A lawyer (also called attorney, counsel, or counselor) is a licensed professional who advises and represents others in legal matters.  Seven years of education following high school is typically required to obtain a law degree: four years of undergraduate school and three years of law school.  You must graduate from an ABA-accredited law school with a Juris Doctor (J.D.) degree and pass a 3-day bar exam in order to become a member of the bar.  In law, the bar is the legal profession as an institution.
