TL;DR: Prenuptial agreements are recognized in all 50 states and D.C., but only 29 states plus D.C. have adopted the Uniform Premarital Agreement Act (UPAA/UPMAA). Nine states follow community property rules; the other 41 use equitable distribution, and "equitable" doesn't always mean "equal." State-specific rules on waiting periods, counsel, and disclosure determine whether your prenup actually holds up.If you're researching prenup law, you've probably already noticed that the rules seem to shift depending on where you live, or where you might live next. That's because they do. A prenuptial agreement is a contract about marriage, and marriage is governed almost entirely by state law. The result is fifty-one different rulebooks (counting D.C.), with real differences in what makes an agreement enforceable.
The good news is that the differences cluster around a small number of questions: Has the state adopted a uniform model law? How does it handle property acquired during marriage? Does it impose timing requirements, counsel requirements, or precise disclosure rules? Once you know those answers for your state, the rest of the picture comes into focus.
This is a long post, and it's meant to be scanned. The state-by-state table below is the showpiece. The sections around it give you the framework you need to read it.
If you're brand new to prenups, our prenup primer is a gentler place to start. Otherwise, read on.
Why state law matters for your prenup If you don't write your own prenup, your state has already written one for you. The default rules in your state's family code, marital property statutes, and case law decide who owns what, who owes what, and what happens to it all if the marriage ends. A prenup is how you opt out of some of those defaults and write your own terms instead.
That makes state law the foundation of every prenup conversation. The same provision (say, a waiver of future spousal support) might be routine in one state and unenforceable in another. The same level of financial disclosure might be more than enough in Texas and fall short in Massachusetts.
Prenups have also become more common, which is part of why this question matters more now than it did a decade ago. According to a 2023 Harris Poll for Axios , roughly 20% of married Americans have a prenup, with 47% of engaged or married Millennials and 41% of engaged or married Gen Z reporting they have one. The conversation is mainstream. The rules underneath it are still local.
The UPAA and UPMAA: the closest thing to a national standard In 1983, the Uniform Law Commission drafted a model law called the Uniform Premarital Agreement Act (UPAA) to make prenup rules more consistent from state to state. The idea was simple: people move, and a contract written under one state's rules shouldn't fall apart the moment a couple crosses a state line. In 2012, the Commission released an updated version, the Uniform Premarital and Marital Agreements Act (UPMAA), which added stronger safeguards around voluntariness, disclosure, and access to counsel.
Twenty-nine states plus the District of Columbia have adopted some version of the UPAA or UPMAA: Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Maine, Montana, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, North Dakota, Oregon, Rhode Island, South Dakota, Texas, Utah, Virginia, West Virginia, and Wisconsin. The remaining 21 states recognize prenups under their own statutes and case law.
Adoption isn't uniform in practice. Each state that adopts the UPAA can (and often does) modify it. California, for example, has a UPAA-based statute but adds the seven-day delivery rule and the spousal-support counsel rule that are uniquely Californian. So "UPAA state" tells you the framework; it doesn't tell you the whole story. As Linda Ravdin's overview for the ABA Family Law Section notes, the UPAA and UPMAA differ meaningfully on enforcement standards, and even within the UPAA states the case law has evolved in different directions.
In the 21 non-UPAA states, courts evaluate prenups under each state's own enforceability tests. Many of those tests are stricter than the UPAA baseline. Roughly fourteen states, by Ravdin's count, apply some form of "second look" doctrine, which means a court can refuse to enforce a prenup that was fair when signed but has become unconscionable by the time of divorce. Massachusetts is a well-known example.
Map showing UPMAA adoption by state, from uniformlaws.org Community property vs. equitable distribution The single biggest split in U.S. marital property law is between community property states and equitable distribution states.
In community property states, most assets and debts acquired during the marriage are considered jointly owned 50/50 by default, regardless of whose name is on the title or which spouse earned the income. There are nine community property states: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin. The federal government recognizes the same list in IRS Publication 555 , which is what couples in those states use to figure out how to file taxes.
In the other 41 states (plus D.C.), courts apply equitable distribution. The court divides marital property based on what it considers fair, taking into account things like the length of the marriage, each spouse's contributions, earning capacity, and post-divorce needs. "Equitable" doesn't always mean "equal." A long marriage with a stay-at-home parent might result in a 60/40 split. A short marriage between two earners might be closer to 50/50. The point is the judge has discretion that doesn't exist in community property states.
A few states sit in a hybrid space. Alaska, South Dakota, and Tennessee allow couples to opt in to community property treatment by agreement. Florida and Kentucky have some community property elements available by trust or election. These are the exception, not the rule.
If you're in a community property state, a prenup is often the cleanest way to designate certain assets, like a business you brought into the marriage or an inheritance you expect to receive, as separate property. If you're in an equitable distribution state, a prenup can lock in predictability around an outcome that would otherwise depend on a judge's read of the facts.

Key state-specific rules worth knowing A handful of states have procedural rules precise enough to derail a prenup if you get them wrong. These are the ones worth knowing in detail.
California. California is a UPAA state, but the California Family Code adds two important rules that most other states don't have. First, the final draft of the prenup must be delivered to both parties at least seven days before signing. This is about the version each party signs, not the first draft they exchange. Second, if the agreement includes a waiver of spousal support, a party waiving spousal support must have been represented by independent legal counsel at the time the agreement was signed. There is no workaround for the counsel requirement on a spousal-support waiver in California.
New York. New York has not adopted the UPAA, but New York Domestic Relations Law § 236(B)(3) recognizes prenups so long as they are in writing, signed by both parties, and acknowledged with the same formality as a deed. The substantive test is that the agreement must be "not unconscionable" both when signed and when enforced. New York courts look closely at financial disclosure.
