Ohio Rev. Code § 2111.28
In an application for authority to lease real property of a ward under sections 2111.26 and 2111.27 of the Revised Code, the guardian may act for two or more wards and two or more guardians of different wards may unite if all the wards are jointly or in common interested in the real property. If the same person is guardian of two or more wards owning lands in common, the wards may be joined as defendants in the same petition under section 2111.27 of the Revised Code.
The ward's spouse shall be made a defendant to the petition, and if the proposed lease is for the purpose of mining or removing mineral or other substances and the spouse files an answer consenting to the lease, free and discharged of all right and expectancy of dower, the answer shall be a full release of the spouse's expectancy of dower when the lease is confirmed. Unless in the answer an allowance in lieu of dower is waived, the court shall allow, out of the proceeds of the lease, a sum in money that is the just and reasonable value of the expectancy of dower.
