New York couples with real property, business interests, expected inheritances, significant debt, or large income differences can use a prenup to address financial issues before marriage. A prenup can set rules for property, specified debts between the spouses, and maintenance, while child-related terms remain subject to New York law and court review.

As an NYC divorce & family law attorney, he also represents individuals when an existing prenup affects property division, maintenance, or other financial issues in a divorce.

Do I Need a Prenup Before Getting Married in New York?
New York law does not require a prenup before marriage. A couple can choose to use one to set financial terms in advance rather than rely only on New York’s default rules if the marriage later ends.
Common reasons to consider a prenup include ownership of a business or professional practice, a premarital apartment, co-op, or investment property, or plans for one partner to step back from work to raise children. A couple can also address large income differences, estate rights involving children from a prior relationship, and responsibility between the spouses for specified student loan or credit card debt.
Without an agreement, New York’s equitable distribution rules apply. “Equitable” does not mean “equal,” because courts divide marital property after considering statutory factors.
Manhattan prenuptial agreement attorney Richard Roman Shum can review your financial circumstances and explain which property, debt, maintenance, and estate issues a prenup can address before marriage.
What Does a Prenup Cover in a New York Divorce?
New York Domestic Relations Law § 236(B)(3) sets the core requirements for prenuptial agreements. The agreement must be in writing, signed by both parties, and properly acknowledged or proven in the manner required for a deed to be recorded.
What a Prenup Can Address
Property provisions in a premarital agreement can classify assets as separate or marital, including how appreciation in premarital property will be treated. The agreement can also allocate responsibility between the spouses for specified debts, address maintenance, and set terms for jointly owned property.
Estate rights are another issue a prenup can address. For example, a spouse may waive the right of election against the other spouse’s estate under Estates, Powers and Trusts Law § 5-1.1-A.
What a Prenup Cannot Control
Child custody and parenting time may be included in a prenup, but those terms do not bind the court. If a dispute later arises, the court decides custody and parenting time based on the child’s best interests.
Child support provisions may also appear in the agreement, but parents cannot waive a child’s right to support. Any child support provision remains subject to DRL § 240 and the Child Support Standards Act.
Can a Prenup Address Temporary Spousal Support in New York?
A prenup can define, cap, or waive spousal maintenance. It can also waive temporary maintenance while a divorce is pending if the writing clearly shows that the parties intended the waiver to cover temporary support.
When temporary maintenance is not controlled by a valid agreement, the court applies DRL § 236(B)(5-a). As of March 1, 2026, the maintenance payor income cap is $241,000. The statutory formula applies to income up to that cap, while additional maintenance on income above the cap is within the court’s discretion under the statutory factors. Temporary maintenance does not begin automatically because a summons has been served. Relief must be requested and decided by the court unless the parties reach an agreement.
An agreement that addresses only final or post-divorce maintenance may still leave temporary maintenance for the court to decide.
DRL § 236(B)(3) requires maintenance terms to have been fair and reasonable when the agreement was made and not unconscionable when final judgment is entered. General Obligations Law § 5-311 also bars an agreement that would leave a spouse incapable of self-support and likely to become a public charge.
How Can a Prenup Affect Finances When Filing First?
For equitable distribution, marital property includes property either spouse acquires during the marriage before a separation agreement is executed or before a divorce or another action in which equitable distribution is available begins. Property that qualifies as separate under New York law or a valid agreement is excluded. Filing for divorce can therefore set the cutoff for newly acquired marital property.
Consider a spouse who started a consulting business before the marriage. Without an agreement, some appreciation in that business can become marital property if it is tied to the other spouse’s direct or indirect contributions. Resolving that issue can require valuation and tracing evidence. If a valid prenup clearly treats the business and specified appreciation as separate property, the dispute can be narrower, though the court may still need to interpret or enforce the agreement.
A prenup does not eliminate financial disclosure in a contested divorce. When New York’s matrimonial disclosure rules apply, the parties must exchange statements of net worth and specified financial records.
A divorce filing also raises a separate question about where the case can be brought. Under CPLR 515, venue can be based on the county where either spouse lives and, if there are minor children of the marriage, the county where one of those children lives, subject to statutory exceptions. If either spouse or a minor child of the marriage lives in Manhattan, New York County Supreme Court can therefore be a proper venue.
A separation action does not have the same cutoff effect. Filing an action for separation does not stop marital property from continuing to accrue for equitable distribution purposes. A valid prenuptial or postnuptial agreement can set a different property rule if its terms clearly do so.
Key Takeaway: The filing date can affect which property falls within the marital estate, but it does not automatically become the valuation date for each asset. New York courts can select valuation dates from the commencement of the action through trial.
Attorney Richard Roman Shum can review an existing prenup and explain which financial issues it resolves and which still require disclosure, negotiation, or court review after a divorce is filed.

