What Should Be in a Prenup in New York? Complete 2026 Checklist

A valid New York prenuptial agreement must include 12 essential elements under DRL §236(B)(3): property classification, maintenance waivers with actual calculations, inheritance provisions, debt allocation, business ownership terms, sunset clauses, and full financial disclosure schedules. As of March 1, 2026, maintenance waivers must reference the $241,000 income cap and include page-by-page acknowledgments following the JM v. GV ruling. The average New York prenup costs $2,500 to $10,000 for attorney drafting and negotiation, with high-net-worth agreements exceeding $25,000. Without a properly executed prenup, New York courts apply equitable distribution rules under DRL §236(B)(5), dividing marital property based on 13 statutory factors rather than a 50/50 split.

This comprehensive guide covers what to include in a prenup in New York, the specific statutory requirements for enforceability, and the 2026 updates that affect maintenance waivers and property division clauses.

Essential Elements Every New York Prenup Must Include

A complete New York prenuptial agreement requires 12 core elements to be enforceable: written format with notarized signatures, full financial disclosure attachments, property classification provisions, maintenance terms with concrete calculations, inheritance waivers, debt allocation, business ownership protections, sunset clause considerations, lifestyle provisions, dispute resolution mechanisms, severability language, and independent counsel acknowledgments. Under DRL §236(B)(3), the agreement must be subscribed by both parties and acknowledged in the manner required to entitle a deed to be recorded. Missing any of these elements provides grounds for invalidation under the Christian v. Christian standard established by the Court of Appeals in 42 N.Y.2d 63 (1977).

The 2025 JM v. GV decision from Justice Jeffrey S. Sunshine added a critical requirement: maintenance waivers must now include actual income figures, application of the DRL §236(B)(6) formula with concrete calculations, and page-by-page acknowledgment that each spouse understands the specific dollar amount being waived.

The 12 Core Prenup Clauses

1. Property classification (separate vs. marital)
2. Full financial disclosure schedules
3. Maintenance/spousal support terms
4. Inheritance and estate planning provisions
5. Debt allocation and protection
6. Business ownership and appreciation
7. Real estate provisions (marital home)
8. Retirement account treatment
9. Sunset clause terms (optional)
10. Dispute resolution mechanisms
11. Severability provisions
12. Independent counsel acknowledgments

Property Classification: Separate vs. Marital Assets

New York prenuptial agreements can override the default property classification rules under DRL §236(B)(1), allowing couples to designate assets acquired during marriage as separate property or convert separate property into marital property. Without a prenup, New York applies equitable distribution to all marital property, meaning a judge divides assets based on 13 statutory factors rather than a guaranteed 50/50 split. Separate property under DRL §236(B)(1)(d) includes assets owned before marriage, inheritances, gifts from third parties, and personal injury compensation—but only if kept segregated from marital funds.

The most common property provisions in New York prenups address:

Assets to Classify as Separate Property

• Pre-marital bank accounts and investments
• Real estate owned before marriage
• Business interests established before the wedding
• Expected inheritances from family members
• Stock options granted before marriage
• Intellectual property and royalty streams
• Art collections, jewelry, and collectibles

Commingling and Transmutation Risks

Commingling occurs when separate property funds are deposited into joint accounts, causing the separate property to lose its character under New York law. Transmutation refers to intentionally converting separate property into marital property through retitling or written agreement. A prenup can establish protective measures: separate account maintenance requirements, documentation protocols for tracing separate funds, and express statements that commingling does not convert separate property into marital property.

Spousal Maintenance Provisions: 2026 Requirements

New York prenups can establish spousal maintenance terms or waive maintenance entirely, but the 2025 JM v. GV ruling requires specific calculations using the DRL §236(B)(5-a) guideline formula. As of March 1, 2026, the maintenance payor income cap increased from $228,000 to $241,000, meaning the formula applies only to income up to this threshold with courts having discretion on amounts above. A maintenance waiver that would leave one spouse unable to meet basic needs and likely to require public assistance will not be enforced under New York's unconscionability doctrine.

