Huh. Anecdote: I got divorced about five years ago. My ex's attorney was so lazy/ incompetent/ etc. that she let him go. During the finalization of things, I pointed out that in at least two filings, her attorney was so inept that I went from being the the respondent to being plaintiff about half way through the filings. And another clause was about division of commingled property that we'd never owned (and that seemed obviously cut and pasted from another client).

Those were decreed to be "honest mistakes", and not the result of negligence or malpractice.
