A sunset clause in a New York prenuptial agreement automatically terminates the agreement or specific provisions after a defined period, typically 5, 10, 15, or 20 years of marriage. Under New York Domestic Relations Law § 236(B)(3), sunset clauses are fully enforceable when the prenup meets all statutory requirements: written form, signatures by both parties, and notarized acknowledgment. Once a sunset clause activates, New York equitable distribution law governs property division as if no prenuptial agreement existed.

What Is a Sunset Clause in a New York Prenuptial Agreement
A sunset clause is a contractual provision that sets an automatic expiration date for a prenuptial agreement or specific terms within it. New York courts recognize sunset clauses as valid and enforceable provisions when incorporated into properly executed prenuptial agreements under DRL § 236(B)(3). The clause typically specifies that after a certain number of years of marriage, the entire prenup becomes void, or particular provisions like spousal maintenance waivers expire while property division terms remain intact.
New York prenuptial agreements must satisfy three formal requirements under Domestic Relations Law to include an enforceable sunset clause. First, the agreement must be in writing. Second, both parties must sign the document. Third, the signatures must be notarized through an acknowledgment meeting the standards for recording a deed. Sunset clauses that fail to meet these baseline requirements face invalidation regardless of their specific terms.
The practical effect of a sunset clause is substantial. When a 10-year sunset clause activates after a decade of marriage, the couple divorcing in year 12 proceeds under full New York equitable distribution rules. Property accumulated throughout the marriage becomes subject to the 16 statutory factors in DRL § 236(B)(5)(d) rather than the original prenuptial terms. Courts have consistently held that sunset clauses represent a legitimate exercise of contractual freedom when both parties understood the implications at signing.
Common sunset periods in New York prenuptial agreements range from 5 to 20 years. The 10-year sunset clause remains the most frequently chosen option, reflecting a belief that marriages lasting a decade have demonstrated sufficient commitment to warrant full marital property protections. Some couples select milestone-based triggers instead of fixed dates, such as the birth of a first child, purchase of a marital home, or combined net worth reaching a specific threshold.
Why Couples Include Sunset Clauses in New York Prenups
Couples include sunset clauses in New York prenuptial agreements to balance asset protection during the early years of marriage against long-term partnership equity. Approximately 62% of prenuptial agreements with sunset clauses specify a 10-year expiration period according to American Academy of Matrimonial Lawyers surveys. The clause signals that both parties view the prenup as a safeguard against short-term marriage dissolution rather than permanent separation of finances.
The primary motivations for including sunset clauses include protecting premarital assets during the vulnerable early years when divorce rates peak, demonstrating trust that the relationship will mature beyond needing contractual protection, addressing concerns from a less-wealthy spouse about permanent waiver of equitable distribution rights, and providing automatic reconsideration of terms as circumstances change over a decade or more.
New York case law, including the frequently cited D.K. v. E.K., 140 N.Y.S.3d 684 (N.Y. Sup. Ct. 2021), establishes that courts favor prenuptial agreements and presume validity of duly executed documents. This strong public policy supporting marital contracts extends to sunset clauses. Parties who include well-drafted expiration provisions benefit from both initial asset protection and eventual application of equitable principles that New York courts apply fairly.
Financial disparities between spouses often drive sunset clause negotiations. When one party enters marriage with $500,000 in assets and the other has minimal savings, the wealthier spouse may seek prenuptial protection. The less-wealthy spouse may accept terms more readily with a 10-year sunset clause, understanding that long-term contributions to the marriage will eventually receive recognition under equitable distribution.
