No. The number is permanent and nothing renews.
Because we sell the application and nothing else. The filing itself is an afternoon of a lawyer's time, done in batches, and the checks are automated before she sees a case.
It happens when a document is not what it should be, and the checks catch that before we file. If it still cannot be filed, you get the money back.
