  Jan Erik Windthorst



Erik represents clients before state courts, arbitral tribunals and government agencies. He handles banking and finance litigations as well as corporate disputes (including M&A and joint venture litigations, disputes about long-term agreements and corporate law conflicts). His matters  often have a cross-border element. Erik also has extensive experience with internal and administratively imposed investigations. He has led numerous enquiries in the financial sector and other industries. He knows the client perspective in this area from a secondment to the Litigation and Regulatory Enforcement team of a leading international bank.

Erik advises clients from a broad range of sectors, among them notably financial institutions (investment and corporate banks) and companies from the technology, energy, insurance and private equity sectors.

Erik publishes regularly and is recognized by leading legal directories: JUVE’s Handbook Commercial Law Firms in Germany lists him as "frequently recommended" for dispute resolution, citing others who describe Erik as a “lightning-quick strategist” (JUVE Handbook 2017), “creative, highly professional” and someone who “has full control over the proceedings” (JUVE Handbook 2018). Legal 500 Germany singled Erik out as ‘name of the next generation’ for financial litigation (2018) and “Who’s Who Legal” selected him in the law firm partner category as a “Future Leader” in arbitration.
