An expert witness must satisfy certain requirements before they are able to testify in a United States federal court.  The expert must have technical, scientific and/or other specialized knowledge that can help the jury understand specific parts of the testimony. They can even testify using their opinion if it is a product of reliable principles and they have been applied to the facts of the case and that their opinion is based upon sufficient facts and/or data.

The responsibilities of an expert witness could be any of the below or a combination:

~ Consultant to lawyer
~ Issue a pre-trial affidavit
~ Testify at trial

Generally, expert witness fees are paid according to time involved not their testimony. This “time” covers many tasks an expert witness is required to accomplish during the course of an investigation. Some of these are: phone calls, meetings, visiting the accident site, speaking with lawyers, reviewing evidence, evaluating the information provided, and sometimes travel time. Usually the actual time on the witness stand is only a small percentage of the expert witnesses’ total fee.
