(a) At any time after the first anniversary of the date letters testamentary are granted for an estate, a creditor of the estate whose claim or part of a claim has been approved by the court or established by suit may obtain an order directing that payment of the claim or part of the claim be made on written application and proof, except as provided by Subsection (b), showing that the estate has sufficient available funds.
(b) If the estate does not have available funds to pay a claim or part of a claim described by Subsection (a) and waiting for the estate to receive funds from other sources would unreasonably delay the payment, the court shall order the sale of estate property sufficient to make the payment.
(c) The personal representative of the estate must first be cited on a written application under Subsection (a) to appear and show cause why the order should not be made.
