Repudiation of a contract is a clear signal, by words or by conduct, that one party will not perform their side of the agreement. When that signal is unmistakable, the other party can treat the contract as broken, stop performing, and pursue damages right away, even if the deadline for performance has not yet arrived. The rule comes from both the Uniform Commercial Code, which governs sales of goods, and general common law principles that courts apply to other kinds of contracts.
What Counts as Repudiation
Repudiation shows up in two forms. The first is an express refusal: a direct, unconditional statement that a party will not perform. A supplier who emails a buyer saying “I will not be delivering the materials we agreed on” has repudiated. No magic words are required. The statement just has to make the refusal unmistakable.
The second is repudiation through conduct. This happens when a party voluntarily does something that makes performance impossible. If someone contracts to sell a rare car to one buyer and then delivers that same car to someone else before the agreed sale date, the act is itself a repudiation. The conduct must be voluntary, and it must actually destroy the ability to perform, not just make performance harder or more expensive.
Courts use an objective standard. The question is not what the party privately meant, but whether a reasonable person hearing the words or watching the conduct would conclude that performance is being refused. A vague gripe about the deal or a request to renegotiate does not clear that bar. The refusal has to be definite enough that there is no realistic way to read it as anything else.
Repudiation Before Performance Is Due
Most disputes involve what lawyers call anticipatory repudiation: a repudiation that happens before the scheduled performance date. Under UCC § 2-610, when a repudiation substantially impairs the value of the contract to the other party, the aggrieved party can treat it as a breach immediately rather than waiting for the performance date to pass.1Legal Information Institute. Uniform Commercial Code 2-610 – Anticipatory Repudiation
The common law reaches the same place. The Restatement (Second) of Contracts, an influential treatise courts rely on, treats a repudiation before performance is due as giving rise to a claim for damages for total breach and discharging the other party’s remaining duties.
The practical effect is that you are not stuck in limbo. If a contractor tells you in January that they will not be building your addition in March, you can act on that refusal in January. You do not have to wait until March, watch the deadline pass, and only then start looking for a replacement.
Repudiation Versus a Minor Breach
Not every failure to perform is a repudiation, and the difference controls what you can do about it. A repudiation is a total breach: one that defeats the purpose of the agreement and denies the innocent party the substantial benefit they bargained for. A minor breach is a smaller shortfall that does not undermine the contract’s core purpose.
A homeowner hires a painter and specifies a premium brand of paint. If the painter uses a different but comparable brand without permission, that is likely a minor breach: the homeowner still gets a painted house and can recover for the deviation but cannot walk away from the contract. If the painter instead calls to say they have taken another job and will not be showing up at all, that is a repudiation. The homeowner gets nothing they bargained for.
The consequence of the distinction is concrete. After a repudiation, the innocent party can terminate the contract, stop their own performance, and sue for full damages. After a minor breach, the contract stays in force, and recovery is limited to the difference in value caused by the specific shortfall.
What You Can Do After a Repudiation
Once the other party has repudiated, you have real strategic choices. None of them is automatically right.
Accept the Repudiation and End the Contract
The most direct option is to treat the contract as over, stop your own performance, and pursue damages. Under UCC § 2-610, you can resort to any remedy for breach even if you earlier told the repudiating party you would wait for performance.1Legal Information Institute. Uniform Commercial Code 2-610 – Anticipatory Repudiation Acting on the repudiation also closes off the other party’s ability to take it back and force you into the original deal.
Affirm the Contract and Wait
You can also reject the repudiation, affirm the contract, and press the other party to perform. The UCC lets you wait for performance for a commercially reasonable time.1Legal Information Institute. Uniform Commercial Code 2-610 – Anticipatory Repudiation If the party ends up performing, the problem solves itself.
Waiting carries costs. Keeping the contract alive keeps the door open for the other party to retract. You also have to stay ready to perform your own side during the wait, which can tie up resources. And if things get worse while you wait, a court may later find that you should have acted sooner to limit your losses.
Demand Adequate Assurance
There is a middle path when you have real doubts about the other party but the situation has not yet become an outright refusal. Under UCC § 2-609, if you have reasonable grounds for insecurity, you can demand in writing that the other party provide adequate assurance of performance, and you can suspend your own performance while you wait for a response.2Legal Information Institute. Uniform Commercial Code 2-609 – Right to Adequate Assurance of Performance
What counts as adequate depends on the circumstances. It might be a written confirmation that delivery will proceed, a deposit, a letter of credit, or a performance bond. If the other party fails to give adequate assurance within a reasonable time, capped at 30 days under the UCC, that failure is itself treated as a repudiation.2Legal Information Institute. Uniform Commercial Code 2-609 – Right to Adequate Assurance of Performance The common law recognizes a similar right under the Restatement, though without the specific 30-day deadline.
