Ohio Rev. Code § 727.37: Court of common pleas jurisdiction.

The court of common pleas shall have the jurisdiction authorized by sections 727.01 to 727.49, inclusive, of the Revised Code, for the collection of any charge or debt or the enforcement of any lien, notwithstanding the amount involved is less than that to which the jurisdiction is limited in other cases. Such courts may make such special rules concerning the class of cases authorized to be brought under such sections as will tend to expedite the disposition and prevent unnecessary costs.
