I bought this dictionary 4 years ago and since then it has been invaluable to me in getting through law school and the bar exam. My copy is so tattered and worn out, I'm thinking of buying a new one to replace it. I highly recommend it over Black's and others that have traditionally been regarded essential for law students and lawyers. Too often with the other legal dictionaries, you look up a word, and then to understand the given definition you end up having to look up additional words. Not so with this book--it lays out legal definitions in the most simple and straightforward manner possible. For many terms, it even gives short hypotheticals to illustrate the term in its proper context.
Even though it's titled "For Non-Lawyers" I highly recommend this book to law students, lawyers, paralegals, and anyone else who might appreciate legal jargon explained in an easily understandable way.
