New York Law: The 2025 Update to Prenuptial Agreement Waiver Requ

New York prenuptial agreements have always had a serious reputation. They are contracts, yes, but they are not the kind of contracts people click through while downloading a parking app. A prenup can decide what happens to property, business interests, future earnings, retirement benefits, estate rights, and spousal maintenance if a marriage ends. In 2025, New York lawyers, engaged couples, and anyone with a spreadsheet labeled “wedding budget final FINAL v4” received an important reminder: waivers in prenuptial agreements must be clear, informed, and properly documented.

The biggest 2025 update is not a brand-new statute that rewrites every New York prenup overnight. Instead, it comes from a significant New York Supreme Court decision, J.M. v. G.V., decided on January 2, 2025. The court held that when a self-represented future spouse waives spousal maintenance in a prenuptial agreement, the waiver must be knowing. In practical terms, that means the agreement should include both parties’ actual incomes and the full presumptive maintenance calculation under New York law. Without that concrete information, a spouse may not truly understand what is being waived.

That sounds technical, but the message is refreshingly human: you cannot fairly give up a financial right if nobody shows you what the right is worth. It is like being asked to sell a vintage watch without being told whether it is worth $50 or “please call Sotheby’s.”

What Makes a Prenuptial Agreement Valid in New York?

Under New York Domestic Relations Law Section 236(B)(3), a prenuptial or postnuptial agreement must satisfy three core requirements. It must be in writing, signed by both parties, and acknowledged or proven in the manner required for a deed to be recorded. In everyday language, that means a properly drafted written agreement, signed by both future spouses, with a proper deed-style notarization.

This formal execution requirement matters. New York courts have long treated the acknowledgment requirement seriously. A beautiful agreement with thoughtful terms can still run into trouble if the signing formalities are sloppy. The law does not reward “close enough” when the document affects major marital rights.

What Can a New York Prenup Cover?

A New York prenuptial agreement may address several major areas. It can define separate and marital property, describe how assets will be divided, waive or modify estate rights, set rules for business ownership, address responsibility for certain debts, and provide for the amount and duration of spousal maintenance. It may also mention child-related expectations, but courts retain authority over child custody and child support based on the child’s best interests and applicable law at the time of divorce.

That last part is important. A prenup can organize adult financial expectations. It cannot lock a future court into an arrangement that fails a child.

The 2025 Update: Why J.M. v. G.V. Matters

In J.M. v. G.V., the parties signed a prenuptial agreement about one week before their 2018 wedding. The husband was not represented by counsel when the agreement was negotiated and signed. Years later, during divorce litigation, he challenged the agreement, arguing that it was unconscionable, fraudulent, and the product of overreaching.

The court did not throw out the entire prenup. In fact, it reaffirmed a familiar New York principle: a properly executed prenuptial agreement is generally presumed valid, and the person challenging it carries a heavy burden. Courts do not usually rewrite a bargain just because, in hindsight, one side wishes the bargain had been warmer, fuzzier, or less financially brutal.

But the court drew a sharp line at the spousal maintenance waiver. The agreement recited the statutory maintenance formula, but it did not include both parties’ actual incomes at the time of signing or the full presumptive maintenance calculation. Because the husband was self-represented, the court held that he could not knowingly waive maintenance without seeing the number he was giving up. As a result, the court vacated the spousal maintenance provision while leaving the rest of the agreement in place.

Knowing Waiver: The New Drafting Standard Everyone Is Talking About

A “waiver” means a person gives up a legal right. A “knowing waiver” means the person understands the right being surrendered. In New York prenup practice, the 2025 lesson is straightforward: if a future spouse is waiving spousal maintenance, the agreement should not merely say, “I waive maintenance.” It should show the math.

For self-represented parties, the agreement should include the income of each party as of the signing date and the full guideline calculation for temporary and post-divorce maintenance, where applicable. It should also explain that the parties are choosing to opt out of that presumptive result. A waiver becomes much harder to attack when the document says, in plain terms: “Here is the statutory calculation. Here is the amount. Here is what you are choosing not to receive.”

