CGS § 46b-503. Adjudicating parentage of child with alleged genetic parent.

(a) If in a proceeding to determine whether an alleged genetic parent who is not a presumed parent is a parent of a child and the person who gave birth to the child is the only other person with a claim to parentage of the child, the court shall adjudicate an alleged genetic parent to be a parent of the child if the alleged genetic parent:

(1) Is identified under section 46b-500 as a genetic parent of the child and the identification is not successfully challenged under said section;

(2) Admits parentage in a pleading, when making an appearance, or during a hearing, the court accepts the admission, and the court determines the alleged genetic parent to be a parent of the child;

(3) Declines to submit to genetic testing ordered by the court or a child support agency, in which case the court may adjudicate the alleged genetic parent to be a parent of the child even if the alleged genetic parent denies a genetic relationship with the child;

(4) Is in default after service of process and the court determines the alleged genetic parent to be a parent of the child; or

(5) Is neither identified nor excluded as a genetic parent by genetic testing and, based on other evidence, the court determines the alleged genetic parent to be a parent of the child.

(b) Subject to the limitations set forth in sections 46b-495 to 46b-505, inclusive, if, in a proceeding involving an alleged genetic parent, at least one other person in addition to the person who gave birth to the child has a claim to parentage of the child, the court shall adjudicate parentage under section 46b-475.

(c) If in a proceeding involving an alleged genetic parent, another person other than the person who gave birth is a parent of the child, the alleged genetic parent can seek a determination that such person is the child's parent under section 46b-475, in addition to the existing parents. An adjudication of parentage under this subsection that the alleged genetic parent is a parent shall not disestablish the parentage of any other parent.
