Legal Question in Family Law in California

I believe that you are asking what you will need to do in order to terminate the father's rights. You will need to do a diligent search for him and prove to the court what you have done to find the father. You may also try to do a "skip trace" (look this up online) to find him. You may also have to ask the court's permission to publish the adoption and termination paperwork. You really do need to speak with an attorney that specializes in family law adoptions to help you with this. Good luck!
