I'm in this serious relationship with this Brazilian girl right now, and we have been together for a year almost. She has a son who is already two years old, and from what she told me, the father of the son abandoned them a long time ago and is not helping them financially or anything. My question is can I adopt her son to be mines? She told me that the father will probably not sign the papers which makes no sense but there has to be law permitting that he has too.
