Third Party Beneficiaries in Contract Law

Jul 18, 2025

Overview

This lecture explains the legal concept of third party beneficiaries in contract law, outlining their rights, types, and the circumstances under which they can enforce a contract.

Third Party Beneficiaries in Contract Law

  • A third party beneficiary is someone who benefits from a contract but is not a direct party to it.
  • American courts have recognized third party beneficiary rights since at least 1806 (Lawrence v. Fox).
  • Third party beneficiaries may have legal standing to enforce a contract if they are intended beneficiaries.

Types of Third Party Beneficiaries

  • Donee beneficiary: Receives a benefit from a contract as a gift, not as compensation for service.
  • Creditor beneficiary: Receives a benefit because the promisee owes them a legal obligation (debt repayment).

Identifying Intended Beneficiaries

  • An intended beneficiary is typically named or specifically identified in the contract.
  • The beneficiary receives performance directly or the contract circumstances show the benefit is for them.
  • Life insurance policy beneficiaries are classic intended beneficiaries.

Enforcing Contract Rights

  • Both donee and creditor intended beneficiaries can enforce contract rights.
  • A third party's rights must "vest" before they can enforce the contract.
  • Vesting occurs when: (1) the beneficiary assents as requested, (2) the beneficiary sues to enforce, or (3) the beneficiary materially changes position in reliance on the contract.
  • Before rights vest, the original parties can modify the contract; after vesting, changes require the beneficiary's consent.

Case Examples

  • Lawrence v. Fox: Recognized intended beneficiary rights in a debt repayment scenario.
  • Snow shoveling example: Elderly neighbor Bob as a gratuitous donee beneficiary.
  • Logan Baldwin v. LSM: Homeowners as intended third party beneficiaries due to contract circumstances.
  • Adam, Bertha, and Carla: Carla’s rights vested after she assented via email.
  • Sandy, Joan, and Jayne: Jayne's rights vested after she relied on the promise and changed her position.

Key Terms & Definitions

  • Third party beneficiary — someone who is not a party to a contract but stands to benefit from its performance.
  • Donee beneficiary — a person receiving a contract benefit as a gift, not repayment.
  • Creditor beneficiary — a person who is owed a debt and benefits from a contract made to satisfy that debt.
  • Intended beneficiary — a third party clearly identified and meant to benefit from a contract.
  • Vesting — the moment when a beneficiary’s rights to enforce a contract become legally enforceable.

Action Items / Next Steps

  • Review contract law cases involving third party beneficiaries.
  • Prepare examples distinguishing donee and creditor beneficiaries for discussion.
  • Read about vesting and its impact on modifying contractual rights.
