Ohio Code § 3111.381

§ 3111.381.

(A) Except as provided in divisions (B), (C), (D), (E), and (F) of this section, no person

may bring an action under sections 3111.01 to 3111.18 of the Revised Code unless the person has requested an administrative determination under section 3111.38 of the Revised Code of the existence or nonexistence of a parent and child relationship. (B) An action to determine the existence or nonexistence of a parent and child relationship

may be brought by the child's mother in the appropriate division of the court of common

pleas in the county in which the child resides, without requesting an administrative

determination, if the child's mother brings the action in order to request an order

to determine the allocation of parental rights and responsibilities, the payment of

all or any part of the reasonable expenses of the mother's pregnancy and confinement,

or support of the child.  The clerk of the court shall forward a copy of the complaint to the child support

enforcement agency of the county in which the complaint is filed. (C) An action to determine the existence or nonexistence of a parent and child relationship

may be brought by the putative father of the child in the appropriate division of

the court of common pleas in the county in which the child resides, without requesting

an administrative determination, if the putative father brings the action in order

to request an order to determine the allocation of parental rights and responsibilities.  The clerk of the court shall forward a copy of the complaint to the child support

enforcement agency of the county in which the complaint is filed. (D) An action to determine the existence or nonexistence of a parent and child relationship

may be brought by the caretaker of the child in the appropriate division of the court

of common pleas in the county in which the child resides, without requesting an administrative

determination, if the caretaker brings the action in order to request support of the

child.  The clerk of the court shall forward a copy of the complaint to the child support

enforcement agency of the county in which the complaint is filed. (E) If services are requested by the court, under divisions (B), (C), and (D) of this

section, of the child support enforcement agency to determine the existence or nonexistence

of a parent and child relationship, a Title IV-D application must be completed and

delivered to the child support enforcement agency. (F) If the alleged father of a child is deceased and proceedings for the probate of the

estate of the alleged father have been or can be commenced, the court with jurisdiction

over the probate proceedings shall retain jurisdiction to determine the existence

or nonexistence of a parent and child relationship between the alleged father and

any child without an administrative determination being requested from a child support

enforcement agency. If an action for divorce, dissolution of marriage, or legal separation, or an action

under section 2151.231 or 2151.232 of the Revised Code requesting an order requiring the payment of child support and provision for the

health care of a child, has been filed in a court of common pleas and a question as

to the existence or nonexistence of a parent and child relationship arises, the court

in which the original action was filed shall retain jurisdiction to determine the

existence or nonexistence of the parent and child relationship without an administrative

determination being requested from a child support enforcement agency. If a juvenile court or other court with jurisdiction under section 2101.022 or 2301.03 of the Revised Code issues a support order under section 2151.231 or 2151.232 of the Revised Code relying on a presumption under section 3111.03 of the Revised Code , the juvenile court or other court with jurisdiction that issued the support order

shall retain jurisdiction if a question as to the existence of a parent and child

relationship arises.
