My son has my ex-husband last name, but he is not the father of my son. I got pregnant when my ex-husband and I were split, after I got pregnant, we were trying to get back, so when I had my son, I gave my ex-husband last name because his biological father was never around. But things didn't work out, so we finally got divorced. His name was never on birthcertificat or his biological father's name either. I just want to give my son my maiden name because all my son got is me. How can I do this?

Your going to have to seek the fathers permission. Have you been to court for custody and support?
