The mother, alleged father, and guardian or legal custodian of a child may object to an administrative order determining the existence or nonexistence of a parent and child relationship by bringing, within fourteen days after the date the administrative officer issues the order, an action under sections 3111.01 to 3111.18 of the Revised Code in the juvenile court or other court with jurisdiction under section 2101.022 or 2301.03 of the Revised Code in the county in which the child support enforcement agency that employs the administrative officer who issued the order is located. If the action is not brought within the fourteen-day period, the administrative order is final and enforceable by a court and may not be challenged in an action or proceeding under Chapter 3111. of the Revised Code.
