To change the child's last name all you need is for the father to receive notice of the proceedings through the probate court, where you would file the request to amend the birth certificate. If you wanted the father's parental rights terminated, you would need to seek a stepparent adoption. Lack of contact for a year is a means to establish abandonment that will allow the court to grant the stepparent adoption.
