An attorney would need to read the order that was issued to see if it expires. Alternatively, if you read through the order and you are still unsure as to whether the order expires, you can call the court that issued the order and ask them.
I agree with Ms. Gujavarty.
Additionally, it would be unusual for a Temporary Order to have an expiration date. Instead, if the case becomes dormant, the court will set it for dismissal. If it is dismissed, then the Temporary Order dies with it, and the case reverts back to the last final order of the court.
