Using legalese when speaking to a jury can kill your chance to win. Since the jury can’t understand the words you are speaking, its members are unlikely to reach the conclusions you want them to.
The author writes: "Most professionals speak and write in language unique to their profession. That isn’t usually a problem when lawyers are communicating with lawyers (although it is less effective than plain English.) But when a lawyer needs to communicate effectively with a jury, legalese creates serious problems not only because the jurors do not know what your legalese means, but, even worse, because some of them think they know what some of these terms mean—but they don’t."
