This well-established and respected textbook has been relied upon by students and academic scholars for nearly 50 years. Praised for the clarity of the writing, the comprehensive scope of the content and the high level of critical analysis, Professor Philip Pettit builds on the strengths of the book to offer students a rigorous and yet readable account of equity and trusts law. The basic structure of the previous edition has not been substantially altered. The diagrams introduced in the 11th edition have been well received and have been retained, as has the glossary. There has been some rearrangement of matters within chapters which will, it is hoped, clarify the exposition. Online Resource Centre Three additional chapters can be accessed on the Online Resource Centre: Conversion and Reconversion; Satisfaction, Ademption and Performance; and The Equitable Doctrine and Election. Along with the chapters appearing in the 12th edition, these chapters have been updated to reflect changes in the field.
