This is kind of interesting: from Lawyers Weekly
Legal mal practice cases are continuing to grow. Some verdicts: A $225 million award to a securities broker who sued his lawyer for missing the deadline to opt out of a class-action lawsuit. The verdict included $221 million in punitive damages; $108 million, including $75.3 million in punitive damages, against a sole practitioner for mishandling a divorce case; $55.2 million against a firm for bad advice on a bond deal; $18 million, including $16.4 million in punitive damages, against a lawyer who advised two sisters they did not owe taxes on an inheritance.
However, the vast majority of legal mal practice cases do not make it to court. Lawyers don't want the bad publicity so
settle before going to court.
