Law schools will also want to see letters of recommendation sent on your behalf.  These letters are used by admission committees to further ensure that you are a good candidate for law school.  You'll notice that I didn't say "recommending you as someone who would make a fine attorney".  There is a big difference.  Remember, you are applying to be a law student, not a lawyer.  The admission committees know very well that it is nearly impossible to predict who will be a good attorney.  Further, admission committees are in the law school business.  They are looking for folks who have the potential to be successful law students.  Your personal statements should be designed around exhibiting your capacity to be a successful law student and your recommendations statements should do the same.
    Some of your recommendations may turn out to be from academic types who are well seasoned with writing recommendations in support of law school candidates.  Others, however, may not have a clue as to how to fashion a recommendation for you.  I can think of no reason why you should not submit to such a recommender a list of your accomplishments and characteristics exhibiting amenability to success in law school.  After all, you should, by that time, have a good idea of what you would like the admission committee to hear about you. 
    I'm not suggesting you write your own recommendation.  I am suggesting that if a recommender is dragging their feet, or looking for guidance as to what to write, you might submit to them a list of your characteristics and accomplishments that are noteworthy.  With deadlines approaching you can't have untimely recommendations throwing a wrench into your admission plans.
    Before you provide any guidance to a recommender, you should consult the catalog for the law school the recommendation is to be sent to be sure there are no provisions prohibiting such activity.
