Is Your Out-of-State or Foreign Prenup Valid in Florida? What a Florida-Law Review Looks For (2026)

By Nadia Pazos, Family Law Attorney, Pazos Law Group · Updated

Couples arrive in Florida with prenups signed in New York, notarial “separation of property” elections from Colombia or Spain, mahr agreements, and German Eheverträge. Florida courts respect agreements validly made elsewhere — but respect is not a rubber stamp. Comity yields to Florida public policy (Gustafson v. Jensen), Florida formalities govern Florida death-time rights (§ 732.702), and every agreement enforced in a Florida divorce passes through § 61.079 and Casto.

Quick Answer

Will Florida enforce a prenup signed in another state or country?

It depends on the agreement, the law selected, the place and manner of execution, the rights involved, and the forum asked to enforce it. A Florida review examines those questions, the defenses in § 61.079(7)(a), and any death-time formalities under § 732.702. If both spouses agree after marriage, § 61.079(6) permits a signed written amendment, revocation, or abandonment; counsel should determine whether a new or restated agreement is appropriate.

Prenups From Another U.S. State

The easier case first. A premarital agreement validly executed in New York, Texas, or Illinois is a contract, and Florida courts routinely give effect to contracts validly made under sister-state law. Many such agreements also carry their own choice-of-law clause — the same device Florida authorizes in § 61.079(4)(a)7. — and a Florida court will ordinarily honor a reasonable choice of another state’s law for construction of the agreement.

Two caveats. First, when a dissolution is filed here, the case proceeds under Florida procedure, and the § 61.079(7)(a) defenses — involuntary execution; fraud, duress, coercion or overreaching; unconscionability plus inadequate disclosure — are how challenges are actually framed. Second, states differ on important substance: what alimony can be waived, what disclosure suffices, whether independent counsel matters. Terms that appear enforceable elsewhere may raise different issues in Florida, which is precisely what a review identifies. (Signing a Florida prenup while out of state is a different question — see that page.)

Prenups and Marital-Property Regimes From Another Country

Foreign agreements come in two very different shapes. Some are negotiated contracts that look like Florida prenups. Many more are marital-property regime elections: a brief notarial act — sometimes a paragraph — by which a couple in Spain, Colombia, Venezuela, France or Germany opted into separación de bienes or a similar regime, with no disclosure schedules, no counsel, and no negotiation.

Florida analyzes both through comity: courtesy to the laws and judgments of other jurisdictions, extended unless doing so would offend Florida public policy. The Third District’s decision in Gustafson v. Jensen, 515 So. 2d 1298 (Fla. 3d DCA 1987), is the cautionary tale: Florida declined to give effect to a Danish separate-property arrangement where the fairness and disclosure Florida requires were not shown, observing that comity does not apply where it would frustrate an established public policy of this state. On the other side of the ledger, Akileh v. Elchahal, 666 So. 2d 246 (Fla. 2d DCA 1996), enforced an Islamic mahr as an ordinary contract under neutral principles. The lesson of the pair: foreign origin neither dooms nor guarantees an agreement — Florida standards decide.

Married in Italy: separazione dei beni

Italy is a clear example of the regime-election shape. Under art. 159 of the Italian Civil Code, a couple who does nothing is in comunione dei beni — community of property. Art. 162 allows two ways out: a marital convention executed as a notarial public act (atto pubblico, on pain of nullity), or a single declaration choosing separation made in the act of celebration of the marriage itself. Art. 215 then states the whole effect in one sentence: each spouse keeps exclusive ownership of property acquired during the marriage.

Three things follow for a Florida review. First, the election may be one line in the marriage record, and nothing in art. 162 requires financial disclosure or independent counsel for it — the profile Gustafson warns about. Second, art. 162 makes the choice opposable to third parties only when it is annotated in the margin of the marriage record, so the document to bring is a certified extract of the Italian marriage record showing that annotation. Third, art. 215 addresses ownership of acquired property and nothing else: it does not mention maintenance, inheritance or disclosure, which are the questions a Florida court will ask. We describe the Italian requirement here and link its official text; how Florida treats a particular election depends on its facts.

What a Florida-Law Review Actually Examines

  1. Validity where made. Was the agreement properly executed under the law of the place of signing? An agreement invalid at home rarely improves by crossing the border.
  2. Choice of law. What law does the agreement select, and would a Florida court apply it? § 61.079(4)(a)7. blesses such clauses; public policy limits them.
  3. The § 61.079(7)(a) / Casto defenses. How was it signed — when, under what pressure, with what counsel? What was disclosed, in what form? How one-sided is the result? These are the grounds on which Florida agreements actually rise or fall.
  4. Death-time waivers. § 61.079(10) preserves the formalities of § 732.702: waivers of elective share and other spousal death rights require the waiving party’s signature before two subscribing witnesses. Many foreign notarial documents fail this, and Florida real estate raises the stakes — in Kyle v. Kyle, a foreign marital agreement was denied effect over Florida land where Florida formalities were not met.
  5. Substantive terms under current Florida law. Alimony waivers, property schedules, homestead provisions — do they still do what the couple thinks they do?
  6. Translation. A certified English translation, obtained calmly now rather than adversarially at trial.

