This new book is devoted to the law of assignment and looks at the transfer of a species of property known as choses in action (e.g. a debt, share or a patent). Historically, tangible personal property - particularly, land - has been regarded as economically the most significant, and assignment has not received the analytical and practical treatment that it merits. However, assignment of intangible property is a gowth area of practice and this book fills an important gap in the market for specialist treatment of this difficult area.
