From my experience working at a top ten law school, Admissions will overlook the word max sometimes.  It all depends on how strong of a canidate you are.  If they love everything about you, they will look pass that, but if they are a little iffy about you, and not sure if they will accept you or not, they will look at the little things like going over a word max.  If the school states they have a max, there ususally is a reason, aka having to read thousands of essays in a short time.  My first, second drafts were well over 1,800, but after a month or so, and many revisions I was able to narrow it down to a 1,000 word, and a 500 word version.  The 500 word version was by far the better of the two, as it was direct and to the point, but still got the messages across.
