A barrister is a type of lawyer in common law jurisdictions who specializes in representing clients in court. They provide expert legal advice and advocacy, often focusing on specific areas of law. Barristers typically work independently and are usually hired by solicitors to represent clients in more complex legal matters. In many countries, barristers must complete additional training and be called to the bar, which is a formal process that allows them to practice in higher courts. They often wear distinctive robes and wigs during court proceedings, a tradition that dates back centuries.
