Ohio Rev. Code § 2329.46: Remedy of purchaser if sale invalid.

Upon the sale of property on execution, if the title of the purchaser is invalid by reason of a defect in the proceedings, he may be subrogated to the right of the creditor against the debtor to the extent of the money paid and applied to the debtor's benefit, and, to the same extent, may have a lien on the property sold, as against all persons, except bona fide purchasers without notice. This section does not require the creditor to refund the purchase money by reason of the invalidity of such sales.

This section applies to sales by order of court, sales by executors, administrators, guardians, and assignees, and to sales for taxes.
