**Tex. Fam. Code § 160.637. BINDING EFFECT OF DETERMINATION OF PARENTAGE.** (a) Except as otherwise provided by Subsection (b) or Section 160.316, a determination of parentage is binding on: (1) all signatories to an acknowledgment or denial of paternity as provided by Subchapter D; and (2) all parties to an adjudication by a court acting under circumstances that satisfy the jurisdictional requirements of Section 159.201. (b) A child is not bound by a determination of parentage under this chapter unless: (1) the determination was based on an unrescinded acknowledgment of paternity and the acknowledgment is consistent with the results of genetic testing; (2) 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 (3) the child was a party or was represented in the proceeding determining parentage by an attorney ad litem. (c) In a proceeding to dissolve a marriage, the court is considered to have made an adjudication of the parentage of a child if the court acts under circumstances that satisfy the jurisdictional requirements of Section 159.201, and the final order: (1) expressly identifies the child as "a child of the marriage" or "issue of the marriage" or uses similar words indicating that the husband is the father of the child; or (2) provides for the payment of child support for the child by the husband unless paternity is specifically disclaimed in the order. (d) Except as otherwise provided by Subsection (b), 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) A party to an adjudication of paternity may challenge the adjudication only under the laws of this state relating to appeal, the vacating of judgments, or other judicial review.
