This is one in a series of books seeking to introduce the reader to the more frequently encountered common law principles which apply in Hong Kong. This book presents an introduction to contract principles. Contracts affect everyone, from simple daily activities as buying groceries to more complicated and formal agreements such as renovation. As a basic version intended for general use, this publication aims to be an overview. The organizational structure reflects this goal: the text is kept short and easy to read (with Chinese translations of most legal terms used in the text) while the extensive endnote section provides much more comprehensive and detailed explanations for those readers who seek such information. The Table of Contents conveniently provides an overview in an outline format of the subject. The extensive Index makes the book more user-friendly.
