Any city office, in which deeds, mortgages, or other instruments were required or authorized to be recorded by the city’s special charter in lieu of recording the instruments in the office of the recorder in the county where the city, or a major portion thereof, is situated, shall be discontinued whenever the city is incorporated under this Code. The city officer, who holds this office and has custody of the records, books, and papers of the office, shall deliver them to the recorder of the county specified in this section, and shall take the receipt of the recorder therefor. Thereafter, these records, books, and papers shall be a part of the records of the recorder’s office and shall have the same legal effect as if they had been originally a part of the records of the recorder’s office. They, or certified transcripts made therefrom, shall have the same force and effect as evidence as other records in the recorder’s office.