Florida. Florida is a UPAA state and does not require independent counsel. The most important Florida-specific issue is around surviving-spouse rights. If your prenup waives those rights, Florida Statutes § 61.079 and § 732.702 require the agreement to specifically address elective share, intestate share, homestead, exempt property, and family allowance. A waiver that only addresses "homestead rights" leaves the other four categories of surviving-spouse claims intact. Florida also requires two subscribing witnesses under Florida law for surviving-spouse waivers. Recording is conditional rather than required: if the prenup addresses real property and a party wants to record it, recording rules apply.
Texas. Texas adopted the UPAA in Texas Family Code Chapter 4 . Because Texas is a community property state, prenups often focus on identifying and protecting separate property. If a party declines independent counsel, Texas expects a signed written waiver. Disclosure rules apply unless explicitly waived in writing.
New Hampshire. New Hampshire has not adopted the UPAA, and its rules come from case law. Courts have strongly recommended that a prenup be presented at least 30 days before the wedding, and case law expects each party to have independent counsel. None of these are statutory requirements, but they are the practical bar that New Hampshire courts apply. Earlier is always safer.
Massachusetts. Massachusetts applies a "first look" test (fairness at signing, including disclosure and counsel) and a "second look" test (whether the agreement is still fair when it's enforced). Detailed, item-by-item financial disclosure is the expectation.
Equitable distribution applies in most of these states, and "equitable" doesn't always mean "equal." If you're in any equitable distribution state, that's worth keeping in mind when you think about what a divorce court would do without a prenup.
For a deeper look at what enforceability actually requires in any state, see our companion piece on everything you need to know about getting a prenup .
What happens if you move? Choice-of-law clauses, explained Couples move. Jobs change. Family pulls people across state lines. A prenup signed in one state can absolutely follow you to another, but it doesn't always do so cleanly.
Most states will honor a prenup that was validly signed under another state's law, but the new state's courts will still apply their own public policy when enforcement comes up. So a spousal-support waiver that was valid in your old state might be reviewed under the new state's rules. A disclosure standard that was sufficient in your old state might be tested against the new state's expectations.
A choice-of-law clause is a provision in the prenup that says which state's law governs the agreement. A well-drafted clause specifies that the law of the original state applies regardless of where the parties later live. Courts often (though not always) honor these clauses, particularly when the chosen state has a meaningful connection to the parties (one of you lived there, was married there, or owned property there).
The clause isn't magic. Some states will override a choice-of-law clause if applying it would violate a strong local public policy. But a properly drafted clause is the single best protection a mobile couple can build into their prenup.
If your life is already changing in big ways (new job, new state, a child on the way), our piece on what to do if things change after your prenup walks through how to handle amendments and updates. If a postnup conversation comes up after marriage, consult with independent legal counsel about a postnuptial agreement; it's a separate process from drafting a prenup.
Frequently Asked Questions Are prenuptial agreements legal in all 50 states? Yes. Prenuptial agreements are recognized in all 50 states and the District of Columbia. The requirements for a valid, enforceable prenup vary by state. Some require independent legal counsel, others impose timing rules, and the standards for financial disclosure differ. A prenup that's airtight in one state may face challenges in another, which is why state-specific drafting matters.
Which states have adopted the Uniform Premarital Agreement Act? Twenty-nine states plus D.C. have adopted a version of the UPAA or its 2012 update, the UPMAA: Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Maine, Montana, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, North Dakota, Oregon, Rhode Island, South Dakota, Texas, Utah, Virginia, West Virginia and Wisconsin. The other 21 states recognize prenups under their own laws.
What's the difference between community property and equitable distribution states? Nine states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin) treat most assets and debts acquired during marriage as jointly owned 50/50 by default. The other 41 states use equitable distribution, meaning courts divide marital property based on what they consider fair, and "equitable" doesn't always mean "equal." A prenup can override the default in either regime.
Does my prenup still work if we move to a different state? Often yes, but not automatically. Many states honor prenups validly signed elsewhere, but the new state's courts will apply their own public policy rules. A choice-of-law provision, a clause specifying which state's law governs the agreement, significantly improves the odds your prenup travels with you. If you're moving, it's worth having an attorney in the new state review the agreement.
Do both partners need their own lawyer? It depends on the state. California requires independent counsel for each party for a spousal-support waiver to be enforceable. New Hampshire courts have strongly recommended independent counsel for both parties. Most other states allow you to waive counsel in writing, but having your own lawyer always strengthens enforceability. Independent counsel is one of the cleanest ways to show the agreement was voluntary.
Is there a required waiting period before signing a prenup? Most states don't impose one. California is the major exception: the final draft must be delivered to both parties at least seven days before signing. In New Hampshire, courts have strongly recommended signing at least 30 days before the wedding, though it's not a statutory requirement. Earlier is always safer. A rushed prenup is more vulnerable than one signed with time to spare.
Building a prenup that travels with you Fifty-one rulebooks is a lot. The good news is that you don't have to memorize all of them. You need to know your state's framework, the rules that matter most for your situation, and how to draft an agreement that's built for the life you actually plan to live, which may include a move or two.
First serves couples in 46 U.S. states and D.C., with state-specific guidance built into the platform. No 50-state confusion. No legalese. No surprises. If you're ready to start, you can build a prenup with First on your own timeline, and have a licensed family law attorney review it before you sign. For a practical next step, our prenup checklist walks through what to gather before you begin.
Today you is the one drafting the agreement. Future you, possibly in a different state, possibly with a different balance sheet, is the one it has to protect.
