The English law of contribution and reimbursement is essentially concerned with any situation where two parties must both pay a debt to a third party, compensate him for harm that he has suffered at their hands, or restore an enrichment which they have unjustly gained at his expense. Thesesituations give rise to questions of how the parties' common liability should be shared and how their relationships with the third party, and with one another, should be adjusted so as to ensure that they each pay their proper share. This book is based on the rules of English law which determine theanswers to these questions.Contribution and reimbursement claims often arise in the course of complex multi-party litigation and the rules which govern their determination are scattered through the law reports and statute books. This book provides a clear guide through this maze of legislation and case law, and gives adetailed account of all the substantive and procedural rules in the area. It is an essential source of information for legal practitioners and academics seeking practical advice on this notoriously complex subject.
