Common law exceptionsEdit
There are exceptions to the general rule, allowing rights to third parties and some impositions of obligations. These are:
- Collateral Contracts (between the third party and one of the contracting parties)
- Trusts (the beneficiary of a trust may sue the trustee to carry out the contract)
- Land Law (restrictive covenants on land are imposed upon subsequent purchasers if the covenant benefits neighbouring land)
- Agency and the assignment of contractual rights are permitted.
- Third-party insurance - A third party may claim under an insurance policy made for their benefit, even though that party did not pay the premiums.
- Contracts for the benefit of a group, where a contract to supply a service is made in one person's name but is intended to sue at common law if the contract is breached; there is no privity of contract between them and the supplier of the service.
Attempts have been made to evade the doctrine by implying trusts (with varying success), constructing the Law of Property Act 1925 s. 56(1) to read the words "other property" as including contractual rights, and applying the concept of restrictive covenants to property other than real property (without success).
- in case of trust/beneficiary
- in case of family arrangement
- in case of acknowledgment of debts
- in case of assignment of contract.
In England and Wales, the Contracts (Rights of Third Parties) Act 1999 provided some reform for this area of law which has been criticised by judges such as Lord Denning and academics as unfair in places. The act states:1. - (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.
This means that a person who is named in the contract as a person authorised to enforce the contract or a person receiving a benefit from the contract may enforce the contract unless it appears that the parties intended that he may not.
The Act enables the aim of the parties to be fully adhered to. In Beswick v Beswick, the agreement was that Peter Beswick assign his business to his nephew in consideration of the nephew employing him for the rest of his life and then paying a weekly annuity to Mrs. Beswick. Since the latter term was for the benefit of someone not party to the contract, the nephew did not believe it was enforceable and so did not perform it, making only one payment of the agreed weekly amount. Yet the only reason why Mr. Beswick contracted with his nephew was for the benefit of Mrs. Beswick. Under the Act, Mrs. Beswick would be able to enforce the performance of the contract in her own right. Therefore, the Act realises the intentions of the parties.
The law has been welcomed by many as a relief from the strictness of the doctrine, however it may still prove ineffective in professionally drafted documents, as the provisions of this statute may be expressly excluded by the draftsmen.
In Hong Kong, the Contracts (Rights of Third Parties) Ordinance provided for a similar legal effect as the Contracts (Rights of Third Parties) Act 1999.
In Australia, it has been held that third-party beneficiaries may uphold a promise made for its benefit in a contract of insurance to which it is not a party (Trident General Insurance Co Ltd v. McNiece Bros Pty Ltd (1988) 165 CLR 107). It is important to note that the decision in Trident had no clear ratio, and did not create a general exemption to the doctrine of privity in Australia.
Queensland, the Northern Territory and Western Australia have all enacted statutory provisions to enable third party beneficiaries to enforce contracts, and limited the ability of contracting parties to vary the contract after the third party has relied on it. In addition, section 48 of the Insurance Contracts Act 1984 (Cth) allows third-party beneficiaries to enforce contracts of insurance.
Although damages are the usual remedy for the breach of a contract for the benefit of a third party, if damages are inadequate, specific performance may be granted (Beswick v. Beswick  AC 59).
The issue of third-party beneficiaries has appeared in cases where a stevedore has claimed it is covered under the exclusion clauses in a bill of lading. In order for this to succeed, three factors must be made out:
- The bill of lading must clearly intend to benefit the third party.
- It is clear that when the carrier contracts with the consignor, it also contracts as an agent of the stevedore. That is, either the carrier must have had authority by the stevedore to act on its behalf, or the stevedore must later ratify (endorse) the actions of the carrier.
- Any difficulties with consideration moving from the stevedores must be made out.
The last issue was explored in New Zealand Shipping Co Ltd v. A M Satterthwaite & Co Ltd  AC 154, where it was held that the stevedores had provided consideration for the benefit of the exclusion clause by the discharge of goods from the ship.
New Zealand has enacted the Contracts Privity Act 1982, which enables third parties to sue if they are sufficiently identified as beneficiaries by the contract, and in the contract it is expressed or implied they should be able to enforce this benefit. An example case of not being "sufficiently identified" is that of Field v Fitton (1988).
