My husband's son's mother moved out of state and in with her parents when she was 3 months pregnant with their son and then never put him on the birth certificate and ended up giving their son her maiden name. She is now married and took her husband's last name and so now all three of the have different last names. My husband has been asking her to agree to change their son's last name to his since generally, that's one of the normal things to go, kids have their father's last names, especially because he (well, we) are and have been a major part of his son's life since she decided to move back to the state. She has refused from the beginning, first stating that even if she got married, she would keep her maiden name (which she didnt), and then because her father does not and supposedly cannot have any sons and so there is no one to carry on the "family name", but we don't feel this is fair as her father is NOT my stepson's father and has only seen him once in the last 2 years. I understand he would have to take it to court, but is there a high possibility that my husband would be allowed to get his son's name changed through the courts even if the mother continues to object?
