I have a 7 month old child who isn't biologically my ex - boyfriend's child. We were together at the time of birth and he signed the birth certificate and the vap form at the hospital. We have since broken up and he doesn't want his name on my child's birth certificate and also wants me to drop his last name from my child's name. My child's name was hyphenated with both of our last names. How do I go about getting this problem fixed. The real birth father and I have no contact with each other. I don't know where he is because he left the state.
