Hello, I have been with this wonderful man for almost seven years now and have to little girls with him. Before we were married I brought to the relatioinship a 2 year old little boy from a previous relatioinship from my teen years. My husband has always wanted to adopt my son. My son knows no other father but my husband due to the fact that his natural father wanted nothing to do with him. I have not heard from him in over 10 years and wanted to know how can my husband legally adopt my son. We have never showed our son his birth certificate due to the fact that the father space is blank. please advise...