Does a Prenup Reduce Legal Fees and Court Costs?
A prenup does not change the basic court filing fees required for a divorce, but it can narrow disputes over property and maintenance. With fewer issues in dispute, the parties may need less discovery, valuation work, or motion practice, which can lower attorney and expert fees.
A dispute over whether an account is separate or marital can require financial records, tracing analysis, or depositions. Valuing a closely held business can also involve a valuation professional, and each party can retain a separate professional when the value is disputed. If the agreement is later challenged, litigation over its validity or interpretation can add legal fees.
What Questions Should I Ask Before Signing a Prenup?
Before signing a prenup, couples should look beyond the final financial terms and consider how the agreement was prepared and what its provisions will mean in practice. These questions highlight issues worth reviewing before the agreement is finalized:
| Question to Ask |
Why It Matters |
| Has each party provided accurate financial information? |
Concealment or misrepresentation can support a challenge based on fraud or overreaching. Incomplete disclosure alone does not automatically invalidate a prenup. |
| Does each party have separate counsel? |
Separate lawyers are not required in New York, but independent legal advice can reduce disputes over whether a party understood the agreement or had a fair opportunity to review it. |
| How will appreciation and commingled funds be handled? |
The agreement can define how increases in the value of separate property and separate funds placed in a joint account will be classified. |
| Are there sunset or review provisions? |
These optional terms can change or call for review of the agreement after a specified period or event. |
A duly executed prenuptial agreement carries a strong presumption of validity in New York. A party seeking to set one aside bears a high burden to prove fraud, duress, overreaching resulting in manifest unfairness, or other inequitable conduct. Courts can examine both the agreement and the circumstances surrounding its execution when evaluating a challenge.
When Should New York Couples Consult a Prenup Attorney?
It is helpful to start early enough for financial disclosure, negotiation, drafting, and legal review before wedding pressure builds. New York law does not impose a set waiting period, but a rushed signing process can become part of a later claim of duress or overreaching depending on the facts.
Recent polling also shows increased prenup use among younger adults. A 2026 Harris Poll found that 53% of engaged or married Gen Z and millennial adults had signed a prenup, up from 41% of Gen Z and 34% of millennials in a comparable 2022 poll.
If the couple is already married, a postnuptial agreement can still address many property and maintenance issues. Postnuptial agreements must meet the requirements of DRL § 236(B)(3) and receive closer judicial scrutiny because they are made between spouses. A business launch, property purchase, or major financial change can be a practical time to consider one.

Frequently Asked Questions
What is the difference between a prenup and a postnuptial agreement?
The main difference is timing: a prenuptial agreement is signed before marriage, while a postnuptial agreement is made after the couple is married. Both must meet New York’s legal requirements, but courts scrutinize postnuptial agreements more closely because they are agreements between spouses.
Is a prenup enforceable in New York?
A properly executed prenup is presumed valid in New York, but it can still be challenged based on fraud, duress, overreaching resulting in manifest unfairness, unconscionability, or other inequitable conduct.
What happens if I don’t have a prenup and my spouse files for divorce first?
New York’s equitable distribution rules apply unless another valid agreement controls. Filing for divorce can set the cutoff for newly acquired marital property, but it does not automatically determine how individual assets will be valued or divided.
Can a prenup limit spousal maintenance under New York law?
A prenup can define, cap, or waive maintenance, including temporary maintenance if the agreement clearly covers it. Maintenance terms must meet New York’s fairness requirements and cannot leave a spouse incapable of self-support and likely to become a public charge.
Does a prenup need to be signed and notarized in New York?
Not necessarily before a notary. The agreement must be in writing, signed by both parties, and properly acknowledged or proven under DRL § 236(B)(3); a premarital agreement can also be acknowledged before certain people authorized to solemnize a marriage.
Can a prenup be challenged after both parties have signed it?
A prenup can be challenged for fraud, duress, overreaching resulting in manifest unfairness, unconscionability, or improper execution. Incomplete financial disclosure, lack of separate counsel, or signing close to the wedding can matter, but none of those facts alone automatically invalidates the agreement.
How much does it cost to draft a prenup in New York?
Cost depends on the assets involved and how much drafting and negotiation are required. New York does not require each party to have separate counsel, but if both retain lawyers, each side will have its own legal fees.
