Sec. 305.         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 circuit 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 person seeking registration the order has not been modified; and(3) except as otherwise provided in Section 209, the     name and address of the person seeking registration and any parent or person acting as a 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), the registering  court shall:(1) cause the determination to be filed as a foreign     judgment, together with one copy of any accompanying documents and information, regardless of their form; and(2) serve notice upon the persons named pursuant to     subsection (a)(3) and provide them with an opportunity to contest the registration in accordance with this Section.(c) The notice required by subsection (b)(2) must 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 20 days after service of notice; and(3) failure to contest the registration will 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 person seeking to contest the validity of a registered order must  request a hearing within 20 days after service of the notice.  At that hearing,  the  court shall confirm the registered order unless the person contesting  registration  establishes that:(1) the issuing court did not have jurisdiction under     Article 2;(2) the child-custody determination sought to be     registered has been vacated, stayed, or modified by a court having jurisdiction to do so under Article 2; or(3) the person contesting registration was entitled     to notice, but notice was not given in accordance with the standards of Section 108, in the proceedings before the court that issued the order for which registration is sought.(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 and the person  requesting registration and all persons served must be notified of the  confirmation.(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.
