Proceedings Where Instrument Creating Charge on

Land in Duplicate, Triplicate, or More Parts. When any mortgage, lease or other instrument creating or dealing with a charge upon registered land, or any estate or interest therein, is in duplicate, triplicate, or more parts, only one of the parts need be filed and kept in the registrar's office; but the registrar shall note upon the register whether the same is in duplicate, triplicate, or as the case may be, and shall also mark upon the others mortgagee's duplicate, lessor's duplicate, lessee's duplicate, or as the case may be, and note upon the same the date of filing and the volume and folio of the register where the memorial is entered, and deliver them to the parties entitled thereto.