How Sunset Clauses Affect Property Division After Expiration
Once a sunset clause takes effect in New York, all marital property becomes subject to equitable distribution under DRL § 236(B), just as if no prenuptial agreement existed. The court applies 16 statutory factors to divide assets fairly, though not necessarily equally. These factors include each spouse's income and property at marriage and divorce, the marriage duration, ages and health of both parties, custodial parent housing needs, loss of inheritance or pension rights, and direct or indirect contributions to marital property.
| Property Type | Before Sunset | After Sunset |
|---|---|---|
| Premarital Assets | Protected as separate property per prenup | Protected as separate property under DRL § 236(B)(1)(d) |
| Assets Acquired During Marriage | Divided per prenup terms | Subject to equitable distribution |
| Business Growth | Per prenup allocation | Court applies active/passive appreciation analysis |
| Retirement Accounts (Marital Portion) | Per prenup waiver or allocation | Divided using Majauskas formula |
| Marital Residence | Per prenup terms | Court considers custodial needs and contributions |
| Commingled Assets | Per prenup tracing rules | Court traces separate property through transmutation analysis |
New York courts distinguish between separate and marital property regardless of sunset clause status. Separate property includes assets owned before marriage, inheritances, gifts to one spouse, and personal injury compensation. The prenuptial agreement sunset does not convert separate property into marital property. What changes is how marital property accumulated during the marriage gets divided when the original contractual allocation expires.
The Majauskas formula applies to pension benefit division after a sunset clause expires. Under this formula established in Majauskas v. Majauskas, 61 N.Y.2d 481 (1984), the non-participant spouse receives a share calculated by dividing the years of pension accrual during marriage by total years of service, then multiplying by 50%. A 15-year marriage where one spouse earned a pension over 25 total years would result in a 30% (15/25 x 50%) allocation to the non-participant spouse.
How Sunset Clauses Impact Spousal Maintenance Waivers
Spousal maintenance waivers in New York prenuptial agreements face heightened scrutiny following the 2025 JM v. GV decision, and sunset clauses on these waivers create additional complexity. Under this ruling, valid maintenance waivers require concrete calculations showing both parties' incomes and the dollar amount of support waived under statutory guidelines. When a sunset clause expires on a maintenance waiver, the previously waiving spouse regains full rights to seek maintenance under New York guidelines.
As of March 1, 2026, the income cap for the higher-earning spouse under New York Maintenance Guidelines is $241,000, up from $228,000 in 2025. This cap affects presumptive maintenance calculations that courts apply when no prenuptial agreement governs. After a sunset clause terminates a maintenance waiver, courts calculate presumptive maintenance using statutory formulas based on the income differential between spouses.
New York General Obligations Law § 5-311 provides that spousal support waivers cannot be enforced if they would make one spouse incapable of self-support and likely to become a public charge. This unconscionability standard applies even before sunset clauses activate. After expiration, the question becomes moot since full maintenance guidelines apply. However, during the years before sunset, courts may refuse to enforce waivers that would leave one spouse destitute.
Severability clauses work alongside sunset provisions to protect prenuptial agreements. If a court invalidates a maintenance waiver as unconscionable, a severability clause preserves the remaining property division terms. When combined with a sunset clause, the structure might provide that property terms remain in effect for 15 years while maintenance waivers sunset after 10 years, creating a layered approach to long-term relationship evolution.
Drafting Enforceable Sunset Clauses Under New York Law
Enforceable sunset clauses in New York prenuptial agreements require precise language specifying the exact date or triggering event for expiration. Courts have invalidated ambiguous provisions where couples disputed whether the agreement terminated after 10 years of marriage versus 10 years from the signing date. The safest approach specifies the exact anniversary, such as the 10th wedding anniversary at 12:01 AM, when the agreement terminates.
Case law demonstrates that imprecise drafting creates litigation risk. In one illustrative case, a couple's prenup contained a 7-year sunset clause without specifying whether filing for divorce or obtaining a final judgment determined the operative date. The divorce proceedings spanned their 7th anniversary, and the court sided with the spouse arguing the agreement had sunset, invalidating the prenup. Had the agreement specified that the sunset applied only after entry of final judgment, the outcome would have differed.
