(c) the aggrieved party has no legitimate interest in refusing cure; and

(d) cure is effected promptly.

1. General principle


Paragraph (1) of this Article provides that, if certain conditions are met, the non-performing party may cure by correcting the non-performance. In effect, by meeting these conditions, the non-performing party is able to extend the time for performance for a brief period beyond that stipulated in the contract, unless timely performance is required by the agreement or the circumstances. This Article thus favours the preservation of the contract. It also reflects the policy of minimising economic waste, as incorporated in Article 7.4.8 (Mitigation of harm), and the basic principle of good faith stated in Article 1.7.


This Article is related to the cure provisions contained in Articles 37 and 48 CISG and in some domestic laws governing contracts and sales. Even many of those legal systems that do not have a rule permitting cure would normally take a reasonable offer of cure into account in assessing damages.


2. Notice of cure


Cure may be effected only after the non-performing party gives notice of cure. The notice must be reasonable with regard to its timing and content as well as to the manner in which it is communicated. Notice of cure must be given without undue delay after the non-performing party learns of the non-performance. To the extent information is then available, the notice must indicate how cure is to be effected and when. Notice must also be communicated to the aggrieved party in a manner that is reasonable in the circumstances.


Notice of cure is considered to be “effective” when the requirements of paragraph (1)(a) - (c) have been met.


3. Appropriateness of cure


Whether cure is appropriate in the circumstances depends on whether it is reasonable, given the nature of the contract, to permit the non-performing party to make another attempt at performance. As indicated in paragraph (2), cure is not precluded merely because the failure to perform amounts to a fundamental non-performance. The factors to be considered in determining the appropriateness of cure include whether the proposed cure promises to be successful in resolving the problem and whether the necessary or probable delay in effecting cure would be unreasonable or would itself constitute a fundamental non-performance. However, the right to cure is not defeated by the fact that the aggrieved party subsequently changes its position. If the non-performing party gives effective notice of cure, the aggrieved party’s right to change position is suspended. Nonetheless, the situation may be different if the aggrieved party has changed position before receiving notice of cure.


4. The aggrieved party’s interest


The non-performing party may not cure if the aggrieved party can demonstrate a legitimate interest in refusing cure. However, if notice of cure is properly given and if cure is appropriate in the circumstances, it is presumed that the non-performing party should be permitted to cure. A legitimate interest may arise, for example, if it is likely that, when attempting cure, the non-performing party will cause damage to person or property. On the other hand, a legitimate interest is not present if, on the basis of the non-performance, the aggrieved party has simply decided that it does not wish to continue contractual relations.




1. A agrees to construct a road on B’s property. When the road is complete, B discovers that the road grade is steeper than the contract permits. B also discovers that, during construction, A’s trucks caused damage to B’s timber. A gives notice of cure to regrade the road. Even if cure would otherwise be appropriate in the circumstances, B’s desire to prevent further damage to the timber may provide a legitimate interest for refusing cure.


5. Timing of cure


Cure must be effected promptly after notice of cure is given. Time is of the essence in the exercise of the right to cure. The non-performing party is not permitted to lock the aggrieved party into an extended waiting period. The lack of inconvenience on the part of the aggrieved party does not justify the non-performing party in delaying cure.


6. Proper forms of cure


Cure may include repair and replacement as well as any other activities that remedy the non-performance and give to the aggrieved party all that it is entitled to expect under the contract. Repairs constitute cure only when they leave no evidence of the prior non-performance and do not threaten the value or the quality of the product as a whole. It is left to the courts to determine the number of times the non-performing party may attempt a cure.




2. A agrees to install an assembly line for high temperature enamel painting in B’s factory. The motors are installed with insufficient lubricant and as a result “lock up” after a few hours of operation. A replaces the motors in a timely fashion, but refuses to examine and test the rest of the equipment to ensure that other parts of the line have not been damaged. A has not effectively cured.


7. Suspension of other remedies


When the non-performing party has given effective notice of cure, the aggrieved party may, in accordance with paragraph (4), withhold its own performance but, pursuant to paragraph (3), may not exercise any remedies inconsistent with the non-performing party’s right to cure until it becomes clear that a timely and proper cure has not been or will not be effected. Inconsistent remedies include giving notice of termination, entering into replacement transactions and seeking damages or restitution.


8. Effect of a notice of termination


If the aggrieved party has rightfully terminated the contract pursuant to Articles 7.3.1(1) and 7.3.2(1), the effects of termination (see Articles 7.3.5, 7.3.6 and 7.3.7) are also suspended by an effective notice of cure. If the non-performance is cured, the notice of termination is inoperative. On the other hand, termination takes effect if the time for cure has expired and any fundamental non-performance has not been cured.


9. Right of aggrieved party to damages


Under paragraph (5) of this Article, even a non-performing party who successfully cures is liable for any harm that, before cure, was occasioned by the non-performance, as well as for any additional harm caused by the cure itself or by the delay or for any harm which the cure does not prevent. The principle of full compensation for damage suffered, as provided in Article 7.4.2, is fundamental to the Principles.


10. The aggrieved party’s obligations


The decision to invoke this Article rests on the non-performing party. Once the aggrieved party receives effective notice of cure, it must permit cure and, as provided in Article 5.1.3, cooperate with the non-performing party. For example, the aggrieved party must permit any inspection that is reasonably necessary for the non-performing party to effect cure. If the aggrieved party refuses to permit cure when required to do so, any notice of termination is ineffective. Moreover, the aggrieved party may not seek remedies for any non-performance that could have been cured.




3. A agrees to construct a shed on B’s property in order to protect B’s machinery from the weather. The roof is constructed in a defective manner. During a storm, water leaks into the shed and B’s machinery is damaged. B gives notice of termination. A gives timely notice of cure. B does not wish to deal further with A and refuses the cure. If cure is appropriate in the circumstances and the other conditions for cure are met, B cannot invoke remedies for the faulty construction but can recover for damage caused to the machinery before the cure was to be effected. If cure is inappropriate in the circumstances, or if the proposed cure would not have solved the problem, the contract is terminated by B’s notice.
