Ohio Rev. Code § 2151.271
Except in a case in which the child is alleged to be a serious youthful offender under section 2152.13 of the Revised Code, if the child resides in a county of the state and the proceeding is commenced in a juvenile court of another county, that court, on its own motion or a motion of a party, may transfer the proceeding to the county of the child's residence upon the filing of the complaint or after the adjudicatory, or dispositional hearing, for such further proceeding as required. The court of the child's residence shall then proceed as if the original complaint had been filed in that court. Transfer may also be made if the residence of the child changes. The proceeding shall be so transferred if other proceedings involving the child are pending in the juvenile court of the county of the child's residence.
Whenever a case is transferred to the county of the child's residence and it appears to the court of that county that the interests of justice and the convenience of the parties requires that the adjudicatory hearing be had in the county in which the complaint was filed, the court may return the proceeding to the county in which the complaint was filed for the purpose of the adjudicatory hearing. The court may thereafter proceed as to the transfer to the county of the child's legal residence as provided in this section.
Certified copies of all legal and social records pertaining to the case shall accompany the transfer.
