You think you have a deal. You shook hands, signed a piece of paper, and maybe even toasted to the future. But then things go south. You head to a lawyer, and they ask you one question that makes your stomach drop: "What was the consideration?"
If you're staring blankly, you aren't alone.
Honestly, most people think a contract is just an agreement. It isn't. In the eyes of the law, a contract is a bargain. To understand what does consideration mean, you have to stop thinking about promises and start thinking about "the price of the promise." It’s the "this for that." Without it, you don't have a contract; you just have a gift or a pinky swear that the courts won't touch.
The Basic Guts of Legal Consideration
Basically, consideration is something of value exchanged by the parties to a contract. It’s the fuel in the engine. If I promise to give you my vintage 1968 Mustang for free because I like your face, and then I change my mind, you can't sue me. Why? Because you didn't give me anything in return. There was no consideration.
But if you give me one dollar? Just one? Suddenly, the law perks up.
Legally, the value doesn't have to be "fair." The courts generally don't care if you made a bad deal. They care if there was a deal. This is often called the "peppercorn rule." Back in the day, English courts decided that even a single peppercorn was sufficient consideration to make a contract binding. It’s about the exchange, not the market value.
There are two main ways this looks in the real world:
- A benefit to the person promising something (the promisor).
- A detriment to the person receiving the promise (the promisee).
That "detriment" part is where things get interesting. You don't necessarily have to hand over cash. You just have to give up something you had a legal right to keep.
The Case That Changed Everything: Hamer v. Sidway
To really get what does consideration mean, we have to look at a classic case from 1891. It involves a nephew, an uncle, and a lot of vice.
The uncle, William E. Story I, promised his nephew $5,000 (which was a massive fortune back then) if the kid would stop drinking, using tobacco, and playing cards or billiards for money until he turned 21. The nephew agreed. He stayed "clean" for years. When he turned 21, he wrote to his uncle, who acknowledged the debt but died before paying it.

The estate refused to pay. They argued there was no consideration because the nephew actually benefited from staying sober. They said he didn't lose anything; he gained health!
The New York Court of Appeals disagreed. They ruled that because the nephew had the legal right to drink and gamble, giving up those rights constituted a legal detriment. That was the consideration. It didn't matter if it helped his liver; it mattered that he restricted his lawful freedom. That’s a contract.
When Consideration Fails (and Why Your Boss Might Be Lying)
Sometimes people think they have consideration when they really have a big pile of nothing. This is where "past consideration" comes in.
Imagine you’ve worked at a tech firm for five years. You’ve been a rockstar. Your boss pulls you into the office and says, "Because you’ve been so great over the last five years, I’m going to give you a $50,000 bonus next month."
You're thrilled. You go out and put a down payment on a boat.
Then, the bonus never arrives. Can you sue? Probably not.
The work you did over the last five years is "past consideration." You already did it. You didn't do it in exchange for the promise of the bonus; you did it for your salary at the time. Since the bonus was promised for something you already finished, it’s considered a "nudum pactum"—a naked promise. It’s not enforceable because there’s no new exchange happening.
The Pre-Existing Duty Rule
This is another trap. It happens in construction all the time.
Suppose a contractor agrees to build you a deck for $10,000. Halfway through, they stop and say, "Actually, lumber is more expensive than I thought. I’m not finishing unless you pay me an extra $2,000." You're desperate, so you agree.

When the deck is done, you pay them the original $10,000 and tell them to kick rocks regarding the extra $2,000.
If they sue you, they will lose. They were already under a "pre-existing duty" to build that deck for $10,000. Doing what you are already legally obligated to do is not new consideration. You got nothing extra for your $2,000 promise, so the promise isn't binding.
The Exception: When Fairness Overrules Logic
Law isn't always cold and clinical. There’s a concept called Promissory Estoppel.
Sometimes, one person makes a promise knowing the other person will rely on it. If that person then spends money or changes their life based on that promise, a judge might step in to prevent "injustice," even if there’s no formal consideration.
It’s the "safety net" of the legal world.
If a charity promises to name a building after you if you pledge a million dollars, and they start construction based on your word, you might be on the hook. Even though you haven't "received" the building yet, the charity's reliance on your promise creates a legal obligation. It’s messy. It’s complicated. But it’s how the system tries to stay human.
Why Business Owners Get This Wrong
In the world of startups and "handshake deals," consideration is often the first thing to break.
Think about "illusory promises." This is when someone says, "I'll buy as much of your product as I want to." That sounds like a deal, right? Wrong. Since they have the option to want zero product, they haven't actually committed to anything. There is no "mutuality of obligation."
If you’re drafting an agreement, you need to ensure both sides are actually bound to do something.

Real-World Nuance: Moral Consideration
Can "love and affection" be consideration?
In most states, the answer is a flat "no." If your dad promises to give you his house because he loves you, that’s a gift. If he signs a deed, it’s yours. But if he just says it, and you don't give him anything in return, you can't force him to do it later. Love is great for relationships, but it’s terrible for contracts.
How to Protect Yourself
Understanding what does consideration mean isn't just for bar exams. It's for anyone signing a lease, taking a job, or selling a car.
If you are entering an agreement, you must identify what you are giving and what you are getting. If you are the one receiving a promise, make sure you are providing something—even something small—in exchange.
For example, when employees leave a company and sign a "non-compete" or "non-disparagement" agreement, the company usually pays them a small severance or even just a nominal fee like $500. Why? Because the employee is giving up their right to work elsewhere or speak their mind. The $500 is the consideration that makes that restriction legal. Without that payment, many of those "exit papers" aren't worth the ink they're printed with.
Key Takeaways for Practical Use
Don't let the legal jargon intimidate you. Consideration is basically the "Why" of a contract.
- Check for "The Exchange": If only one person is doing something, it’s a gift. Gifts are revocable.
- Past is Past: You cannot use work you’ve already completed as consideration for a new promise today.
- The Amount Doesn't Matter: A dollar, a used bike, or a promise to stop smoking is enough. The law doesn't protect you from a bad bargain, only a non-existent one.
- Get it in Writing, But Don't Stop There: Even a written contract is invalid if it lacks consideration.
Next time you're about to enter an agreement, ask yourself: "What am I giving up that I don't have to give up?" If the answer is "nothing," you don't have a contract. You have a conversation.
Moving Toward a Valid Agreement
To ensure your next agreement holds up in court or just in a basic business dispute, take these specific steps immediately:
- Identify the "New" Value: Explicitly state in the document what each party is providing. Avoid vague phrases like "for good and valuable consideration." Be specific. "In exchange for $100 and the delivery of the software..."
- Verify Mutuality: Ensure that both parties are restricted in some way. If one party can walk away at any time for any reason without penalty, the consideration might be "illusory."
- Address Modifications Separately: If you are changing an existing contract (like a construction job or a service agreement), ensure you are providing something new in exchange for the change. If the price goes up, the scope of work should ideally change too.
- Consult an Expert on Nuance: If you are relying on a promise that involves a lot of money, especially in "reliance" situations where no clear exchange exists, speak to a contract attorney about Promissory Estoppel.
Understanding these mechanics turns a "handshake" into a "stronghold." It keeps your business interests safe and your expectations grounded in reality.
