Without assuming prior legal knowledge, books in the Directions series introduce and guide readers through key points of law and legal debate. Questions, diagrams and exercises help readers to engage fully with each subject and check their understanding as they progress. This chapter examines the privity rule, which states that only a party to the contract can sue upon it. It discusses the development of the privity rule, distinguishing the privity rule from the consideration rule, evading the privity rule, techniques for giving a right directly to a third party or apparent third party, specific performance in favour of a third party and damages for a third party’s loss, and the Contracts (Rights of Third Parties) Act 1999.