Valid Maintenance Waiver Requirements (Post-JM v. GV)

Following the 2025 JM v. GV decision, valid maintenance waivers must include:

1. Each spouse's actual current income
2. Application of the DRL §236(B)(5-a) formula using those incomes
3. The specific dollar amount being waived (monthly and total)
4. Duration of support that would otherwise apply
5. Written acknowledgment by each party
6. Page-by-page initials confirming understanding

The New York Maintenance Formula

The guideline formula under DRL §236(B)(5-a) calculates maintenance as follows:

• Where the maintenance payor is also the child support payor: The lesser of (a) 30% of payor's income minus 20% of payee's income, or (b) 40% of combined income minus payee's income
• Where no child support or payee is child support payor: The lesser of (a) 20% of payor's income minus 25% of payee's income, or (b) 40% of combined income minus payee's income

Duration guidelines range from 15% of the marriage length for marriages up to 15 years to 30-50% for marriages over 20 years.

Inheritance and Estate Planning Provisions

A New York prenup should address inheritance rights, elective share waivers, and estate planning coordination to prevent conflicts between the prenuptial agreement and each spouse's estate plan. Under New York Estates, Powers and Trusts Law (EPTL) §5-1.1-A, a surviving spouse is entitled to an elective share of the deceased spouse's estate—typically one-third to one-half of the net estate. A prenup can waive this elective share right, allowing each spouse to leave their assets to children from prior relationships or other beneficiaries.

Key Inheritance Provisions to Include

• Elective share waivers (right to inherit portion of estate)
• Testamentary provision requirements (promises to include spouse in will)
• Life insurance beneficiary designations
• Trust beneficiary considerations
• Treatment of inherited assets received during marriage
• Revocation provisions upon divorce filing

Protecting Family Wealth

For spouses with significant family wealth or expected inheritances, prenups typically include:

1. Acknowledgment that inherited assets remain separate property
2. Protection against transmutation through commingling
3. Appreciation on inherited assets remains separate
4. No claim to spouse's family business interests
5. Waiver of spousal rights in family trusts

Debt Allocation and Protection Clauses

New York prenuptial agreements should explicitly address debt responsibility, distinguishing between pre-marital debts, debts incurred individually during marriage, and joint marital debts. Under equitable distribution principles, courts may assign debt responsibility based on which spouse incurred the debt, which spouse benefited from the debt, and each spouse's ability to pay. A prenup can override these discretionary factors with specific allocation terms.

Common Debt Provisions

• Pre-marital debt remains sole responsibility of debtor spouse
• Student loan debt incurred during marriage stays with degree-holder
• Credit card debt responsibility follows account holder
• Mortgage debt allocation upon divorce
• Business debt protection for non-owner spouse
• Indemnification clauses for debt assigned to one spouse

Business Ownership and Appreciation

Business interests require detailed treatment in New York prenups because appreciation on a separate property business may become marital property if the owner-spouse's active efforts during the marriage contributed to that appreciation. Under DRL §236(B)(5), the non-owner spouse may claim an equitable share of the marital portion of appreciation. A comprehensive prenup addresses both the initial business valuation and the methodology for calculating any marital appreciation.

Business Protection Provisions

Effective business clauses in New York prenups include:

1. Current business valuation attached as exhibit
2. Agreement that business remains separate property
3. All appreciation remains separate (active and passive)
4. Waiver of any claim to goodwill or enterprise value
5. Buy-out terms if business value must be divided
6. Non-owner spouse cannot participate in management
7. Protection from business debts for non-owner spouse
8. Methodology for future valuations if dispute arises

Professional Practice Considerations

For attorneys, physicians, accountants, and other professionals, prenups should address:

• License and degree remain separate property
• Enhanced earning capacity is not divisible
• Practice goodwill belongs to practitioner spouse
• Client/patient relationships are non-transferable assets

Real Estate and Marital Home Provisions

The marital home often represents a couple's largest asset, requiring specific prenup provisions addressing ownership, buyout rights, exclusive occupancy, and sale terms. New York prenups can designate whether a home purchased during marriage with one spouse's separate funds remains separate property or converts to marital property. The agreement should also address homes owned before marriage that become the marital residence.

