Florida Prenup Before the E-2 Treaty-Investor Visa: Marrying While One Partner Funds the Business (2026)

By Nadia Pazos, Family Law Attorney, Pazos Law Group · Updated September 13, 2026

A couple arrives in South Florida as visitors, one partner starts building the business that will support an E-2 treaty-investor application, and the wedding is planned before the filing. One partner contributes all of the investment capital and holds assets across borders — foreign companies, a Panama private-interest foundation, tax residency in more than one country. The other partner arrives with little on paper. This page is about the Florida prenuptial agreement that couple should sign before the wedding, and what belongs in it.

The Situation: Marriage First, Then the E-2 Application

The E-2 classification is for a national of a treaty country investing in a U.S. enterprise. USCIS states the requirement as being “a national of a country with which the United States maintains a treaty of commerce and navigation.” The State Department’s treaty-country list at 9 FAM 402.9 includes Canada (E-2 effective January 1, 1994), Panama (E-2 effective May 30, 1991) and Paraguay (E-1 and E-2 effective March 7, 1860), among many others.

Three USCIS-stated facts shape the wedding timeline for a couple in this position:

• The spouse comes along regardless of nationality. USCIS: “Treaty investors and employees may be accompanied or followed by spouses and unmarried children who are under 21 years of age. Their nationalities need not be the same as the treaty investor or employee.” The regulation says the same: the nationality of a spouse or child “is not material” to their classification, 8 C.F.R. § 214.2(e)(4). But derivative status attaches to a spouse — which is why the marriage happens before the application.
• The E-2 spouse can work. USCIS: “Spouses of E-2 workers in valid E-2 or E-2S status are considered employment authorized incident to status.” That matters to the fairness of the prenup: the non-investing partner is not locked out of earning in the United States.
• A couple already in the U.S. may seek a change of status. USCIS: “If the treaty investor is currently in the United States in a lawful nonimmigrant status, they may file Form I-129 to request a change of status to E-2 classification” — and a request for E-2 classification “may not be made on Form I-129 if you are physically outside the United States.” Whether to change status from a visitor admission or apply at a consulate abroad is an immigration-law decision; consult an immigration attorney. This page addresses only the Florida marital agreement.

One more immigration fact bears directly on the prenup: the investment itself must be real and committed. USCIS requires the capital to be “substantial in relationship to the total cost of either purchasing an established enterprise or establishing a new one” and describes investment as placing capital “at risk in the commercial sense with the objective of generating a profit,” and the enterprise may not be “marginal” — one without “the present or future capacity to generate more than enough income to provide a minimal living for the treaty investor and his or her family” (8 C.F.R. § 214.2(e)(14), (15)). So by the wedding day, one partner has typically already moved significant capital into a Florida enterprise. Who owns that enterprise if the marriage ends is exactly what the prenup decides.

Why the Agreement Should Be Signed Before the Wedding

Florida’s premarital-agreement statute, § 61.079, governs agreements signed before marriage. Sign before the wedding and the couple gets the statute’s clear rules: the § 61.079(3) formalities, the eight permitted subjects, the defined defenses. After the wedding, § 61.079(6) permits amendment, revocation or abandonment only by a written agreement signed by both parties, and a from-scratch postnuptial agreement rests on case law — Casto v. Casto, 508 So. 2d 330 (Fla. 1987) — rather than on the statute. For a couple whose wedding date is driven by an application timeline, the sequence is straightforward: disclosure and drafting first, signatures, then the wedding, then the filing.

Does a wedding scheduled around a filing make the prenup rushed? The statute sets no signing deadline — there is no Florida counterpart to California’s seven-calendar-day rule, Cal. Fam. Code § 1615(c)(2). Timing instead bears on voluntariness under § 61.079(7)(a)1.: an agreement first produced days before a wedding that cannot be moved invites a challenge. Start early enough that neither the wedding nor the application is hostage to the negotiation.

What Florida Law Lets the Agreement Do: the Eight Subjects of § 61.079(4)(a)

A Florida premarital agreement may address eight enumerated subjects, § 61.079(4)(a)1.–8.:

1. The rights and obligations of each party in property of either or both of them — wherever acquired or located;
2. The right to buy, sell, use, transfer, manage and control property;
3. The disposition of property upon separation, dissolution, death, or any other event;
4. The establishment, modification, waiver, or elimination of spousal support;
5. The making of a will or trust to carry out the agreement;
6. Ownership rights in and disposition of a life-insurance death benefit;
7. The choice of law governing the construction of the agreement; and
8. Any other matter not in violation of Florida public policy or a law imposing a criminal penalty — a catch-all, so the list is open, not closed.

Two points for this couple. First, “property” under § 61.079(2) expressly includes income and earnings, both active and passive — so the agreement can decide what happens to the E-2 enterprise’s profits and growth during the marriage, not just the enterprise itself. Second, the single exclusion: the right of a child to support may not be adversely affected by a premarital agreement, § 61.079(4)(b). If children come, Florida child-support law applies no matter what the prenup says.

