A prenup amendment changes specific clauses in an agreement you already signed, while a postnuptial agreement is a fresh contract for spouses who never signed a prenup or who want to fully replace the old one. Couples on the Upper East Side and in Tribeca most often ask for an amendment after a real change: one spouse launches a business near Wall Street, an inheritance arrives, a child is born, or a co-op purchase in Battery Park City reshapes the balance sheet. When the original terms still mostly work, a targeted amendment is faster and lower-cost. When the terms no longer reflect the marriage at all, a full postnuptial agreement is the cleaner path.

New York courts apply the same fairness tests to postnuptial agreements that they apply to prenups, and both spouses must give full and honest financial disclosure. That matters because a postnup signed after the wedding gets closer scrutiny than a prenup, the couple is already married, so the contract must be voluntary, understood, and free of pressure. We draft both spouses' terms so the agreement reads as balanced, which is what holds up if it is ever tested. Signing at 60 Centre Street is never required; a postnuptial or amendment is a private contract, notarized and kept between the two of you, not filed with the New York County Supreme Court.

The relationship framing is the whole point. Reopening a prenup, or adding a postnup years into a marriage in Murray Hill or Greenwich Village, is not a sign of trouble, it is two people updating the plan to match the life they actually built. A calm, both-sides-fair document lowers future conflict instead of creating it. Because the service is 100% online, spouses in Harlem, Chelsea, SoHo, the Financial District, or the Upper West Side review drafts on their own schedule between work and wedding-season commitments, with no in-person office appearance.

The attorney handling your amendment or postnuptial agreement has 34 years of experience, admitted to practice since 1991, and every engagement is a flat fee, no hourly meter running while you decide what to change. You know the price before drafting starts.

Common questions

Can I amend my prenup after marriage in New York?
Yes. In New York you can amend a prenup after marriage by signing a written amendment that both spouses acknowledge before a notary, the same formality required for the original agreement under Domestic Relations Law §236(B)(3).
What is the difference between a postnuptial agreement and a prenup in New York?
In New York a prenup is signed before the wedding and a postnuptial agreement is signed after; both are legally recognized, but a postnup often faces closer fairness review because the couple is already married and disclosure and voluntariness must be clear.
Do I need to go to court to sign a postnuptial agreement in New York?
No. A New York postnuptial agreement is a private contract between spouses, notarized rather than filed, so no appearance at the New York County Supreme Court or any courthouse is required.
How much does a postnuptial agreement cost in New York?
New York postnuptial agreements are commonly handled on a flat fee in the $3,500, $5,500 range, with short prenup amendments starting lower; the exact flat fee is confirmed before drafting begins.
