UBE Third-party Beneficiaries
Last updated: May 2, 2026
Third-party Beneficiaries questions are one of the highest-leverage areas to study for the UBE. This guide breaks down the rule, the elements you need to recognize, the named traps that catch most students, and a memory aid that scales to test day. Read it once, then practice the same sub-topic adaptively in the app.
The rule
A third party may enforce a contract only if she is an intended beneficiary — meaning the contracting parties intended to confer a direct benefit on her, as judged primarily by the terms of the contract and the surrounding circumstances. Restatement (Second) of Contracts § 302 distinguishes intended beneficiaries (creditor or donee) from incidental beneficiaries, who have no enforcement rights. Once the beneficiary's rights vest — by manifesting assent at the promisor's request, materially relying on the promise, or filing suit — the original parties can no longer modify or rescind without her consent (Restatement § 311).
Elements breakdown
Intended Beneficiary (General Test)
A non-party whom the contracting parties intended to benefit directly and who therefore has standing to enforce the contract.
- Recognition of right appropriate to effectuate intent of parties
- Performance satisfies promisee's obligation to beneficiary OR promisee intends to give beneficiary benefit of performance
- Circumstances indicate promisee intends to confer right of enforcement
Creditor Beneficiary
An intended beneficiary to whom the promisee owes (or believes she owes) a pre-existing duty that the promisor's performance will satisfy.
- Promisee owes pre-existing duty to beneficiary
- Promisor's performance will discharge or satisfy that duty
- Promisee's intent is to satisfy the obligation
Donee Beneficiary
An intended beneficiary to whom the promisee owes no obligation but intends to make a gift of the promisor's performance.
- No pre-existing duty owed by promisee to beneficiary
- Promisee's purpose is to confer a gift
- Performance directly benefits the third party
Incidental Beneficiary
A third party who happens to benefit from a contract but whom the parties did not intend to benefit, and who therefore cannot sue to enforce.
- Benefit to third party is unintended byproduct
- No manifestation of intent to confer enforcement right
- No standing to enforce against either party
Vesting of Beneficiary's Rights
The point after which the original promisor and promisee can no longer modify or discharge the beneficiary's rights without her consent.
- Beneficiary manifests assent at promisor's request, OR
- Beneficiary materially changes position in justifiable reliance, OR
- Beneficiary brings suit to enforce the promise
Beneficiary's Suit Against the Promisor
An intended beneficiary may sue the promisor directly to enforce the promised performance.
- Plaintiff is intended beneficiary
- Promisor breached duty of performance owed under contract
- Promisor may assert any defense good against promisee (e.g., failure of consideration, mistake, illegality)
Beneficiary's Suit Against the Promisee
A creditor beneficiary may sue the promisee on the underlying debt; a donee beneficiary generally cannot sue the promisee because no underlying obligation exists.
- Creditor beneficiary: may sue promisee on original obligation
- Donee beneficiary: no claim against promisee absent reliance
- Creditor beneficiary cannot recover twice (single satisfaction rule)
Common patterns and traps
The Promisee's-Intent Filter
The threshold issue is always whose intent controls. The Restatement and majority rule key off the promisee's intent because the promisee is the one who paid for or bargained for the promisor's performance. Distractors invite you to look at the promisor's expectations or the third party's hopes — both are irrelevant at the standing stage.
A choice that says 'Yes, because the third party reasonably expected to benefit' or 'No, because the promisor did not know about the third party' — both ignore that promisee's intent governs.
The Vesting Cutoff
Modification and rescission questions turn on whether vesting has occurred. Before vesting, the original parties may freely modify or discharge the beneficiary's rights; after vesting, they cannot without her consent. Watch for fact patterns where the beneficiary learns of the contract but takes no action — mere knowledge is not vesting.
A choice that says the beneficiary is bound by a later modification 'because she had not yet brought suit' — wrong if she had already materially relied or assented at promisor's request.
The Promisor's-Defenses Trap
When the beneficiary sues the promisor, the promisor may raise any defense she would have had against the promisee (failure of consideration, fraud, impracticability, etc.). Candidates often assume the beneficiary takes 'free and clear' because she is innocent. She doesn't — she steps into the promisee's shoes.
A choice that lets the beneficiary recover 'because she did nothing wrong,' ignoring that the underlying contract was voidable for the promisee's misrepresentation.
The Incidental-Benefit Mirage
Government contracts, public-works contracts, and contracts whose performance creates diffuse public benefits are classic incidental-beneficiary territory. Members of the general public are almost never intended beneficiaries unless the contract names a specific class and clearly contemplates enforcement by its members.
A choice allowing a member of the public to sue a contractor who promised the city to maintain street lights — incidental, not intended.
The Creditor-vs-Donee Misclassification
The distinction matters because a creditor beneficiary retains a parallel suit against the promisee on the underlying debt, while a donee beneficiary generally has no claim against the promisee. Distractors mix these up by giving a donee a route to sue the promisee, or by denying a creditor her parallel claim.
A choice that says 'the beneficiary may sue only the promisor' in a fact pattern where the promisee owed the beneficiary a pre-existing debt.
