It may not be enough to only register with the putative father registry. Several states require that the biological father support the mother and the child before and after the birth. In a few published cases, fathers have lost their children to adoption or are fighting to overturn adoptions because the courts said they didn't adequately support the child and mother. In one case, the father said the mother was told by the adoption agency not to accept gifts or money for the child while she was pregnant, but he gave her things for her other child and helped her with expenses not directly related to the pregnancy. The court ruled that he hadn't met the legal requirements and allowed the adoption.
