Common questions
Frequently Asked
4
When may a party demand adequate assurance of performance?+
A party may demand adequate assurance when reasonable grounds for insecurity arise with respect to the other's future performance. Objective facts such as canceled events, regulatory sanctions, or visible lack of progress supply those grounds. The demand must be in writing under the UCC.
What makes an assurance adequate under the circumstances?+
An assurance is adequate when it supplies concrete commitments or information that reasonably restores confidence in performance. Vague statements of confidence or general optimism do not qualify when the insecurity stems from serious operational problems. Commercial standards between merchants guide the adequacy determination.
What happens if the demanded assurance is not provided?+
Failure to provide adequate assurance within a reasonable time constitutes repudiation of the contract. The insecure party may then cancel and pursue remedies such as cover. The time limit is thirty days under the UCC.
Does prior acceptance of nonconforming goods bar a later demand for assurance?+
No. Acceptance of any improper delivery or payment does not prejudice the right to demand adequate assurance of future performance. Each demand is evaluated on its own facts when new grounds for insecurity appear.