If the Review Finds Problems: the § 61.079(6) Cure

Finding a concern before a dispute may leave more options. Section 61.079(6) permits spouses to amend, revoke, or abandon a premarital agreement through a writing signed by both parties. Depending on the governing law and the rights addressed, counsel may recommend an amendment or a new or restated postnuptial agreement with appropriate disclosure, separate advice, and execution formalities. See our postnuptial agreement page.

When to Get the Review Done

  • On moving to Florida — before Florida becomes the likely divorce or probate forum.
  • Before buying Florida real estate — homestead and § 732.702 formalities make land the most formality-sensitive asset.
  • Before estate planning — wills and trusts are usually drafted assuming the prenup’s waivers hold.
  • At the first sign of trouble — enforcement and set-aside positions are best understood before positions harden. Our prenup-review cost page explains what a review involves.

Frequently Asked Questions

Is a prenup signed in another U.S. state valid in Florida?

Usually, yes. Florida courts respect contracts validly made elsewhere, and Fla. Stat. § 61.079(4)(a)7. expressly contemplates choice-of-law clauses. But when enforcement is sought in a Florida dissolution, the proceeding runs under Florida procedure, and the agreement remains exposed to the defenses of § 61.079(7)(a) and Casto v. Casto — involuntariness, fraud, duress, coercion, overreaching, and unconscionability coupled with inadequate disclosure.

Is a prenup signed in another country enforceable in Florida?

Often, through comity — but not automatically. Florida courts have declined to enforce foreign marital-property arrangements where doing so would frustrate Florida public policy or where fairness and disclosure were not shown (Gustafson v. Jensen, 515 So. 2d 1298 (Fla. 3d DCA 1987)). Conversely, Florida's Second DCA enforced a religious marriage contract (a mahr) under neutral contract principles in Akileh v. Elchahal, 666 So. 2d 246 (Fla. 2d DCA 1996). Every foreign agreement needs a Florida-law review on its own facts.

Our foreign prenup is really a 'marital property regime.' Does that matter?

Yes. Many civil-law countries (Spain, France, Germany, much of Latin America) marry couples into a default or elected property regime — often a brief notarial election, not a negotiated contract with disclosure schedules. A Florida court asked to apply one will look for the things Florida law cares about: voluntariness, disclosure, fairness. A two-paragraph regime election looks very different from a § 61.079-style agreement, which is why review before a dispute — not during one — matters.

What does a Florida attorney actually check when reviewing an out-of-state or foreign prenup?

The core checklist: (1) validity where executed; (2) what law the agreement chooses and whether a Florida court would apply it; (3) the § 61.079(7)(a) and Casto defenses — how it was signed, what was disclosed, how one-sided it is; (4) whether death-time waivers meet the two-witness formality preserved by § 61.079(10) and § 732.702; (5) whether key terms (alimony waivers, property schedules) work under current Florida law; and (6) translation quality if the agreement is not in English.

We moved to Florida after signing a prenup abroad. Should we do anything?

Have it reviewed now, before it matters. If the review finds weaknesses, § 61.079(6) allows a married couple to amend, revoke, or abandon a premarital agreement by a signed written agreement — in practice, a confirming or restating postnuptial agreement executed with Florida formalities and disclosure can cure most defects while both spouses are still cooperative.

Does an out-of-state prenup control what happens to Florida real estate?

Florida takes its real property seriously. In Kyle v. Kyle, a Florida court declined to give a foreign marital agreement effect over Florida real estate where Florida's execution formalities were not met. If the agreement is meant to control Florida land or homestead rights, it should be checked against Florida formalities — including the two-witness rule of § 732.702 for death-time waivers — and cured if it falls short.

Do foreign-language prenups need a certified translation for a Florida court?

As a practical matter, yes. A Florida judge works in English; an agreement in Spanish, Portuguese, French, or German will need a competent certified translation, and disputes about translation quality become disputes about what was agreed. Getting a professional translation at the review stage — not on the eve of trial — avoids that fight.

We married in Italy under separazione dei beni. Will Florida recognize it?

Often, through comity — but not automatically. Italian Civil Code art. 162 allows separation to be chosen by a single declaration at the wedding, and art. 215 covers only ownership of property acquired during the marriage. Because nothing required disclosure or counsel, a Florida court may ask what Gustafson v. Jensen, 515 So. 2d 1298 (Fla. 3d DCA 1987), asked: were fairness and disclosure shown?
