-For a seized document to be admissible as evidence, it is necessary to prove it is the same document seized and is in the same condition as it was when seized. Because several people may handle it in the interval between seizure and trial, it should be adequately marked at the time of seizure for later identi- cation. and its custody must be shown from that time until it is introduced in court. - Investigators or auditors who seize or secure documents should quickly identify them some marking, so they can later testify that were when documents seized and that they are in the same condition as they ized. Investigators might, for instance, write their initials and the date of seizure on the margin. in a corner, or at some other inconspicuous place on the front or back of each document. If circumstances suggest that such marking might render the document subject to attack on the grounds that it has been defaced or it is not in the same condition as when seized. the investigators or auditors can, after making a copy for comparison or for use as an exhibit the report, put the document into an write a description and any other identifying information on the front of the envelope, and seal it.
