Wisconsin legal malpractice insurers have published a breakdown of legal malpractice claims. Here, reported by Bonnie Shucha in the University of Wisconsin blog, are the most commonly sued for mistakes:
Calendaring – 23%
Failure to know or properly apply law – 14%
Planning error in choice of procedures – 13%
Inadequate discovery & investigation – 12%
Failure to obtain consent/inform client – 6%
Why calendaring? It is the easiest to see. Calendaring mistakes lead to dismissals for failure to appear, which is sublimely easy to comprehend and explain to a judge/jury.
