To mark the launch of its Europe 2026 Guide, Chambers hosted a webinar bringing together senior researchers and leading in-house counsel to discuss key trends shaping the legal market.

The session featured Maria Barras, Chief Legal and Public Affairs Officer at Booking.com, and Lance Barthouw-Amius, General Counsel and Head of Legal Affairs Service at UNHCR, who shared their perspectives on how the role of in-house counsel is evolving, as well as their expectations of external law firms.

If you were unable to attend, we have summarised the key takeaways below.

Research overview

Chambers highlighted the continued growth in engagement across its research process.

Across all guides, more than 64,500 submissions were received, alongside over 90,000 interviews and more than 265,000 survey responses. For the Europe 2026 Guide specifically, over 11,500 submissions were received, with the final rankings including 1,645 law firms and 14,812 lawyers. In total, more than 13,700 interviews were conducted.

As highlighted during the webinar, it is this depth and consistency of research that allows Chambers to produce an accurate, year-on-year reflection of the legal markets it covers.

Updates to the Europe Guide

This year’s guide also includes several structural updates across jurisdictions.

In the Netherlands, Corporate M&A has been divided into three value-based tables. In Italy, standalone Litigation and Arbitration sections have been introduced, while in Spain, the Tax category now includes elite and higher regarded sub-tables.

All practice areas were reviewed based on the sophistication of work, team depth, client feedback and overall quality of service.

The evolving role of General Counsel

A key theme throughout the discussion was the increasing influence of in-house legal teams.

Maria Barras noted that, in both Europe and the US, between 70% and 85% of General Counsel now report directly to the CEO. This shift reflects the growing importance of legal within organisations and its closer alignment with business leadership.

She also highlighted a significant change in the composition of legal teams. Departments are becoming more multidisciplinary, incorporating a wider range of expertise beyond traditional legal roles. In her own team, approximately half are lawyers, while the other half include professionals from areas such as data, compliance and policy.

This reflects a broader shift in how legal departments operate, with responsibilities spanning value protection, business enablement and industry leadership.

Legal as a strategic function

The webinar also emphasised the increasingly strategic role of legal teams within organisations.

General Counsel are now more actively involved in leadership discussions and strategic planning. Being part of these conversations allows legal teams to contribute earlier in the decision-making process, helping shape strategy rather than simply reviewing it at a later stage.

This approach also helps position legal teams as enablers of the business, supporting execution rather than being perceived as a barrier.

The impact of AI

AI was another major focus of the discussion, with in-house teams already exploring its potential.

Maria Barras described how her team is actively experimenting with different tools and approaches, noting that this remains a period of exploration. She highlighted several key learnings:

• The importance of ongoing experimentation at both individual and team level
• The need to balance broad experimentation with focused, department-wide progress
• The role of AI in enhancing quality, not just improving efficiency
• A shift towards rethinking entire workflows, rather than simply automating individual tasks

Overall, AI was described as a catalyst for change, encouraging legal teams to rethink how they operate.

Expectations of law firms

The session also provided clear insight into what in-house counsel expect from external law firms.

Maria Barras emphasised the importance of receiving advice that supports decision-making, rather than advice that is overly cautious or difficult to apply in practice. She also noted that law firms should invest time in understanding the broader context in which their clients operate, including business priorities and strategic objectives.

Proactivity was another key theme. Law firms are expected to provide insights based on their wider market experience, helping clients understand how similar challenges are being addressed elsewhere.

More broadly, there is an expectation that law firms work closely with in-house teams, operating as a single, integrated team.

AI and law firms

AI is also shaping expectations of law firms.

From an in-house perspective, firms are expected to use these tools to improve speed of execution, deliver more data-driven insights and increase overall efficiency. At the same time, there is an expectation that firms are transparent about how AI is used and understand the associated risks.

The discussion also touched on the potential for AI to influence law firm business models, particularly in relation to pricing structures.

The UNHCR perspective

Lance Barthouw-Amius provided a perspective shaped by the unique environment in which UNHCR operates.

His team supports operations across multiple jurisdictions, often in complex and high-risk environments, where decisions need to be made quickly and based on imperfect information. This requires a highly practical, solution-oriented approach.

He highlighted several developments within his team, including increased legal sophistication, a growing focus on technology and AI, and stronger collaboration with law firms and private sector partners.

Working with law firms

From UNHCR’s perspective, strong partnerships with law firms are built on shared values and collaboration.

A genuine pro bono commitment is an important factor, but the focus is also on working together on matters that are strategically important. Law firms are expected to bring their full expertise to these engagements and to work as long-term partners.

Ongoing communication and feedback are also key to maintaining effective working relationships.

Final thoughts

The webinar highlighted how the role of in-house counsel continues to evolve.

Legal teams are becoming more influential, more integrated into business strategy and more open to new ways of working. As a result, expectations of law firms are also changing.

For firms looking to strengthen their position in legal directories, these insights provide a clear indication of what matters most to in-house clients today.
