In cases where a person has been given a durable power of attorney by a lessee of a safe deposit box who has become mentally incompetent, and the original copy of the power is put in the box, the lessor may permit the person given the power to open the box to obtain the original copy of the power. The lessor may request the person purporting to have been given the durable power of attorney to produce a certified copy of the power or an affidavit declaring that he has been given the power before opening the box. No other contents may be removed from the box pursuant to this section.

The durable power of attorney provided for in this section means a power made durable under the provisions of Section 62-5-501.
