A sneaky, underhanded lawyer is a pettifogger. If your neighbor hires an unscrupulous quack to sue you, you might call his attorney a pettifogger. You don't hear the word pettifogger much these days, since the word is fairly archaic, but you might come across it in an old book.

Or someone who is widely read, the term is hardly recondite.
