Although international arbitration boutique practices barely existed a decade ago, there are now dozens of international arbitration boutiques law firms throughout the world.

A boutique law firm is a specialized legal practice composed of experts in a certain field of law. The cost of their legal services may be more competitive than those of large international corporate firms, and they tend to know their legal niche very well.

International arbitration boutiques focus solely on disputes capable of being resolved via arbitration and mediation, although some practices call themselves boutique arbitration practices while primarily practicing other fields of law.

Boutique arbitration practices are often based in cities that are popular seats of arbitration, such as Paris, London or Geneva. Most boutique practices provide legal representation for clients in any jurisdiction, however, so firms in Geneva, Paris or London often serve as legal counsel for arbitrations with their seat in Singapore or New York and the opposite is also true. As international arbitrations take place via correspondence except for during oral hearings, which typically last one or two weeks (and are increasingly likely to take place online), there is rarely a need for clients to use a boutique arbitration practice located in a given location.

Some arbitration boutiques are just emerging on the market or are in fact sole practitioners. Other arbitration boutiques such as Aceris Law, Hanotiau & van Den Berg and Three Crowns are larger and better-established.
