Acknowledgment
A notarial formality required for New York prenups: the agreement must be signed in front of a notary public with specific certificate language, same as recording a deed.
New York Domestic Relations Law §236(B)(3) requires prenups to be acknowledged with the same formalities required to record a deed in New York. This means the parties sign in front of a notary, and the notary affixes a specific acknowledgment certificate.
In Matisoff v. Dobi (1997), the New York Court of Appeals struck down a prenup solely because it lacked the proper acknowledgment — even though both parties' signatures were undisputed. The defect cannot be cured retroactively. This is the single most common technical reason New York prenups are voided.
