Oregon Revised Statutes Public Health and Safety § 432.098

(1) The Director of the Oregon Health Authority shall adopt by rule a form of a voluntary acknowledgment of paternity that includes the minimum requirements specified by the United States Secretary of Health and Human Services. When the form is signed by both biological parents and witnessed by a third party, the form establishes paternity for all purposes when filed with the State Registrar of the Center for Health Statistics, provided there is no male parent already named in the report of live birth. Establishment of paternity under this section is subject to the provisions and the requirements in ORS 109.070. When there is no other male named as father on the child's record of live birth, the filing of such voluntary acknowledgment of paternity form shall cause the state registrar to place the name of the male parent who has signed the voluntary acknowledgment of paternity form on the record of live birth of the child or, if appropriate, establish a replacement for the record containing the name of the child's male parent, as that parent is named in the voluntary acknowledgment of paternity form. When signed by both parents in the health care facility of the child's birth within five days after the birth, the voluntary acknowledgment of paternity form is not a sworn document. When thus signed, a staff member of the health care facility shall witness the signatures of the parents. In all other circumstances, the form is a sworn document. The filing of the voluntary acknowledgment of paternity form created by this section is subject to the payment of any fees that may apply.

(2) The voluntary acknowledgment of paternity form must contain:

(3) Upon request, the state registrar shall provide a copy of any voluntary acknowledgment of paternity form to the state agency responsible for administration of the child support enforcement program created under Title IV-D of the Social Security Act.  1  The duty imposed upon the state registrar by this section is limited to records of live birth executed and filed with the state registrar after October 1, 1995.
