Transatlantic litigation
Penningtons Manches Cooper’s transatlantic litigation practice has a particular specialism in handling and successfully resolving transatlantic disputes. Our team coordinates strategy across multiple jurisdictions, advising on the underlying proceedings as well as handling enforcement of judgments and arbitral awards. Renowned for their deep sector experience, knowledge of the US courts, and established relationships with US and Canadian law firms, our specialists act as trusted advisors across the many challenges of transatlantic dispute resolution.
Expert guidance on transatlantic disputes
Managing multi-jurisdictional litigation: we are regularly instructed on matters requiring strategic advice across a range of issues and jurisdictions, including managing litigation in the English courts as well as acting as corporate counsel in the US State Appeal and Supreme Courts and the US Federal and Federal Appeal Courts. Our lawyers work closely with trusted local counsel while maintaining an overview of strategic global objectives. Clients receive practical guidance on risk, cost and settlement implications and options. Our team also frequently advises on – and, where necessary, obtains – interim relief to preserve assets and evidence.


Reciprocal enforcement and recognition: we assist with the recognition and enforcement of US judgments in England and – where appropriate – with challenges to enforcement. Our lawyers’ in-depth knowledge of asset tracing and investigatory options ensures clients can identify the most effective route to recovery. Working with US counsel, we help structure US litigation and damages awards to maximise their enforceability in the UK. We also advise on settlement structures and security arrangements to enhance recovery prospects.
Excellent … a strong commercial sense in seeking to achieve the clients’ litigation objectives; and also a very good understanding of US litigation.
Serving foreign proceedings and obtaining evidence: serving US proceedings in the UK – and vice versa – can pose significant challenges in transatlantic litigation. We have extensive experience of the legal framework, understand the procedural and practical pitfalls to avoid, and have an excellent track record in effecting service efficiently and defensibly. Our lawyers also regularly obtain evidence for use abroad, advising on disclosure strategies, third-party material and applications for letters of request.
