The instruction for advice or assistance, and accompaning material, provided to the barrister is called a “brief”. A solicitor may have one or more of a number of reasons for choosing to brief (that is, provide a “brief” to) a barrister. The solicitor may be too busy to do the work connected with preparing for, or in, court. More often the barrister is briefed because the solicitor need helps and the barrister has expertise in a particular area or is a specialist advocate.
