Ohio Rev. Code Ann. § 3121.04

When a person who fails to comply with a withholding notice described in section 3121.03 of the Revised Code and issued to enforce a court support order derives income from self-employment or commission, is employed by an employer not subject to the jurisdiction of the court, or is in any other employment situation that makes issuance of a withholding notice impracticable, the court may require the person to enter into a cash bond to the court in a sum fixed by the court at not less than five hundred nor more than ten thousand dollars, conditioned that the person will make payment as previously ordered.
