A prenuptial agreement in New York is a legally binding contract between two people planning to marry that establishes how assets, debts, and spousal maintenance will be handled if the marriage ends in divorce or death. Under New York Domestic Relations Law § 236(B)(3), a prenuptial agreement must be in writing, signed by both parties, and acknowledged before a notary public in the same manner required to record a deed. The January 2025 decision in J.M. v. G.V. significantly strengthened requirements for spousal maintenance waivers, now requiring specific income figures and complete statutory calculations to be valid.

What Is a Prenuptial Agreement Under New York Law?
A prenuptial agreement in New York is a contract executed before marriage that governs the financial rights and obligations of both spouses during the marriage and upon its dissolution, with enforceability standards set by DRL § 236(B)(3). New York courts treat prenuptial agreements as presumptively valid contracts, requiring the challenging party to prove fraud, duress, or unconscionability to invalidate them. The state has not adopted the Uniform Premarital Agreement Act (UPAA), instead relying on state statutes and decades of case law to establish enforceability standards.
The legal framework permits couples to address property division, spousal maintenance, inheritance rights, and debt allocation. However, child custody and child support provisions are not binding on courts, which must always decide these matters based on the child's best interests at the time of divorce. The 2025 J.M. v. G.V. decision from Kings County Supreme Court established that spousal maintenance waivers require specific income disclosures and complete statutory calculations to constitute a knowing waiver.
Formal Requirements for a Valid Prenuptial Agreement in New York
A valid prenuptial agreement in New York must satisfy three statutory requirements under DRL § 236(B)(3): the agreement must be in writing, subscribed (signed) by both parties, and acknowledged or proven in the manner required to entitle a deed to be recorded. Failure to meet any of these requirements renders the agreement unenforceable in a matrimonial action, regardless of how fair or reasonable the terms may be.
Written Form Requirement
Oral prenuptial agreements are completely unenforceable in New York. The written document must clearly identify both parties, state that it is a prenuptial agreement, and contain all material terms the parties wish to enforce. Handwritten agreements are technically valid but professionally drafted documents reduce the risk of ambiguity or missing provisions.
Signature Requirements
Both parties must personally sign the agreement. Electronic signatures may be acceptable under New York's Electronic Signatures and Records Act (ESRA), but traditional ink signatures remain the safest approach for documents that may be challenged years or decades later.
Deed-Style Acknowledgment (Notarization)
New York requires prenuptial agreements to be acknowledged before a notary public using the same standards applied to real property deeds under Real Property Law § 309-a. This means a notary must verify each signer's identity through government-issued identification and certify that each party acknowledged signing the agreement. The notary does not need to witness the actual moment of signing; parties may sign beforehand and later appear before the notary to acknowledge their signatures.
Improper acknowledgment is a common reason prenuptial agreements fail in court. Even if both parties signed and fully intended to be bound, failure to complete the deed-style acknowledgment process can render the entire agreement void. Courts have consistently rejected agreements where notarization was incomplete or procedurally defective.
What Can Be Included in a New York Prenuptial Agreement?
DRL § 236(B)(3) specifically authorizes prenuptial agreements to include provisions addressing four categories: testamentary provisions and waiver of estate rights, ownership and division of separate and marital property, amount and duration of spousal maintenance, and custody and support of children (though child-related provisions are not binding on courts).
Property Division Provisions
Prenuptial agreements can define which assets remain separate property and which become marital property subject to equitable distribution. Couples can specify that certain assets, such as family businesses, investment accounts, or real estate, will remain the separate property of one spouse regardless of how title is held or how long the marriage lasts. Property provisions receive less judicial scrutiny than maintenance provisions and are generally enforced according to their terms if the agreement meets formal requirements.
Spousal Maintenance (Alimony) Provisions
Spousal maintenance provisions in prenuptial agreements face heightened scrutiny under New York law. DRL § 236(B)(3) requires that maintenance terms be fair and reasonable at the time of execution and not unconscionable at the time of final judgment. The January 2025 J.M. v. G.V. decision significantly strengthened this standard by requiring that maintenance waivers include both parties' actual income figures and complete calculations under the statutory formula for the waiver to constitute a knowing relinquishment.
