Corporate and Financial Crime — Our Services
In a fast-evolving, global environment, where penalties for any breach are severe and the need to bring timely challenges is crucial, our sanctions team provides specialist advice, backed by worldwide experience.

We have significant global experience working on sanctions and related investigations and have been involved in navigating the sanctions regimes in a range of countries, including Russia, Iran, Myanmar, North Korea and Syria.

Our team has advised a number of high-net-worth clients facing the consequence of sanctions laws and regulations, challenging their designated status and navigating through complex licencing issues before authorities such as OFSI, OFAC and other European regulators. We have also advised clients who face sanctions breach investigations by domestic and overseas authorities including the US and Jersey.

Our practice also includes advisory work, assisting clients across several industries including the financial services, retail, commodities telecommunications and transport, addressing possible exposure under domestic and international sanctions regimes covering the United Nations, the UK, the US (in combination with trusted partner law firms) and the EU.
