Illusory Promises: When a Promise Is Not Really a Promise

What Is an Illusory Promise?

An illusory promise is a statement that appears to commit a party to something but actually leaves them free to perform or not perform at their sole discretion. Because a valid contract requires mutual consideration — each party must give up something of value — an illusory promise may fail to create a binding obligation.

Examples of Illusory Promises

  • "I will buy your product if I feel like it"
  • "We will provide services at our sole discretion"
  • "The company reserves the right to change or cancel this program at any time for any reason"
  • A requirements contract where the buyer has no actual obligation to have any requirements

Why It Matters

If one party's promise is illusory, there may be no consideration on their side, which means no enforceable contract exists. The other party could walk away without liability — but so could the party who made the illusory promise.

How Courts Handle It

Courts generally try to find ways to uphold contracts rather than strike them down. Common approaches include:

  • Implying good faith obligations — even if the contract says "at our discretion," courts may read in a duty of good faith and fair dealing
  • Finding partial commitment — if the promise includes any limitation on the promisor's discretion, it may not be truly illusory
  • Looking at the full agreement — other provisions may supply the missing consideration

Red Flags in Your Contract

  • Termination clauses allowing one party to cancel for any reason with zero notice
  • Unlimited discretion to modify key terms (price, scope, duration)
  • Phrases like "at our sole and absolute discretion" on core obligations
  • Satisfaction clauses without an objective or good faith standard

When to Consult a Lawyer

Consider seeking legal advice if your contract contains terms that give the other party unlimited discretion over their core obligations, as this could affect enforceability.
