Can a pre-nuptial agreement stand even if it is not notarized?

A pre nup is a valid enforceable contract if its terms are agreed to by both parties and signed. It is not mandatory that a Prenuptial Agreement be notarized, although acknowledgments before a notary public are the norm on Prenuptial Agreements. The purpose of the acknowledgment is 1) to ensure that there is proof that the person who signed the Prenuptial Agreement is the person who signed the Prenuptial Agreement; and 2) to enable the Prenuptial Agreement to be recorded by the County Recorder (which is rarely done, because people typically want to keep their Prenuptial Agreements and their Disclosure Attachments private). Only were your spouse to claim that the signature purporting to be his/hers on the Prenuptial Agreement isn't hers/his, would there be a problem, which could nevertheless be resolved by a handwriting expert and/or by deposing the attorney who signed the certification by attorney on his/her behalf.

Maybe yes, maybe no. There's no requirement that a pre-marital agreement be notarized. BUT if a premarital agreement isn't properly prepared, then even notarizing it won't make it more enforceable. Someone needs to review the actual agreement with an experienced family law attorney.

How many times do you need to ask the same question? The answer is "until I get the answer I want!"
