At least some (sections of) legal documents are incomprehensible because they refuse (probably for legal reasons mind you :-) to use mathematical notation. In a sense the need to keep them accessible to a generally but not mathematically literate audience is precisely what turns them incomprehensible. Describing logical and mathematical relations in words is taxing the reader, thats why these notations where invented! A related but different issue applies to any form of supporting visual explanation, despite the lack of a cognitivive barrier (nb: assuming accessibility). The word must be the beginning and the end, otherwise it opens the door for disputes.
