18.1 Third-Party Beneficiaries

18.1 Third-Party Beneficiaries

Third-party beneficiary questions ask whether a person who did not sign a contract may enforce it. Answer three questions in order: Is the plaintiff an intended beneficiary? Have the beneficiary's rights vested so that the contracting parties could no longer change them? And what defenses may the promisor raise?

Third-Party Beneficiaries (3PB)

A third-party beneficiary contract is formed when two parties (the promisor and the promisee) enter into an agreement with the intention of conferring a direct benefit upon a non-party (the third-party beneficiary).

A. Intended vs. Incidental Beneficiaries

• Intended Beneficiary: A third party whom the contracting parties expressly intended to benefit directly from performance. An intended beneficiary has legal standing to enforce the contract.
  • Indicators of Intent: Contract explicitly names the third party; performance runs directly from promisor to third party; or a close relationship exists demonstrating the promisee intended to benefit the third party.
• Incidental Beneficiary: A third party who benefits tangentially or peripherally from performance, but for whom no direct benefit was intended. An incidental beneficiary has NO legal standing or rights to enforce the contract.
  • Example: A city contracts with a general contractor to build a multi-million-dollar public park. An adjacent retail store owner whose property value will increase significantly is an incidental beneficiary and cannot sue if the contractor defaults.

B. Creditor Beneficiary vs. Donee Beneficiary

The first Restatement of Contracts classified intended beneficiaries into two categories, and many courts and exam questions still use these labels. The Restatement (Second) § 302 abandons the labels and asks whether recognizing a right in the beneficiary is appropriate to carry out the parties' intention and either (a) performance will satisfy the promisee's obligation to pay money to the beneficiary or (b) the circumstances indicate that the promisee intends to give the beneficiary the benefit of the promised performance. The traditional categories are:

1. Creditor Beneficiary: The promisee's primary purpose in obtaining the promisor's commitment is to satisfy an actual, asserted, or preexisting legal debt or obligation owed by the promisee to the third party.
   • Rights upon Breach: A creditor beneficiary can sue BOTH the promisor (on the contract) AND the promisee (on the underlying preexisting debt), but is entitled to only one full satisfaction.
2. Donee Beneficiary: The promisee's primary purpose is to confer a gift or gratuitous benefit upon the third party.
   • Rights upon Breach: A donee beneficiary can sue the promisor directly on the contract, but CANNOT sue the promisee, because the promisee's commitment was a gratuitous gift unsupported by consideration (unless detrimental reliance triggers promissory estoppel).

C. Vesting of Third-Party Rights

The promisor and promisee retain the legal power to modify, amend, or rescind their contract without the third party's consent until the beneficiary's rights VEST.

The Three Vesting Events (Restatement (Second) § 311):

A third-party beneficiary's rights vest the moment ANY ONE of the following three events occurs:

1. The beneficiary manifests assent to the contract promise in a manner requested by the parties;
2. The beneficiary brings a legal action to enforce the promise; OR
3. The beneficiary materially changes position in justifiable reliance on the promise.

└────────────────────────────────────────┴────────────────────────────────────────┘

D. Defenses Against the Third-Party Beneficiary

When an intended beneficiary sues the promisor, the beneficiary's rights derive entirely from the underlying contract.

• Universal Rule: The promisor may assert against the third-party beneficiary any defense arising out of the contract that the promisor could have asserted against the promisee.
• Recognized Defenses: Lack of mutual assent, failure of consideration, Statute of Frauds, mutual mistake, fraud in the inducement, failure of an express condition precedent, or material breach by the promisee.
• Limitation: The promisor cannot assert independent personal counterclaims or set-offs against the beneficiary that arise from separate transactions with the promisee, unless the contract expressly provides otherwise.

Applying Third-Party Beneficiary Rules

Intended or Incidental? Common Examples

Vesting Details

• Reserved powers: If the contract reserves the power to change the beneficiary—as nearly all life insurance policies do—the parties may change or cancel the beneficiary's rights despite reliance or assent, following the contract's procedure (Restatement § 311(1)).
• Before vesting: Until a vesting event occurs, the promisor and promisee may modify or rescind the contract without the beneficiary's consent, even if the beneficiary knows of the contract.
• Notice: A beneficiary's reliance or suit counts only if it occurs before the beneficiary receives notice of the modification or discharge.

Rights of the Promisee

• The promisee may also sue the promisor for breach. A promisee of a donee beneficiary often obtains specific performance because damages would be inadequate, and a promisee whose debt to a creditor beneficiary goes unpaid may recover what it must pay the creditor (Restatement §§ 305, 307).
• The promisor's promise to the promisee does not release the promisee from its own debt to a creditor beneficiary unless the creditor agrees to a novation.

Defenses

• Contract defenses: The promisor may assert against the beneficiary any defense that makes the contract unenforceable or that arises from the promisee's own failure to perform, because the beneficiary's rights depend on the contract (Restatement § 309).
• Beneficiary's own conduct: The beneficiary's right is also subject to claims or defenses arising from the beneficiary's own conduct or agreements.
• Unrelated claims: The promisor may not set off claims it has against the promisee from unrelated transactions, unless the contract provides otherwise.
