29th April 2026
HKA’s Paris leadership recently spoke with Décideurs on the rapidly evolving litigation and arbitration landscape, highlighting the firm’s accelerating growth in France and the intensifying debates around expert evidence.
In the wide‑ranging conversation, Patrick Hébréard, Matthias Cazier‑Darmois, Florent Myara and Jean Salloum explore how Paris has become a strategic pillar in HKA’s international development, driven by increasing demand for high‑quality financial, economic and forensic expertise in complex disputes.
They discuss a market marked by greater technical sophistication, tougher cross‑examinations and heightened scrutiny of expert methodologies. These are trends that are reshaping expectations of expert witnesses across arbitration and judicial proceedings alike.
The interview also examines the growing role of forensic investigations, data analytics and artificial intelligence, as well as the emergence of third‑party funding as a factor broadening access to justice.
Together, these developments underline the importance of integrated, cross‑disciplinary expertise in today’s disputes environment.
