Ohio Rev. Code § 323.29
The partial payment of delinquent taxes charged on the tax duplicate against any entry of real property, as authorized by section 323.133 or 323.31 of the Revised Code, shall not prevent such real property from being certified as delinquent; however, partial payment of such taxes under section 323.133 of the Revised Code shall preclude the commencement of foreclosure proceedings unless the tax commissioner subsequently certifies to the county auditor that partial payment under such section is no longer authorized. Partial payment of delinquent taxes in accordance with the terms of a delinquent tax contract under section 323.31 of the Revised Code shall preclude the commencement of foreclosure proceedings unless the county treasurer subsequently certifies to the county auditor that the delinquent tax contract has become void.
