The Regulatory Policy Institute was commissioned by the Legal Services Board (LSB), supported by the Law Society, to undertake a study of possible barriers to (a) entry, (b) exit, and (c) changes in the business structures of regulated solicitors’ firms/practices in England and Wales; and the findings of this study are set out in what follows. The focus of the work is, as was requested, on small solicitors’ practices, with particular attention given to the consideration of barriers to change that might either be caused or exacerbated by current regulatory arrangements, or that might be amenable to reduction via modification of those arrangements.
