14-2-823. Binding effect of determination of parentage.

(a) Except as otherwise provided in subsection (b) of this section, a determination of parentage is binding on:

(i) All signatories to an acknowledgement or denial of paternity as provided in article 5 of this act; and

(ii) All parties to an adjudication by a court acting under circumstances that satisfy the jurisdictional requirements of W.S. 20-4-142.

(b) A child is not bound by a determination of parentage under this act unless:

(i) The determination was based on an unrescinded acknowledgment of paternity and the acknowledgement is consistent with the results of genetic testing;

(ii) The adjudication of parentage was based on a finding consistent with the results of genetic testing and the consistency is declared in the determination or is otherwise shown; or

(iii) The child was a party or was represented in the proceeding determining parentage by an attorney representing the child's best interest.

(c) In a proceeding to dissolve a marriage, the court is deemed to have made an adjudication of the parentage of a child if the court acts under circumstances that satisfy the jurisdictional requirements of W.S. 20-4-142, and the final order:

(i) Expressly identifies a child as a "child of the marriage," "issue of the marriage," or similar words indicating that the husband is the father of the child; or

(ii) Provides for support of the child by the husband unless paternity is specifically disclaimed in the order.

(d) Except as otherwise provided in subsection (b) of this section, a determination of parentage may be a defense in a subsequent proceeding seeking to adjudicate parentage by an individual who was not a party to the earlier proceeding.

(e) An adjudication of the paternity of a child issued by a court of this state or by the filing of an acknowledgment of paternity pursuant to W.S. 14-2-605 without the benefit of genetic testing, may be challenged by a party to the adjudication only if post-adjudication genetic testing proves that the adjudicated father is not the biological father of the child pursuant to W.S. 14-2-817. This section does not apply to any of the following:

(i) A paternity determination made in or by a foreign jurisdiction or a paternity determination which has been made in or by a foreign jurisdiction and registered in this state in accordance with the Uniform Interstate Family Support Act;

(ii) A paternity determination based upon a court or administrative order of this state if the order was entered based upon blood or genetic test results which demonstrate that the alleged father was not excluded and that the probability of the alleged father's paternity was ninety-nine percent (99%) or higher.

(f) A petition for disestablishment of paternity shall be filed:

(i) In the district court in which the paternity order is filed;

(ii) In the case of an adjudication as a result of the filing of an acknowledgment of paternity pursuant to W.S. 14-2-605, notwithstanding any other provision of this chapter, the petition shall be filed within the earlier of two (2) years after the petitioner knew or should have known that the paternity of the child was at issue or as provided in W.S. 14-2-809(b);

(iii) In the case of an adjudication issued by a court of this state, the petition shall be filed only by the mother of the child, the adjudicated father of the child, the child, if the child was a party to the adjudication, or the legal representative of any of these parties. A petition filed by an individual who is not a party to the adjudication shall be filed pursuant to W.S. 14-2-809. The petition under this paragraph shall be filed no later than two (2) years after the petitioner knew or should have known that the paternity of the child was at issue.

(g) The court shall appoint an attorney to represent the best interests of a child if the court finds that the best interests of the child is not adequately represented. In cases concerning an adjudication of paternity pursuant to subsection (c) of this section, the court shall appoint an attorney to represent the best interests of the child. In determining the best interests of the child, the court shall consider the following factors:

(i) The length of time between the proceeding to adjudicate parentage and the time that the adjudicated father was placed on notice that he might not be the genetic father;

(ii) The length of time during which the adjudicated father has assumed the role of the father of the child;

(iii) The facts surrounding the adjudicated father's discovery of his possible nonpaternity;

(iv) The nature of the relationship between the child and the adjudicated father;

(v) The age of the child;

(vi) The harm that may result to the child if adjudicated paternity is successfully disproved;

(vii) The nature of the relationship between the child and any alleged father;

(viii) The extent to which the passage of time reduces the chances of establishing the paternity of another man and a child support obligation in favor of the child; and

(ix) Other factors that may affect the equities arising from the disruption of the father-child relationship between the child and the adjudicated father or the chance of other harm to the child.

(h) The court may order genetic testing pursuant to article 7 of this chapter.

(j) The court may grant relief on the petition filed in accordance with this section upon a finding by the court of all of the following:

(i) The relief sought is in the best interests of the child pursuant to the factors in this section;

(ii) The genetic test upon which the relief is granted was properly conducted;

(iii) The adjudicated father has not adopted the child;

(iv) The child is not a child whose paternity is governed by article 9 of this chapter;

(v) The adjudicated father did not act to prevent the biological father of the child from asserting his paternal rights with respect to the child.

(k) If the court determines that test results conducted in accordance with W.S. 14-2-703 and 14-2-704 exclude the adjudicated father as the biological father, the court may nonetheless dismiss the action to overcome paternity and affirm the paternity adjudication if:

(i) The adjudicated father requests that paternity be preserved and that the parent-child relationship be continued; or

(ii) The court finds that it is in the best interests of the child to preserve paternity. In determining the best interests of the child, the court shall consider all of the factors listed in this section.

(m) If the court finds that the adjudication of paternity should be vacated, in accordance with all of the conditions prescribed, the court shall enter an order which provides all of the following:

(i) That the disestablishment of paternity is in the best interests of the child pursuant to the factors in this section;

(ii) That the adjudicated father is not the biological father of the child;

(iii) That the adjudicated father's parental rights and responsibilities are terminated as of the date of the filing of the order;

(iv) That the birth records agency shall amend the child's birth certificate by removing the adjudicated father's name, if it appears thereon, and issue a new birth certificate for the child;

(v) That the adjudicated father is relieved of any and all future support obligations owed on behalf of the child from the date that the order determining that the established father is not the biological father is filed;

(vi) That any unpaid support due prior to the date the order determining that the adjudicated father is not the biological father is filed, is due and owing;

(vii) That the adjudicated father has no right to reimbursement of past child support paid to the mother, the state of Wyoming or any other assignee of child support.

(n) Participation of the Title IV-D agency in an action brought under this section shall be limited as follows:

(i) The Title IV-D agency shall only participate in actions if services are being provided by the Title IV-D agency pursuant to title 20 chapter 6 of the Wyoming Statutes;

(ii) When services are being provided by the Title IV-D agency under title 20 chapter 6 of the Wyoming Statutes, the Title IV-D agency may assist in obtaining genetic tests pursuant to article 7 of this chapter;

(iii) An attorney acting on behalf of the Title IV-D agency represents the state of Wyoming in any action under this section. The Title IV-D agency's attorney is not the legal representative of the mother, the adjudicated father or the child in any action brought under this section.

(o) The costs of genetic testing, the fee of any guardian ad litem and all court costs shall be paid by the person bringing the action to overcome paternity unless otherwise provided by law.

(p) A man presumed to be the father of a child without adjudication of paternity may bring a proceeding to adjudicate paternity pursuant to W.S. 14-2-807.
