Washingtonian's Best Lawyers list is based primarily on peer reviews and recommendations from thousands of attorneys who were asked to name top practitioners in their field and whom they would hire to represent them. Clients, judges and former judges also commented. The 2013 list includes 1,000 lawyers from 30 practice areas who practice in the District of Columbia, Maryland and Virginia.