How it works
Start by mapping the contract: identify the promisor (the party who is to render performance to the third party), the promisee (the party who extracted that promise and to whom the promisor is contractually bound), and the third party. Then ask the only question that matters at the threshold: did the promisee intend to confer a direct benefit on the third party? If Reyes hires Liu Construction to repair the roof of Reyes's elderly mother, the mother is an intended (donee) beneficiary because the whole point of the deal was to benefit her. If, instead, Reyes hires Liu to repave Reyes's driveway, and the neighbor's property value rises as a result, the neighbor is merely incidental — no enforcement rights, full stop. Once you confirm intended-beneficiary status, check vesting: if the beneficiary has assented, relied, or sued, the original parties' attempt to rescind or modify is a nullity as to her. Finally, in any suit by the beneficiary against the promisor, the promisor keeps every defense she would have had against the promisee — the beneficiary stands in the promisee's shoes and takes the contract as it is.
Worked examples
Will Reyes Roofing prevail?
- A No, because Patel and Liu, as the original contracting parties, retained the right to modify the contract at any time before Reyes Roofing filed suit.
- B No, because Reyes Roofing was a donee beneficiary and donee beneficiaries cannot enforce the contract against the promisor.
- C Yes, because Reyes Roofing was an intended creditor beneficiary whose rights had vested before the modification. ✓ Correct
- D Yes, because Liu's promise to Patel created a unilateral contract that Reyes Roofing accepted by performance.
Why C is correct: Reyes Roofing is an intended creditor beneficiary: Patel (promisee) owed Reyes a pre-existing $18,000 debt, and Liu's promise to pay Reyes was intended to satisfy that obligation. Reyes Roofing's email manifesting assent and reliance vested its rights under Restatement § 311 before the modification. Once vested, Patel and Liu could not extinguish Reyes Roofing's rights without its consent.
Why each wrong choice fails:
- A: This states the rule for the period before vesting only. Reyes Roofing's email manifesting assent and reliance vested its rights, after which Patel and Liu lost the unilateral power to modify. (The Vesting Cutoff)
- B: This misclassifies the beneficiary. Reyes Roofing is a creditor beneficiary, not a donee — and in any event both donee and creditor intended beneficiaries can enforce against the promisor. (The Creditor-vs-Donee Misclassification)
- D: There is no separate unilateral contract. Reyes Roofing's right arises from its status as an intended beneficiary of the Patel-Liu bilateral contract, not from any independent acceptance.
Is Patel likely to prevail on her contract claim?
- A Yes, because the contract specifically referenced the safety of pedestrians, making Patel an intended beneficiary.
- B Yes, because any member of the public who uses a public road is an intended beneficiary of a municipal paving contract.
- C No, because Patel was at most an incidental beneficiary and lacks standing to enforce the contract. ✓ Correct
- D No, because tort, not contract, is the exclusive remedy for personal injuries arising from defective public works.
Why C is correct: Members of the general public are presumptively incidental beneficiaries of government contracts unless the contract clearly evidences an intent that individual members of the public have a right to enforce. A boilerplate reference to 'safety of motorists and pedestrians' is not enough to overcome the presumption. Patel therefore lacks standing under Restatement § 313.
Why each wrong choice fails:
- A: This overreads the contract language. General references to public safety in a government contract do not, without more, manifest the parties' intent to confer enforcement rights on individual members of the public. (The Incidental-Benefit Mirage)
- B: This is the categorical rule the Restatement rejects. Public-use beneficiaries of government contracts are presumptively incidental, not intended. (The Incidental-Benefit Mirage)
- D: This is an overstatement. Tort and contract claims can coexist; the contract claim fails here because of beneficiary status, not because tort displaces contract.
What is Liu's strongest defense?
- A Sofia is a donee beneficiary and donee beneficiaries cannot sue the promisor directly.
- B Sofia's rights had not vested because she did not manifest assent at Liu's request.
- C Liu may assert against Sofia any defense Liu would have against Reyes, including Reyes's fraudulent misrepresentation, which renders the contract voidable. ✓ Correct
- D Sofia's reliance on a gift promise is barred by the Statute of Frauds.
Why C is correct: Although Sofia is an intended donee beneficiary whose rights vested through material reliance, she takes the contract subject to all defenses Liu would have against the promisee, Reyes. Reyes's fraudulent misrepresentation makes the contract voidable at Liu's option, and Liu may assert that defense against Sofia. The beneficiary stands in the promisee's shoes and inherits the contract's infirmities.
Why each wrong choice fails:
- A: Donee beneficiaries can sue the promisor; that is the principal route by which donee beneficiaries enforce gift promises. The category does not bar suit against the promisor. (The Creditor-vs-Donee Misclassification)
- B: Vesting is not limited to assent at the promisor's request — material reliance and filing suit also vest rights. Sofia's $4,000 non-refundable deposit is material reliance, so her rights had vested. (The Vesting Cutoff)
- D: The Statute of Frauds does not bar enforcement here; the underlying contract is the sale of a motorcycle (goods over $500, but presumably written), and Sofia's reliance is not a separate gift promise requiring its own writing.
Memory aid
VEST: Vesting requires Voluntary assent, Express reliance, or Suit/litiigation Triggered by the beneficiary. For type, ask: 'Was the promisee paying off a Debt or making a Gift?' Debt = creditor; Gift = donee; Neither = incidental.
Key distinction
Intended versus incidental is determined by the promisee's intent, not the promisor's intent and not the third party's expectations — the controlling question is whether the promisee bargained for the promisor's performance to flow to the third party.
Summary
An intended beneficiary — creditor or donee — can sue the promisor to enforce the contract once her rights have vested, but an incidental beneficiary takes nothing.
