Understanding Promissory Estoppel: What You Need to Know

What is promissory estoppel? It’s a legal rule that can affect contracts, especially when promises are involved. But what does it mean, and how does it work, especially in situations like franchise agreements? Let’s break it down.

Defining Promissory Estoppel

Promissory estoppel is a legal idea that stops someone from breaking a promise if another person relied on it and got hurt because of that reliance.

Key Elements: To better answer the question of what is promissory estoppel, think about these three things:

  1. Promise: It starts with a clear promise made by one person to another.
  2. Reasonable Reliance: The person who heard the promise has to have believed it and acted on it in a sensible way.
  3. Detrimental Change: Because of their belief in the promise, they end up in a worse position than before.

Implications and Applications

Promissory estoppel matters a lot in contracts, even in franchise deals. Lets look at a practical example. Imagine a franchisor tells a franchisee they can renew their contract when it ends, and promises a renewal franchise agreement will be provided. Based on this, the franchisee spends a lot of money improving their business. But when the time comes, the franchisor changes their mind and refuses to renew.

In this case, promissory estoppel can help the franchisee. If they can show they relied on the promise and suffered because of it, a court might force the franchisor to keep their word or give compensation. This is the case even if the renewal franchise agreement was never provided or signed. Promissory estoppel is about making sure people keep their promises, especially when others rely on them. It helps keep contracts fair and makes sure everyone sticks to their word.


Promissory estoppel is a big deal in contracts, including franchises. It’s all about fairness and keeping promises, which is important in any business deal. So, when you hear about it next time, remember it’s about making sure people do what they said they would.
