Sometimes, a case may require a party to instruct a barrister/counsel to handle the case. The party may seek professional advice from his lawyer:
whether he should further instruct a barrister/counsel
the likely fees
This may be necessary when the case comes out to be complex in terms of facts or laws. The legal fees to a barrister/counsel varies significantly. The relevant factors are the seniority of the barrister/counsel and difficulty of the case. A senior counsel (shortly known SC) may require a professional fee of 1/3 to 1/2 of a million dollars. This is called "brief".
