A prenuptial agreement in New York typically costs $1,000 to $5,000 per person, and the spread has less to do with the document than with how it is billed and how much negotiation it takes. Our own flat fee for this work runs $1,500 to $5,000 depending on the complexity of the finances and how much negotiation the agreement needs, quoted in writing after a free consultation and covering drafting, financial disclosure, negotiation and execution. Because each party should have their own lawyer, a couple should budget roughly twice one attorney’s fee for the agreement as a whole.
Prices above that range are common in Manhattan matrimonial practices, particularly where hourly billing meets a long negotiation. Prices far below it usually mean a template, which is a different product with different risks.
What prenups cost in New York
Published market data lines up reasonably well across sources. Marketplace averages for New York run near $960 for drafting and about $630 to $650 for reviewing an agreement someone else drafted. Full-service New York firms are commonly described in the $2,500 to $3,500 range per attorney for drafting, negotiating and finalizing. Complex agreements involving business interests, trusts or cross-border assets reach $5,000 to $10,000 or more per side, and contested negotiations at large matrimonial firms go higher still.
Two structural facts explain most of the spread. The first is billing model: an hourly engagement has no ceiling, and a prenup with several rounds of negotiation can run well past its estimate. The second is that a prenup is really two engagements, because each party needs independent representation.
What drives the price
- Complexity of what you own. A couple with salaries and a savings account is a different document from one with a business, vesting equity, real property or an interest in a family trust.
- Spousal maintenance terms. Waiving or limiting maintenance is the most heavily scrutinized part of a New York prenup, and drafting it properly takes more work than the rest of the agreement combined.
- How much negotiation it takes. If the two sides broadly agree, the document moves quickly. If they don’t, each round of revisions adds cost under hourly billing.
- Timing. Agreements rushed through in the final weeks before a wedding cost more and invite an argument later that one party signed under pressure.
- Where your lawyer practices. Manhattan and Westchester rates run meaningfully above upstate rates for the same document.
What New York requires
New York has not adopted the Uniform Premarital Agreement Act. Prenups here are governed by Domestic Relations Law § 236(B)(3) and a substantial body of case law. Under the statute, the agreement must be:
- In writing. Oral agreements are unenforceable, without exception.
- Signed by both parties, before the marriage.
- Acknowledged or proven in the manner required to entitle a deed to be recorded.
Beyond the statute, courts look at how the agreement came about. Fraud, duress and overreaching are grounds to set one aside, which is why full financial disclosure and independent counsel on both sides matter: they are the evidence that both people understood what they were signing.
Does each person need their own lawyer?
New York does not require it by statute. In practice it is close to essential. One attorney cannot represent both parties in negotiating an agreement about how their assets would be divided, and an agreement where one side had counsel and the other did not is materially easier to attack later.
This is why the cost of a prenup is best understood per person. If your fiancé’s attorney drafted the agreement and you need it reviewed and negotiated, that review is its own engagement, and we quote it as a flat fee too.
When to start
Three to six months before the wedding is comfortable. That leaves room for disclosure, a round or two of negotiation, and proper execution without anyone feeling cornered.
The risk of waiting isn’t only stress. An agreement signed days before the ceremony gives a future court a reason to ask whether the signature was truly voluntary. Time is the cheapest protection available for an agreement’s enforceability.
What about after the wedding?
The same agreement signed after the marriage is a postnuptial agreement, governed by the same section of the Domestic Relations Law and the same signing formality. The process and the fee structure are the same. If a prenup didn’t happen before the wedding, the option hasn’t closed.
Frequently asked questions
How much does a prenup cost in New York?
Typically $1,000 to $5,000 per person, depending on how complex the finances are and how much negotiation the agreement takes. Our flat fee runs $1,500 to $5,000, quoted in writing after a free consultation, covering drafting, disclosure, negotiation and execution. Since each party should have their own attorney, a couple should expect to pay roughly double one side’s fee for the agreement overall.
Do both people need their own lawyer for a prenup?
New York does not require it by statute, but it is close to essential in practice. One attorney cannot represent both parties, and an agreement where only one side had counsel is significantly easier to challenge later.
What makes a prenup enforceable in New York?
Under Domestic Relations Law § 236(B)(3), the agreement must be in writing, signed by both parties before the marriage, and acknowledged in the manner required for a deed to be recorded. Courts will also set agreements aside for fraud, duress or overreaching, which is why full financial disclosure matters.
Is a prenup just notarized, or is there more to it?
There is more to it. The acknowledgment must meet the formal requirements for recording a real estate deed, which is stricter than a standard notarization. A defective acknowledgment can invalidate an otherwise well-drafted agreement years later.
Can we use an online prenup template instead?
Templates exist and cost less, but they carry the risks you are paying a lawyer to remove: terms that don’t fit New York law, maintenance provisions drafted without the statutory framework in mind, and execution that misses the deed-style acknowledgment. For couples with a business, real property or equity compensation, the gap between a template and a drafted agreement is where later disputes tend to live.
How far before the wedding should we start?
Three to six months is comfortable. That allows time for financial disclosure, negotiation and proper execution. Agreements signed in the final days before a wedding invite a later argument that one party signed under pressure.