For 2026, the statutory maintenance formula applies to payor income up to $241,000 (increased from $228,000 in 2025). The formula calculates maintenance as the lesser of: (1) 30% of payor income minus 20% of payee income (when no child support is paid), or (2) 40% of combined income minus the payee's income. Prenuptial agreements that waive maintenance should include these specific calculations using both parties' actual or anticipated incomes to survive judicial review.
Estate Planning Provisions
New York prenuptial agreements can include waivers of the right to elect against a spouse's will under EPTL § 5-1.1-A. Without such a waiver, a surviving spouse is entitled to the greater of $50,000 or one-third of the deceased spouse's net estate, regardless of what the will provides. Prenuptial waivers of elective share rights allow individuals with children from prior relationships or significant family wealth to maintain control over estate distribution.
Debt Allocation
Prenuptial agreements can specify that each party remains responsible for their pre-marital debts and that neither party will be responsible for debts the other incurs during the marriage unless jointly obligated. This protection is particularly valuable when one party enters the marriage with significant student loan debt, business obligations, or credit card balances.
What Cannot Be Included in a New York Prenuptial Agreement?
Certain provisions are unenforceable or prohibited in New York prenuptial agreements regardless of how the agreement is structured. Child custody and child support determinations cannot be binding because courts must always decide these issues based on the child's best interests at the time of separation. Couples may include their preferences regarding custody arrangements, but judges are not bound by these provisions.
A prenuptial agreement cannot completely eliminate spousal support if doing so would render one spouse a public charge. Under General Obligations Law § 5-311, no spouse may relieve the other of the obligation to support to the extent that the spouse would become eligible for public assistance. Courts will modify or invalidate maintenance waivers that would produce this result.
Provisions that encourage or reward divorce, sometimes called lifestyle clauses, may face unenforceability challenges. While New York courts have not categorically rejected all lifestyle clauses, provisions that appear designed to incentivize marital dissolution rather than protect legitimate financial interests may be struck down.
Cost of Prenuptial Agreements in New York
The cost of a prenuptial agreement in New York ranges from $1,500 to $10,000 or more depending on complexity, attorney experience, and geographic location, with New York City attorneys typically charging higher fees than upstate practitioners. Simple, straightforward agreements with limited assets and no business interests typically cost $1,500 to $3,500 when one attorney drafts the agreement. Complex agreements involving business valuations, multiple properties, international assets, or significant wealth may cost $5,000 to $20,000 or more.
| Agreement Type | Typical Cost Range | Factors |
|---|---|---|
| Simple (limited assets) | $1,000-$3,000 | Basic property division, standard maintenance terms |
| Moderate complexity | $3,000-$7,500 | Business interests, real estate, retirement accounts |
| High-net-worth | $7,500-$20,000+ | Multiple businesses, international assets, trust planning |
| Prenup review only | $500-$1,500 | Reviewing agreement drafted by other party's attorney |
Because both parties should have independent legal counsel, couples should budget for two attorney fees. Having separate attorneys significantly strengthens the agreement's enforceability by demonstrating that both parties received independent legal advice and understood the agreement's implications. Attorney hourly rates in New York range from $250 to $1,000 per hour depending on experience and location, with flat-fee arrangements available from many practitioners.
How Courts Evaluate Prenuptial Agreement Validity
New York courts apply a presumption of validity to prenuptial agreements that meet the formal requirements of DRL § 236(B)(3), placing the burden on the challenging party to prove grounds for invalidation. The landmark New York Court of Appeals decision in Christian v. Christian (1977) established that prenuptial agreements may be set aside upon proof of fraud, duress, mental incompetence, or fundamental unfairness, but courts will subject these claims to strict scrutiny.
Unconscionability Standard
An unconscionable agreement is one that no reasonable person would make and no honest person would accept, with inequality so strong and manifest as to shock the conscience. Courts apply different timing standards depending on the provision: property distribution provisions are evaluated for unconscionability at the time of execution, while spousal maintenance provisions must be fair and reasonable when made and not unconscionable at the time of final divorce judgment.
Fraud and Misrepresentation
Although New York does not legally require financial disclosure for a prenuptial agreement's validity, concealment of significant assets or misrepresentation of financial circumstances can provide grounds for invalidation. Fraudulent inducement requires proof that one party made material misrepresentations that the other party reasonably relied upon in signing the agreement.
