An "advocate" is a professional in the field of law. Different countries and legal systems use the term with somewhat differing meanings. The broad equivalent in many English law–based jurisdictions could be a barrister or a solicitor. However, in Scottish, Manx, South African, Italian, French, Spanish, Portuguese, Scandinavian, Polish, Israeli, South Asian and South American jurisdictions, "advocate" indicates a lawyer of superior classification.

A barrister is a type of lawyer in common law jurisdictions. Barristers mostly specialise in courtroom advocacy and litigation. Their tasks include arguing cases in courts and tribunals, drafting legal pleadings, researching the law and giving legal opinions.
