in order to remove natural father's name, your friend will need to hire a lawyer to do this. It will need the natural's father to consent of stripping him of all his natural father's rights and also please take note, mcys will be notified and your friend and the father will have to agree mutually. It will not be a very simple legal case as it concern a minor. if your friend's looking to divorce him legally (since they are ROMed), it will be good for her to remove his rights at the same time in order to retain her sole custody's rights over the child.
