(2) A child is bound by a determination of parentage only if: (a) The determination was based on an unrescinded acknowledgment of parentage and the acknowledgment is consistent with the results of genetic testing; (b) The determination was based on a finding consistent with the results of genetic testing and the consistency is declared in the determination or otherwise shown; (c) The child was conceived by assisted reproduction, including under a gestational surrogacy agreement, and the determination of parentage was made under ORS 109.206 to 109.218 or 109.222 to 109.244; or (d) The child was a party or was represented by an attorney in the proceeding.
