International Expansion & Lateral Integration
Launching two European offices under pressure — and making both commercially viable from day one
When a leading UK law firm expanded into Europe, it faced two very different integration challenges at once: one office built through confidential lateral partner hires, the other through merger with an established local team. Both had to launch fast, operate smoothly, and build momentum immediately.
The Challenge
Opening new offices is never just an operational exercise. In this case, success depended on integrating senior partners under conditions that made conventional onboarding almost impossible.
Confidential recruitment restricted meaningful pre-hire access to incoming partners
Merger integration required balancing an existing team’s identity with firmwide governance
Both offices had to be operational, connected, and client-ready from day one
Timelines were highly compressed, leaving little room for slow relationship-building
What We Did
A tailored integration strategy was designed for each office, recognising that confidential lateral recruitment and merger integration require fundamentally different approaches.
For the greenfield office, the focus was on accelerating connection from a standing start: structured onboarding, targeted leadership introductions, and early alignment on values, collaboration, and strategy.
For the merger office, the focus was on trust, transparency, and alignment: managing expectations alongside Heads of Agreement negotiations, facilitating cultural integration, and ensuring full systems readiness for immediate participation in global client work.
“What looked like an office launch challenge was, in reality, a partner integration challenge.”
Results
Two European offices launched on time and fully operational
Incoming partners became commercially active immediately
Integration friction and post-hire risk were significantly reduced
A repeatable integration playbook was created for future expansion
