How To Prove A California Promissory Estoppel Claim

 

In California, a claim of Promissory Estoppel is defined as:

This is an estoppel that prevents a promisor from denying the existence of a promise when the promisee reasonably and foreseeably relies on the promise and to his or her loss acts or fails to act and suffers an injustice that can only be avoided by enforcement of the promise

It simply means:

A promise may be enforced if it was clearly made and the other party relied on it to their detriment.

There are 4 elements of the claim:

  • Element 1. A party made a promise that was clear and unambiguous in its terms. A party clearly and unmistakably promised something specific, leaving no room for doubt about what they intended to do.

    Facts that might support this element look like:

    * The party explicitly stated in writing that they would provide financial support for the project if certain conditions were met.
    * During a meeting, the party verbally assured the other party that they would deliver the promised goods by a specific date.
    * The terms of the promise were documented in an email, outlining the exact amount and timeline for delivery.
    * The party provided a detailed proposal that included a clear commitment to perform specific actions in exchange for consideration.
    * The promise was made in the presence of witnesses who can attest to the clarity and certainty of the terms discussed.

  • Element 2. The party to whom the promise was made relied on it. This means that the person who received the promise took action or made decisions based on believing that the promise would be kept, showing they trusted the promise enough to rely on it for their choices.

    Facts that might support this element look like:

    * The plaintiff made significant financial investments based on the defendant’s promise, believing it would lead to a successful partnership.
    * The plaintiff turned down other business opportunities after receiving assurances from the defendant regarding their commitment.
    * The plaintiff incurred expenses for materials and labor in preparation for a project that was contingent on the defendant’s promise.
    * The plaintiff communicated their reliance on the defendant’s promise in multiple emails, expressing their expectation of fulfillment.
    * The plaintiff began hiring staff and securing contracts, all predicated on the defendant’s assurance of support.

  • Element 3. The reliance was both reasonable and foreseeable. In a promissory estoppel claim, “the reliance was both reasonable and foreseeable” means that the person who relied on a promise had a good reason to believe it would be kept, and it was expected that they would act based on that promise.

    Facts that might support this element look like:

    * The plaintiff had a long-standing business relationship with the defendant, which established a pattern of trust and reliance on the defendant’s promises.
    * The defendant explicitly stated that they would provide funding for the plaintiff’s project, leading the plaintiff to make significant financial commitments based on that promise.
    * The plaintiff communicated their reliance on the defendant’s promise in writing, detailing the steps they would take based on the expected support.
    * The defendant was aware that the plaintiff would incur expenses and make decisions based on the promised funding, making the reliance foreseeable.
    * The plaintiff had no reasonable alternative but to rely on the defendant’s promise, given the urgency of the project and the timeline involved.

  • Element 4. The party relying on the promise was injured by that reliance. This means that the person who trusted the promise suffered some harm or loss because they acted based on that promise, believing it would be fulfilled.

    Facts that might support this element look like:

    * The party relied on the promise by making a significant financial investment based on the assurance provided.
    * After receiving the promise, the party declined other opportunities, believing the commitment would be fulfilled.
    * The party incurred expenses related to preparations that were unnecessary due to the unfulfilled promise.
    * The party experienced a loss of business reputation after the promise was not honored, affecting future opportunities.
    * The party’s reliance on the promise led to emotional distress due to the unexpected outcome.
