The Arizona putative father registry is for fathers who may have conceived a child so they can file a claim of paternity. By filing with the registry, the father is entitled to notice of a mother’s adoption plan. A father can register at any time during the pregnancy and up to 30 days after the birth of the child. A father who fails to register within 30 days after the child’s birth waives his right to notification of any adoption proceeding involving the child, and his consent to the adoption is not required. Lack of knowledge of the pregnancy is no excuse for failing to register. The fact that the father had sexual intercourse with the mother is deemed to be notice to him of the pregnancy.
