The recorder, when recording at length instruments in writing in the office, may transcribe the instruments in handwriting or typewriting, make photographic or photostatic reproductions of the instruments, or transcribe the instruments partly in handwriting or typewriting and make photographic or photostatic reproductions of the remaining portions of the instruments. Every document, however, shall be filed in a complete and intelligible manner. The recorder may not accept facsimile or other photographic or photostatic copies of the signatures of parties executing documents without labeling those signatures as copies unless they are digital signatures submitted under federal or State law. When photographic or photostatic reproductions are used, the recorder shall first be satisfied that the reproductions are as lasting and durable as handwritten or typewritten copies. The reproductions may be upon sheets bound together in well bound books or placed in books that are permanently locked so that the sheets cannot be tampered with or removed. When instruments are reproduced by microphotography, digital scanning, or reproduced on film as provided in this Section the reproduction thus made shall be deemed the record for all purposes.
