Ohio Rev. Code Ann. § 733.61

If the court hearing a case under section 733.59 of the Revised Code is satisfied that the taxpayer had good cause to believe that his allegations were well founded, or if they are sufficient in law, it shall make such order as the equity of the case demands. In such case the taxpayer shall be allowed his costs, and, if judgment is finally ordered in his favor, he may be allowed, as part of the costs, a reasonable compensation for his attorney.
