About Chambers and Partners

Its researchers investigate law firms and lawyers globally through an exhaustive process of interviewing clients and competitors in major areas of business law. The Chambers Latin America guide covers a total of 19 jurisdictions, spanning Mexico, Central America, the Caribbean, and all Spanish and Portuguese-speaking countries in South America.
