Business Attorney – The role of a corporate lawyer is to ensure the legality of commercial transactions, advising corporations on their legal rights and duties, including the duties and responsibilities of corporate officers. In order to do this, they must have knowledge of aspects of contract law, tax law, accounting, securities law, bankruptcy, intellectual property rights, licensing, zoning laws, and the laws specific to the business of the corporations that they work for. In recent years, controversies involving well known companies such as, Walmart and General Motors have highlighted the complex role of corporate lawyers in internal investigations, in which attorney-client privilege could be considered to shelter potential wrongdoing by the company.  If a corporate lawyer’s internal company clients are not assured of confidentiality, they will be less likely to seek legal advice, but keeping confidences can shelter society’s access to vital information. 
The practice of corporate law is less adversarial than that of trial law. Lawyers for both sides of a commercial transaction are less opponents than facilitators. One lawyer (quoted by Bernstein) characterizes them as “the handmaidens of the deal”. Transactions take place amongst peers. There are rarely wronged parties, underdogs, or inequities in the financial means of the participants. Corporate lawyers structure those transactions, draft documents, review agreements, negotiate deals, and attend meetings.
