Largest Legal Companies in the World

We have a long list, compiling the largest legal companies in the world. These companies are said to be big not because of their building structure but because of their reputation and feat in the world of laws and justice.

Unarguably, the law is a big service-based business. Business, finance, taxation, litigation, corporate affairs, conflicts, patents, copyrights, antitrust, property, labor, arbitration, as well as administration, political, and social matters all require law expertise.

While there are other criteria to rank law firms—such as revenue per partner or lawyer, the number of lawyers, or year-over-year percent growth—annual revenue remains the most accurate, consistent, and easy to follow. The United States of America has always been on the top ten list of countries with the largest legal companies or firms in the world.

Studies say that eight of the largest legal companies in the world have a headquarters based in the U.S., with only one of them—Clifford Chance—having its headquarters overseas. Dentons has no centralized headquarters, but has the most lawyers and offices located in China.