Real Estate Clauses to Include

• Pre-marital home ownership confirmed as separate property
• Home purchased during marriage: title and source of funds
• Buyout rights and valuation methodology
• Exclusive occupancy during divorce proceedings
• Timeline for sale if neither party can afford buyout
• Mortgage responsibility during separation
• Down payment reimbursement provisions
• Improvements: contribution tracking and reimbursement

Retirement Accounts and QDRO Considerations

Retirement account contributions made during marriage are presumptively marital property under New York law, subject to equitable distribution via Qualified Domestic Relations Orders (QDROs). Prenups can designate retirement contributions as separate property or establish alternative division terms. As of 2026, the average 401(k) balance at retirement age is approximately $232,000, making retirement provisions significant in divorce outcomes.

Retirement Provisions to Address

• Pre-marital retirement balances confirmed separate
• Contributions during marriage: separate or marital treatment
• Employer matching: separate or marital
• Growth and appreciation treatment
• Pension benefits: defined benefit plan considerations
• Social Security benefits (note: cannot be divided by prenup)
• Military retirement (governed by federal law)

Sunset Clauses: When Prenups Expire

New York permits sunset clauses that terminate a prenuptial agreement or specific provisions after a specified period or triggering event. Common sunset periods range from 5 to 20 years, with 10 years being the most frequent choice among New York couples. When a sunset clause activates, the expired provisions no longer apply, and state equitable distribution law governs instead. Carefully drafted sunset clauses specify which provisions expire and which survive indefinitely.

Sunset Clause Options

1. Full agreement sunset (entire prenup expires)
2. Partial sunset (specific provisions expire)
3. Time-based triggers (after 10 years of marriage)
4. Event-based triggers (birth of first child)
5. Milestone-based triggers (home purchase together)
6. Gradual modification (terms change at intervals)

What Typically Survives a Sunset

• Inheritance waivers often remain in effect
• Business ownership protections may continue
• Pre-marital property classifications usually survive
• Debt indemnification provisions persist

Lifestyle and Infidelity Clauses

While New York permits no-fault divorce under DRL §170(7), prenuptial agreements can include lifestyle provisions addressing behavior during the marriage. New York courts have generally enforced reasonable lifestyle clauses, though provisions perceived as unconscionable or contrary to public policy may be invalidated. Infidelity clauses linking adultery to financial consequences have mixed enforceability depending on their specific terms.

Common Lifestyle Provisions

• Geographic restrictions (agree not to relocate without consent)
• Career provisions (support for career changes)
• Religious practice agreements
• Family holiday arrangements
• Parenting philosophy statements (advisory only—not binding on custody)
• Pet ownership and responsibility
• Social media and privacy expectations

Infidelity Clause Considerations

New York courts scrutinize infidelity clauses carefully:

• Financial penalty provisions are more likely enforceable
• Punitive provisions may be deemed unconscionable
• Must define adultery clearly (physical vs. emotional)
• Burden of proof provisions should be included
• Consider discovery and privacy implications

Financial Disclosure Requirements

Full financial disclosure is a prerequisite for prenup enforceability in New York, with hidden assets or incomplete disclosure providing grounds for invalidation. Attached schedules should list all assets, debts, income sources, and expected inheritances. Recent case law emphasizes that general acknowledgments of financial knowledge are insufficient—specific, documented disclosure is required.

Disclosure Schedule Contents

1. All bank and investment accounts with balances
2. Real estate holdings with approximate values
3. Business ownership interests with valuations
4. Retirement accounts with current balances
5. Life insurance policies with death benefits
6. Outstanding debts with balances and creditors
7. Annual income from all sources
8. Expected inheritances or trusts
9. Stock options and deferred compensation
10. Valuable personal property (art, jewelry, vehicles)

Dispute Resolution and Severability

New York prenups should include dispute resolution mechanisms (mediation before litigation) and severability clauses ensuring that if one provision is invalidated, the remainder of the agreement survives. Without severability language, a court finding one unconscionable provision could void the entire prenuptial agreement.

Dispute Resolution Options

• Mandatory mediation before litigation
• Arbitration provisions (binding or non-binding)
• Choice of forum (which county's courts)
• Choice of law (New York law governs)
• Attorney fee provisions (prevailing party)

Severability Language Example

If any provision of this Agreement is held invalid or unenforceable, such invalidity shall not affect other provisions that can be given effect without the invalid provision, and to this end the provisions of this Agreement are severable.

