My daughters biological father has not been in contact since she was 2 weeks old. My daughter is now 4. I have since gotten married and my husband would like to adopt her. Her biological father never signed the acknowledgement of paternity and his name is not on the birth certificate. I have been unable to contact him to see if he will voluntarily terminate his parental rights. What steps should I take next? Do I still need to file a petition for involuntary termination of parental rights?
