At least 20 international law firms were operating in Moscow before Russia invaded Ukraine in February, setting off waves of Western sanctions. Some firms are closing their Moscow offices due to the invasion, while others have said they are still considering their next steps, including the future of their work for Russian clients.

Norton Rose Fulbright said this week it will close its 15-lawyer Moscow office “as quickly as we can, in compliance with our professional obligations.” The firm said it was reviewing its relationships with clients connected to the Russian government.

Cleary Gottlieb Steen & Hamilton said it is temporarily shutting down operations in Moscow, “pending further developments.” It is also ending its representation of Russian government and state-owned entities and complying with sanctions, the firm said.

Debevoise & Plimpton said it was “conducting a review of the status of our Moscow office.” The firm said it would not take on any new clients in Moscow and has terminated some client relationships.

Baker Botts said it was “actively examining” its future in Russia.

Baker McKenzie, said it was “reviewing and adjusting our Russia-related operations and client work.”

Dechert is “currently reviewing our presence in Moscow,” a firm spokesperson said.

Hogan Lovells said it is able “to continue to operate our Moscow office.” The firm said it was continually evaluating its operations and its work in light of new laws and sanctions.

White & Case said its Moscow office is open but it is no longer representing certain Russian and Belarusian clients.
