Corporate lawyers are tasked with safeguarding the legality of commercial transactions, representing corporations and advising corporate employees on their legal duties and responsibilities. Because corporate law covers a broad range of topics, corporate lawyers often specialize in one or more areas. These areas include tax law, bankruptcy, intellectual property, zoning or securities. Most corporate lawyers work for a corporation, but some are self-employed or work for a law firm. Some law school graduates become educators, investment bankers or leaders of non-profit organizations.
