(a) Duty to pay.--Parties liable for apportionment of the Federal estate tax, whether residents or nonresidents of this Commonwealth, shall pay the amounts apportioned against them at the time the Federal estate tax is due, without regard to any extension of time for paying such tax.

(b) Power of fiduciary.--The fiduciary charged with the duty to pay the Federal estate tax may recover from parties liable to apportionment the amounts of Federal estate tax apportioned to them. If the fiduciary pays the tax apportioned against another party, the fiduciary may recover from the other party the tax payment so advanced, together with interest of 5% per annum from the date of payment.

(c) Suspending distribution.--Distribution or delivery of property to any party, other than a fiduciary charged with a duty to pay the Federal estate tax, shall not be required of any fiduciary until that party pays the Federal estate tax apportioned to that party.

(d) Court decrees.--Notwithstanding subsections (a) and (b), the court, upon petition or at an accounting or in any appropriate action or proceeding, shall make such decrees or orders as it shall deem advisable apportioning the Federal estate tax. The court may direct a fiduciary to collect the apportioned amounts from the property or interests in his possession of any parties against whom apportionment has been made and may direct all other parties against whom the Federal estate tax has been or may be apportioned or from whom any part of the Federal estate tax may be recovered to make payment of the apportioned amounts to the fiduciary. When a fiduciary holds property of a party liable to apportionment insufficient to satisfy the apportioned Federal estate tax, the court may direct that the balance of the apportioned amount of Federal estate tax shall be paid to the fiduciary by the party liable. Should an overpayment of the Federal estate tax be made by any party or on his behalf, the court may direct an appropriate reimbursement for the overpayment. If the court apportions any part of the Federal estate tax against any party interested in nontestamentary property or among the respective interests created by any nontestamentary instrument, the court, in its discretion, may assess against those properties or interests an equitable share of the expenses incurred in connection with the determination and apportionment of the Federal estate tax. If the fiduciary cannot recover the Federal estate tax apportioned against a party benefited, the unrecovered amount shall be charged in such manner as the court may determine.
