§ 336.2A-401 — Insecurity; Adequate Assurance of Performance

Plain-Language Summary

Each party to a lease contract owes the other an obligation not to impair the other's expectation of receiving the performance they are due. If reasonable grounds for insecurity arise about the other party's performance, the worried party may demand in writing adequate assurance that performance will happen and may, if commercially reasonable, suspend its own performance until that assurance is received. If adequate assurance is not provided within a reasonable time (not more than 30 days after the demand is received), the failure is treated as a repudiation of the lease.

Practical Notes
If you have a genuine reason to doubt that the other side will perform under a lease, you can send a written demand for adequate assurance and hold off on your own performance until you get it. The other party must respond within a reasonable time, capped at 30 days, or they are treated as having repudiated the lease. Between merchants, the reasonableness of the doubt and the adequacy of the assurance are judged by commercial standards, and accepting a prior nonconforming delivery or payment does not waive the right to demand assurance of future performance.
