Book excerpt: The law of tracing is a complex subject which has struggled to find a home in works on property, equity, commercial law and restitution. Broadly speaking, it addresses the question of when rights held in an asset can be asserted in another asset despite changes in form or attempts to 'launder' the initial asset. Properly understood this area of study is composed of several distinct topics. This book explores all the areas covered by the law of tracing in a degree of detail not previously reached in more general works.
