In 2014, the firm moved to its home at 1301 Avenue of the Americas. Prior to 2014, the firm had been located at 30 Rockefeller Plaza, where it occupied eight floors. The firm moved to Rockefeller Plaza from its original Wall Street home in 1973 in order to become more accessible to its national and international clients. An even earlier “move” occurred in 1935 when it formed one of the first branch offices of a New York law firm in Washington, DC. Beginning in 1990 in Moscow, Chadbourne established offices in England, Poland, Ukraine, and Kazakhstan, receiving a significant boost in its Eastern Europe network from the dissolving firms Altheimer & Gray and Coudert Brothers. In March 2008, the firm acquired the Mexico City office of the New York firm Thacher Proffitt & Wood as well as an associated team of lawyers in New York focusing on Latin America-related arbitration and transactions. Its newest offices opened in São Paulo, Brazil and Istanbul, Turkey respectively. The firm also has a small satellite office in China.
