Whenever the Probate Court, in a guardianship matter under chapter 802h, or the Superior Court, in a family relations matter, as defined in section 46b-1, orders a change or transfer of the guardianship or custody of a child who is the subject of a preexisting support order, and the court makes no finding with respect to such support order, such guardianship or custody order shall operate to:

Section applies to all support orders notwithstanding express language in the order barring future modification; to the extent that the application of the specific language of this section to suspend or modify a support order that purports to preclude modification appears to conflict with the general language of Sec. 46b-86(a), this section must prevail. 305 Conn. 539. Section only speaks to child support and does not give a party the right to suspend his alimony obligation. 159 CA 805. To the extent that section conflicts with general provisions of Sec. 46b-86(a) precluding retroactive modification of child support unless service of process requirement in Sec. 52-50 is satisfied, this section must prevail; no practical distinction between a suspension and a modification for purposes of applying section; child support portion of unallocated support award was subject to retroactive modification; section has no bearing on alimony. 161 Conn.App. 271.
