Common questions
Frequently Asked
5
What constitutes reasonable grounds for insecurity justifying a demand for assurance?+
Reasonable grounds arise from objective facts such as regulatory sanctions, asset sales, production halts, unpaid subcontractors, or public announcements of strategic shifts that threaten future performance. The demand must be in writing and the grounds must support a belief that the obligor will commit a total breach.
Supporting sources
When does failure to respond to a demand constitute repudiation?
Failure to provide assurance adequate under the circumstances within a reasonable time, not exceeding thirty days under the UCC, constitutes repudiation. Vague or noncommittal replies are inadequate when the insecurity stems from serious operational or regulatory problems.
Supporting sources
May a party suspend performance while awaiting assurance?+
Yes. If commercially reasonable or reasonable under the circumstances, the insecure party may suspend performance for which it has not yet received the agreed exchange until adequate assurance arrives. Suspension is justified even before any actual breach occurs.
Supporting sources
Does prior acceptance of defective performance waive the right to demand future assurance?+
No. Acceptance of an improper delivery or payment does not prejudice the right to demand adequate assurance of future performance when new grounds for insecurity arise.
Supporting sources
How does the doctrine apply outside sales of goods?+
The Restatement rule applies to all contracts and permits a demand for assurance when reasonable grounds exist to fear total breach. Courts have applied it to construction, service, and long-term supply agreements beyond the UCC.
