Among the four mechanisms of discipline and regulation of legal professionals identified by David Wilkins, liability controls have received almost no attention from scholars who study legal professions. This paper presents a comparative analysis of what is known about lawyers’ professional liability drawing on reports concerning a group of 13 countries representing every continent. The discussion covers three topics: the frequency of LPL claims; the areas of practice that produce LPL claims; and insurance requirements and arrangements for compensating those who successfully bring an LPL claims. The analyses show that empirical information is available for only a small subset of the countries considered, but what is available shows very substantial variation in both the frequency of claims and the areas of practice producing those claims. Insurance requirements and arrangements also vary substantially, with LPL insurance being mandatory in only about half of the countries.
