If this did not occur in Missouri, or the defendant did not live in Missouri at the time, you can not file suit in Missouri, small claims court or otherwise. Even if all occurred in Missouri, the claim of $7,000 exceeds the jurisdiction of the small claims court in Greene County. You must hire an attorney to file suit in Circuit Court or Associate Circuit Court and will not be able to use small claims court.
