Instructions for Voluntary Acknowledgment of Parentage
What is voluntary Acknowledgment of Parentage (AOP)?
Voluntary Acknowledgment of Parentage (AOP) is a simple administrative process through which unmarried couples and married couples who use assisted reproduction can establish legal parentage. Offering parents the opportunity to complete an Acknowledgment of Parentage form in a hospital or birthing center means parents can begin to establish legal parentage even as soon as the day the child is born.
Be sure the parents are eligible for AOP
Before discussing Acknowledgment of Parentage with new parents, make sure they are eligible to sign the AOP form. Only two people can sign the form to establish parentage. The two people may fit one of two scenarios:
- Unmarried Birth parent and Alleged parent
- Married or unmarried Birth parent and
(for couples who use assisted reproduction)
One of the parents MUST be the birth parent.
Otherwise, parentage must be established in court.
