Attorney

A person who has been qualified by a state or federal court to provide legal services, including appearing in court. Each state has a bar examination which is a qualifying test to practice law. Graduation from law school does not make one an attorney.

(may be referred to as a practitioner or representative) - an individual who is a member in good standing of the bar of any United States court or the highest court of any State and who is registered to practice before the Office.
