When Do I Get My Evidence Back?
The documents that are marked and received into evidence as exhibits are part of the record of the hearing and cannot be returned while an appeal is pending.
For this reason, you should bring extra copies of documents you wish to have marked as exhibits. Unless the original copy is necessary, photocopies may be marked. But be sure to bring the original to verify that no alterations have been made to it.
You may request that the original exhibit be returned to you when the decision becomes final. See special rules for telephone hearings and documentary evidence in Do I Need To Send Anything In Before The Hearing?
