Ohio Rev. Code § 317.14
When a deed, mortgage, power of attorney, or other instrument of writing, for the sale, conveyance, or encumbrance of lands, tenements, or hereditaments, situated in two or more counties in this state, has been recorded in one of such counties, or when a new county is organized and such lands, tenements, or hereditaments are situated within the new county, and the instrument has been recorded in the county from which the new county was taken, or when, by change of county lines, lands are transferred from one county to another and such instrument has been recorded in the county from which the lands were transferred, any person interested in such lands may procure from the county recorder a certified copy of the record and cause it to be recorded in any other county containing such lands, tenements, or hereditaments, in the same manner as the original instrument is required to be recorded. In making the record, such certificate shall be recorded with the copy, and the record of the copy and certificate shall have the same validity and legal effect as the record of the original instrument.
