Every Wisconsin county has its own circuit court, and small claims cases are filed with that county's Clerk of Circuit Court (a few small counties share a judge but keep their own clerk). File in the county where the defendant lives or does business, or where the claim arose; with several defendants, any one defendant's county works.
