An expert witness, professional witness or judicial expert is a witness, who by virtue of education, training, skill, or experience, is believed to have expertise and specialised knowledge in a particular subject beyond that of the average person, sufficient that others may officially and legally rely upon the witness’s specialised (scientific, technical or other) opinion about an evidence or fact issue within the scope of his expertise.
Expert witnesses may also deliver expert evidence about facts from the domain of their expertise. An expert witness is someone who is recognised by a court as an authority on a topic who has knowledge beyond that accessible to the average person. In order to be accepted as an expert witness, the witness must generally present his or her qualifications on the stand so that the judge and jury understand what sets the witness part from other witnesses. Rather than testifying on legal matters, expert witnesses provide factual information and analysis which may be beneficial to a case.
