A revocable contract is one that a party still has the legal power to take back. In practice, the term usually points to the offer stage: under common law, every offer is presumed revocable until the other side accepts it or something specific makes it binding. Once a contract is signed, the ability to walk away narrows sharply and depends on what the contract says and what the law allows. The rules that decide whether you can pull out, or whether the other side can, are what the rest of this article covers.
The Default Rule for Offers
The baseline in American contract law is simple. An offeror can withdraw an offer at any time before the offeree accepts. The offeror controls the terms, the timing, and the method of acceptance. Even a statement like “you have until Friday to decide” is not binding unless the offeree gave something of value to keep the offer open. A bare promise to hold an offer open is, legally, a promise you can break.
Offers also expire on their own. If the offer sets a deadline, it lapses when that deadline passes. If no deadline is stated, it expires after a reasonable time, which courts judge in context: an offer for a volatile commodity might last hours, while an offer to sell real estate might survive weeks. An offer also terminates automatically if the offeror dies or becomes legally incapacitated before acceptance. And if the offeree responds with a counteroffer instead of a clean acceptance, the original offer dies on the spot.1H2O. Restatement Second of Contracts Section 39 – Counter-offers
When an Offer Becomes Irrevocable
Four mechanisms strip the offeror’s power to withdraw. They arise in different situations and protect different interests, and knowing which one applies to your deal tells you whether the offer in front of you is really locked in.
Option Contracts
An option contract is the most common way to make an offer irrevocable. The offeree pays the offeror consideration, and in exchange the offeror agrees to keep the offer open for a fixed period. Most courts accept even nominal consideration. Once the option is in place, the offeror cannot revoke during the option period, and the offeree can accept or walk away. In a real estate deal or a business acquisition, paying for an option is usually worth the cost because it removes the risk that the other side disappears mid-negotiation.
Firm Offers Under the UCC
The Uniform Commercial Code creates a special exception for merchants dealing in goods. Under UCC § 2-205, a merchant who signs a written offer promising to keep it open creates a firm offer that cannot be revoked for the stated period, or for a reasonable time if no period is given, up to a maximum of three months. No consideration is required.2Legal Information Institute. UCC 2-205 – Firm Offers The rule applies only to merchants, meaning parties who regularly deal in the kind of goods involved. A one-time private seller does not get this protection. If the firm-offer language appears on a form the offeree supplied, the offeror must separately sign that specific term for it to be binding.
Part Performance on a Unilateral Offer
A unilateral contract is one where the offeror asks for performance rather than a promise. “I’ll pay you $5,000 if you paint my house” is the classic example. Under Restatement (Second) of Contracts § 45, once the offeree begins the requested performance, an option contract is created. The offeror can no longer revoke, and the offeree gets a reasonable opportunity to finish.3H2O. Restatement Second of Contracts Section 45 – Option Contract Created by Part Performance or Tender Merely preparing to perform does not trigger this protection. The offeree has to actually start the work itself.
Promissory Estoppel
Even without consideration or a signed writing, an offer can become irrevocable if the offeree reasonably relied on it and suffered real harm. Under Restatement (Second) of Contracts § 90, a court can enforce the offer when allowing revocation would be unjust. The remedy may be limited to actual losses rather than the full value of the promised deal.4H2O. Restatement Second of Contracts Section 90 – Promise Reasonably Inducing Action or Forbearance This comes up most often when a subcontractor relies on a general contractor’s bid, or when someone relocates for a job based on an offer that later gets pulled.
How to Actually Revoke an Offer
Getting the mechanics right is where revocation disputes usually arise. A revocation that technically happened but was not communicated properly may not count.
The Receipt Rule
A revocation of an offer is effective only when the offeree actually receives it. Sending a revocation letter is not enough; it must arrive. If you mail a revocation on Monday and the offeree accepts on Tuesday before your letter shows up on Wednesday, you are bound by the acceptance. Anyone revoking an offer should use a method that confirms delivery: overnight courier, certified mail with return receipt, or email with a read receipt.
The Mailbox Rule Asymmetry
Acceptance works on a different timing rule. An acceptance is effective when the offeree sends it, not when the offeror receives it. A revocation, by contrast, is effective only on receipt. So there is a window where the offeree has mailed an acceptance and the offeror has mailed a revocation, and the acceptance wins because it was dispatched first. This quirk has been part of contract law for over a century, and it consistently favors the offeree.
Indirect Revocation Through Third Parties
An offer can be effectively revoked without any direct communication from the offeror. Under Restatement (Second) of Contracts § 43, if the offeror takes definite action inconsistent with an intent to honor the offer, and the offeree learns about it from a reliable source, the power to accept is terminated.5Open Casebook. Restatement Second of Contracts Section 43 The action must be definite, not just negotiations with someone else, and the information must be reliable rather than rumor. If someone offers you a parcel of land, then sells it to another buyer, and a tenant on the property tells you about the sale, your power to accept the original offer is gone.
Documentation
Keep copies of everything. Save the sent email, the courier tracking confirmation, the certified mail receipt. If the revocation is oral, follow up with a written confirmation. In a dispute, the question is almost always when the other side received notice, and the answer depends entirely on what you can prove.
Walking Away From a Signed Contract
Once a contract is signed, you generally cannot back out unless the contract itself or the law gives you that right. Three mechanisms do most of the work.