Duress and Overreaching
Signing a prenuptial agreement under extreme pressure, such as being presented with the agreement hours before the wedding ceremony with a threat to cancel, may constitute duress. Courts examine whether the challenging party had a meaningful opportunity to review the agreement, consult with independent counsel, and negotiate terms. However, the mere existence of time pressure does not automatically invalidate an agreement if the party still had a genuine choice.
Lack of Independent Counsel
New York does not require both parties to have independent legal representation for a prenuptial agreement to be valid. However, the J.M. v. G.V. decision demonstrates that courts closely scrutinize agreements signed by unrepresented parties, particularly regarding spousal maintenance waivers. When one party lacks counsel, courts require even clearer evidence that the party understood the rights being waived.
Recent Legal Developments: J.M. v. G.V. (2025)
The January 2025 decision in J.M. v. G.V. from Kings County Supreme Court significantly changed how New York courts evaluate spousal maintenance waivers in prenuptial agreements, requiring specific income disclosures and complete statutory calculations for waivers to be enforceable. Justice Jeffrey S. Sunshine ruled that a maintenance waiver signed by an unrepresented party was invalid because it failed to include both parties' actual incomes and the complete maintenance calculation under DRL § 236(B)(6).
The agreement in J.M. v. G.V. was signed one week before the wedding. The husband, who was not represented by counsel, sought to set aside the prenuptial agreement on grounds of unconscionability and fraud. The court found that while the property distribution provisions remained enforceable due to a severability clause, the maintenance waiver was invalid because the husband could not have made a knowing waiver without understanding what maintenance he would have received under the statutory formula.
Practical Implications for Future Agreements
Following J.M. v. G.V., practitioners should ensure prenuptial agreements containing maintenance waivers include: both parties' current annual incomes, the applicable statutory maintenance formula, the calculated maintenance amount using those incomes, and an explicit acknowledgment that the parties understand what is being waived. Severability clauses have become even more critical, as they allow courts to invalidate problematic provisions while preserving the remainder of the agreement.
Steps to Create an Enforceable Prenuptial Agreement
Creating an enforceable prenuptial agreement in New York requires careful attention to timing, process, and documentation to minimize the risk of successful challenges years or decades later.
1. Begin Early (Minimum 3-6 Months Before Wedding)
Starting the prenuptial agreement process well before the wedding date demonstrates that both parties had adequate time to consider the terms, consult with attorneys, and negotiate modifications. Agreements signed days before the wedding face heightened scrutiny for duress and may be more vulnerable to challenge.
2. Provide Complete Financial Disclosure
Although not legally required, voluntary full disclosure of assets, income, and liabilities significantly strengthens enforceability. Attach financial statements, tax returns, and asset schedules as exhibits to the agreement. This documentation prevents later claims that one party was unaware of the other's true financial picture.
3. Retain Independent Legal Counsel
Both parties should have their own attorneys who can explain the agreement's implications and advocate for their client's interests. Independent representation substantially reduces the risk of successful challenges based on lack of understanding or overreaching.
4. Include Specific Maintenance Calculations
For agreements that address spousal maintenance, include both parties' incomes and the complete statutory calculation showing what maintenance would be under the DRL § 236(B)(6) formula. Explicitly state that the parties understand this amount and are knowingly waiving or modifying their rights.
5. Complete Proper Acknowledgment
Schedule separate notarization appointments where each party appears before a notary public with government-issued identification. The notary must complete the acknowledgment in the form required for deed recording, certifying that each party acknowledged signing the agreement.
6. Include a Severability Clause
A severability clause allows courts to strike individual provisions found unenforceable while preserving the remainder of the agreement. The J.M. v. G.V. decision specifically highlighted the importance of severability clauses in saving agreements with problematic provisions.
Modifying or Revoking a Prenuptial Agreement
Prenuptial agreements can be modified or revoked after marriage through a written postnuptial agreement that meets the same formal requirements as the original prenup under DRL § 236(B)(3). Both parties must consent to any modifications, and the amended agreement must be in writing, signed by both parties, and properly acknowledged before a notary.
Oral agreements to modify or revoke a prenuptial agreement are unenforceable. Couples who wish to change their prenuptial agreement terms should execute a formal amendment or a completely new postnuptial agreement that supersedes the original.
