Walking down the aisle in the Big Apple soon? Congratulations on your upcoming marriage! It's a huge step in life, but it's also important to consider a prenuptial agreement to align with your partner on your life goals and also protect your future self. A prenuptial agreement is a contract between two prospective parties that are planning to be married and is a way for both parties to determine how their property and assets can be managed ahead of time, if the marriage ends in divorce or the death of a spouse. But what requirements are there? Do you need a lawyer? Let's dive into everything you need to know about getting a prenup in NYC.
The Uniform Premarital Act was drafted in 1983 with the hopes of creating uniformity across the US as it pertains to prenuptial agreements. In other words, it attempted to create a uniform law template that all states would adopt to make enforcing prenups across the states possible. In 2012, it was revised and renamed the Uniform Premarital and Marital Agreements Act. Currently, twenty-nine (29) States have adopted one of these uniform laws. The State of New York is not one of the twenty-nine States that have adopted the UPAA/UPMAA standards. However, they do allow premarital agreements. If you choose to reside outside New York state after marriage, your New York agreement is not necessarily enforceable, but there is a good chance. Every state has different laws on how it treats out-of-state prenups.
It's not a legal requirement to hire a prenup lawyer in NYC, though hiring one can help increase the odds of enforceability for your prenuptial agreement because New York courts typically consider the presence or absence of an attorney when determining whether to set aside the agreement. In addition, hiring a lawyer can become crucial if you're waiving alimony in New York due to the new alimony waiver requirements laid out by J.M. v. G.V. (2025), which requires specific alimony calculations plus incomes. This can be difficult to do as a non-lawyer. The bottom line? A prenup lawyer isn't required in NYC, but it can help with enforceability and is especially recommended if either party is waiving alimony.
It depends. Generally, the rule of thumb is to choose the state where you plan to reside as a married couple during the marriage. However, if it is not possible to determine what state you'll be living in, it's best to consult with an attorney in your state (and the states you are considering). As a reminder, a "choice of law clause" is the clause in your prenup that states which state law governs the creation and enforcement of your prenup. This is important because it also generally says what laws govern the creation of the agreement, meaning how it is created, signed, and executed, such as whether it requires witnesses, notarization, independent legal counsel, or financial disclosures. The state you choose can have a huge impact on whether your prenup is considered valid and enforceable down the line, especially if you divorce in a different state. That’s why it’s important to thoughtfully select the governing law and make sure your prenup is drafted in compliance with that state’s specific requirements.
A Premarital Agreement can specify what happens to property and assets in the event of the death of a spouse or divorce. In New York, an agreement can specify, for example:
If there is a waiver of spousal support (also known as spousal maintenance in New York), the clause must contain specific calculations of the future alimony calculations within the waiver with respective income amounts. This rule stems from a recent 2025 decision (J.M. v. G.V., (2025). The court has discretion and ultimately the final say if the agreement is deemed “unconscionable,” meaning unfair. If the child has been born prior to the marriage, child support and custody may be included, however the court has discretion to change or modify the arrangement.
In New York, prenups are governed by the Domestic Relations Law Section 23 (B)(3) and by case law, unlike the states that follow the UPAA/UPMAA guidelines. Here is what is needed for a NYC prenup to be enforced:
The prenup should also be done within a “reasonable” amount of time before the wedding, so there is no later recourse for one member of the party to claim that he or she signed under duress or was coerced into signing the agreement.
A prenup in NYC can be considered unenforceable if the agreement:
Agreements can also be unenforceable if they include incentives for divorce, are deceptive in nature, or have unfair clauses. Unfair clauses, for example, may be overly one-sided, require one party to get cosmetic surgery, or lose weight.
There are additional items that may be included in a NYC premarital agreement, but may not end up being enforceable. Issues regarding custody and child support can be written into the agreement, but the courts ultimately have the final say. Other issues that may or may not be enforceable are clauses dealing with infidelity or initiating divorce. These types of clauses have "questionable enforceability" because many of these issues have not been addressed by a New York statute or case law, so it's unclear how it would shake out in the event it were heard by a higher court.

Here are some more important terms and statutes that you should be aware of when trying to understand the laws in New York.
Case law is the legal term for the court opinions that help us understand how New York courts treat prenuptial agreements, should they ever be challenged during a divorce.
Months prior to their wedding, Mr. Werther presented the soon-to-be Mrs. Werther with a Prenuptial Agreement. She had approximately four months to look at it and was encouraged to take it to an attorney, but did not. The agreement had provisions for the division of property, assets, the waiver of alimony, and a child support plan. The morning of the wedding, the soon-to-be Mrs. Werther had not yet signed, and the couple went and had the agreement signed shortly before the wedding. When the couple later divorced, Mrs. Werther attempted to get the agreement invalidated because she claimed she signed under duress, and that Mr. Werther committed fraud, with the exception of the child support provision.
As you can see, getting a prenuptial agreement in NYC is as easy as 1-2-3. And hiring a prenup lawyer in NYC isn't strictly required, though it is highly recommended, especially if you are waiving alimony. Prenuptial agreements in NYC are very much enforceable as long as you steer clear of questionable clauses, overly unfair clauses, and follow the requirements to create a valid agreement. So, with that said, go on and get that prenup inked so you can focus on the fun aspects of wedding planning, like picking your flowers and planning your bachelorette party. Happy planning!