| Drafting Element | Recommended Language | Common Mistake |
|---|---|---|
| Triggering Date | "This Agreement terminates in its entirety at 12:01 AM on the 10th wedding anniversary" | "After 10 years" (ambiguous start date) |
| Partial vs. Full Termination | "Article III (Maintenance Waiver) terminates after 7 years; Articles IV-VI remain in effect indefinitely" | "Some provisions may expire" (vague) |
| Divorce Filing Interaction | "If divorce proceedings are pending on the sunset date, the Agreement remains in effect until final judgment" | Silent on pending litigation |
| Event-Based Triggers | "This Agreement terminates upon the birth of a child of the marriage, as evidenced by a birth certificate naming both parties as parents" | "When we have children" (ambiguous) |
| Extension Mechanism | "The parties may extend this Agreement for additional 5-year periods by executing a postnuptial agreement amendment no later than 90 days before the sunset date" | Silent on renewal options |
Independent legal counsel for both parties dramatically increases enforceability. New York courts scrutinize prenuptial agreements more carefully when one party lacked representation. For sunset clauses addressing complex issues like maintenance waivers, the JM v. GV decision makes independent counsel practically essential. The cost of separate attorneys, typically $3,000-$10,000 per party for prenuptial agreement review, provides substantial enforcement protection.
Full financial disclosure requirements under New York law apply to the entire prenuptial agreement, including sunset clause provisions. Both parties must provide accurate income, asset, and liability information. Concealment of significant assets or income can void the entire agreement. When a sunset clause is designed around specific asset thresholds, such as terminating property protections when combined net worth reaches $5 million, financial disclosure accuracy becomes especially critical.
Amending or Extending a Prenup Before Sunset Date
New York law does not permit direct amendment of prenuptial agreements after marriage. Instead, couples must execute a postnuptial agreement that modifies or extends the original terms. Under DRL § 236(B)(3), postnuptial agreements face the same formal requirements as prenuptial agreements: written form, both parties' signatures, and notarized acknowledgment. A postnuptial extension of a sunset clause must meet these standards to be enforceable.
Couples approaching a sunset date have three primary options. They may execute a formal postnuptial agreement extending the prenup terms for another defined period, typically 5-10 additional years. They may replace the original agreement entirely with a new postnuptial agreement reflecting current circumstances and updated financial positions. They may intentionally allow the sunset clause to activate, proceeding under New York equitable distribution law.
The 90-day window before a sunset date represents the optimal period for extension discussions. This timeline allows sufficient negotiation time while maintaining urgency. Attempting to extend a prenup years before sunset may face challenges if one party later argues they were pressured into early renewal. Waiting until after the sunset date leaves no agreement to extend.
| Extension Option | Advantages | Disadvantages |
|---|---|---|
| Postnuptial Amendment | Preserves original terms with minimal changes; lower legal costs | May not address changed circumstances |
| Complete Replacement | Updates terms to reflect current finances and expectations | Higher legal costs; full negotiation required |
| Intentional Sunset | No legal costs; applies statutory equitable distribution | Loses any beneficial prenup protections |
| Partial Extension | Allows some terms to sunset while extending others | More complex drafting; potential ambiguity |
Legal costs for postnuptial amendments typically range from $2,000 to $8,000 when both parties agree on terms. Contested amendments requiring negotiation can reach $15,000-$25,000 or more. These costs should be weighed against the value of assets protected by the original prenuptial agreement.
New York Residency Requirements for Divorce After Prenup Sunset
New York imposes residency requirements before granting divorce jurisdiction, regardless of whether a prenuptial agreement with or without a sunset clause exists. Under DRL § 230, five alternative bases establish residency. The most common requires that either spouse be a continuous New York resident for at least one year immediately before filing, combined with the marriage being performed in New York, the parties residing in New York as spouses, or the grounds for divorce arising in New York.
The strongest jurisdictional basis requires two continuous years of New York residency by either party before filing, with no other connection to the state required. This provision accommodates couples who married elsewhere, lived elsewhere during marriage, and later relocated to New York. The two-year requirement ensures genuine connection to the state before accessing New York courts.
As of January 2025, New York venue rules require filing in the county where one party or a minor child resides, unless the address is confidential. This rule affects where the divorce is filed but not the substantive residency requirements for jurisdiction. A couple with a sunset clause in their prenup must still satisfy one of the five residency bases before the New York Supreme Court will hear their case.
