Legal Question in Family Law in New Mexico

See an attorney who specializes in adoption. Some but not all family law attorneys do adoptions. There's a heading in the yellowbook for attorneys - adoption. You will have to terminate the parental rights of both parents - abandonment is one ground for that, so if the mother has not seen the child for that long it should be easy. You will have to do the same for the father, if he is still living.

Good luck. The child is lucky to have a grandparent willing to step in like this.
