Ohio Rev. Code § 5307.03
A person entitled to partition of an estate may file his petition therefor in the court of common pleas, setting forth the nature of his title, a pertinent description of the lands, tenements, or hereditaments of which partition is demanded, and naming each tenant in common, coparcener, or other person interested therein, as defendant. When the title to such estate came to such person by descent or devise upon the death of an inhabitant of this state, a partition thereof shall not be ordered by the court within one year from the date of the death of such decedent, unless the petition sets forth and it is proved that all claims against the estate of such decedent have been paid, or secured to be paid, or that the personal property of the deceased is sufficient to pay them.
