Sec. 204. Presumption of parentage.
(a) A person is presumed to be the parent of a child if:
(1) the person and the mother of the child have     entered into a marriage, civil union, or substantially similar legal relationship, and the child is born to the mother during the marriage, civil union, or substantially similar legal relationship, except as provided in the Gestational Surrogacy Act or other law;
(2) the person and the mother of the child were in a     marriage, civil union, or substantially similar legal relationship and the child is born to the mother within 300 days after the marriage, civil union, or substantially similar legal relationship is terminated by death, declaration of invalidity of marriage, judgment for dissolution of marriage, civil union, or substantially similar legal relationship, or after a judgment for legal separation, except as provided in the Gestational Surrogacy Act or other law;
(3) before the birth of the child, the person and the     mother of the child entered into a marriage, civil union, or substantially similar legal relationship in apparent compliance with law, even if the attempted marriage, civil union, or substantially similar legal relationship is or could be declared invalid, and the child is born during the invalid marriage, civil union, or substantially similar legal relationship or within 300 days after its termination by death,  declaration of invalidity of marriage, judgment for dissolution of marriage, civil union, or substantially similar legal relationship, or after a judgment for legal separation, except as provided in the Gestational Surrogacy Act or other law; or
(4) after the child's birth, the person and the     child's mother have entered into a marriage, civil union, or substantially similar legal relationship, even if the marriage, civil union, or substantially similar legal relationship is or could be declared invalid, and the person is named, with the person's written consent, as the child's parent on the child's birth certificate.
(b) If 2 or more conflicting presumptions arise under this Section, the presumption which on the facts is founded on the weightier considerations of policy and logic, especially the policy of promoting the child's best interests, controls.

Sec. 205. Proceedings to declare the non-existence of the parent-child relationship.
(a) An action to declare the non-existence of the parent-child relationship may be brought by the child, the birth mother, or a person presumed to be a parent under Section 204 of this Act.  Actions brought by the child, the birth mother, or a presumed parent shall be brought by verified complaint, which shall be designated a petition.

 After a presumption under Section 204 of this Act has been rebutted, parentage of the child by another man or woman may be established in the same action, if he or she has been made a party.
(b) An action to declare the non-existence of the parent-child relationship brought under subsection (a) of this Section shall be barred if brought later than 2 years after the petitioner knew or should have known of the relevant facts.  The 2-year period for bringing an action to declare the non-existence of the parent-child relationship shall not extend beyond the date on which the child reaches the age of 18 years.  Failure to bring an action within 2 years shall not bar any party from asserting a defense in any action to declare the existence of the parent-child relationship.
(c)  An action to declare the non-existence of the parent-child relationship may be brought subsequent to an adjudication of parentage in any judgment by the man adjudicated to be the parent pursuant to a presumption in paragraphs (a)(1) through (a)(4) of Section 204 if, as a result of deoxyribonucleic acid (DNA) testing, it is discovered that the man adjudicated to be the parent is not the father of the child.  Actions brought by the adjudicated father shall be brought by
verified petition.  If, as a result of the deoxyribonucleic acid (DNA) testing that is admissible under Section 614 of this Act, the petitioner is determined not to be the father of the child, the adjudication of paternity and any orders regarding the allocation of parental responsibilities, parenting time, and future payments of support may be vacated.
(d) An action to declare the non-existence of the parent-child relationship brought under subsection (c) of this Section shall be barred if brought more than 2 years after the petitioner obtains actual knowledge of relevant facts.  The 2-year period shall not apply to periods of time where the birth mother or the child refuses to submit to deoxyribonucleic acid (DNA) testing.  The 2-year period for bringing an action to declare the non-existence of the parent-child relationship shall not extend beyond the date on which the child reaches the age of 18 years.
