To edit a case, go to that case's screen and click 'edit' next to the case's name. 

This brings up the edit case modal. Here you can adjust case fields like Plaintiff and Defendant name, and archive the case.

Archiving a case will preserve all of the case data and transfer it to a secure and redundant offline storage solution.  Archived cases do not apply towards your usage limits, but they can take from 3 to 5 hours to restore if you need to access them again.

Next: Edit a Deposition.
