This book provides an extensive analysis of the equitable doctrine of marshalling as it applies to secured debt. There is detailed and systematic reference to the application of marshalling in the United Kingdom, in particular the conditions that must be satisfied before marshalling will assist a secured creditor and the limitations imposed on its effective operation. There is also substantial comparative material, with extensive analysis of Commonwealth law and selected US authorities. This book will appeal equally to those specialists working in equity, finance and insolvency law and to commercial lawyers more generally.
