(a) General rule.--A court of this Commonwealth has temporary emergency jurisdiction if the child is present in this Commonwealth and the child has been abandoned or it is necessary in an emergency to protect the child because the child or a sibling or parent of the child is subjected to or threatened with mistreatment or abuse.

(b) No previous custody determination or proceeding.--If there is no previous child custody determination that is entitled to be enforced under this chapter and a child custody proceeding has not been commenced in a court of a state having jurisdiction under sections 5421 (relating to initial child custody jurisdiction) through 5423 (relating to jurisdiction to modify determination), a child custody determination made under this section remains in effect until an order is obtained from a court of a state having jurisdiction under sections 5421 through 5423. If a child custody proceeding has not been or is not commenced in a court of a state having jurisdiction under sections 5421 through 5423, a child custody determination made under this section becomes a final determination if it so provides and this Commonwealth becomes the home state of the child.

(c) Previous custody determination or 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 5421 through 5423, any order issued by a court of this Commonwealth under this section must specify in the order a period that the court considers adequate to allow the person seeking an order to obtain an order from the state having jurisdiction under sections 5421 through 5423. The order issued in this Commonwealth remains in effect until an order is obtained from the other state within the period specified or the period expires.

(d) Mandatory communication between courts.--A court of this Commonwealth which has been asked to make a child custody determination under this section, upon being informed that a child custody proceeding has been commenced in or a child custody determination has been made by a court of a state having jurisdiction under sections 5421 through 5423, shall immediately communicate with the other court. A court of this Commonwealth which is exercising jurisdiction pursuant to sections 5421 through 5423, upon being informed that a child custody proceeding has been commenced in or a child custody determination has been made by a court of another state under a statute similar to this section, shall immediately communicate with the court of that state to resolve the emergency, protect the safety of the parties and the child and determine a period for the duration of the temporary order.