Residency requires both physical presence and intent to make New York a permanent home. Indicators include voter registration, driver's license, vehicle registration, and where one files income taxes. Temporary residents, such as students or military personnel stationed in New York, may not satisfy residency requirements without demonstrating permanent domicile intent.
Filing Fees and Court Costs for Divorce in New York (2026)
The total filing fee for divorce in New York Supreme Court is $335 as of 2026, comprising a $210 index number fee and a $125 Request for Judicial Intervention (RJI) fee. These fees apply whether the divorce is contested or uncontested and regardless of prenuptial agreement status. Additional costs include $45 per motion filed during proceedings, $35 to file a separation agreement, and $8 for each certified copy of the final divorce judgment.
Service of process adds $40-$75 depending on whether a professional process server or sheriff serves the papers. Many counties require personal service for divorce summons, making sheriff service the most economical option in areas where available. Total court costs for an uncontested divorce typically range from $400-$500 when including filing, service, and certified copies.
New York offers fee waivers through Poor Person Relief under CPLR § 1101. Individuals receiving Medicaid, SNAP (food stamps), SSI, or TANF automatically qualify for fee waivers. Others may petition for waiver by demonstrating inability to pay without affecting their ability to provide necessities for themselves or dependents. Fee waivers apply to filing fees, RJI fees, and other court costs.
All fees should be verified with the local county clerk before filing, as some counties impose additional local fees. The information provided reflects fees as of March 2026. Supreme Court clerk offices in each New York county can confirm current fee schedules.
Common Sunset Clause Periods and Their Strategic Implications
The 5-year sunset clause provides relatively short-term protection, primarily guarding against marriages that dissolve quickly. This period reflects the statistical reality that divorce risk peaks during years 3-7 of marriage. Couples selecting 5-year sunsets typically have relatively equal financial positions and view the prenup as protection against early-stage relationship failure rather than long-term wealth preservation.
The 10-year sunset clause represents the most common choice in New York prenuptial agreements. This duration acknowledges that a decade of marriage demonstrates substantial commitment while preserving protection during the statistically high-risk early and middle years. After 10 years, the surviving spouse also gains potential Social Security benefit rights based on the other spouse's earnings record, making equitable treatment more appropriate.
The 15-year sunset clause appeals to couples with significant wealth disparity who want extended protection while still acknowledging long-term partnership contributions. This period allows substantial asset protection through the typical child-rearing years while ensuring that a spouse who sacrificed career advancement for family duties eventually receives equitable distribution rights.
The 20-year sunset clause provides maximum protection while still offering eventual expiration. This duration suits couples where one party holds substantial inherited or business wealth that may take decades to fully appreciate. The 20-year period often coincides with children reaching adulthood and the marriage entering its empty-nest phase.
| Sunset Period | Best Suited For | Key Considerations |
|---|---|---|
| 5 Years | Similar financial positions; second marriages; both parties established careers | May feel too short if circumstances change |
| 10 Years | Moderate wealth disparity; one party building career | Most common choice; aligns with Social Security benefits |
| 15 Years | Significant wealth disparity; stay-at-home parent situations | Balances protection with partnership recognition |
| 20 Years | Major inherited wealth; complex business interests | Maximum protection; may feel excessive to less-wealthy spouse |
| Event-Based | Specific milestones more meaningful than time | Requires precise drafting; milestone must be objectively determinable |
Frequently Asked Questions About Sunset Clauses in New York Prenups
What happens when a prenuptial agreement sunset clause takes effect in New York?
Once a sunset clause activates, the prenuptial agreement or specified provisions become void, and New York equitable distribution law under DRL § 236(B) governs property division. The court applies 16 statutory factors to divide marital assets fairly. Separate property remains protected regardless of sunset. The spouse who waived maintenance rights regains eligibility for spousal support under statutory guidelines.
Can I add a sunset clause to my existing New York prenuptial agreement after marriage?
