This section complements Section 202 [Me. cite section 1746] and is addressed to the court that is confronted with a proceeding to modify a custody determination of another State. It prohibits a court from modifying a custody determination made consistently with this Act by a court in another State unless a court of that State determines that it no longer has exclusive, continuing jurisdiction under Section 202 [Me. cite section 1746] or that this State would be a more convenient forum under Section 207 [Me. cite section 1751]. The modification State is not authorized to determine that the original decree State has lost its jurisdiction. The only exception is when the child, the child's parents, and any person acting as a parent do not presently reside in the other State. In other words, a court of the modification State can determine that all parties have moved away from the original State. The court of the modification State must have jurisdiction under the standards of Section 201 [Me. cite section 1745].

3.__Previous determination or pending proceeding.__If there is a previous child custody determination that is entitled to be enforced under this chapter or a child custody proceeding has been commenced in a court of a State having jurisdiction under sections 1745 to 1747, any order issued by a court of this State under this section must specify in the order a period that the court considers adequate to allow the person seeking an order to
