Expert witnesses are specialists in their respective fields that provide advice and assistance to attorneys. Consulting with an expert witness is something best left to your attorney. There are many aspects of trial that only a qualified attorney should deal with and the selection of an appropriate expert for your case is one of them. An expert witness generally has extensive experience in a particular subject, may be published in technical or professional journals, may have certain degrees, memberships or other qualifications. An expert witness is not an advocate for one side or another, they are independent of the attorney. Unlike any other witnesses, experts can present their opinions to the court.
