In each case where the department is appointed to serve as a personal representative or conservator of the estate of a beneficiary of the United States veterans’ administration, the court in which the estate is filed shall authorize a charge for each estate’s share of the bond premium to be paid from the assets of the estate. The department shall determine the charge to be made against each estate, and the aggregate amount of all charges shall not exceed the bond premium. It is the intent of the legislature that this charge shall be the share of each estate in the cost of the bond that the department posts as provided in Section 18 [9-22-18 N.M. Stat. Ann.] of the Veterans’ Services Department Act.
