Amend a Birth Certificate to Acknowledge Paternity

A.R.S. § 36-334 requires that if a mother is not married at the time a child is born and has not been married any time during the preceding 10 months, no father will be named on the birth certificate unless both parents file sworn statements or unless so ordered by a court of competent jurisdiction.

Sworn Statements (Acknowledgment of Paternity)

The Acknowledgment of PaternityPDF form may be used to establish paternity for a child under the age of 18 if both parents are in agreement as to the identity of the biological father. These forms are available at all birthing hospitals, the Office of Vital Records, the Arizona Department of Economic Security's Child Support Enforcement offices and many of the county registrar's offices.

Parents may choose to complete the Acknowledgment of Paternity at the hospital when the child is born or may do it later. In either case, the father's name will not be added to the birth certificate until the form is filed with the County or State Office of Vital Records, or the DES Hospital Paternity Program.

The Acknowledgment of Paternity form is a two-part form that must be completed in BLACK INK and may contain NO ERRORS. If there are any errors, white-outs, changes, strikeouts or other alterations, or it will be rejected.

Both parents must sign the Acknowledgment of Paternity form and both signatures must be notarized or witnessed. Failure to sign the acknowledgment, or lack of a notary or witness on any signature will cause the form to be rejected. DO NOT FORGE THE SIGNATURE OF EITHER PARENT. CLAIMS OF FORGERY WILL BE INVESTIGATED.

Acknowledgment of Paternity can also be used to change the child's last name to the father’s last name. Also note that acknowledgment can be used to change any part of the child’s name from birth to 3 months of age. This process can be done in person or by mail.

Either parent may request to rescind the Acknowledgment of Paternity by completing the Waiver of Paternity Affidavit.PDF This form must be completed and mailed to the Arizona Department of Economic Security's Hospital Paternity Program at 2290 W. Guadalupe Road, Building 3, Gilbert, Arizona 85233 within 60 days after the last signature (mother or father) is affixed on the Acknowledgment of Paternity.

Please include the appropriate fee with your request. Acceptable forms of payment are credit card (write your credit card number on the application if submitting your request by mail). You must include the card type and expiration date. Other acceptable forms of payment are cashier's check or money order made payable to the Office of Vital Records. We do not accept personal checks. See the fee schedule for the State Office of Vital Records.

A copy of your valid government issued identification that contains your photo and signature is required or you must have your signature notarized on the affidavit.

Court Ordered Paternity

A court order of paternity is required under the following circumstances:

  1. to establish paternity for an adult 18 years of age or older
  2. to establish paternity when one parent cannot be located or is deceased
  3. to remove a father from the birth record and add another one

Court orders may be filed with the Office of Vital Records directly by the Court, the agency that petitioned the Court for the order, or one of the parents may deliver it in person. If you decide to bring a court order to the Office of Vital Records in person, you must bring a certified copy of the court order with you, and submit a completed Affidavit to Correct or Amend a Birth CertificatePDF.

The processing fee of a court ordered paternity is NOT paid by the Court. If the order is filed by the Court and an application for certified copies is received later, the applicant must pay the amendment fee before the certified copies can be issued. The fee includes one certified copy of the birth certificate with the father's name on it. Additional certified copies may be purchased; reference the fee schedule for the State Office of Vital Records.
