It shall be lawful for a personal representative to provide for perpetual care for the lot upon which is located the grave of the testator or intestate, and the cost thereof shall be paid and credited as such in final accounts: Provided, that the provisions of this section shall be applicable to an interment made in a cemetery authorized by law to operate as a perpetual-care cemetery or association, and the cost thereof shall be in the sound discretion of the personal representative having due regard to the value of the estate and to the interest of the surviving spouse and the heirs and devisees of the estate. Provided, where the personal representative desires to spend more than two hundred fifty dollars ($250.00) for such purpose, and the will does not grant specific authority to the personal representative for such expenditure in excess of two hundred fifty dollars ($250.00), the personal representative shall file the personal representative's petition before the clerk of the superior court and such order as will be made by the court shall specify the amount to be expended for such purpose.
