The courts of common pleas are the trial courts of general jurisdiction in the state. They are the only trial courts created by the Ohio Constitution (in Article IV, Section 1). The duties of the courts are outlined in Article IV, Section 4. Each of Ohio's 88 counties has a court of common pleas. The Ohio General Assembly (the state legislature) has the power to divide courts of common pleas into divisions, and has done so, establishing general, domestic relations, juvenile, and probate divisions.
