Ohio Revised Code Title XXI. Courts Probate Juvenile § 2151.232

If an acknowledgment has been filed and entered into the birth registry pursuant to section 3111.24 of the Revised Code but has not yet become final, either parent who signed the acknowledgment may bring an action in the juvenile court or other court with jurisdiction under section 2101.022 or 2301.03 of the Revised Code under this section requesting that the court issue an order requiring a parent of the child to pay an amount for the support of the child in accordance with Chapters 3119., 3121., 3123., and 3125. of the Revised Code.

The parties to an action under this section may raise the issue of the existence or nonexistence of a parent-child relationship. If an action is commenced pursuant to this section and the issue of the existence or nonexistence of a parent-child relationship is raised, the court shall treat the action as an action commenced pursuant to sections 3111.01 to 3111.18 of the Revised Code. If the issue is raised, the court shall promptly notify the office of child support in the department of job and family services that it is conducting proceedings in compliance with sections 3111.01 to 3111.18 of the Revised Code. On receipt of the notice by the office, the acknowledgment of paternity signed by the parties and filed pursuant to section 3111.23 of the Revised Code shall be considered rescinded.

If the parties do not raise the issue of the existence or nonexistence of a parent-child relationship in the action and an order is issued pursuant to this section prior to the date the acknowledgment filed and entered on the birth registry becomes final, the acknowledgment shall be considered final as of the date of the issuance of the order. An order issued pursuant to this section shall not affect an acknowledgment that becomes final pursuant to section 3111.25 of the Revised Code prior to the issuance of the order.
