If the biological father's name is not on the legal birth certificate and has had zero contact with me or my son, he does not pay any child support and has never. How will this affect my husband adopting my son and taking his name? He is the only father my son has ever known and will ever know! He has been a part of my son's life since the age of 4 months old and my son is 2 now. We recently got married and we want to have only one last name. My son has my maiden name now! I am a Louisiana resident!

Thanks so much in advance for your responses!
