Legal Question in Family Law in Georgia

Yes, but please focus on the question you didn't ask. Your boyfriend is in a huge legal mess and he needs a lawyer (and a divorce). His wife's child belongs to him even though he is not the father as Georgia law presumes he is the father and must support that child. This can be settled in a divorce, but the longer this goes on the harder it gets to fix.

You can give your child the last name of his/her father. Even though your boyfriend and his wife are separated, he is still considered the legal father of the child born to his wife and her boyfriend. He is in a tangled mess and he needs to get out of it. You may wish to speak to an attorney on child support and other issues which could arise with your child.