This does not mean every maintenance waiver is invalid. It means vague waivers are riskier, especially when one party lacks counsel. The old “sign here and trust me” approach now looks less like efficient drafting and more like handing a judge a red pen.

Why Actual Income Numbers Matter

New York’s maintenance guidelines use income to produce a presumptive support figure. If the agreement does not include income, it cannot calculate the presumptive amount. If it does not calculate the presumptive amount, the waiving party may not know what is being waived.

Consider a simple example. Taylor earns $300,000 a year. Jordan earns $45,000. Their prenup says each waives maintenance forever. Jordan does not have a lawyer. The document mentions that New York has a maintenance formula, but it never shows Taylor’s income, Jordan’s income, or the estimated maintenance amount. Under the 2025 reasoning, that waiver is vulnerable because Jordan may have waived an unknown benefit.

Now compare a stronger version. The prenup lists both incomes, attaches financial disclosure schedules, runs the statutory formula, identifies the presumptive maintenance amount, explains that the parties are opting out, and gives Jordan time to consult independent counsel. That does not guarantee enforcement, because courts still review fairness and public policy, but it puts the waiver on much firmer ground.

Maintenance Waivers Are Not Treated Like Ordinary Contract Clauses

New York courts generally respect contracts. They also respect the freedom of spouses and future spouses to arrange their financial lives. But spousal maintenance provisions receive closer scrutiny than many property clauses. Why? Because maintenance is connected to support, basic financial stability, and public policy.

A property clause might say that a separately titled brokerage account remains separate property. Courts often enforce that kind of clause if the agreement is clear and properly executed. A maintenance waiver, however, asks a court to accept that one spouse gave up future support. That is a more sensitive issue, especially if enforcement would leave the spouse unable to be self-supporting.

The Public Charge Problem Under New York Law

General Obligations Law Section 5-311 adds another guardrail. Spouses cannot contract away support in a way that leaves one spouse incapable of self-support and likely to become a public charge. In J.M. v. G.V., the court noted that the maintenance waiver made no affirmative representation that the waiver would not leave either party at risk of becoming a public charge.

That may sound like lawyerly belt-and-suspenders language, because it is. But it serves a real purpose. A strong prenup should not only show the maintenance calculation; it should also address whether the waiver would leave either party unable to meet basic needs. If the answer is uncertain, the waiver may need limits, conditions, or a different structure.

Does the 2025 Rule Apply Only When Someone Has No Lawyer?

The J.M. v. G.V. decision focused heavily on the fact that the husband was self-represented. That means the narrowest reading is that the full presumptive calculation is required when one or both parties lack counsel. But many New York family law practitioners are treating the decision as a broader best-practice warning.

Why? Because nobody wants to be the test case that argues, “Yes, Judge, we skipped the calculation, but this time everyone had lawyers, so surely it is fine.” That is not a relaxing litigation strategy. It is the legal equivalent of assembling furniture without instructions and hoping the extra bolts are decorative.

The safer drafting approach after 2025 is to include the maintenance calculations in all prenuptial and postnuptial agreements that waive or modify spousal maintenance, whether or not both parties are represented. It is cleaner, more transparent, and easier to defend.

Common Prenup Waiver Mistakes After the 2025 Update

1. Using Generic Waiver Language

A clause that simply says “both parties waive spousal maintenance” may no longer be enough, especially for a self-represented spouse. The agreement should explain the right, show the guideline result, and state the reason for the deviation or waiver.

2. Leaving Out Income Disclosure

Asset schedules are helpful, but maintenance calculations depend on income. A prenup that lists bank accounts and real estate but omits income may be missing the key number needed for a knowing waiver.

3. Signing Too Close to the Wedding

New York courts do not automatically invalidate a prenup because it was signed shortly before the wedding. Still, last-minute signing can fuel claims of pressure or duress. Starting months ahead is smarter, calmer, and less likely to turn a romantic engagement into a document-production thriller.

4. Skipping Independent Counsel

Independent counsel is not always a strict statutory requirement, but it is one of the strongest practical safeguards. Separate lawyers help show that each party understood the agreement and had a meaningful chance to negotiate.

