International Crime and Extradition

"substantial expertise in cross-border cases involving allegations of bribery and corruption, tax fraud, money laundering and insider dealing, amongst other issues, and the firm is also adept at dealing with investigations and prosecutions brought by various institutions."

Legal 500, 2017

Criminal law is increasingly international. Actions taken by a person in one country may become the subject of an investigation in another, with the risk of this leading to an extradition request or European Arrest Warrant (EAW).  Businesses and individuals may find themselves the subject of entirely unexpected enquiries and requests from investigators from other jurisdictions.

In some cases, attempts may be made to compel testimony for proceedings in other countries, or an individual's extradition may be sought.   Some criminal offences, such as corruption offences and certain war crimes and associated allegations, can be prosecuted in a country that has little or no connection to the place where the offences are alleged to have occurred.

We are often asked to advise and represent foreign nationals in police investigations, also advising the relevant embassies where necessary.

The way in which a person or business responds to a request from a foreign jurisdiction may have profound consequences.  Knowing what your rights are and understanding the options from the beginning is essential to achieve the best result.

Whether facing a request for Mutual Legal Assistance (MLA), an extradition request or investigation or prosecution in the UK for an offence occurring overseas, our lawyers have the knowledge and experience to help.

Kingsley Napley is rated as a Band 1 firm for Crime and Extradition by Chambers UK.  We have a superb international reputation and a key network of international lawyers with whom we work  on extradition, mutual legal assistance requests and international investigations into offences such as corruption, cartels, fraud and money laundering.

Financial Sanctions and Export Controls

Our expert lawyers can advise in the event of a criminal investigation or prosecution for a breach of sanctions and for individuals who have been made the subject of sanctions or restrictive measures. We also represent companies and individuals regarding trade control issues.


Kingsley Napley has a wealth of experience in successfully defending extradition requests having worked in this field for several decades.

Crimes of Universal Jurisdiction

Travel to the UK can occasionally bring about unexpected consequences. There are a range of criminal charges that can be faced by non UK nationals even though the alleged criminal acts may have occurred abroad and may not involve the UK in any way.


An Interpol Red Notice can severely inhibit a person’s liberty, and have drastic consequences for a person’s reputation. We can assist in Red Notice cases by engaging with Interpol either prior to or following the issue of a Red Notice.

Business and Human Rights

Consumers and regulators increasingly expect companies to demonstrate a commitment to human rights, where companies fall short, they increasingly face both reputational and legal consequences.

Jurisdictional Issues

The team at Kingsley Napley is experienced in acting for companies who are subject to criminal investigation and prosecution either by multiple domestic or else by domestic and overseas agencies.

Mutual Legal Assistance

Robustly defending requests from foreign jurisdictions is not for the faint-hearted or inexperienced. Our lawyers are recognised leaders in the field.
