Allen & Overy’s (A&O) flexible legal services business known as Peerpoint has increased the number of lawyers on its books by more than 50 percent in the past year and now plans to launch it in New York and Frankfurt, as the firm looks to expand the service around the world.

The service, which was launched in London in 2013, draws on a bank of contract lawyers—referred to as consultants—to assist clients on projects during periods of high demand.
