A boutique law firm is a collection of attorneys typically organized in a limited liability partnership or professional corporation specializing in a niche area of law practice. Although a general practice law firm includes a variety of unrelated practice areas within a single firm, a boutique firm specializes in one or a select few practice areas. There may be some confusion as legal publications may refer to any small- or mid-sized firm as a boutique, though generally firms with fewer than 100 attorneys would count. Boutique should apply to those firms that focus on particular areas, regardless of size, though they are typically smaller, with exception to a few firms such as Finnegan, Henderson, Farabow, Garrett & Dunner or Fish & Richardson with over 400 attorneys.
Mid-size law firms began losing ground in the 1980s in the consolidation of the legal market. They have been the primary means by which larger law firms from regional centers expanded in key new markets such as New York City. For example, Atlanta-based Alston & Bird acquired 50-lawyer German-focused corporate boutique Walter, Conston, Alexander & Green, P.C. in 2001. The same year, Boston-based legacy firm Bingham Dana & Gould (now known as Bingham McCutchen) merged with boutique litigation shop Richards & O'Neill and Dallas-based Jenkens & Gilchrist absorbed Parker Chapin Flattau & Klimpl. Recently, Texas firm Vinson & Elkins acquired Cronin & Vris, a small bankruptcy boutique.
The pendulum began to swing back away from consolidation toward the formation of smaller boutique firms with the downturn of the economy in late 2008 and early 2009 as recession-proof niche practices began to separate themselves from the struggling behemoths. For example, Washington, D.C.-based Hautsfeld LLP spun out of Cohen Milstein and Birmingham, Alabama-based Frohsin & Barger, LLC spun out of the southern regional firm Baker Donelson. Both Hausfeld and Frohsin & Barger have been cited as examples by the National Law Journal as "somewhat recession-proof" boutiques. Other boutiques, such as Waesche, Sheinbaum & O'Regan, have dissolved.
