In many Chicago divorce or Chicago custody cases there are no witnesses called by either party. If the dispute between the parties is complex or contentious, however, witnesses could be involved. Witnesses can be fact witnesses or expert witnesses. Fact witnesses, as the name implies, testify to facts. Expert witnesses may testify to facts and also may give their opinions regarding a relevant issue. Because of their training, licensing or certification and experience, expert witnesses possess knowledge on a particular subject that exceeds that of most people. Thus, the opinion of expert witnesses assist the court in deciding how to rule on a contested issue.
