Adding or changing parents on a birth certificate

There are only two ways to add or change who is listed as a parent on a birth certificate: Acknowledgment of Parentage or Court Order.

  1. Acknowledgment of Parentage
    The Acknowledgment of Parentage is an administrative process used to:
  • Establish a parent-child relationship
  • Add a second parent to the birth certificate
  1. Court Order

You need a court order if:

  • There are questions about who is a parent of the child
  • The parties do not agree on who is a parent of the child
  • The parties want to add or remove parent(s) on the child's birth certificate.

To order a Parentage Verification Letter, submit the Parentage Verification Order form (DOH 422-163) (PDF) to the Department of Health.

Note: This information does not apply to adoption or surrogacy situations. Visit the Adoption page or Surrogacy page for information.
