Understanding the Preexisting Duty Rule in Contract Law

Definition & Meaning

The preexisting duty rule is a principle in contract law that states a party cannot offer something they are already obligated to do as consideration for a new promise. In simpler terms, if someone is already required to perform a task under an existing contract, their promise to do that task cannot be used as a basis for modifying the contract or for making a new agreement. This rule ensures that both parties provide new consideration when altering a contract.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A builder has a contract to construct a house for a set price. If the builder later demands an additional payment to complete the project, the homeowner's agreement to pay more is not enforceable because the builder is already obligated to finish the job.

Example 2: A contractor is hired to provide landscaping services. If the contractor requests extra payment to perform tasks that are already included in the original contract, the request for additional payment would not be valid under the preexisting duty rule. (hypothetical example)
