This would be written into the order itself. If there is no expiration date, it is permanent.
It depends on the order. It should be specified in the text of the order.
Court orders last forever unless there is a specified ending date, time, age, etc. and it depends on the type of case too.
if it is a final restraining order...it lasts forever...have fun never seeing the girl u love again.
The expiration date will be listed in the order. It can be for any period of time.
