Ohio Rev. Code § 5723.15: Purchasers may have partition.

Any person claiming any land, inlot, outlot, or part of lot, by virtue of a sale made under sections 5723.01 to 5723.19 of the Revised Code, as tenant in common with any other person, may apply for a partition in the manner provided by law for the partition of real estate. On presenting the county auditor's deed, the court, before which application for such partition is made, shall set off to such person the land claimed in the deed as his share in the manner prescribed by law for the partition of estates in lands, tenements, or hereditaments of joint tenants pursuant to a joint tenancy created prior to the effective date of this amendment, or of tenants with a right of survivorship, tenants in common, and coparceners.
