Queen's Counsel

n. Q.C., official lawyer of the British crown during the rule of a queen

K.C., official lawyer of the King, advocate of the King

Queen's Counsel (postnominal QC), during the reign of a male sovereign known as King's Counsel (KC), are lawyers appointed by letters patent to be one of "Her Majesty's Counsel learned in the law"; the position exists in various Commonwealth countries around the world. They do not constitute a separate order or degree of lawyers. They are, however, more than merely a professional rank, as their status is conferred by the Crown and recognised by the courts. In order to "take silk" (i.e. become one of Her Majesty's Counsel) one generally has to serve as a barrister or a Scottish advocate for at least 10 years. Recently solicitors have also been appointed Queen's Counsel.
