Voluntary acknowledgment of paternity for a child born out of wedlock in Arizona, used to add the father to the birth record. It is a Department of Economic Security form; the form says to mail it to the DCSS Hospital Paternity Program in Phoenix.
Who can use this form
- Both parents sign. The health department's web page says the child must be under 18.
- It does not apply if the mother was married at the time of birth or in the ten months before it, unless a Waiver of Paternity Affidavit or a court order or decree rebutting paternity is attached.
- Each signature must be witnessed or notarized. A witness must be at least 18 and not related to either parent by blood or marriage.
- After the child is 3 months old, only the child's last name can be changed with this form.
What to send with it
- All pages of the acknowledgment except the completion instructions, filled in with black ink and with no corrections.
- A separate acknowledgment for each child in a multiple birth.
- Do not mail any money to the Hospital Paternity Program.
- For an amended birth certificate, the health department's web page asks for the Request for Copy of Birth Certificate (VS-11), a copy of an ID or a notarized signature, a self-addressed stamped envelope and the fee.
- The health department's web page gives a different route from the form: it says to submit the acknowledgment to a county vital records office or to the Bureau of Vital Records.
