Tracing is a procedure in English law used to identify property (such as money) which has been taken from the claimant involuntarily or which the claimant wishes to recover. It is not in itself a way to recover the property, but rather to identify it so that the courts can decide what remedy to apply. The procedure is used in several situations, broadly demarcated by whether the property has been transferred because of theft, breach of trust, or mistake. Tracing is divided into two forms, common law tracing and equitable tracing. Common law tracing relies on the claimant having legal ownership of the property, and will fail if the property has been mixed with other property, the legal title has been transferred to the defendant, or the legal title has been transferred by the defendant to any further recipient of the property. Equitable tracing, on the other hand, relies on the claimant having an equitable interest in the property, and can succeed where the property has been mixed with other property. Defences to tracing are possible, particularly if returning the property would harm an innocent defendant, where the claimant has made false representations that the defendant relied on to his detriment, or where the property has been transferred to an innocent third party without anything given to the defendant in return that the claimant could recover in lieu.