Enforcing a Prenuptial Agreement in Divorce
When a couple with a prenuptial agreement divorces in New York, the agreement is presented to the court during the matrimonial action. If neither party challenges the agreement's validity, courts will generally enforce its terms as part of the divorce judgment. The divorce filing fee in New York is $335 total, consisting of a $210 index number filing fee and a $125 note of issue fee. As of March 2026, verify current fees with your local county clerk.
If one party challenges the prenuptial agreement, the court will conduct a hearing to determine whether grounds for invalidation exist. The challenging party bears the burden of proving fraud, duress, unconscionability, or other grounds by a preponderance of the evidence. Courts will examine the circumstances surrounding execution, the adequacy of disclosure, whether both parties had counsel, and whether the terms produce an unconscionable result.
Frequently Asked Questions
Do I need a lawyer for a prenuptial agreement in New York?
New York does not legally require attorney representation for a valid prenuptial agreement, but having independent counsel for both parties substantially increases enforceability. The January 2025 J.M. v. G.V. decision demonstrated that courts closely scrutinize agreements signed by unrepresented parties, particularly regarding spousal maintenance waivers. Attorney costs typically range from $1,500 to $7,500 per party depending on complexity.
How much does a prenuptial agreement cost in New York?
A prenuptial agreement in New York typically costs between $1,500 and $10,000 total, with simple agreements starting around $1,500 and complex high-net-worth agreements exceeding $20,000. New York City attorneys generally charge higher fees than upstate practitioners. Both parties should have independent counsel, effectively doubling the total legal costs to ensure enforceability.
Can a prenuptial agreement be overturned in New York?
Yes, New York courts can invalidate prenuptial agreements upon proof of fraud, duress, unconscionability, or failure to meet formal requirements under DRL § 236(B)(3). However, the challenging party bears a heavy burden of proof, and courts apply strict scrutiny to invalidation claims. Agreements that are fair on their face will generally be enforced unless clear grounds for invalidation exist.
Does a prenup have to be notarized in New York?
Yes, New York requires prenuptial agreements to be acknowledged before a notary public in the same manner required to record a deed under DRL § 236(B)(3). This deed-style acknowledgment requires the notary to verify each signer's identity and certify that they acknowledged signing the agreement. Failure to complete proper notarization can render the entire agreement unenforceable.
Can a prenuptial agreement waive alimony in New York?
Prenuptial agreements can waive or limit spousal maintenance in New York, but such waivers face heightened judicial scrutiny. Following the 2025 J.M. v. G.V. decision, valid maintenance waivers must include both parties' actual incomes and complete statutory calculations under DRL § 236(B)(6). A waiver cannot leave one spouse eligible for public assistance.
How long before the wedding should we sign a prenuptial agreement?
Couples should begin the prenuptial agreement process at least 3-6 months before the wedding to allow adequate time for drafting, review, negotiation, and independent legal consultation. Agreements signed days before the wedding face heightened scrutiny for duress and may be more vulnerable to invalidation. Starting early demonstrates that both parties had meaningful opportunity to consider the terms.
What happens if we don't have a prenuptial agreement in New York?
Without a prenuptial agreement, New York's equitable distribution laws under DRL § 236(B) govern property division upon divorce. Marital property is divided equitably (not necessarily equally) based on 14 statutory factors, and spousal maintenance is calculated using the statutory formula with an income cap of $241,000 for 2026. Each spouse retains their separate property, but commingling can convert separate property to marital property.
Can a prenuptial agreement address child custody?
Prenuptial agreements may include provisions expressing the parties' wishes regarding child custody, but these provisions are not binding on New York courts. Judges must always decide custody based on the child's best interests at the time of divorce under DRL § 240. Similarly, child support provisions in prenuptial agreements are subject to court modification if they do not meet the child's needs.
Does New York follow the Uniform Premarital Agreement Act?
No, New York has not adopted the Uniform Premarital Agreement Act (UPAA). Instead, New York prenuptial agreement law is governed by DRL § 236(B)(3) and decades of case law interpreting the statute. This means New York has its own unique requirements, including the deed-style acknowledgment standard that differs from UPAA states.
Can I modify a prenuptial agreement after marriage?
Yes, married couples can modify or replace their prenuptial agreement through a written postnuptial agreement that meets the same formal requirements under DRL § 236(B)(3). The modification must be in writing, signed by both parties, and properly acknowledged before a notary. Oral modifications are unenforceable, and both parties must consent to any changes.
