Smart contracts can define AND ENFORCE the transfer of smart property without intervention. The world of smart property today is limited to digital currency. But if you "skate where the puck is going" it's not hard to imagine other digital goods being smart-property-enabled and eventually physical things like cars, door-locks etc. A smart contract CAN incorporate a digital sign-off from third party verifiers. But it's not always necessary nor is it a defining feature. God's mercy notwithstanding.
