The document discusses the doctrine of privity in contracts. It states that under the common law, only parties to a contract can enforce rights or obligations under that contract. However, there are exceptions that allow non-parties to circumvent this rule in certain situations. It then examines some of these exceptions in detail, including: actions by promisees, establishing oneself as a party to the contract, situation-specific exceptions recognized by courts, estoppel, agency relationships, and assignments.
