White Collar and Financial Crime

Kingsley Napley has been expert in the field of white collar crime and fraud defence for more than 50 years.  The firm has an unrivalled reputation and one of the largest, most experienced and respected teams in the City.

We act for companies and individuals subject to investigation and prosecution by agencies including the Serious Fraud Office (SFO), City of London Police, Crown Prosecution Service (CPS), Financial Conduct Authority (FCA), HM Revenue and Customs (HMRC), Insolvency Service and the Competition and Markets Authority (CMA).  Some of our lawyers have worked for these organisations in the past, so have knowledge of the process from both sides of the fence. We are also regularly instructed in multi-jurisdictional investigations conducted by overseas agencies such as the US Department of Justice (DoJ) and FBI. We also act as independent legal advisers for witnesses.

Our Services

Kingsley Napley can assist at all stages of the criminal defence process, from arrest, detention, interviews under caution or attendance at compelled interviews, to conducting internal investigations, advising whether to self-report to the authorities, negotiating settlements right through to supporting clients during criminal trials.

Fraud audit

Our Regulatory and Criminal law teams can help law firms manage their risk arising from the new 'failure to prevent fraud' corporate criminal offence created by the Economic Crime and Corporate Transparency Act 2023 (ECCTA).

Under this legislation, from September 2025 a large organisation is criminally liable if:

• A specified fraud offence is committed by an employee, agent, or other 'associated person' for the organisation's benefit.
• The organisation did not have 'reasonable' fraud prevention procedures in place.

We will comprehensively review the effectiveness of your procedures and policies to prevent fraud, including your risk assessment and control framework. Our final report will contain an assessment of your compliance with government guidance, and tailored advice on any actions that should be taken.

 

money laundering

The UK’s anti-money laundering (AML) regime is amongst the most stringent. We represent both individuals and organisations in AML matters. Find out more about how our lawyers can help.

Whether allegations of criminal wrongdoing are against a company or an individual we understand the pressures and consequences involved. Clients want a trusted adviser who can identify the best strategy, mount a robust defence and guide them through the process.

Our experience spans the most high-profile cases in recent years  through to advice on matters less in the public eye, and covers work for corporates and individuals in cases involving  allegations of bribery and corruption, fraud or tax evasion as well as associated proceeds of crime issues.

Increase in investigations

Despite the well-rehearsed resourcing issue within UK law enforcement agencies, investigations into serious white collar, fraud and corporate criminal offences are on the increase. Without exception, the relevant agencies have extensive legislative and enforcement powers at their disposal, not to mention ambitious enforcement plans, making them forces to be reckoned with.  

We help clients navigate through the intricacies of the legislation that underpins criminal enforcement action: not just the various offences, but also the rules governing the conduct of investigations, such as those concerning search and seizure and disclosure, where the origins of successful defences are often found. We also have an in-depth knowledge of agencies’ priorities and current focus. What really sets us apart, however, is our skill in providing both strategic and practical advice which helps us to secure the best possible outcome for our clients.
