WLA Co-Practice Corridor

US to Europe.
The world's highest-
volume corridor.

The US-Europe corridor generates more cross-border legal work than any other in the world. M&A in both directions, technology regulatory divergence, employment complexity for transatlantic workforces, and tax structuring in a post-Pillar Two world. WLA co-practices both sides simultaneously.

How co-practice works on this corridor

Not two firms.
One co-practice
team.

WLA co-practice means both the local legal expert on this side AND on the other side jointly hold the client matter under one WLA Institutional framework. The client deals with one team — not two separate firms passing a referral.
