For 30 years, The Legal 500 has been analysing the capabilities of law firms across the world. Now, with the Private Practice Powerlist, The Legal 500 initiates a new series identifying key individual practitioners with outstanding specialization in, and knowledge of, particular jurisdictions. Given the broader political context, the US-Mexico focus of this first Private Practice Powerlist could not be more timely: the lawyers named here will undoubtedly have a crucial role in what appears likely to be a relatively abrupt re-calibration of US-Mexico relations, particularly in the area of (bi-national) trade….read more

Future editions of the Private Practice Powerlist will, in a similar manner, seek to identify groups of key specialists with expertise in relation to other significant and critical jurisdictions.

Research of the Private Practice Powerlist has involved the canvassing of opinion from law firm partners and in-house counsel alike, as well as analysis of the career trajectories of the candidates considered for inclusion, so as to permit the identification of those practitioners with an engagement in the Mexican market that goes beyond just occasional involvement. In the undoubtedly complex, and quite possibly uncomfortable, process of bi-national re-accommodation that the US and Mexico are now facing, it is to this group of lawyers that we can look for the expertise to ameliorate the impact of the transformation. As such, they will be crucial in ensuring the continuity of business integration developed over the 20-plus years since the enactment of the North American Free Trade Agreement in 1994.

Our team of experienced researchers has assessed the candidates, analyzing both current practice and historical data to confirm the inclusion of individual practitioners. The US-Mexico Private Practice Powerlist includes not only highlights reflecting the work of the attorneys who have made the final list, but also future-facing commentary indicating – as far as is possible in such a fluid scenario – which legal and industrial sectors they perceive as likely to remain active despite the recasting of bi-national relations. Certainly, it is these individuals who will be the quiet protagonists that ensure business (and indeed, public entities and sub-sovereigns) continue to find the constructive and creative practical resolutions required to overcome the obstacles that arise during the forthcoming period of change.

GC Powerlist: Nigeria 2026

On 26 February, Legal 500 returned to Lagos to launch the latest edition of the GC Powerlist: Nigeria, hosted at the exclusive Metropolitan Club and attended by more than 100 senior in‑house lawyers from across the country. The evening brought together many of Nigeria’s most influential corporate counsel for a programme that blended recognition, thought leadership and high‑level networking in a setting that reflected the prestige of the series. Honourees were celebrated for the impact they have made within their organisations, their contributions to the wider legal ecosystem and their ability to drive innovation and strategic value across sectors ranging from finance and energy to technology and consumer markets.

The event opened with remarks from David Freeman, Global Business Development Manager at Legal 500, who spoke about the significance of the GC Powerlist in Nigeria and the evolving role of in‑house counsel as strategic leaders. He highlighted the growing influence of general counsel in shaping governance, regulatory engagement and business transformation, setting a purposeful tone for the evening.

The programme continued with insights from two distinguished speakers. Adedoyin Afun, Partner at Bloomfield, offered a forward‑looking analysis of Nigeria’s regulatory and transactional landscape, noting the increasing pressures and opportunities facing in‑house teams as they navigate compliance shifts, cross‑border transactions and the expectation to operate as commercial partners. He was followed by keynote speaker Angela Omo‑Dare, retired General Counsel of Stanbic IBTC Group, whose reflective address on leadership, ethics and the long‑term development of legal teams resonated strongly with the audience. Drawing on her extensive career, she underscored the GC’s role as an ethical steward, culture‑shaper and trusted adviser to senior leadership.

After the formal proceedings, guests enjoyed dinner and continued discussions on emerging trends shaping the Nigerian legal landscape, from regulatory reform and investment flows to legal operations and talent development. The atmosphere remained warm and engaged throughout, reinforcing the sense of community that has become synonymous with the GC Powerlist.

Overall, the GC Powerlist: Nigeria 2026 launch event ultimately reaffirmed Legal 500’s commitment to celebrating and elevating the work of general counsel in one of Africa’s most dynamic markets. With its combination of high‑calibre speakers, strong industry representation and meaningful recognition, the event stood out as a defining moment in the 2026 calendar and further strengthened the platform’s role as a convening force for leadership and professional excellence within Nigeria’s in‑house legal community.

Legal 500 extends its sincere thanks to Bloomfield Law for its invaluable support of this year’s publication.
