Establishing Paternity in New Mexico

The mother and a man claiming to be the genetic father may sign an acknowledgment of paternity on the state vital records bureau's form, under penalty of perjury, before or after the birth; it takes effect at birth or on filing with the bureau, whichever is later, and is the equivalent of a court adjudication of paternity. A signer may rescind only through a court proceeding brought by the earlier of 60 days after the acknowledgment takes effect or the first court hearing about the child in which the signer is a party (with a later deadline for signers who were minors). After that, it can be challenged only for fraud, duress or material mistake of fact, within two years after filing (or after a minor signer turns 18).