What Cannot Be Included in a New York Prenup

New York prenuptial agreements cannot bind courts on child-related issues or include provisions against public policy. Any clauses attempting to predetermine child custody, visitation, or support amounts are void and unenforceable. Courts must decide these issues at the time of separation based on the child's best interests under DRL §240(1).

Void Provisions Under New York Law

1. Child custody arrangements (courts decide based on best interests)
2. Child support amounts (must follow Child Support Standards Act)
3. Visitation schedules (subject to court modification)
4. Provisions encouraging divorce
5. Illegal activity requirements
6. Provisions requiring personal services as condition of support
7. Waiver of right to seek child support on behalf of children
8. Unconscionable terms that would leave spouse destitute

Frequently Asked Questions About New York Prenups

How much does a prenup cost in New York?

A New York prenuptial agreement typically costs $2,500 to $10,000 for drafting and negotiation, with each spouse needing their own attorney. Complex agreements involving business interests, multiple properties, or high net worth can exceed $25,000 per party. Mediated prenups may reduce costs to $3,000-$5,000 total.

Can I waive spousal support (alimony) in a New York prenup?

Yes, New York permits spousal maintenance waivers in prenuptial agreements, but the waiver must include concrete calculations using each spouse's actual income and the DRL §236(B)(5-a) formula. Following the 2025 JM v. GV ruling, general waivers without specific dollar amounts are unenforceable. The waiver cannot leave one spouse unable to meet basic needs.

How far in advance should we sign the prenup before the wedding?

New York courts recommend signing the prenuptial agreement at least 30-60 days before the wedding to avoid presumptions of duress. Presenting a prenup days before the ceremony creates a rebuttable presumption of coercion, though courts evaluate the totality of circumstances including sophistication of the parties and access to counsel.

Does my spouse need their own attorney for the prenup to be valid?

Independent legal representation is strongly recommended but not strictly required under New York law. However, if one spouse does not have independent counsel, courts will scrutinize the agreement more closely for fairness and may decline to enforce provisions that disadvantage the unrepresented party. Written waiver of representation is required if counsel is declined.

Can a prenup protect my business from my spouse's claims?

Yes, New York prenuptial agreements can protect business interests by designating the business as separate property, waiving claims to appreciation (both active and passive), establishing valuation methodologies, and including indemnification from business debts. Without a prenup, the marital portion of business appreciation may be subject to equitable distribution.

What happens if we don't have a prenup in New York?

Without a prenuptial agreement, New York applies equitable distribution under DRL §236(B)(5), dividing marital property based on 13 statutory factors including marriage duration, income disparity, and contributions to the marriage. Equitable does not mean equal—courts have discretion to divide assets 60/40, 70/30, or other proportions based on circumstances.

Can we modify our prenup after marriage?

Yes, New York permits postnuptial agreements modifying prenuptial terms, provided the modification meets the same formal requirements (written, signed, notarized). Both spouses must consent to modifications, and full financial disclosure must be updated. Modifications must also satisfy the fairness and unconscionability standards applicable to original agreements.

Are online prenup templates enforceable in New York?

Online templates may provide a starting point, but New York's specific requirements—notarization in deed-recording format, maintenance calculations with concrete figures, proper financial disclosure schedules—make professional drafting advisable. Template deficiencies may render agreements unenforceable when challenged, potentially costing far more than attorney fees for proper drafting.

What is a sunset clause in a prenup?

A sunset clause terminates all or part of a prenuptial agreement after a specified period (commonly 5-20 years) or triggering event (birth of a child, home purchase). When the clause activates, expired provisions no longer apply, and New York's default equitable distribution rules govern instead. Not all prenups include sunset clauses—they must be specifically negotiated.

Can a prenup address social media and privacy?

Yes, New York prenuptial agreements may include lifestyle provisions addressing social media conduct, privacy expectations, and confidentiality requirements. Provisions restricting disparaging posts or requiring consent before sharing personal information are generally enforceable if reasonable. Penalty provisions for violations should be proportional to avoid unconscionability challenges.
