Of course he can legally do this. There should be a form in your local superior court for a voluntary termination of parental rights.
Actually Chattanooga, Tennessee Courts do not want one parent to surrender their rights unless someone else is going to simultaneously adopt the child. If for any reason you were to go on some sort of state welfare, the State would be looking to recover some of that expense from father, even if he never had a part of child's life. If you do have someone that is wiling to adopt the child (one of your parents, a current husband, a boyfriend even) and assume legal and financial responsibility for the child until your child turns 18, the child's father can surrender. Otherwise I think you are going to find that the courts are not going to take father's surrender of his parental rights.
