This book examines property issues in respect of intermediated securities under English law, namely title and title conflicts between a true owner and a purchaser. Intangible book entry securities held with an intermediary, often commingled with the holding of other clients of the intermediary, often give rise to uncertainty in property rights in the securities of an investor under most legal systems, for example, whether property rights can be established and how title conflicts are dealt with. The general property law implications of intermediated securities and responses of national laws and international uniform law are examined. English property law and trusts law are investigated to identify their mechanisms of recognising property rights. Title conflicts in respect of chattels, certificated bearer securities, and certificated registered securities, are examined to identify the underlying policies and mechanisms. Priority rules across legal and equitable property rights are reviewed to explore their application to title conflicts in respect of intermediated securities as legal and equitable title. Solutions to title conflicts of national laws and international uniform law are exposed as a basis for seeking a better solution for English law.
