When an estate is committed by order of the appropriate circuit court, or clerk thereof, to any person on the motion of a creditor or other person pursuant to § 64.2-610, the tax due under this article for such administration shall be paid by the party upon whose motion the estate was committed. The amount of tax paid by such creditor or other person shall be repaid to him by the administrator so appointed out of the first funds received by him from the sale of such estate. If an estate is committed to a person without motion the person shall be required to pay such tax as soon as assets of the estate, sufficient to cover the tax due, have come into his hands.
