The surety on the warehouseman’s bond must be joined as a party to the insolvency proceeding upon a motion by the commissioner if the commissioner believes proceeds from the warehouseman’s bond may be needed to redeem outstanding receipts issued by the warehouseman. If it appears in the best interests of the receiptholders, the commissioner may order the surety to deposit the penal sum of the bond, or so much of the sum as may be deemed necessary, into the trustee‘s trust account pending a final determination of the surety’s liability under the bond.
