Financial Sanctions — Our Services
Investigations and Enforcement

Members of the Team advise those at risk of possible investigations for suspected breaches and advice those subject to either OFSI or NCA investigations. It is often the case that those investigations will either be in conjunction with overseas investigations where there are cross – border issues and where it is imperative for the client to have one international outcome for all alleged wrongdoing.

The team has extensive experience of such investigations in high profile cases but also brings its substantial experience in defending serious and complex crime and regulatory investigations and prosecutions in other areas of white-collar crime law. Similarly, financial sanctions berach cases inevitably also concern alleged money laundering breaches and offences and our considerable experience in that area enables us to give comprehensive advice across all relevant issues.

Our notable experience
  • Complex Trust structures (owned by a high-profile Russian Oligarch) in Jersey, Isle of Man and the Cayman Island on potential exposure arising from the EU, UK and US Sanctions regimes.
  • Acting for a high-profile individual in the UK who is facing an OFSI investigation and parallel OFAC and DOJ investigations for alleged sanctions breaches.
  • Advising trust companies navigating suspected sanctions breaches and working alongside trusted overseas partner law firms on the same issues.
  • Advising a whistle-blower on sanctions breaches in conjunction with US advisers concerning a DOJ criminal investigation.
