(1) If the court in this Commonwealth has jurisdiction under section 5913 (relating to jurisdiction), it may proceed with the case unless a court in another state acquires jurisdiction under provisions similar to section 5913 before the appointment or issuance of the order.

(2) If the court in this Commonwealth does not have jurisdiction under section 5913, whether at the time the petition is filed or at any time before the appointment or issuance of the order, the court shall stay the proceeding and communicate with the court in the other state. If the court in the other state has jurisdiction, the court in this Commonwealth shall dismiss the petition unless the court in the other state determines that the court in this Commonwealth is a more appropriate forum.
