There is No father on birth certificate can stepfather adopt?

If the birth father has paid no support and has had no contact with the child for one year, the stepfather may adopt in most states without permission of the birth father. However, this is still a legal process that requires a lawyer and court documents. The price can still range from $500 to $2000. In PA you can't put a father on the birth certificate at birth unless he signs for it and fills out a admission of paternity (if mother is unwed). If he is not listed on the birth certificate he has no legal rights and you don't have to ask him for anything. Especially if he cannot prove he was there or active. And if you went to domestic relations for paternity/support and he didn't show or pay it's an admission and most likely be seen as "turning over" his rights.
