I have a five and a half old daughter. The father has never been in her life ( she has no clue who he is) he went to prison when I was five months pregnant and did sign a paternity paper but never payed child support, we also were never married. My husband and I have now been married for almost a year and a half. He has been in her life for three quarters of it and is the only one she calls dad. She knows she doesn't have our last name and understands she needs to be adopted for him to be her real dad. She wants to be adopted, wants his last name so she can be like us and her three month old sister that is my husband's biological daughter. What do we have to do and how will the courts look at this?
