Lawyer is a man or a woman licensed to represent people in a court of law or to counsel them on matters of law. He or she is also called an attorney, a counselor, or a solicitor. A person who seeks a lawyer's services is called a client. In the United Kingdom, a lawyer who has the right to argue cases in higher courts is called a barrister. The lawyer's duty is to make sure that all points of law and facts that favor the client's case are brought to the court's attention, and that justice is done.
