I work in quite a small jurisdiction (Hong Kong, with around 1,550 practising barristers and 11,470 practising solicitors).
England & Wales is obviously much larger jurisdiction and I have begun to notice a number of highly specialised roles (e.g. private prosecution practices) there.
One of the practice areas I find the most fascinating is in the area of legal costs. It seems there are at least 3 roles (the first two of which seemingly overlap): law costs draftsman, costs lawyers, costs barristers. There are even KCs specialising in costs!
How did the division of roles (and market share) arise? Is it simply the case that (generally) the barristers side serve more high-value contentious cases, and the law costs draftsman/costs lawyers do more of the preparatory work?
I have come across this blog post from 2010, which basically says the costs bar arose because the law became more complex and costs arguments got more technical.
Really curious to learn from English litigators who can shed light on this!
