Ohio Rev. Code § 5307.04
If the court of common pleas finds that the plaintiff in an action for partition has a legal right to any part of the estate, it shall order partition of the estate in favor of the plaintiff or all interested parties, appoint one suitable disinterested person to be the commissioner to make the partition, and issue a writ of partition. The court on its own motion may, and upon motion of a party or any other interested person shall, appoint one or two additional suitable persons to be commissioners. If the estate to be partitioned extends beyond the county in which the action is commenced, the court may appoint a separate commissioner or commissioners, not to exceed three, to make the partition of that portion of the estate located in the other county.
