Each county (and the City of St. Louis) has its own circuit court, and small claims are filed with its circuit clerk in the associate circuit division; Jackson County has two courthouses (Kansas City and Independence). File in the county where the defendant lives, where the deal or problem happened, where you live if the defendant can be found there, or where a business defendant has an office or registered agent.
