Any fact that is not proven through oral testimony is demonstrative evidence. Demonstrative evidence can be a document, a piece of physical evidence, a drawing, or a model. Exhibits are often duplicated, highlighted, excerpted, or blown up for easy visibility. The paralegal trial assistant is in charge of handling the physical exhibits. These responsibilities include arranging for any special equipment necessary to display the exhibit — easels, overhead projectors, or VCRs. This equipment is usually available in the courtroom, but a simple telephone call in advance of trial can save substantial consternation and delay once the trial begins.

The paralegal trial assistant's duties also include managing the exhibits offered by the opposing side. A court scheduling order usually requires the parties to exchange witness and exhibit lists in advance of trial. The exhibits listed must be compiled and available at a moment's notice during the trial. The exhibit is usually accompanied by notes of questions to ask about the exhibit, any legal challenges to the admissibility of the exhibit, and any related exhibits. Because the opponent's exhibits can be presented at any time through any witness, the organization of these exhibits is crucial.

A final exhibit task often assigned to the paralegal trial assistant is keeping track of the evidentiary status of each exhibit. Some exhibits are admitted without objection; some are admitted over objection; some are admitted for limited purposes; still others are admitted on a preliminary basis pending additional evidence; and some exhibits are never admitted. Knowing the evidentiary status of each exhibit can be extremely important for a later objection, argument, or motion.
