In 2003, the first international agreements on justice and home affairs were signed by the EU. Both agreements came into force on February 1, 2010. The EU and US framework agreements facilitate and accelerate aid between the EU and the US. The EU has extradition and mutual legal assistance agreements with the United States of America as well as Japan, Iceland and Norway. The mechanisms of mutual legal assistance will gradually be replaced by instruments of mutual recognition. However, an agreement between EU countries remains: the Convention on Mutual Legal Assistance in Criminal Matters strengthens cooperation between judicial, police and customs authorities. For example, the Convention on Official Administrative Assistance in Tax Matters is a convention that facilitates the conclusion of bilateral agreements for the exchange of tax information between more than 90 States Parties. The EU-Japan agreement on mutual legal assistance in criminal matters establishes modern instruments of cooperation, such as videos and the exchange of banking information. In addition to MLATs, the United States has a Mutual Legal Assistance Agreement (MLAA) with China, as well as an MLAA between the American Institute of Taiwan and the Taipei Economic and Cultural Representative Office in the United States.

The United States has also concluded a number of executive recovery cooperation agreements, including an agreement with the United Kingdom providing for consumer aid and asset allocation in drug cases; an expiry agreement with the Kingdom of the Netherlands; and an agreement on drug forfeiture with Singapore. The United States has asset-sharing agreements with Canada, the Cayman Islands (extended to Anguilla, the British Virgin Islands, Montserrat and the Turks and Caicos Islands), Colombia, Ecuador, Jamaica, Mexico and Monaco. A Mutual Legal Assistance Contract (MLAT) is an agreement between two or more countries to collect and exchange information, in order to enforce public law, including criminal law. A rogatory commission is often used to formally question a suspect in criminal proceedings when the suspect resides in a foreign country. Mutual legal aid contracts (MLATs) generally allow the exchange of evidence and information in criminal cases and related matters. In case of money laundering, they can be extremely useful in obtaining bank and other data from our contractors.
