Common questions
Frequently Asked
4
What constitutes reasonable grounds for insecurity justifying a demand for assurance?+
Objective facts such as a key subcontractor's bankruptcy causing major delays, visible lack of progress at a work site, unpaid subcontractors, or regulatory warnings halting production can create reasonable grounds. Vague statements of commitment or optimism do not dispel those grounds when concrete details about recovery plans are missing.
Supporting sources
When is a response to a demand for assurance considered inadequate?+
A bare statement of confidence or general commitment without timelines, plans, or financial backing is inadequate when the insecurity stems from concrete problems like staff cuts or production halts. Commercial standards between merchants or the specific circumstances of the contract determine adequacy.
Supporting sources
What happens if adequate assurance is not provided after a justified demand?+
Failure to provide adequate assurance within a reasonable time may be treated as a repudiation of the contract. The demanding party may then pursue remedies for total breach, including covering and seeking damages.
Supporting sources
Does accepting an improper delivery waive the right to demand assurance later?+
No. Acceptance of any improper delivery or payment does not prejudice the aggrieved party's right to demand adequate assurance of future performance when new grounds for insecurity arise.
