Ohio Rev. Code Ann. § 2101.20

When the aggregate amount of fees and allowances collected by the probate judge in any calendar year exceeds by more than ten per cent the amount necessary to pay the salaries of the judge and the employees of the probate court, including court constables, for the same calendar year, the judge may, by an order entered on the judge's journal, provide for a discount of all the fees and allowances the judge is required to charge and collect for the use of the county by fixing a per cent of discount that shall be applied to all the earnings of the office for the ensuing year and shall constitute the legal fees of the office for that year.
