This is the first work specialising on director's duties and liabilities to be written from the perspective of the UK Companies Bill. It focuses on issues of present day practical importance. The work covers all issues relating to directors from the requirement to have directors and their functions through to a discussion on their appointment and removal. The newly formulated directors' duties are discussed in detail. There is full coverage of topical issues such as director's terms of service and chapters dedicated to giving practical guidance on claims against directors by the company, members and during insolvency proceedings. Criminal proceedings are also considered as are liabilities of directors to third parties. This major work provides essential guidance for practitioners advising directors, members and companies on the conduct of directors.
