[11th November 1999]

Be it enacted by the Queen’s most Excellent Majesty, by and with the advice and consent of the Lords Spiritual and Temporal, and Commons, in this present Parliament assembled, and by the authority of the same, as follows:—
Act in force at Royal Assent (11.11.1999): for application see s. 10(2)(3)
Act extends to Northern Ireland but the operation of s. 9 is limited by application as mentioned in s. 9(1)

1 Right of third party to enforce contractual term.
(1) Subject to the provisions of this Act, a person who is not a party to a contract (a “third party”) may in his own right enforce a term of the contract if—
(a) the contract expressly provides that he may, or
(b) subject to subsection (2), the term purports to confer a benefit on him.
(2) Subsection (1)(b) does not apply if on a proper construction of the contract it appears that the parties did not intend the term to be enforceable by the third party.
(3) The third party must be expressly identified in the contract by name, as a member of a class or as answering a particular description but need not be in existence when the contract is entered into.
(4) This section does not confer a right on a third party to enforce a term of a contract otherwise than subject to and in accordance with any other relevant terms of the contract.
(5) For the purpose of exercising his right to enforce a term of the contract, there shall be available to the third party any remedy that would have been available to him in an action for breach of contract if he had been a party to the contract (and the rules relating to damages, injunctions, specific performance and other relief shall apply accordingly).
(6) Where a term of a contract excludes or limits liability in relation to any matter references in this Act to the third party enforcing the term shall be construed as references to his availing himself of the exclusion or limitation.
(7) In this Act, in relation to a term of a contract which is enforceable by a third party—
“the promisor” means the party to the contract against whom the term is enforceable by the third party, and
“the promisee” means the party to the contract by whom the term is enforceable against the promisor.

2 Variation and rescission of contract.
(1) Subject to the provisions of this section, where a third party has a right under section 1 to enforce a term of the contract, the parties to the contract may not, by agreement, rescind the contract, or vary it in such a way as to extinguish or alter his entitlement under that right, without his consent if—
(a) the third party has communicated his assent to the term to the promisor,
(b) the promisor is aware that the third party has relied on the term, or
(c) the promisor can reasonably be expected to have foreseen that the third party would rely on the term and the third party has in fact relied on it.
(2) The assent referred to in subsection (1)(a)—
(a) may be by words or conduct, and
(b) if sent to the promisor by post or other means, shall not be regarded as communicated to the promisor until received by him.
(3) Subsection (1) is subject to any express term of the contract under which—
(a) the parties to the contract may by agreement rescind or vary the contract without the consent of the third party, or
(b) the consent of the third party is required in circumstances specified in the contract instead of those set out in subsection (1)(a) to (c).
(4) Where the consent of a third party is required under subsection (1) or (3), the court or arbitral tribunal may, on the application of the parties to the contract, dispense with his consent if satisfied—
(a) that his consent cannot be obtained because his whereabouts cannot reasonably be ascertained, or
(b) that he is mentally incapable of giving his consent.
(5) The court or arbitral tribunal may, on the application of the parties to a contract, dispense with any consent that may be required under subsection (1)(c) if satisfied that it cannot reasonably be ascertained whether or not the third party has in fact relied on the term.
(6) If the court or arbitral tribunal dispenses with a third party’s consent, it may impose such conditions as it thinks fit, including a condition requiring the payment of compensation to the third party.
(7) The jurisdiction conferred on the court by subsections (4) to (6) is exercisablein England and Wales by both the High Court and the county court and in Northern Ireland by both the High Court and a county court.

3 Defences etc. available to promisor.
(1) Subsections (2) to (5) apply where, in reliance on section 1, proceedings for the enforcement of a term of a contract are brought by a third party.
(2) The promisor shall have available to him by way of defence or set-off any matter that—
(a) arises from or in connection with the contract and is relevant to the term, and
(b) would have been available to him by way of defence or set-off if the proceedings had been brought by the promisee.
(3) The promisor shall also have available to him by way of defence or set-off any matter if—
(a) an express term of the contract provides for it to be available to him in proceedings brought by the third party, and
(b) it would have been available to him by way of defence or set-off if the proceedings had been brought by the promisee.
(4) The promisor shall also have available to him—
(a) by way of defence or set-off any matter, and
(b) by way of counterclaim any matter not arising from the contract,
that would have been available to him by way of defence or set-off or, as the case may be, by way of counterclaim against the third party if the third party had been a party to the contract.
(5) Subsections (2) and (4) are subject to any express term of the contract as to the matters that are not to be available to the promisor by way of defence, set-off or counterclaim.
(6) Where in any proceedings brought against him a third party seeks in reliance on section 1 to enforce a term of a contract (including, in particular, a term purporting to exclude or limit liability), he may not do so if he could not have done so (whether by reason of any particular circumstances relating to him or otherwise) had he been a party to the contract.

4 Enforcement of contract by promisee.
Section 1 does not affect any right of the promisee to enforce any term of the contract.

5 Protection of promisor from double liability.
Where under section 1 a term of a contract is enforceable by a third party, and the promisee has recovered from the promisor a sum in respect of—
(a) the third party’s loss in respect of the term, or
(b) the expense to the promisee of making good to the third party the default of the promisor,
