In a contract, the phrase “in consideration of” introduces the exchange that makes the agreement enforceable. It names what one side is giving in return for what the other side is giving — the money, the work, the promise, the property, or the right being surrendered. Without that exchange, called consideration, a court will usually treat the document as a statement of intent rather than a binding contract.
Where You See the Phrase and What It Signals
The phrase typically sits near the top of a contract, just before the operative terms. A service agreement might read, “In consideration of the performance of the services described in Exhibit A, Client agrees to pay Service Provider the fees set forth in Exhibit B.” A purchase contract might say, “In consideration of the payment of the purchase price of $500,000 by Buyer to Seller, Seller agrees to convey the property to Buyer.” The wording shifts from deal to deal, but the function is the same: it identifies the bargain.
You will also see a broader form of the clause, something like “in consideration of the mutual covenants and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged.” This boilerplate acts as a safety net. When a contract recites that consideration has been received and is sufficient, it is harder for either party to argue later that the agreement lacked a real exchange.
What Consideration Actually Means
Consideration is the price each party pays for the other’s promise. Under the bargain theory used by most courts today, a promise counts as consideration when the person making the promise seeks it in exchange for what they are offering, and the person receiving the promise gives it in exchange for that offer. The Restatement (Second) of Contracts captures this in Section 71. The key word is “exchange.” Both sides must be trading.
An older formulation defines consideration as either a benefit to the person making the promise or a detriment to the person receiving it. In practice, the bargain theory and the benefit-detriment test usually reach the same result. The law enforces deals where both parties have something at stake. A one-sided transfer, like a gift, generally does not create a binding obligation.
Valid Forms of Consideration
Consideration does not have to be cash. Courts recognize several kinds of exchanges as legally sufficient.
- Money. Paying $500 for a piece of equipment is the clearest example.
- Services or labor. An accountant who files tax returns in exchange for a fee is providing a performance the law treats as valuable.
- Property. Transferring ownership of goods, real estate, or intellectual property all qualify.
- A return promise. Promising to deliver materials next month counts as consideration for the other party’s promise to pay.
- Forbearance. Agreeing not to do something you have a legal right to do. Giving up the right to sue after an accident is one of the most common examples, and it forms the backbone of nearly every settlement agreement.
Forbearance was the point of Hamer v. Sidway, in which an uncle promised his nephew $5,000 if the nephew refrained from drinking, smoking, swearing, and gambling until he turned 21. The court held that the nephew’s self-restraint was valid consideration because he gave up legal freedoms he otherwise had the right to exercise, even though the uncle gained nothing tangible.1NYCourts.gov.

Sufficient vs. Adequate
Courts draw a sharp line between two ideas that sound similar. Sufficiency asks whether the exchange has any legal value at all. Adequacy asks whether the exchange is economically fair.
On sufficiency, the bar is deliberately low. The old “peppercorn rule” holds that even something as trivial as a single peppercorn can be enough to make a contract binding, as long as both parties agreed to the trade. Courts look for the existence of an exchange, not its market value.
On adequacy, courts almost always stay out of it. If someone chooses to sell a luxury car for $1,000, a judge will not void the deal because the price looks too low. Competent adults set their own terms, even bad ones.
There is a limit. When the gap between what the parties exchange is so extreme that it shocks the conscience, especially when paired with unequal bargaining power, deception, or high-pressure tactics, a court may refuse to enforce the contract on grounds of unconscionability. The Restatement (Second) of Contracts, Section 208, recognizes that inadequacy of consideration alone does not void a bargain, but a gross disparity in the values exchanged can be a significant factor in finding a contract unconscionable.
Nominal Consideration
In some transactions, the stated consideration is a token amount, often “$1” or “$10 and other good and valuable consideration.” This appears often in real estate deeds, where family members transfer property without disclosing the true price. A parent who deeds a house to an adult child “for $10 and other valuable consideration” is using nominal consideration to satisfy the exchange requirement while keeping the real terms private. Courts generally accept nominal consideration, though if other issues like fraud or undue influence come up later, a court may look more closely at the transaction.
When “Consideration” Fails
Not every promise or action qualifies as consideration. Several common situations fail the test, leaving the resulting agreement unenforceable.
Past Consideration
If someone performs a service voluntarily and the other person later promises to pay for it, that promise usually cannot be enforced. The timing is wrong: the act was already finished before the promise was made, so the promise did not induce the performance. A neighbor who mows your lawn uninvited, and then hears you promise $50 for the work, holds a promise most courts will not enforce.
There is a narrow exception. Under the “material benefit rule,” reflected in Restatement (Second) Section 86, a promise made in recognition of a benefit already received can be enforceable if needed to prevent injustice, but only when the benefit was not intended as a gift and the promised amount is not wildly out of proportion to the benefit.
The Pre-Existing Duty Rule
You cannot use something you are already legally required to do as consideration for a new promise. A contractor already under contract to finish a building by June 1 cannot demand an extra $5,000 to meet that same deadline. The contractor already owed the performance, so there is no new exchange to support the extra payment.
This rule matters most for contract modifications. Under traditional common law, changing an existing contract requires fresh consideration from both sides. The Uniform Commercial Code carves out an important exception for sales of goods: under UCC Section 2-209, a modification to a sale-of-goods contract does not need new consideration to be binding, as long as both parties agree in good faith.2Legal Information Institute. UCC 2-209 – Modification, Rescission and Waiver A buyer and seller adjusting a delivery schedule or price under that provision can make the change stick without either side offering anything new.
Gift Promises
A promise to give someone something for free is not a contract, no matter how clearly it is stated. If your aunt promises you her car as a birthday gift and then changes her mind, you generally have no legal claim. No exchange, no consideration. The result can shift only if detrimental reliance comes into play, discussed below.
Illusory Promises
A promise that sounds like a commitment but actually leaves one side free to do whatever they want is called illusory. A seller who agrees to sell “as much ice cream as he wants to” has not really committed to anything, because he could sell zero and still comply. Only one side is bound, so there is no mutuality, and the agreement fails for lack of consideration.
Illusory promises show up often in employment and business contracts. A clause giving one party the unrestricted right to change the terms at any time, or to cancel at will with no notice, can make that party’s promise meaningless. When courts find a promise is illusory, they treat the agreement, or at least the illusory part, as unenforceable.
When a Promise Is Enforced Without Consideration
Promissory estoppel is the main exception to the consideration requirement. When someone makes a promise they should reasonably expect will cause the other person to act, and that person acts on the promise to their own detriment, a court can enforce the promise even though no traditional exchange took place.
The doctrine, set out in Restatement (Second) Section 90, has three elements:
- A clear promise the promisor should have expected would lead the other person to act or hold back from acting.
- Actual reliance by the promisee that caused real loss or gave up a real opportunity.
- Injustice if the promise is not enforced.
In Ricketts v. Scothorn, a grandfather gave his granddaughter a promissory note for $2,000 and told her she would not have to work anymore. She quit her job in reliance on the promise. After he died, his estate refused to pay. The Nebraska Supreme Court enforced the note because the grandfather had induced her to change her position, and letting the estate escape would have been unjust.
Promissory estoppel does not always give you the full benefit of a normal contract. Courts can limit the remedy to whatever is needed to avoid injustice, which sometimes means covering only the losses caused by the reliance rather than the full value of what was promised.
