Marrying Out of State? Where to Get Your Prenup

Where should you get a prenup if you're marrying out of state?

Your prenup should be governed by the law of the state where you plan to live, not the state where you're holding the ceremony. The wedding venue is a logistics decision; your prenup is a legal contract, and its validity depends on the law that governs its terms.

A prenuptial agreement drafted in one state remains valid even if the marriage takes place in another. That's because a prenup is, at its core, a contract between two people. Like other contracts, it can include a clause that specifies which state's laws apply when the agreement is interpreted or enforced. This clause, called a choice-of-law provision, is the mechanism that determines governing law, not the location of the wedding.

So if you live in Texas, plan to stay in Texas, and are flying to Hawaii for the ceremony, your prenup should almost certainly be drafted under Texas law, with a choice-of-law clause designating Texas.

How choice-of-law clauses decide which state's law governs your prenup

A choice-of-law clause is a provision in your prenup that tells a court which state's laws to apply when questions arise about the agreement's validity, interpretation, and the specific terms it covers, such as property division, spousal support, and financial responsibilities.

Under the Restatement (Second) of Conflicts of Laws §187, the widely cited framework for contract disputes, a court will generally apply the law of the state chosen by the parties unless that state has no substantial relationship to the contract or the parties. In practice, this means your choice-of-law clause will be honored as long as you have a real connection to the state you select, such as living there, owning property there, or having signed the agreement there.

Most states respect these clauses, but enforcement is not perfectly uniform. Some states do not consistently defer to choice-of-law provisions, particularly when the agreement's terms conflict with the public policy of the state where divorce proceedings are filed. For example, if your prenup designates California law but you divorce in a state that considers certain spousal-support waivers unenforceable, the forum state's court may refuse to apply that portion of the agreement.

It's also worth distinguishing a choice-of-law clause from a forum-selection clause. A choice-of-law clause determines which state's rules apply to your prenup. A forum-selection clause determines which state's courts will hear any dispute. Including both can add another layer of clarity, especially for couples who anticipate moving.

Wedding state vs. home state vs. future state: which one matters

The state where your wedding ceremony takes place rarely governs your prenup. The ceremony state matters for your marriage license and the legal act of getting married, but your prenuptial agreement is a separate contract with its own governing-law rules.

Your domicile, the state where you intend to permanently reside, is typically the guiding factor when choosing which state's law should govern your prenup. If both partners already live in the same state and plan to stay there, the decision is straightforward: choose that state.

Complications arise when a couple is unsure where they'll settle. If you're both in different states, or you anticipate a move for work, the general guidance is to choose the state where you have the strongest current ties and where you're most likely to live long-term.

The key takeaway: without a clear choice-of-law clause, courts typically look at where the contract was executed or where the parties were domiciled at signing. A clear clause removes that ambiguity.

Why state prenup laws differ and what all states require

Every state in the U.S. recognizes prenuptial agreements, but the rules for what you can include, how the agreement must be executed, and when a court can set it aside vary from jurisdiction to jurisdiction. Approximately 26 states have adopted the Uniform Premarital Agreement Act (UPAA), though each adopting state has included its own modifications. The remaining states rely on their own statutes or case law.

Despite these differences, courts across the country look at a shared set of baseline requirements:

• Written agreement. Oral prenups are not enforceable anywhere in the U.S.
• Signed before the marriage. The agreement must be executed before the wedding, and a valid marriage must follow.
• Financial disclosure. Both partners must have the opportunity to review the other's financial situation. Full, honest disclosure is a threshold requirement.
• Opportunity for independent legal counsel. While not every state requires each partner to have their own attorney, the opportunity to consult one is expected.
• Not against public policy. Provisions involving child support or child custody, for example, are generally not enforceable in a prenup because courts retain authority over those matters.
• Substantive fairness. A majority of states impose some level of fairness review, particularly on spousal support and alimony terms.

State-specific differences highlight why the governing state matters. In Florida, for instance, a spouse cannot waive the right to attorney fees or interim spousal support in a prenuptial agreement. A prenup drafted under another state's law that includes such a waiver could face enforceability problems if the couple later divorces in Florida. These variations make it important to draft under the right state's rules from the start.

Where to sign and how to execute a valid out-of-state prenup

Proper execution is just as important as the substance of your agreement. Regardless of which state's form or law you use, best practices include having the agreement notarized and signed in front of at least two witnesses. Not every state requires both, but covering these bases helps if the agreement ever needs to be enforced in a different jurisdiction.

Where you physically sign the prenup matters more than people realize. If your agreement does not include a choice-of-law clause, the general conflict-of-law rule is that the validity of the contract is determined by the law of the state where it was entered into. That means signing in a state whose laws you didn't intend to follow could create unexpected complications.

Independent counsel for each partner is highly recommended for an enforceable prenup. Ideally, each attorney should be licensed in the state whose law will govern the agreement, since they'll need to confirm the prenup complies with that state's specific requirements.

As Michael C. Cotugno, Esq., Managing Partner of Neptune Legal, puts it: "A premarital agreement doesn't have to be a wedge between partners or a necessary evil that protects assets at the expense of trust and intimacy."

A lawyer-led online option like Neptune lets each partner work with their own independent attorney without being limited to a single geographic area. When both parties use Neptune-network lawyers, each party has an independent attorney they choose themselves, which can be especially useful when partners live in different states or when the governing state isn't where either partner is physically located.

International marriages and cross-border considerations

Couples marrying abroad or involving a partner from another country face additional layers of complexity. A marriage performed in a foreign country is generally recognized as valid in the United States if it was conducted in compliance with that country's laws. To confirm validity, individuals can check with their state's Attorney General or complete a Certificate of Witness to Marriage.

However, the enforceability of a prenuptial agreement across international borders is less straightforward. Contract terms that are perfectly enforceable under U.S. law may violate the public policy or legal requirements of another country. In Mexico, for example, courts can override prenuptial agreements if doing so serves the interests of justice. Religious marriage contracts, such as the Islamic mahr, are generally not treated by U.S. courts as equivalent to a secular prenuptial agreement for purposes of property division or alimony.

For couples with international ties, the prenup should include both a choice-of-law clause and a forum-selection clause specifying which country's (and which state's) courts and laws will govern disputes. An attorney familiar with both jurisdictions should review the agreement to flag any provisions that may be unenforceable abroad.

Next steps for couples planning a cross-state prenup

Here's a practical framework for getting your out-of-state prenup right:

1. Decide on your intended domicile. Talk with your partner about where you plan to live after the wedding. This conversation shapes everything else.
2. Choose the governing state's law. Select the state with the strongest connection to your life together, usually your intended domicile, and make sure your prenup includes a clear choice-of-law clause designating that state.
3. Engage independent attorneys. Each partner should work with their own attorney, ideally one licensed in the governing state. This is especially important when you're dealing with multi-state or international factors.
4. Execute the agreement properly. Sign with notarization and witnesses, following the requirements of both the governing state and the state where you physically sign.
5. Start the conversation early. Routine planning conversations about finances, expectations, and goals can begin well before you involve attorneys. The legal drafting goes more smoothly when both partners have already talked through priorities.

For couples with straightforward circumstances and a clear domicile, the process is usually manageable. When multi-state property, complex assets, or international elements are involved, qualified family law attorneys familiar with the relevant jurisdictions are essential to getting the agreement right.
