if it was expunged, you don't have to disclose
Once again, and I'll get down off of my soapbox, if the application states to include even items that have been expunged, you must include them....
Example, here's a direct excerpt from one law school application:
B: Have you ever been or are you currently a plaintiff, defendant, or other party in any civil or criminal proceeding; any administrative or alternative dispute resolution forum; any mediation or arbitration proceedings; any traffic-related proceeding (except for parking tickets).
__ Yes __ No If yes, please explain fully, including information regarding final disposition, or current status of the matter
(including probation, deferred adjudication or any other type of pretrial diversion) on a separate sheet. You must report incidents even if the record has been or will be expunged or sealed.
In this case, you must disclose. All of my apps required disclosure.
