Ohio Rev. Code § 2107.28: Will lost, spoliated, or destroyed after admission to probate.

If a will is lost, spoliated, destroyed, mislaid, or stolen, after it has been admitted to probate but before it has been recorded, upon notice being given to the persons as provided by section 2107.27 of the Revised Code, the probate court may hear testimony. If the court is satisfied that the contents of the will have been substantially proved, the court may record the will as thus proven. The record shall have all the effects of a record of the original will.
