An examination for individuals who want a license to practice law. Typically, bar exams are multiday tests of endurance and knowledge, covering a wide range of legal topics. Once licensed in a particular state, an attorney can practice law in that state and in federal courts in that state. Some states require a special bar examination for attorneys who have already passed the bar in other states, while others recognize out-of-state attorneys if they have established local residence. Lawyers from one state may occasionally practice in another with the consent of the court alone.
