Ohio Revised Code Title XXI. Courts Probate Juvenile § 2111.26

A guardian may lease the possession and use of the real property of the guardian's ward or any part of it for a term of years, renewable or otherwise, by perpetual lease, with or without the privilege of purchase, or may lease upon the terms and for the time that the probate court approves any lands belonging to the ward containing coal, gypsum, petroleum oil, natural gas, gravel, stone, or any other mineral substance for the purpose of drilling, mining, or excavating for and removing any of those substances, or the guardian may modify or change in any respect any lease previously made.

The lease, or modification or change in a lease previously made, may be made when the guardian of the person and estate or of the estate only applies to the court by which the guardian was appointed and the court finds that the lease or modification or change is necessary for the support of the ward or of the ward's family, for the payment of the just debts of the ward, for the ward's education, if a minor, to secure the improvement of the real property of the ward and increase the rent, to pay any liens or claims against the real property, if the court finds that the real property is suffering unavoidable waste, or that in any other respect it will be for the best interests of the ward or those persons for whom the ward is required by law to provide.
