Gray's Inn [SEP] Introduction
The Honourable Society of Gray's Inn, commonly known as Gray's Inn, is one of the four Inns of Court (professional associations for barristers and judges) in London. To be called to the bar and practise as a barrister in England and Wales, a person must belong to one of these inns. Located at the intersection of High Holborn and Gray's Inn Road in Central London, the inn is both a professional body and a provider of office accommodation (chambers) for many barristers. It is ruled by a governing council called "pension", made up of the masters of the bench (or "benchers"), and led by the Treasurer, who is elected to serve a one-year term.
