This book is designed to provide a comprehensive examination of the concept of subrogation in Marine International Law. It is a system wherein underwriters indemnify the assured and then seek to recoup from the party liable. This work aims to analyse the principles of subrogation and to critically examine the implementation of the doctrine in the marine international world. This study is focused on marine insurance as distinct from non-marine insurance. As marine insurance is international in nature and cuts across national boundaries and jurisdiction, comparisons is made between the common law and civil jurisdictions. As such, the domestic law of the United Kingdom which is reputed to be the leader in insurance, and that of other jurisdictions such as the United States of America. This work above all seeks to propose ways that would ease the difficulty which the insurers encounter in exercising their rights of subrogation.
