I am hoping to adopt my ex-husband's great nephew who is now nineteen years old. His biological mother is my, now, ex-husband's niece. When he was five months old both of his biological parents "gave" him to my, now ex-husband and me. When he was nine months we were granted legal guardianship. When he was fifteen years old I divorced and was granted sole physical and legal custody and now I want to adopt him. He is nineteen and 110% in agreement of the adoption. Will I have to serve either his biological parents or my ex-husband? Will this be an Independent or Relative adoption?
