A lawyer, attorney at law, or attorney, is a professional who is licensed to practice law in a given area or jurisdiction. To “practice law” generally means to represent a client before a court of law, or to give legal advice. Attorneys perform many tasks and provide many services in the course of their everyday work. Some attorneys may practice in a wide range of areas of the law; others may only specialize in a few or only one area. Attorneys can work in groups (such as in a law firm), with a partner, or by themselves in a solo practice.
