I’m not a lawyer but an advocate with about 30 cases on the go at any time and about 50 to 60 cases per year. Only a third of these end up in litigation (med/arb). I’ve been reading this thread with great interest but unfortunately I still can’t decide: one DB with groups for matters or many DB ? Lots of good points raised on both sides of the divide.