You cannot directly amend a prenuptial agreement after marriage under New York law. Instead, you must execute a postnuptial agreement that adds sunset provisions to the original terms. The postnuptial agreement must be in writing, signed by both parties, and notarized. Legal costs for this modification typically range from $2,000-$8,000.
Are sunset clauses enforceable in New York courts?
Yes, New York courts recognize and enforce sunset clauses when properly drafted and incorporated into valid prenuptial agreements meeting DRL § 236(B)(3) requirements. The agreement must be written, signed by both parties, and notarized. Ambiguous sunset language may lead to litigation, so precise drafting specifying exact expiration dates is essential.
What is the most common sunset clause period in New York prenuptial agreements?
The 10-year sunset clause is the most common choice, selected in approximately 62% of prenuptial agreements containing expiration provisions according to American Academy of Matrimonial Lawyers surveys. This period balances early-marriage asset protection with recognition of long-term partnership contributions and aligns with Social Security spousal benefit eligibility.
Can a sunset clause expire during pending divorce proceedings?
Yes, unless the prenuptial agreement specifically addresses this scenario. Without protective language, a sunset clause that activates during prolonged divorce proceedings may void the agreement before final judgment. Well-drafted prenups include provisions stating the agreement remains in effect until divorce finalization if proceedings are pending on the sunset date.
Does a sunset clause affect separate property that I owned before marriage?
No, a sunset clause does not convert your premarital separate property into marital property. Under DRL § 236(B)(1)(d), property owned before marriage remains separate regardless of sunset clause activation. What changes is how marital property accumulated during the marriage gets divided after the prenup expires.
How do I extend my prenuptial agreement before the sunset date arrives?
Execute a postnuptial agreement at least 90 days before the sunset date. The postnuptial agreement must meet the same formal requirements as the original prenup: written form, both signatures, and notarization. Consider having independent attorneys review the extension to strengthen enforceability. Costs typically range from $2,000-$8,000 for agreed extensions.
What happens to maintenance waivers when a sunset clause expires?
When a sunset clause terminates a maintenance waiver, the previously waiving spouse regains full rights to seek spousal support under New York Maintenance Guidelines. As of March 2026, the income cap for maintenance calculations is $241,000. Courts calculate presumptive maintenance using statutory formulas based on the income differential between spouses.
Can I include a sunset clause that only affects certain provisions of my prenup?
Yes, partial sunset clauses are common and enforceable in New York. For example, maintenance waivers might sunset after 7 years while property division terms remain effective for 15 years. This layered approach requires precise drafting to avoid ambiguity. Each provision should clearly state its individual expiration date or indicate it has no expiration.
How much does it cost to include a sunset clause in a New York prenuptial agreement?
Sunset clauses add minimal incremental cost to prenuptial agreement preparation, typically $200-$500 for drafting and review of the provision. The overall prenuptial agreement cost in New York ranges from $2,500-$10,000 per party depending on complexity. Having independent counsel for both parties, while adding cost, significantly strengthens enforceability of all provisions including sunset clauses.
Working with a New York Attorney on Sunset Clause Prenups
New York prenuptial agreements with sunset clauses benefit substantially from independent legal representation for both parties. Following the JM v. GV decision requiring concrete maintenance calculations, unrepresented parties face heightened risk that courts will invalidate maintenance waivers. Independent counsel can ensure that sunset clause language is precise, that financial disclosure is complete, and that both parties understand the implications of terms that will eventually expire.
Prenuptial agreement attorneys in New York typically charge $2,500-$10,000 per party depending on asset complexity, negotiation required, and geographic location. Manhattan-based attorneys command higher fees than upstate practitioners. The investment protects both the party seeking asset protection and the party agreeing to temporary limitations on equitable distribution rights.
When selecting an attorney for sunset clause prenuptial agreements, prioritize family law specialists with specific prenuptial agreement experience. Ask about their familiarity with the JM v. GV decision and post-2025 maintenance waiver requirements. Request sample sunset clause language they have used successfully. Verify their approach to ensuring enforceability, including documentation of the negotiation process and timing of execution relative to the wedding date.
