(a) Except as provided in subsection (b) of this section, a person who, at the time of a child's birth, is the spouse of the person who gave birth to the child by assisted reproduction may not challenge the person's parentage of the child unless: (1) Not later than two years after the date of birth of the child, the person commences a proceeding to adjudicate the person's parentage of the child; and (2) the court finds the person did not consent to the assisted reproduction, before, on or after the date of birth of the child, or withdrew consent under section 46b-515 .
(b) A proceeding to adjudicate a spouse's parentage of a child born by assisted reproduction may be commenced at any time if the court determines:
(1) The spouse neither provided a gamete for, nor consented to, the assisted reproduction;
(2) The spouse and the person who gave birth to the child have not cohabited since the probable time of assisted reproduction; and
(3) The spouse never openly held out the child as the spouse's child.
(c) This section shall apply to a spouse's dispute of parentage even if the spouse's marriage is declared invalid after assisted reproduction occurs.
