It is advisable to familiarize yourself with the views and opinions that your expert witness has expressed in previous cases for two reasons. 1) Earlier opinions may serve to strengthen your case and 2) opposing counsel may ask the expert about these opinions. For example, the medical expert witness may have relevant experiments, exhibits, case studies, etc. from earlier cases that may affect their testimony. Questions you will ask on direct examination should be rehearsed with the expert and you may want an associate to cross-examine them. When dealing with difficult subject matter, have the expert review how he will explain technical concepts to the jury.

Multimedia Expert Witness Testimony
When your expert witness’s work is very detailed and not amenable to oral argument, a report may be useful. For example, the multimedia expert witness may be asked to opine on text, audio, still images, animation, video, and/or electronic media devices. Since multimedia involves the convergence of text, pictures, video, and sound into a single form, conveying content and information to a jury about multiple forms may not lend itself to oral argument. A possible solution is to convert the expert’s testimony into a report that may be presented in an electronic format to be used as a presentation in court.
