(a) Except as provided in sections 46b-495 to 46b-505, inclusive, in any proceeding under sections 46b-450 to 46b-553, inclusive, to adjudicate parentage, the court or a family support magistrate shall order the child and any other person to submit to genetic testing if a request for testing is supported by the sworn statement of a party:

(1) Alleging a reasonable possibility that the person is the child’s genetic parent; or

(2) Denying genetic parentage of the child.

(b) A child support agency shall require genetic testing only if there is no presumed, acknowledged or adjudicated parent of a child other than the person who gave birth to the child.

(c) The court, a family support magistrate or child support agency may not order in utero genetic testing.

(d) If two or more persons are subject to court-ordered genetic testing, the court may order that testing be completed concurrently or sequentially.

(e) Genetic testing of a person who gave birth to a child is not a condition precedent to testing of the child and a person whose genetic parentage of the child is being determined. If the person is unavailable or declines to submit to genetic testing, the court may order genetic testing of the child and each person whose genetic parentage of the child is being adjudicated.

(f) In a proceeding to adjudicate the parentage of a child having a presumed parent or a person who claims to be a parent under § 46b-490, the court may deny a motion for genetic testing of the child and any other person after considering the factors set forth in subsections (a) and (b) of § 46b-475.

(g) If a person requesting genetic testing is barred under § 46b-469, 46b-483, 46b-489, 46b-503 or 46b-510 from establishing the person’s parentage, the court shall deny the request for genetic testing.

(h) A default judgment may be ordered against a person who refuses to submit to court-mandated genetic testing under this section and in accordance with subsection (g) of § 46b-560.
