§ 46b-115w. Registration of child custody determination
(a) A child custody determination issued by a court of another state may be registered in this state, with or without a simultaneous request for enforcement, by sending to the Superior Court in this state: (1) A letter or other document requesting registration; (2) two copies, including one certified copy, of the determination sought to be registered, and a statement under penalty of perjury that to the best of the knowledge and belief of the petitioner the order has not been modified; and (3) except as otherwise provided in section 46b-115s, the name and address of the petitioner and any parent or person acting as parent who has been awarded custody or visitation in the child custody determination sought to be registered.
(b) On receipt of the documents required by subsection (a) of this section, the registering court shall cause the determination to be filed as a foreign judgment, together with one copy of any accompanying documents and information, regardless of their form.
(c) Within five days after the registering court's receipt of the documents required by subsection (a) of this section, the petitioner shall notify the persons named pursuant to subdivision (3) of subsection (a) of this section of the registration of the documents by certified mail, return receipt requested at their respective last-known addresses or by personal service, and provide them with an opportunity to contest the registration in accordance with this section. The notice required in this subsection shall state that: (1) A registered determination is enforceable as of the date of the registration in the same manner as a determination issued by a court of this state; (2) a hearing to contest the validity of the registered determination must be requested within twenty days after service of notice; and (3) failure to contest the registration will, upon proof of notice, result in confirmation of the child custody determination and preclude further contest of that determination with respect to any matter that could have been asserted.
(d) A hearing to contest the validity of the registered determination shall be requested within twenty days after service of the notice. Such hearing shall be held within twenty days of the receipt of such request. At that hearing, the court shall confirm the registered order unless the respondent establishes that: (1) The issuing court did not have jurisdiction under a provision substantially similar to section 46b-115k, 46b-115l or 46b-115m; (2) the child custody determination sought to be registered has been vacated, stayed or modified by a court having jurisdiction to do so pursuant to a statute substantially similar to sections 46b-115k to 46b-115m, inclusive; or (3) the respondent was entitled to notice of the proceedings before the court that issued the order for which registration is sought, but such notice was not given in a manner reasonably calculated to give actual notice.
(e) If a timely request for a hearing to contest the validity of the registration is not made, the registration is confirmed as a matter of law with respect to those who have received proper notice and all persons served must be notified of the confirmation by the petitioner.
(f) Confirmation of a registered order, whether by operation of law or after notice and hearing, precludes further contest of the order with respect to any matter that could have been asserted at the time of registration.
