Our partner Yves Klein will be contributing to the sessions on the Identification of Assets as part of INSOL International’s new Short Course in Asset Tracing and Recovery

Running from 1 October 2025 to 31 March 2026, this six-month online course is designed to equip professionals with 5+ years’ experience in Restructuring, Insolvency, or AssetRecovery with advanced strategies for identifying, tracing, preserving, and recovering assets — including digital and crypto assets — in today’s complex Cross-border environment.

Yves will contribute to Sessions 2 & 3: Identification of Assets, where he will cover key topics such as:

  • Tracing and profiling assets before bringing legal applications, including scenarios with no obvious assets to enforce;
  • Practical considerations and legal remedies across different jurisdictions;
  • Using insolvency tools and preventive measures to secure assets;
  • Mandatory and ad hoc disclosures, preservation applications, and the effects of commencing insolvency proceedings;
  • Comparative insights from the UK (common law) and the Netherlands (civil law), as well as perspectives on offshore jurisdictions.

 

He will be joined by fellow instructors Angela Barkhouse (Kroll, Cayman Islands), Ros Prince (Stephenson Harwood, UK), Antonia Mottironi (Ardenter Law, Switzerland), and Chris Parker (DLA Piper, UK).

Together, they will explore practical strategies and legal tools for identifying and preserving assets in cross-border insolvency and fraud cases. Topics will include asset tracing methodologies, disclosure mechanisms, jurisdictional considerations, and comparative insights from common and civil law systems.
