Prenups in NYC: A 2026 Refresh
For New York couples planning a wedding in 2026, a prenup is the document that decides what happens to your assets, vesting equity, and income if the marriage ends. New York is an equitable distribution state, which means courts divide marital property based on fairness rather than a strict 50/50 split. Prenups in NYC override those default rules with the couple's chosen terms.
Key takeaways
- Prenups in NYC are enforceable under NY DRL 236 Section 236(B)(3) if the agreement is in writing, signed by both partners, and acknowledged in the manner required for a deed to be recorded.
- New York is an equitable distribution state. Without a prenup, the court divides marital property based on a broader fairness standard. With a prenup, the couple sets the rules.
- The 2026 cost of a NYC prenup is $5,000 flat with a concierge service like Neptune, $1,997 with HelloPrenup's full attorney tier, or $5,000 to $25,000+ at a traditional NYC matrimonial firm.
- Independent counsel for each partner is the practical floor. Both partners need their own state-licensed family law attorney, either bundled in a flat-fee concierge model or retained separately.
- Full financial disclosure is required. Each partner must disclose assets, debts, income, and equity grants. A prenup signed without disclosure can be invalidated later.
What makes a NYC prenup enforceable
NY DRL Section 236(B)(3) sets the enforceability requirements:
1. In writing: the prenup must be a written document.
2. Signed by both partners: both must sign before the wedding.
3. Acknowledged with the formality required to record a deed: notarized acknowledgment by both partners.
Beyond the statutory requirements, courts review prenups in NYC for full financial disclosure, independent counsel for each partner, substantive fairness at execution and enforcement, and voluntary execution without coercion or duress. Per the NYC Bar guidance on marital agreements, the substantive fairness review can look at whether the agreement remains fair at the time of enforcement, not just at signing. A NYC prenup that meets all these requirements is enforceable. One that misses any is challengeable.
What a NYC prenup typically covers
For a NYC couple with standard assets, the prenup covers:
- Separate property: each partner's premarital assets (the apartment, the brokerage account, the retirement plan, any business interests).
- Marital property: how income and assets acquired during the marriage are characterized.
- Vesting equity: RSUs, options, or other equity grants vesting during the marriage. Important for NYC tech and finance couples.
- Real estate: the family apartment or brownstone, including how appreciation during the marriage is treated.
- Spousal support: whether spousal support is waived, capped, or determined by formula.
- Death provisions: how the prenup interacts with each partner's estate plan and what each is entitled to if the other dies.
For couples whose wedding date has already passed, a postnuptial agreement is the during-marriage equivalent that Neptune drafts on the same couple-first, flat-fee model.
How Neptune fits
Neptune's $5,000 flat-fee prenup is built for the standard NYC couple shape: dual-career, some vesting equity at a top company, planning to marry in the next 6 to 12 months. Each partner gets a state-licensed NY family law attorney from the vetted network. AI-led intake plus synchronous attorney drafting and negotiation. Two to four weeks from intake to signed document.
For NYC couples with multi-entity business structures, contested negotiation, or active litigation posture, Neptune refers to a traditional NYC matrimonial firm.

Frequently asked questions
Is a NYC prenup enforceable in court?
Yes, if drafted to meet NY DRL Section 236(B)(3) requirements: in writing, signed by both partners, properly acknowledged, with full financial disclosure and independent counsel. The substantive fairness review at enforcement is the other piece.
How long does a NYC prenup take?
At Neptune, two to four weeks from intake to signed document. At a traditional NYC matrimonial firm, typically two to four months across both partners' attorneys.
Do we both need a lawyer?
Practically yes. Independent counsel for each partner is the floor for enforceability and the standard practice in NYC. Neptune includes both attorneys in the flat fee; traditional firms charge each partner separately.
What if the prenup is challenged later?
The court reviews the four enforceability factors: written form, full disclosure, independent counsel, substantive fairness. A properly drafted prenup that meets all four is difficult to challenge successfully.
Do we need a notary?
Yes. NY DRL Section 236(B)(3) requires the prenup to be acknowledged in the manner required to record a deed, which means notarization.
Does the prenup need to be filed with a court?
No. The prenup is a private contract between the two partners. It does not get filed with a court at signing. It only comes into play if the marriage ends and one partner needs to invoke it.
Can prenups in NYC cover future business ventures?
Yes. The prenup can characterize a business acquired or grown during the marriage as separate property (with the appropriate documentation) or as marital property. NYC prenups often address planned business ventures explicitly.
