Any mortgagor who has paid off his mortgage may present the paid mortgage to the clerk of the superior court of the county or counties in which the mortgage instrument is recorded, together with the order of the mortgagee or transferee directing that the mortgage be canceled. After payment of the fee authorized by law, the clerk shall index and record, in the same manner as the original mortgage instrument is recorded, the canceled and satisfied mortgage instrument or such portion thereof as bears the order of the mortgagee or transferee directing that the mortgage be canceled, together with any order of the mortgagee or transferee directing that the mortgage be canceled. The clerk shall show on the index of the cancellation and on the cancellation document the deed book and page number where the original mortgage instrument is recorded. The clerk shall record across the face of the mortgage instrument the words "satisfied" and "canceled" and the date of the entry and shall sign his name thereto officially. The clerk shall also make a notation on the record of the mortgage to indicate where the order of the cancellation is recorded.
