Houthoff Class Action Survey Update: key developments across 16 jurisdictions

6 January 2026

Class actions remain a significant concern for many of our clients. As societies become more complex, so do the legal disputes that arise within them. Five years after our first Class Action Survey in 2019, we published an extensive update in 2024 in partnership with 11 leading law firms, covering key trends in 12 jurisdictions.

As we begin 2026, we are expanding the survey further, introducing a concise executive version and extending its scope to 16 jurisdictions and law firms. We will share these updates, including emerging trends and recent developments, in stages leading up to the Morais Leitão & Houthoff Class Actions Seminar on 13 February in Lisbon, hosted at the offices of Morais Leitão. The seminar will present the full set of insights and is tailored for legal counsels and board members of corporations that could potentially be targeted by class actions. Participation is by invitation only. To secure your invitation, please contact Isabella Wijnberg.

Below, you will find the latest chapters as they become available, each accompanied by a downloadable PDF.
