Section 750 ILCS 46/617 - Rules for adjudication of parentage The court shall apply the following rules to adjudicate the parentage of a child:
(a) The parentage of a child having an adjudicated parent may be disproved only by admissible results of genetic testing, or other means, excluding that person as the parent of the child or identifying another person as the parent of the child.(b) Unless the results of the genetic testing or other evidence are admitted to rebut other results of genetic testing, a person identified as the parent of a child under Section 404 of this Act may be adjudicated the parent of the child.(c) If the court finds that genetic testing under Section 404 neither identifies nor excludes a person as the parent of a child, the court may not dismiss the proceeding. In that event, the results of genetic testing and other evidence are admissible to adjudicate the issue of parentage.(d) Unless the results of genetic testing are admitted to rebut other results of genetic testing, a person excluded as the parent of a child by genetic testing may be adjudicated not to be the parent of the child.Added by P.A. 099-0085,§ 617, eff. 1/1/2016.
