to support may not be adversely affected by a premarital agreement.”

On What Grounds Can a Florida Prenup Be Set Aside? (§ 61.079(7)(a))

In a Florida family-law proceeding, § 61.079(7)(a) makes a premarital agreement unenforceable if the party resisting it proves one of three things:

1. “The party did not execute the agreement voluntarily” (§ 61.079(7)(a)1.);
2. “The agreement was the product of fraud, duress, coercion, or overreaching” (§ 61.079(7)(a)2.); or
3. the agreement “was unconscionable when it was executed” and, before execution, 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” beyond what was 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” (§ 61.079(7)(a)3.a.–c.).

Note the conjunctive structure of item 3: unconscionability alone is not enough; all three disclosure sub-elements must also be shown. And § 61.079(7)(c) assigns the question to the judge: “An issue of unconscionability of a premarital agreement shall be decided by the court as a matter of law.”

A precision point about Casto. Casto v. Casto, 508 So. 2d 330 (Fla. 1987), is the decision family lawyers cite for setting aside marital agreements on grounds including fraud, duress, coercion and overreaching. Casto concerns postnuptial and marital settlement agreements, not agreements governed by § 61.079, which was enacted later. For a premarital agreement within § 61.079, the operative test is the statute’s own § 61.079(7)(a) list. Do not let anyone blur the two bodies of law when telling you what your document is worth.

Why Should the Party Being Asked to Sign Have Independent Florida Counsel?

Be clear about what the statute does and does not say: § 61.079 does not require that either party have a lawyer. An agreement is not void because one side was unrepresented. But every ground in § 61.079(7)(a) is about what happened to the signing party before the signature, and independent review is how those facts get built or checked.

A Florida attorney reviewing a document drafted by the other side’s Florida counsel is looking at, among other things:

• Voluntariness and timing — the § 61.079(7)(a)1. and (7)(a)2. exposure created by a signature demanded days before the wedding.
• Disclosure — whether there is a schedule of assets and liabilities, and whether any § 61.079(7)(a)3.b. written waiver of further disclosure is one you actually want to give.
• Alimony — whether § 61.079(4)(a)4. is being used to waive support entirely, and what § 61.08 would otherwise have provided.
• Appreciation and income — whether the § 61.079(2)(b) “active and passive” language, § 61.075(6)(a)1.b. and Kaaa are addressed, or quietly left to argument.
• Children — whether anything in the draft brushes against § 61.079(4)(b), § 61.30 or § 61.13.
• Death-time rights — whether an elective-share or homestead waiver is present and whether § 61.079(10) and § 732.702 formalities were followed.
• The choice-of-law clause itself — whether § 61.079(4)(a)7. was used at all, and how broadly it is drafted.

If you are the party being asked to sign, the review is also the cheapest point in the whole timeline. Our Florida prenuptial agreement checklist sets out what to gather first, and fees vary by complexity — a limited-scope review of an already-drafted agreement is generally a fraction of the cost of drafting one from scratch.

When Do You Actually Need Counsel in Both States?

Not always. Florida counsel can review a Florida-law agreement for a signer who lives anywhere. But add a lawyer in the other state when:

• The divorce is realistically going to be filed there, not in Florida — because § 61.021 will not be satisfied by either spouse.
• Real property sits outside Florida, and its transfer, titling or homestead treatment is governed there.
• The agreement waives death-time spousal rights and the waiving party is a nonresident — § 732.702(1) makes a nonresident’s waiver valid in Florida “if valid when executed under the laws of the state or country where it was executed,” which is a question about that other state’s law.
• The other state has its own premarital-agreement statute whose requirements — independent counsel, waiting periods, notarization — you want checked before signing.
• Retirement or pension interests require an order entered in another forum.

We say this plainly because it is an ethical limit, not a marketing position: a Florida attorney cannot advise you on another state’s law. Where a second jurisdiction is genuinely in play, the right structure is Florida counsel on the Florida-law questions and local counsel on theirs.
