Can you adopt your girlfriends child?

I believe that you would have to go to your town or state house and get the paper work. I think it would be the same as adopting a child who isn't your girlfriends. It may also depend on the state the child resides in and if the father still has child rights to the kid. You may then have to custody battle the father (these is a rare case and the father, whom of which does not want anything to do with the child, should easyly give up his rights)
