This paper by Canadian attorney Jeff Simser explores the use of civil recovery tools to chase suspect wealth across borders (primarily non-conviction based (NCB) forfeiture, also known as civil asset forfeiture). NCB forfeiture allows a state to freeze and confiscate the proceeds and instrumentalities of unlawful activity on a civil balance of proof. While not universally enacted, NCB forfeiture is increasingly available for states to untangle and attack laundered assets.
