Request law school applications from the schools that interest you. Don't forget most law school catalogs may be viewed in FAC 5. Work on your recommendations first. Faculty are asked to write lots of recommendation letters. Be sure to carefully read each law school's application process.
Some law schools have their own forms to complete and require confidential recommendations.
Level with professors. If they can't, move on. If you have been out of school for a long time, you can use past employment supervisors, but you will still need at least one faculty recommendation. Ask the T.A. to write the letter and to include both signatures. Prepare your references.
