750 ILCS 36/304: Temporary Visitation.

(a) A court of this State which does not have jurisdiction to modify a child-custody determination, may issue a temporary order enforcing:

(1) a visitation schedule made by a court of another state; or

(2) the visitation provisions of a child-custody determination of another state that does not provide for a specific visitation schedule.

(b) If a court of this State makes an order under subsection (a)(2), it shall specify in the order a period that it considers adequate to allow the petitioner to obtain an order from a court having jurisdiction under the criteria specified in Article 2. The order remains in effect until an order is obtained from the other court or the period expires.
