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:

  1. Unmarried Birth parent and Alleged parent
  2. Married or unmarried Birth parent and Intended parent (for couples who use assisted reproduction) eligible to sign LDSS-5157

One of the parents MUST be the birth parent.
Otherwise, parentage must be established in court.

Complete or verify the AOP form

   

The Acknowledgment of Parentage form (LDSS-5171) consists of six (6) required sections. Brief instructions and illustrations for each section are listed below. Use the buttons on the right to display or hide all the illustrations. Links in the text open individual images in a separate window.

Whether you assist the parents in completing each section or simply collect and submit a form they have completed, you should carefully review each section of the form. Forms should be legibly written in black ink, typed, or filled electronically. All required information should be entered.

  1. Top of the form. Providers should enter their Hospital Code and check that the correct box for "where signed" is marked.
    Note: Only the Birth Registrar can enter the district and register numbers.

  2. Child's section of the form. The child's full name, the name and address of the hospital, the child's date of birth, and the child's gender should be entered. If the child's name has been crossed out or written over, a new form must be completed.

  3. Birth parent's section of the form. The birth parent must provide full name, address, place of birth, date of birth, Social Security number, and marital status. The birth parent must sign the form in front of two witnesses. Witnesses cannot be related to either parent.

  4. Other parent's section of the form. The other parent must provide full name, address, place of birth, date of birth, and Social Security number. The other parent must sign the form in front of two witnesses. Witnesses cannot be related to either parent.

    2. Where the child was conceived using assisted reproduction and the assistance of a gamete donor, enter the gamete donor's address—if known.

  6. Registrar's sections of the form:
    1. Recorded District and Register numbers at the top of the form.
      Note: Only the Birth Registrar can enter the district and register numbers.

Parents may complete the AOP form at another place

If parents are unable to complete an AOP form in the hospital or birthing center, parents may complete the Child, Birth Parent, Other parent and Mailing address sections and file the form themselves with the registrar of the district where the birth certificate is filed.

Parents should be sure to check "Other" for "where signed," but they must not complete the Registrar's sections at the top or bottom of the form.

Other marked at top of LDSS-5171

Parents must sign the form in front of two witnesses who are not related to either parent. The parents can then send or deliver the signed and witnessed form to the appropriate registrar.