The Investor Partner’s Disclosure List

The defenses to enforcement in § 61.079(7)(a) — involuntary execution; fraud, duress, coercion or overreaching; unconscionability coupled with inadequate disclosure — are where one-sided agreements fail. When one partner contributes everything and holds it through cross-border structures, the disclosure schedule is the load-bearing wall. For the investor partner in this situation it should enumerate, at minimum:

• The E-2 investment capital — the amount committed or earmarked for the U.S. enterprise, and its source (sale of a foreign business, savings, family funds);
• The U.S. enterprise’s papers — shareholder or operating agreements, capitalization, who holds what percentage;
• Interests in foreign companies — each entity, the country, and the approximate value of the interest;
• The Panama private-interest foundation (or similar structure) — the founder’s role, the assets the foundation holds, and who benefits from it (see below);
• Tax residencies — each country where either partner files or is treated as resident, because it signals where assets and income sit;
• Pre-marriage intellectual property — software, brands, patents or content created before the wedding, especially anything the new business will use;
• Foreign real estate and any debt secured by it; and
• Expected income from the enterprise — because income is “property” under § 61.079(2), the schedule should not stop at balance-sheet assets.

A precise Florida footnote: for death-time waivers of spousal rights, § 732.702(2) states that no disclosure is required for an agreement executed before marriage. That is not a reason to skip disclosure — fair disclosure is what defeats the unconscionability defense of § 61.079(7)(a)2. in a dissolution — but it is a reason the schedule is attached to the prenup itself rather than left to a statute.

Choice of Law, for a Couple Who May Not Stay

E-2 is a nonimmigrant classification. The couple may naturalize on some later path, or may sell the business and go home, or move to a third country. That is why § 61.079(4)(a)7. — the choice of the law governing construction of the agreement — is the clause to decide deliberately rather than by template.

For a Canadian couple, one primary-source contrast shows why the decision is not cosmetic. Florida requires only a signed writing, § 61.079(3). Québec’s Civil Code, by contrast, provides that “marriage contracts shall be established by a notarial act en minute, on pain of absolute nullity” (Civil Code of Québec, art. 440). Marital-agreement law also differs among Canada’s common-law provinces. Pazos Law Group does not opine on Canadian law: if the agreement may ever be enforced in Canada, have counsel in the relevant province review it — before the wedding, while the terms can still be adjusted — and record in the agreement which law the couple chose and why.

The Panama Foundation Question

A private-interest foundation separates legal title from benefit: the foundation, not the founder, owns the assets, while beneficiaries — often including the founder — receive the benefit. When one partner comes to a Florida prenup holding such a structure, the agreement should confront it rather than ignore it:

• Name it in the disclosure schedule — the foundation, the country, the assets it holds, the partner’s role (founder, council member, beneficiary), and any letter of wishes;
• Decide how distributions are treated — if the foundation pays out to the founder-partner during the marriage, is that separate property or income the agreement addresses under § 61.079(2)?
• Decide what happens to assets moved in or out during the marriage — transfers between a spouse and a foundation are exactly the transactions a later dispute will scrutinize; and
• Note what the prenup cannot do — § 61.079 contains no provision addressing the rights of creditors or other third parties; the agreement binds the spouses to each other, not the foundation, its council, or anyone else.

What Panamanian law requires of the foundation itself is a question of Panamanian law, on which this firm does not opine — coordinate with counsel in Panama. The Florida prenup’s job is narrower and fully achievable: disclose the structure, and fix between the spouses how it is treated.

If You Later Leave the United States

Three Florida rules travel well and should be understood at signing:

• Changing the deal takes signatures, not circumstances. After the marriage, the agreement can be amended, revoked or abandoned only by a written agreement signed by both parties, § 61.079(6). Selling the business, losing the status, or moving home does not by itself change the prenup.
• Claims wait. Any statute of limitations applicable to an action asserting a claim for relief under a premarital agreement is tolled during the marriage, § 61.079(9) — the years abroad do not quietly extinguish rights under the agreement.
• Enforcement abroad is a foreign-law question. Whether a court in Canada, Panama, or anywhere else would give effect to a Florida agreement is for counsel in that jurisdiction. Couples who already hold a foreign agreement and are moving to Florida have the mirror-image problem — see our foreign and out-of-state prenup review page.

Practical Numbers for the Florida Wedding Itself

Signing the prenup costs the couple nothing in government fees — there is no filing; § 61.079(3) requires only the signed writing. The Florida marriage licence is $86.00 (standard), or $61.00 after a state-approved premarital course; the licence is valid for 60 days, and the 3-day waiting period applies to Florida residents (verified at the Miami-Dade, Broward and Palm Beach clerks). For perspective on what the agreement is for: filing for dissolution of marriage in those same clerks’ offices costs $409.00.