Termination for Convenience
A termination-for-convenience clause lets one or both parties end the contract for any reason, usually with written notice within a specified number of days. These are standard in government procurement contracts, where the contracting officer can terminate performance whenever it serves the government’s interest.6Acquisition.GOV. 48 CFR 52.249-2 – Termination for Convenience of the Government (Fixed-Price) Private contracts use them too, particularly in ongoing service agreements. The clause needs precise language, including the required notice period and who can exercise the right. Vague language risks creating what courts call an illusory promise, where one party has no real obligation and the entire contract can be declared unenforceable.
Material Breach
When one side substantially fails to hold up its end of the bargain, the other side can treat the contract as terminated. Courts weigh how much of the expected benefit the injured party lost, whether money damages can adequately compensate, how likely the breaching party is to cure, and whether the breach reflects bad faith. A minor defect usually does not justify walking away from the whole deal. If the breach goes to the heart of what you bargained for and the other side shows no sign of fixing it, you are generally entitled to stop performing and pursue damages.
Liquidated Damages
Some contracts set the amount one party must pay if they exercise a right to terminate or otherwise breach. Courts enforce these clauses when the pre-set amount is a reasonable estimate of anticipated harm, especially where actual damages would be difficult to calculate. A clause will be struck down as an unenforceable penalty if the amount is grossly disproportionate to any realistic loss.7United States Department of Justice. Civil Resource Manual – Liquidated Damages Provisions The party challenging the clause carries a heavy burden. If the clause survives, the agreed amount is owed regardless of whether the injured party can prove actual damages.
Statutory Cancellation Rights for Consumers
Several federal laws give consumers a statutory right to cancel certain contracts within a cooling-off period, regardless of what the contract says. These rights exist because certain sales environments create pressure that leads to regret.
The FTC Cooling-Off Rule
The Federal Trade Commission’s Cooling-Off Rule, codified at 16 CFR 429, gives consumers three business days to cancel sales of consumer goods or services made anywhere other than the seller’s normal place of business. This covers door-to-door sales, purchases at trade shows, and transactions where a salesperson makes a pitch in your home. The seller must inform you of your cancellation right at the time of sale and provide two copies of a cancellation form. If they fail to provide the required notice, the cancellation period may extend until they comply.
The rule does not apply to purchases made entirely online, by mail, or by phone. It also excludes insurance, securities, and motor vehicles sold at temporary locations. The common belief that you can return any car within three days has almost no basis in law. Virtually no state provides a cooling-off period for automobile purchases.
Mortgage Rescission
The Truth in Lending Act gives borrowers a three-business-day right to rescind certain credit transactions secured by their principal residence.8Office of the Law Revision Counsel. 15 USC 1635 – Right of Rescission as to Certain Transactions This right covers refinances, home equity loans, and home equity lines of credit. It does not apply to the mortgage you take out to buy a home in the first place.9Consumer Financial Protection Bureau. Regulation Z 1026.23 – Right of Rescission
To rescind, you notify the lender in writing before midnight of the third business day after closing, after receiving the required disclosures, or after receiving notice of your right to rescind, whichever comes last. If the lender never provides those disclosures, the rescission right can extend up to three years.10eCFR. 12 CFR 1026.15 – Right of Rescission Once you rescind, the lender has 20 calendar days to return any money or property and release its security interest.
Other Cancellation Windows
Beyond the FTC rule and TILA, other laws provide mandatory cancellation periods. The Interstate Land Sales Full Disclosure Act gives purchasers of certain subdivision lots at least seven calendar days to revoke the contract. Most states provide a cooling-off period for timeshare purchases, typically ranging from five to ten days depending on the jurisdiction. Many states also require health clubs to allow cancellation of new membership contracts within the first few business days. These periods vary enough that you should check the specific rules for your type of purchase and location before assuming a cancellation window exists.
When Revocation Was Wrongful
If someone revokes a contract or offer without the legal right to do so, the injured party has several potential remedies. Which one applies depends on the nature of the deal and whether money can make the situation right.
The default remedy is expectation damages, which put the injured party in the position they would have been in if the contract had been performed. That typically means the difference between what was promised and what was actually received, plus consequential losses that were foreseeable when the contract was formed. If you had a contract to buy goods at $50,000 and the seller improperly revoked, your damages include the additional cost of buying equivalent goods elsewhere.
When expectation damages are too speculative to calculate, courts may award reliance damages instead, covering the out-of-pocket expenses the injured party incurred in reasonable reliance on the contract. This measure comes up frequently in promissory estoppel cases, where the Restatement allows courts to limit the remedy as justice requires.4H2O. Restatement Second of Contracts Section 90 – Promise Reasonably Inducing Action or Forbearance A subcontractor who spent $20,000 preparing for a project based on a general contractor’s bid might recover those preparation costs even if the lost profit on the full contract is impossible to pin down.
In rare cases, a court will order the breaching party to actually perform rather than pay damages. Under UCC § 2-716, specific performance is available for goods that are unique or where other circumstances make money damages inadequate.11Legal Information Institute. UCC 2-716 – Buyer’s Right to Specific Performance or Replevin Real estate contracts are the most common context because every parcel of land is considered unique. Courts will not order specific performance if it would impose disproportionate hardship on the defendant or require ongoing judicial supervision. The injured party also has a duty to mitigate, meaning you cannot sit on your hands and let damages pile up when a reasonable substitute is available.
