20 Pa.C.S. § 4112

When a share of an estate administered in the Commonwealth is distributable to a nonresident minor, a trustee subject to the jurisdiction of a foreign court, or a nonresident incapacitated person, the court may award it to the guardian or committee of the nonresident appointed in the foreign jurisdiction, or to such trustee: Provided, That the court shall be satisfied, in all cases where an applicable will or trust instrument does not direct distribution to the foreign guardian, committee or trustee, that adequate security or other protection has been provided in the domiciliary jurisdiction by the domiciliary law for the protection of the persons beneficially interested in the share so awarded.
