Ohio Loc. App. R. 2
A party filing a notice of appeal or an original action shall deposit with the Clerk of the Trial Court the sum of $100.00, plus such other fees as the Clerk is authorized by law to collect, except where the party who proffers the filing establishes by affidavit his inability to advance security, or produces evidence that the Trial Court determined that appellant was indigent for purposes of appeal. Of that sum, $75.00 will be security for the payment of costs, and $25.00 is a court of appeals fee, authorized under R. C. 2501.16(B), for the operation of the court. Failure to make the required deposit shall be grounds for dismissal of the appeal.
If an inmate of a state institution files an affidavit of his inability to advance security, the affidavit shall be accompanied by a certificate of the superintendent or other appropriate officer of the institution setting forth the amount of funds, if any, which the inmate may have on deposit with the institution available to the inmate to secure costs. If the certificate demonstrates that the inmate has sufficient funds available to him to secure costs, the Clerk shall not file the notice of appeal or original action until the costs are thus secured.
