Since the Mutual Legal Assistance Treaty with the U.S. came into effect in 1986, the two governments have cooperated in some 230 requests for assistance under the Treaty, resulting in successful law enforcement actions. Assets seized under such actions have been both shared by the U.S. and the Cayman Islands under an asset-sharing agreement as well as returned to the U.S. for restitution to victims of fraud and other crimes.
The Cayman Islands was the first regionally, and among the first worldwide, to criminalise the laundering of the proceeds of all serious crimes, extending such legislation beyond the scope of drug-money laundering.
