131.222 Acknowledgment of Paternity

The paternity of a child must be determined if the mother is unmarried at the time the child is born.

The paternity of a child does not need to be determined if:

The mother is not married when the child is born because the marriage ended by death or divorce between conception and birth or a court declared the marriage legally void.

The mother of the child or children states that her husband is not the biological father. The woman’s husband is the legal father and has responsibility to support the child or children financially and medically. The husband may challenge responsibility only in court.

For children born on or after Jan. 1, 1998, the Acknowledgment of Paternity (AOP) f orm PA/CS 611 is used by birthing hospitals and the CAO to allow an unmarried birth mother and birth father to acknowledge the paternity of a child born outside marriage.

23 Pa. C.S. § 5103

For voluntary acknowledgment of paternity:

CAO staff must sign the PA/CS 611 as the required witness when the form is completed in their presence.

CCCAO C CAO CAO staff must give written and oral notice to the birth mother and putative father about the legal consequences of and the rights and responsibilities that they are taking on by signing the PA/CS 611 , as well as about the other choices that the parents have such as requesting genetic testing. The PA/CS 611 is the written notification. The CAO staff must explain the form orally to the birth mother and the putative father before they fill out and sign the form.

A completed PA/CS 611 with parents and witness signatures is a conclusive legal finding of paternity, but either the birth mother or the birth father who signed the form may rescind acknowledgment of paternity.

55 Pa. Code § 153.44(e)

23 Pa. C.S. § 5103

Either the birth mother or father signing the PA/CS 611 may send a signed statement asking that acknowledgment be rescinded. The signed statement must be sent to BCSE AOP Program at the address below . The BCSE address is also on the form. The request to rescind the PA/CS 611 must be sent to BCSE no later than 60 days after the form is signed or on the date of a court proceeding about the child, whichever date is sooner.

After the 60-day period or after a court proceeding about the child, whichever date is earlier, a PA/CS 611 may only be challenged in court based on fraud, duress, or material mistake of fact established with clear and convincing proof.

The CAO must mail the completed PA/CS 611 to:

COMMONWEALTH OF PENNSYLVANIA DEPARTMENT OF HUMAN SERVICES BUREAU OF CHILD SUPPORT ENFORCEMENT AOP PROGRAM PO BOX 8018 HARRISBURG, PA 17105-8018

Hospitals and birthing centers are required by law to give unmarried parents of newborns the chance to acknowledge paternity at the time of birth. Hospitals and birthing centers use the PA/CS 611 and send the completed form to BCSE.

23 Pa. C.S. § 5103(c)

NOTE: The father’s name may be included on the record of birth (birth certificate) of the child of unmarried parents only if:

The father and mother have signed a PA/CS 611 or

A court or administrative agency of competent jurisdiction has issued an adjudication of paternity.

TTThe T The BCSE reviews each submitted PA/CS 611 to ensure it is fully and accurately completed before recording the information into the Paternity Tracking System (PTS). It takes three to five weeks from the day the form is submitted to BCSE to certify it in the PTS. The CAO can call, write or fax a request to BCSE for a certified copy of the AOP. See Appendix C, Acknowledgement of Paternity for procedures to access the PTS.

W When a person presents a completed and signed copy of an AOP, the CAO must access the PTS to determine if the AOP is certified. If the PA/CS 611 is not on the PTS and the signature date is less than five weeks, the CAO may assume that paternity is established for determining benefits. Assume paternity was not established if the PA/CS 611 was signed more than five weeks ago and is not in the PTS or if the form does not have:

The first and last names of the mother, the father and the child

Dated signatures of the mother, father and witness

Date of birth of the mother, father and child

Social Security Number for the mother and father

Address of the mother and father

Birthplace of the child.

TT The CAO should always check the PTS to be sure there is no duplicate PA/CS 611 .

TTThe The CAO must follow Section 131.3, Cooperation with Support Requirements support procedures when:

A putative father is not willing to acknowledge paternity voluntarily

The mother denies the putative father’s paternity claim and refuses to sign the PA/CS 611 .

NOTE: The putative father may establish a claim of paternity by signing and having his signature witnessed on an AOP form. An action to establish paternity must be started before the child’s 18th birthday. By signing the form without the mother’s consent, the putative father has the right to receive notice of any proceedings to terminate his parental rights involving the child .
