An advocate is someone who speaks on behalf of another person, especially in a legal context. It is used primarily in reference to the system of Scots law, Anglo-Dutch law, Scandinavian and Israeli law, and also to refer to the fused legal professions in the Channel Islands and Isle of Man. Implicit in the concept is the notion that the represented lacks the knowledge, skill, ability, or standing to speak for themselves. The broad equivalent in many English law-based jurisdictions is "barrister".
