For over 25 years, The Legal 500 has been analysing the capabilities of law firms across the world. In a new series, The Legal 500 is turning its attention to the in-house function, and recognizing those corporate counsel who are driving the legal business forward. Up first is the Corporate Counsel 100: United States, which identifies the most powerful corporate legal advisers in the United States.

We have canvassed opinion from our 2.5 million in-house readers and partners at law firms across the US, to bring you the 100 in-house stars that are driving the profession. The selection criteria is based on those corporate counsel who are changing or forming opinions within their company or industry; have developed brilliant technical solutions to complex issues; created innovative structures to ensure that the in-house function is driving the business forward; provided a diversity or business working model that other corporate counsel should follow.
