There are different types of lawyers that specialize in different areas of the law. Many of these lawyers are trained to research, review and present cases to the judicial system to ensure their clients are represented properly. Although some lawyers go to trial to present their cases, there are lawyers that work behind the scenes to assist other attorneys with building their cases. Large corporations will normally hire a staff of lawyers to work on cases that are filed against their companies.
