Право третьего лица по договору: понятие и применение.

A third party beneficiary, in the law of contracts, is a person who may have the right to sue on a contract, despite not having originally been an active party to the contract. This right, known as a ius quaesitum tertio, arises when the third party (tertius or alteri) is the intended beneficiary of the contract, as opposed to a mere incidental beneficiary (penitus extraneus). It vests when the third party relies on or assents to the relationship, and gives the third party the right to sue either the promisor (promittens, or performing party) or the promisee (stipulans, or anchor party) of the contract, depending on the circumstances under which the relationship was created. A contract made in favor of a third party is known as a "third party beneficiary contract." Under traditional common law, the ius quaesitum tertio principle was not recognized, instead relying on the doctrine of privity of contract, which restricts rights, obligations, and liabilities arising from a contract to the contracting parties (said to be privy to the contract). However, the Contracts (Rights of Third Parties) Act 1999 introduced a number of allowances and exceptions for ius quaesitum tertio in English law. Other common law countries are also making reforms in this area, though the United States is unique in abandoning privity early in the mid 19th century.

A third party beneficiary only acquires a right of action to enforce his benefit once he has accepted the benefit provided for in the contract. Under the South African interpretation, however, prior to formal acceptance of the benefit, the third party beneficiary only has a spes, or expectation; in other words, he does not have the right to accept, but rather a mere competency. Acceptance may also be a suspensive condition in certain contracts. Under Scots law, acceptance is not necessary to be vested in a right of action, but is necessary to be liable. Before acceptance, however, the ius quaesitum tertio is tenuous so that acceptance of a benefit does not create a right, but rather entrenches that right. In either case, the contracting parties may vary or rescind the contract until acceptance or reliance.

In order for a third party beneficiary to have any rights under the contract, he must be an intended beneficiary, as opposed to an incidental beneficiary. The burden is on the third party to plead and prove that he was indeed an intended beneficiary.

An incidental beneficiary is a party who stands to benefit from the execution of the contract, although that was not the intent of either contracting party. For example, if Andrew hires Bethany to renovate his house and insists that she use a specific house painter, Charlie, because he has an excellent reputation, then Charlie is an incidental beneficiary. Neither Andrew nor Bethany is entering into the contract with the particular intent to benefit Charlie. Andrew simply wants his house properly renovated; Bethany simply wants to be paid to do the renovation. If the contract is breached by either party in a way that results in Charlie never being hired for the job, Charlie nonetheless has no rights to recover anything under the contract. Similarly, if Andrew were to promise to buy Bethany a Cadillac, and were to later go back on that promise, General Motors would have no grounds upon which to recover for the lost sale.

Where a contract for the benefit of a third party is breached by the non performance of the promisor, the beneficiary can sue the promisor for the breach just as any party to a contract can sue the other. Because the rights of the third party are defined by the contract created between the promisor and the promisee, the promisor may assert against the beneficiary any defenses to the contract that could be asserted against the promisee. These include all of the traditional basis by which the formation of a contract may be challenged (e. g., lack of capacity, lack of consideration, the statute of frauds) and all of the traditional bases by which non performance on the contract may be excused (e. g., failure of consideration, impossibility, illegality, frustration of purpose). Because the promisor can assert any defenses that could be asserted against the promisee, the beneficiary also becomes liable for counterclaims on the contract that the promisor could establish against the promisee. This liability can never exceed the amount that the promisor owes under the contract. In other words, if the promisor is owed money by the promisee, any award to the third party for the promisor's failure to perform can be reduced by the amount thus owed. If the promisor is owed more than the value of the contract, the beneficiary's recovery will be reduced to nothing (but the third party can never be made to assume an actual debt). A creditor beneficiary can sue both the promisor and the promisee, but the beneficiary cannot recover against both. If the suit is successful against one party to the contract, the other party will be dismissed. Because the creditor beneficiary is receiving the performance of the promisor in order to fulfill the promisee's debt, the failure of the promisor to perform means that the beneficiary can still sue the promisee to recover the preexisting debt. The failure of performance simply means that the debt has never been paid. A donee beneficiary can sue the promisor directly to enforce the promise. (Seaver v. Ransom, 224 NY 233, 120 NE 639 [1918]). A donee beneficiary is when a contract is made expressly for giving a gift to a third party, the third party is known as the donee beneficiary. The most common donee beneficiary contract is a life insurance policy. In the United States, the Restatement (Second) of Contracts, Chapter 6, Sections 133 147, covers third party beneficiaries.

The promisee can also sue the promisor for failing to pay the third party beneficiary. Under the common law, such suits were barred, but courts have since determined that the promisee can sue for specific performance of the contract, provided that the beneficiary has not already sued the promisor. Furthermore, if the promisee was in debt to a creditor beneficiary, and the failure of the promisor to perform caused the promisee to be held liable for that debt, the promisee can sue to recover the amount of the debt.

Lawrence v. Fox, 1859, decided in the New York Court of Appeals allows a third party to sue for debt collection.
