This Practice Note compares the key characteristics of pursuing a fraud claim either by way of a civil claim or a private criminal prosecution, including identifying the contrasts between the two procedures. It therefore considers: jurisdiction, limitation, publicity and media interest, control of the litigation and decision making, the length of the proceedings, the selection of charges (criminal) or heads of claim (civil), the standard of proof, investigation and evidence gathering, pre-action considerations, the preservation of assets using urgent and interim orders, the privilege against self-incrimination (right to silence), disclosure during the proceedings, defences and counterclaims, costs, non-financial and financial outcomes (prison sentences, damages, confiscation and compensation) and enforcement. It serves as a summary reference guide for practitioners who are considering the options for their client of either pursuing a civil claim for fraud or a private prosecution (or potentially both in parallel). For general guidance on civil fraud claims see: Civil fraud—overview and in particular: • Practice Note: Civil fraud—heads of claim • Practice Note: Starting a civil fraud claim—a practical guide
