Iowa Code § 554.13514: Waiver of lessee’s objections.

1. In rejecting goods, a lessee’s failure to state a particular defect that is ascertainable by reasonable inspection precludes the lessee from relying on the defect to justify rejection or to establish default:

a. if, stated seasonably, the lessor or the supplier could have cured it (section 554.13513); or

b. between merchants if the lessor or the supplier after rejection has made a request in writing for a full and final written statement of all defects on which the lessee proposes to rely.

2. A lessee’s failure to reserve rights when paying rent or other consideration against documents precludes recovery of the payment for defects apparent in the documents.