5. Forgetting Severability

A severability clause can help preserve the rest of the agreement if one provision is later invalidated. In J.M. v. G.V., the court vacated the maintenance provision but did not discard the entire prenup. Good drafting plans for that possibility.

How Couples Should Approach a New York Prenup in 2025 and Beyond

The best prenups are not ambushes. They are financial planning documents with better lighting and fewer romantic comedy misunderstandings. Couples should begin early, exchange meaningful financial information, use clear language, and treat the process as a serious conversation rather than a pre-wedding obstacle course.

For a maintenance waiver, the agreement should include current income, the applicable New York guideline calculation, a clear opt-out provision, a statement that each party understands the right being waived, and an acknowledgment that the waiver will not leave either party unable to be self-supporting. If income includes bonuses, business distributions, investment income, or irregular compensation, the disclosure should be specific enough to avoid confusion later.

Business owners should pay special attention. A founder, physician, real estate investor, or creative professional may have income that does not fit neatly into a salary box. The more complex the finances, the more important it is to use schedules, exhibits, and professional valuation language where appropriate.

Practical Experience: What This Update Looks Like in Real Life

In real-world prenup conversations, the hardest part is rarely the legal formula. It is the emotion. People hear “prenup” and imagine one person sliding a contract across a marble table while thunder rumbles outside. In practice, many couples are simply trying to avoid future chaos. One partner may own a small business. Another may expect to pause a career for children. Both may have student loans, family gifts, inherited property, or retirement accounts that deserve careful handling.

The 2025 update changes the tone of those conversations in a helpful way. Instead of treating a maintenance waiver like a magic sentence, lawyers and couples now have a clearer checklist. What are the incomes? What would the guideline calculation produce? What exactly is being waived? Is either person giving up support without independent advice? Would enforcement create hardship? These questions can feel uncomfortable, but they prevent a bigger problem later.

Imagine a couple in Brooklyn. One partner works in tech and earns a high salary with stock units. The other is a freelance designer with uneven income. They both want a prenup because the tech employee has equity and the designer wants clarity, not courtroom roulette. Before 2025, a drafter might have included a broad mutual waiver of maintenance and moved on. After 2025, a careful attorney would slow down, calculate the presumptive maintenance amount, disclose the income assumptions, and explain the consequence of opting out.

That process can actually make the agreement feel fairer. Numbers reduce mystery. A spouse who sees the calculation can decide whether the waiver makes sense, whether a cap is better, or whether support should be waived only after a short marriage. For example, the agreement might say no maintenance is paid if the marriage lasts less than three years, but a limited amount applies after a longer marriage or if one spouse leaves the workforce to care for children. That kind of tailored drafting is often more durable than a dramatic “never, ever, under any circumstances” clause.

Another common experience involves family pressure. Parents sometimes push for prenups when family wealth, business succession, or real estate is involved. That is understandable, but pressure should not become panic. If a prenup appears one week before the wedding, with deposits paid and relatives flying in, the signer may later claim coercion. The better experience is boring in the best way: start early, exchange drafts, allow questions, and make the signing feel like a calm financial decision rather than a hostage negotiation with floral arrangements.

The 2025 lesson is not that prenups are bad. It is that shortcuts are bad. A strong New York prenup can protect both people, preserve separate property, reduce future litigation, and create honest expectations. But when it waives maintenance, especially for a spouse without counsel, it must show the work. In law, as in high school algebra, the answer mattersbut the teacher still wants to see the calculation.

Conclusion

The 2025 update to New York prenuptial agreement waiver requirements is a wake-up call for couples and attorneys. A maintenance waiver should not be vague, rushed, or hidden behind legal fog. It should be supported by real income numbers, statutory calculations, meaningful disclosure, and a clear explanation of what each person is giving up.

For couples, the takeaway is simple: a prenup is strongest when it is transparent. For lawyers, the drafting lesson is even simpler: include the math. A well-prepared agreement may not make wedding planning cheaper, but it can make future litigation far less explosive. And in New York, that counts as romance with a notary stamp.
