It becomes apparent from an analysis of cases and law that many jurisdictions, when using the term malpractice, limit the term strictly to physicians and surgeons. It is not so much the fact that legal malpractice is excluded from the term malpractice but rather that it is never even mentioned. Since legal malpractice appears to be a matter of state definition it would seem that perhaps the best approach to understanding legal malpractice would be to examine (as typical) the statutes of three of our leading states, to see what is the present status of their laws on the subject.
