Ohio Rev. Code § 3123.54: Notice to obligor and registrar.

If a child support enforcement agency, pursuant to section 3123.53 of the Revised Code, determines that an individual holds a license, endorsement, or permit or has applied for, or is likely to apply for, a license, endorsement, or permit, it shall send the notice described in section 3123.55 of the Revised Code to the individual. Not earlier than thirty days after the agency sends the notice to the individual, the agency also may send a notice to the registrar of motor vehicles that gives the name and social security number or other identifying number of the individual and states that a court or agency has determined that the individual is in default under a child support order or has failed to comply with a warrant or subpoena issued by a court or agency with respect to a proceeding to enforce a child support order.

An individual who receives a notice under this section may cooperate with the agency to satisfy one or more of the conditions described in divisions (A) to (E) of section 3123.56 of the Revised Code to prevent notice being sent to the registrar and the resulting driver's license suspension.
