Ohio Rev. Code § 2111.31
If the report of the appraisers under section 2111.30 of the Revised Code is favorable to the lease and on the final hearing the court is of the opinion that it will be to the advantage of the ward, those whom the ward is required by law to support, or the estate to lease the real property, the probate court shall make an order authorizing the lease to be made by public or private letting, as it considers best, on the terms, covenants, conditions, and stipulations, either in accordance with those set forth in the petition or otherwise, that it directs, provided the terms, covenants, conditions, and stipulations are not less favorable to the ward than those reported by the appraisers. The lease shall not take effect until the lease and the security, if any, prescribed in the lease are approved and confirmed.
The lease made pursuant to the court order may provide that the improvements shall be made by the tenant as part of the rent, or by the guardian, either out of the rent or other means of the ward as the court directs.
If the lease is for the mining or removal of mineral or other substances and the guardian is unable to lease the lands upon the terms ordered, the guardian may report the fact to the court and the court may change the terms of leasing, but not below the customary royalty in the vicinity of the lands.
