Legal Question in Family Law in New Mexico

File a petition to determine paternity and establish custody of the child with you. That will give you the judicial proceeding to stop any adoption and if girlfriend only does what her parents want at least you can have a judge hear you out and make decision about who gets custody of a child the mother does not want. As between mother and father - if mother does not want the child and father does . . . . . I'd suspect father gets the child. Good Luck.
