A short recap of some of the key disclosure cases from the second half of 2025.

Disclosure is a dynamic and constantly evolving area of law, technology, and practice. Parties are grappling with ever-growing volumes of data and increasingly complex sources, while case law continues to highlight the legal and practical challenges involved. At the same time, these decisions offer valuable guidance for planning and mitigating risks in advance.

Our Disclosure and Evidence Management team distils the key developments in their biannual Disclosure Update reports, providing clear insights into the latest cases and trends.
