Ohio Rev. Code § 709.42
If, upon the hearing of a cause of action as provided by section 709.41 of the Revised Code, the court of common pleas finds that the lands are farm lands, and are not within the original limits of the municipal corporation, that by reason of the same being or remaining within the municipal corporation the owner thereof is taxed and will continue to be taxed thereon for municipal purposes in substantial excess of the benefits conferred by reason of such lands being within the municipal corporation, and that said lands may be detached without materially affecting the best interests or good government of such municipal corporation or of the territory therein adjacent to that sought to be detached; then an order and decree may be made by the court, and entered on the record, that the lands be detached from the municipal corporation and be attached to the most convenient adjacent township in the same county. Thereafter the lands shall not be a part of the municipal corporation but shall be a part of the township to which they have been so attached. The costs shall be taxed as may seem right to the court.
