My ex and I had a baby, we lived 6 months together when we found out I was pregnant. At first he had a job but after I got a job of my own he got fired and never bothered to work again, I was the one supporting us, he would get jobs but very short lived (a week at most), he hit me on a regular basis, he has a drug problem and an anger management problem. I moved out of our apartment one night after a very severe beating, I moved with a friend of mine. The baby was born in MArch and he gave him his last name. We never got anything from him after the baby was born, just a box of diapers and $ 20. We were reconciling when we had a violent encounter again, this time he assaulted his mother and sister for defending me and left the house with a knife after I had left. I filed a restraining order and haven't seen him or heard from him. He tried to break into my friend's house (I'd just moved out) and a police report was filed. He hasn't seen the baby or tried to have any kind of contact. I want to take his hast name off the birth certificate, what do I need to do and, could I win a case in court??
The baby is 8 months old and we live in Tennessee.
