A contractual right that permits one party to demand written assurance of due performance when reasonable grounds for insecurity arise concerning the other party's ability or willingness to perform. The demanding party may suspend its own performance until adequate assurance is received if commercially reasonable to do so. Failure to provide adequate assurance within a reasonable time constitutes a repudiation of the contract.
BlueWave Shipping chartered a vessel from HarborLine under a one-year agreement. After the vessel twice failed safety inspections and was detained by port authorities, BlueWave sent a written demand for documentation confirming repairs and seaworthiness. HarborLine responded only that repairs were ongoing. BlueWave suspended hire payments and chartered a substitute vessel.
ARB contracted to purchase specialized equipment from E-Systems. When the delivered equipment failed to meet express quality warranties, ARB withheld payment and demanded written assurance that future deliveries would conform. E-Systems provided no response addressing the warranty concerns. ARB treated the lack of assurance as a repudiation and refused further payment.
In the late 1960s the A.C. Neilson Company began replacing written diaries with electronic equipment attached to television sets that fed audience data directly into computers via telephone lines. In early 1973 ARB (American Research Bureau), Inc., Neilson's leading competitor in television and radio audience research, concluded it had to adopt the same technology and circulated a request for proposals among electronics manufacturers. E-Systems, Inc. (Melpar Division), a designer and manufacturer of defense and communications electronics, responded along with three other companies. On the basis of E-Systems's representations the parties signed a fifty-three-page contract in October 1973 after lengthy negotiations by experienced counsel. The contract set a seven-stage work schedule tied to payments and deliverables, including Deliverable 1 (detailed electrical design) due in mid-November 1973, Deliverable 4 (fully operational pre-production models) due from late December 1973 through early February 1974, and Deliverable 7 (production equipment shipments) due in spring and summer 1974. The first pre-production model arrived on December 21, 1973, but testing disclosed performance defects. E-Systems assured ARB the problems would be cured at the production stage, so work continued through the summer of 1974 with deliveries of equipment that ARB installed in sample households. Those installations proved largely unsuccessful. In October 1974 ARB filed suit in the District Court for the District of Columbia. In its complaint ARB alleged that the equipment designed and produced by E-Systems did not conform to the specifications of the contract, and that E-Systems had breached express and implied warranties of merchantability and fitness. E-Systems answered that the equipment it produced did, in fact, work properly, and counterclaimed for the money owed under the contract. ARB then added a count of misrepresentation, contending that E-Systems negligently misrepresented the results of a pre-contract feasibility test run on the equipment, and E-Systems added a count seeking reformation of the contract, alleging that between negotiation and formal presentation ARB had altered agreed-upon contract terms. On September 19, 1977, by consent of the parties and upon order of the district court, a special master was appointed to conduct the trial. A five-week trial followed with extensive pre- and post-trial briefing. In his Memorandum Opinion of November 15, 1978, the master held that the equipment supplied by E-Systems had substantial defects and that E-Systems had breached the contract and warranties thereunder. On March 2, 1979, after considering written and oral objections of both parties to the master's Memorandum Opinion, the district court issued a Memorandum and Order, adopting the opinion of the master in full and ordering judgment for plaintiff. Both parties appealed to the United States Court of Appeals for the District of Columbia Circuit.
Reasonable grounds exist when objective facts create a substantial doubt about the other party's future performance, such as repeated inspection failures, financial distress, loss of key subcontractors, or vague responses to performance inquiries. The grounds are evaluated under commercial standards between merchants. A justified demand triggers the right to suspend performance until assurance arrives.

An adequate response must provide concrete commitments, documentation, or timelines that dispel the insecurity under commercial standards. Vague statements of ongoing efforts or general commitment are insufficient when prior defects or delays have occurred. Between merchants, adequacy is judged by trade usage and the specific circumstances creating the insecurity.
Supporting sources
Failure to provide adequate assurance within a reasonable time, not exceeding thirty days under the UCC, constitutes a repudiation. The demanding party may then treat the contract as breached and pursue remedies including suspension of performance, cover, or damages. The repudiation excuses the demanding party's further performance.
Supporting sources
No. Acceptance of an improper delivery or payment does not prejudice the right to demand adequate assurance of future performance. Each demand is assessed independently based on new grounds for insecurity that arise after acceptance.