What You Can Recover
The point of contract damages is to put you in the position you would have been in had the other party performed. The basic formula is the value of the performance you lost, plus incidental and consequential losses caused by the breach, minus any costs you avoided because you no longer had to perform.
When a Seller Repudiates
A buyer has two main paths. The first is cover: buying substitute goods in good faith and without unreasonable delay, then recovering the difference between the cover price and the contract price, plus incidental and consequential damages, minus expenses saved.3Legal Information Institute. Uniform Commercial Code 2-712 – Cover – Buyer’s Procurement of Substitute Goods
If the buyer does not cover, they can instead recover the difference between the market price at the time they learned of the breach and the contract price, again plus incidental and consequential damages and minus expenses saved.4Legal Information Institute. Uniform Commercial Code 2-713 – Buyer’s Damages for Non-Delivery or Repudiation The buyer can cancel the contract and recover any part of the purchase price already paid.5Legal Information Institute. Uniform Commercial Code 2-711 – Buyer’s Remedies in General
When a Buyer Repudiates
A seller can recover the difference between the market price at the time and place for tender and the unpaid contract price, plus incidental damages, minus expenses saved. If that formula does not make the seller whole, the seller can instead recover lost profit, including reasonable overhead.
Services, Real Estate, and Other Non-Goods Contracts
For contracts outside the UCC, the same expectation principle applies under common law. The injured party recovers the value of the lost performance, plus consequential damages such as lost profits or reliance costs, minus costs they no longer have to incur. The exact numbers depend on the type of contract, but the underlying logic is the same.
Your Duty to Minimize the Loss
You cannot sit back, let losses pile up, and expect to recover everything. The law requires you to take reasonable steps to reduce the harm. This is the duty to mitigate.
The standard is reasonableness, not perfection. You do not have to accept an unreasonable substitute, take on real risk, or humiliate yourself to cut losses. You do have to make a genuine effort. A buyer whose supplier repudiates should look for replacement goods at a reasonable price. A landlord whose tenant repudiates a lease should make reasonable efforts to re-rent.
Failing to mitigate reduces your damage award by the amount you could have avoided with reasonable effort. In some jurisdictions, a complete failure to mitigate wipes out recovery for avoidable losses entirely. The other side of the rule protects you: a reasonable but unsuccessful attempt to mitigate is not held against you.
When the Other Side Can Take It Back
A repudiation is not always final. Under both the UCC and common law, the repudiating party can retract, but only within a narrow window.
Under UCC § 2-611, retraction is available until the repudiating party’s next performance is due, but only if the aggrieved party has not already canceled, materially changed their position in reliance on the repudiation, or indicated that they consider the repudiation final. The retraction can be communicated by any method that clearly shows intent to perform, and it must include any assurance of performance that was justifiably demanded under UCC § 2-609.6Legal Information Institute. Uniform Commercial Code 2-611 – Retraction of Anticipatory Repudiation
The common law rule under the Restatement is similar. A retraction cancels the repudiation if the injured party receives notice before they materially change position or indicate they consider the repudiation final.
A successful retraction reinstates the party’s rights under the contract but does not erase the disruption, and the repudiating party must account for any delay their repudiation caused.6Legal Information Institute. Uniform Commercial Code 2-611 – Retraction of Anticipatory Repudiation In practice the window closes fast. If a supplier repudiates a delivery contract and the buyer immediately signs with a different supplier, the buyer has materially changed position, and the original supplier’s chance to retract is gone.
Defenses to a Repudiation Claim
Not every refusal to perform is legally unjustified. A party accused of repudiation may have a valid defense if circumstances genuinely prevented performance.
- Impossibility of performance. If an event outside the party’s control destroyed the subject matter of the contract or the means of performing it, and the event was not foreseeable when the contract was signed, performance may be excused. Courts apply this defense narrowly. Financial difficulty alone almost never qualifies. The event must make performance truly impossible, not just more expensive or inconvenient.
- Frustration of purpose. Even when performance is still physically possible, a court may excuse it if an unforeseeable event has destroyed the fundamental reason the contract existed. The classic example is renting a room to watch a parade that gets canceled. The room is still available, but the point of the deal is gone.
- Prior breach by the other party. If the party demanding performance committed a material breach first, refusing to continue may be justified rather than repudiatory. You generally cannot insist on performance from someone whose obligations you have already undermined.
These defenses are fact-intensive, and courts vary in how broadly they apply them. The party raising the defense carries the burden of proving the circumstances genuinely excused their nonperformance.
