Ohio Rev. Code § 2729.06: County auditor's deed.

The deeds made by the county auditor of lands sold at delinquent or forfeited tax sales are not prima-facie evidence of title in the purchaser of such lands, nor is there any presumption in favor of such tax deeds or sales when the records of the sale and the proceedings upon which it was based have been lost or destroyed by fire, riot, or civil commotion.
