To add a father/second parent to a birth certificate where a father/second parent is not currently listed, complete and submit the Voluntary Acknowledgement of Parentage form | In Spanish.

Remove a father/second parent from a birth certificate

To remove a father's/second parent's name from a birth certificate, you must submit a copy of certified court documents showing paternity/parentage determination with a completed data worksheet for the new birth certificate.

Court-determined paternity/parentage documents are required to add, remove or change a father's/second parent's name on a birth certificate when another individual is shown as the parent of the child on the original certificate.

A new certificate may be prepared only when a determination of paternity/parentage is made by a court of competent jurisdiction or following adoption. A divorce decree is not acceptable evidence regarding paternity/parentage.

Certified copies of acknowledgement of parentage
