Ohio Rev. Code § 3119.41
If either a court, under section 3119.40 of the Revised Code, or child support enforcement agency, under section 3119.38 or 3119.39 of the Revised Code, makes a final determination that no mistake of fact exists in a national medical support notice referred to in a notice of medical support enforcement activity sent to a person, the national medical support notice shall remain in effect. If a court or agency determines that a mistake of fact does exist under the national medical support notice, the court or agency, as appropriate, shall take whatever action is necessary regarding the notice, which may include correction or termination of the notice.
If a mistake of fact proceeding is instituted under section 3119.38 or 3119.40 of the Revised Code, withholding of amounts pursuant to a national medical support notice shall continue in accordance with the notice until the court or agency, as appropriate, terminates or corrects the notice. If the notice is corrected, withholding shall occur in accordance with the corrected notice.
