Although many kinds of people working in or studying legal affairs are referred to as lawyers, the word really describes a person who has become officially qualified to act in certain legal matters because of examinations he has taken and professional experience he has .Most countries have different groups of lawyers who each takes a particular kind of examination in order to qualify to do particular jobs. In Japan, a lawyer must decide whether he wants to take the examination to become an attorney, a public prosecutor or a judge. In England, the decision is between becoming a barrister or a solicitor. Barristers specialize in arguing cases in front of a judge and have the right to be heard, the right of audience, even in the highest courts. They are not paid directly by clients, but are employed by solicitors.
