Prison father wanting rights
I live in Texas and I have a 6 year old daughter that I had out of wedlock. The man who I thought was the father signed the birth certificate and the affidavit of paternity. When my daughter started to age I noticed that she looked like another guy I was fooling around with. Well the other guy saw her and also believed her to be his, however he stated he wanted nothing to do with her. Now he's in jail and is calling me after 6 years claiming he has rights to see the child and wants her name changed to his. My daughter doesn't know this guy, and to make matters worse she is living with the dad whose name is on her birth certificate. I need to know if there is anything I can do to prevent this matter from going to court and what rights does he have after all this time?
