Here in the US small claims court is limited to a few thousand dollars in damages depending on state. Anything larger than that is handled in civil court vice criminal court, which seems to be the distinction you were looking for, although civil cases can have juries as well. Hey, on the bright side having no clue how the justice system works at least means you've never had to participate in it!whether the dispute is $1000 or 1 million it's heared by a Judge only , there is no jurors for fraud or contract disputes. it's 'contract dispute' unlike murder, robbery, theft. robbery is you didn't agree to anything and was forced to hand over the money by force.
