My step son will be 8 on 7/21. My husband (his father) and i have been married 6 years. His biological mother dropped him off my our door step back in 2008 never to be seen or heard from again. We are wanting to change his name and i want to adopt him. We are not seeking child support or any money from her. We are content with her not being in his life. My son doesnt know that i am not his biological mother. My husband and I live here in SC and she lives in NC. We do not want to allow her any type of visitation. How can we go about doing this???
