In case of foreclosure of any deed of trust, or mortgage, the trustee, mortgagee, or the trustee's or mortgagee's attorney shall record a notice of foreclosure that includes the date when, and the person to whom, a conveyance was made by reason of the foreclosure.

A notice of foreclosure shall consist of a separate instrument, or that part of the original deed of trust or mortgage rerecorded, reciting the information required hereinabove, the names of the original parties to the original instrument foreclosed, and the recording data for the instrument foreclosed. A notice of foreclosure shall be indexed by the register of deeds in accordance with G.S. 161-14.1.
