Ohio Revised Code Title LI. Public Welfare § 5120.133

(A) The department of rehabilitation and correction, upon receipt of a certified copy of the judgment of a court of record in an action in which a prisoner was a party that orders a prisoner to pay a stated obligation, may apply toward payment of the obligation money that belongs to a prisoner and that is in the account kept for the prisoner by the department. The department may transmit the prisoner's funds directly to the court for disbursement or may make payment in another manner as directed by the court. Except as provided in rules adopted under this section, when an amount is received for the prisoner's account, the department shall use it for the payment of the obligation and shall continue using amounts received for the account until the full amount of the obligation has been paid. No proceedings in aid of execution are necessary for the department to take the action required by this section.

(B) The department may adopt rules specifying a portion of an inmate's earnings or other receipts that the inmate is allowed to retain to make purchases from the commissary and that may not be used to satisfy an obligation pursuant to division (A) of this section. The rules shall not permit the application or disbursement of funds belonging to an inmate if those funds are exempt from execution, garnishment, attachment, or sale to satisfy a judgment or order pursuant to section 2329.66 of the Revised Code or to any other provision of law.
