London-based Mischon de Reya, which opened a New York office in 2010, is poised to halve the size of its partnership in the Big Apple.

The decision, which comes after a review by Mishcon of its business in the city, will see the number of partners drop from six to three. Overall lawyer head count in the office—the British firm’s only outpost in the U.S.—has also fallen by three to 12.
