Apropos of this post, this chart from Minnesota Lawyers Mutual shows the number of malpractice claims according to years of experience. As you can see, lawyers with 10+ years of experience produce far more malpractice claims per policy than lawyers with fewer years of experience.
There are a few caveats. First, this doesn’t show ethics complaints. Also, the occurrence of an ethics complaint or a malpractice claim may or may not correlate to competence. And there are a number of reasons why lawyers with more experience (and therefore, a longer “tail” of clients) should have greater malpractice exposure. But what I think it is fair to say, based on this chart, is that new lawyers aren’t getting into hot water out of proportion to older lawyers.
