Privity of contract

Privity of contract

The relationship between the parties to a contract, and the rule that follows from it: only the parties to a contract can enforce it, and only they are bound by it. A third party who is not a party generally cannot sue to enforce the contract’s terms, even if the contract benefits them, and cannot be made liable under it.

Privity is a common law doctrine. This entry explains it from the US and English perspective, where the rule and its exceptions developed differently, with a short note on civil law at the end.

Meaning of privity of contract

“Privity” comes from the Latin privatus (private) and describes a private, direct legal relationship. Two parties who sign a contract with each other are “in privity”. Anyone else is a third party, sometimes called a stranger to the contract.

The doctrine has two sides:

1. No rights for third parties. A person who is not a party cannot enforce the contract, even if it was made partly for their benefit.
2. No obligations for third parties. Two parties cannot impose a contractual obligation on someone who did not agree to it.

The second side is uncontroversial: nobody should be bound by a deal they never made. The first side is the one with many exceptions, because it can defeat what the parties actually intended. Privity is separate from the question of whether the contract itself is valid, which depends on the elements of an enforceable contract.

Where the doctrine comes from

Two English cases are the usual starting points:

• Tweddle v Atkinson (1861): two fathers agreed with each other to pay a sum of money to the son of one of them on his marriage. When one father’s estate did not pay, the son sued and lost. He was not a party to the agreement, so he could not enforce it.
• Dunlop Pneumatic Tyre Co v Selfridge & Co (1915): Dunlop sold tyres to a dealer, who resold them to Selfridge under a contract containing a minimum price. Selfridge sold below that price. The House of Lords held that Dunlop could not enforce the price term against Selfridge, because there was no contract between them.

US law moved away from the strict rule much earlier. In Lawrence v. Fox (New York, 1859) the court allowed a creditor to enforce a promise made to his debtor to pay him, which became the root of American third-party beneficiary law.

Exceptions to privity of contract

Intended vs incidental beneficiaries (US)

Under US law the question is whether the contracting parties intended to give the third party a right to enforce the promise. A life insurance beneficiary, or a creditor whom the parties agreed to pay directly, is an intended beneficiary. A neighbour whose property value rises because a developer contracted to build a park next door is merely incidental and has no claim.

The Contracts (Rights of Third Parties) Act 1999 (England and Wales)

The Act reformed English law for contracts made after it came into force (Scotland has its own legislation). Section 1 lets a third party enforce a term if the contract expressly provides for it, or if the term purports to confer a benefit on that party, unless on a proper reading of the contract the parties did not intend the term to be enforceable by them. The third party must be identified by name, as a member of a class or by description, but need not exist when the contract is made.

Many commercial contracts in England exclude the Act with a short clause, for example: “A person who is not a party to this agreement has no right under the Contracts (Rights of Third Parties) Act 1999 to enforce any of its terms.” If the parties want a group company or a customer’s affiliates to have enforceable rights, they need to say so expressly.

Examples of privity of contract

• Subcontractors. A homeowner contracts with a builder, who hires a subcontractor. The subcontractor cannot normally sue the homeowner for payment, and the homeowner cannot normally sue the subcontractor for breach of the builder’s contract. Each claim runs along the chain of contracts. Construction projects often fix this with direct warranties or step-in rights. See a subcontractor contract template for how the chain is documented.
• Group companies. A parent company signs a software licence, and its subsidiaries use the software. If the licence does not grant the subsidiaries rights, they may not be able to enforce service levels themselves.
• Gifts by contract. A customer buys a product as a gift. The recipient may lack a contractual claim against the seller, depending on the jurisdiction, although product liability and warranty statutes often help.

Privity of contract vs privity of estate

In leases, a second relationship exists: privity of estate, which links the current landlord and the current tenant through the land itself. When a tenant assigns a lease, the new tenant is in privity of estate with the landlord, while the original tenant may remain liable through privity of contract unless the landlord releases it or statute says otherwise. Whether and how far original tenants stay liable differs between jurisdictions.

Why privity matters for contract drafting

Privity decides who can actually enforce the deal you have written. When drafting or reviewing a contract, check:

• Who are the parties? Use full legal names. A contract signed by the wrong group entity may leave the right entity without a claim.
• Should anyone else have rights? Affiliates, customers, end users and lenders only get enforceable rights if the contract or the applicable law gives them.
• Can the contract be transferred? The assignment and subcontracting clauses decide whether rights can move to a buyer or financier, and whether work can be passed down a chain.
• Has the right party signed? The person signing must have authority to bind the party. See signing authority for how that works.

Keeping the parties, their signatories and the contract’s key data in one place makes these checks quick. In fynk, parties and metadata such as contract owners and values are stored as structured fields for every contract.

A note on civil law

German and Austrian law have no doctrine of privity in the common law sense. They allow contracts in favour of third parties directly: in Germany, § 328 BGB lets the parties agree that a third party may claim performance. The basic idea that a contract cannot impose obligations on an outsider still applies.

Frequently asked questions

• What is privity of contract in simple terms?

  It means a contract is a private relationship between the people who made it. Only they can enforce it and only they are bound by it. Outsiders generally cannot sue under it or be sued under it.

• What are the main exceptions to privity of contract?

  Third-party beneficiary rules in the US, the Contracts (Rights of Third Parties) Act 1999 in England and Wales, agency, assignment, novation, collateral contracts, and claims in tort such as negligence or product liability that do not depend on a contract.

• Can a third party sue for breach of contract?

  Only if an exception applies. In the US the third party must be an intended beneficiary. In England and Wales the contract must expressly give them the right or purport to confer a benefit on them, and the parties must not have excluded the 1999 Act.

• Why is privity of contract important?

  It decides who can enforce a contract and who is bound by it. It protects outsiders from obligations they never agreed to, and it forces parties to state clearly if they want someone else to have rights under the contract.

• Does privity of contract apply in the US?

  Yes, as the default rule, but US law has recognized enforceable rights for intended third-party beneficiaries since the 19th century, and product liability law largely removed privity as a barrier for injured consumers.
