We received notice from our customer that the intended payee of a check did not receive the funds, however the check was negotiated approximately 2 years ago. The only indorsement on the check appears to be from the depository bank: Credit to the Acct of the Named Payee". The payee happens to be a large corporation, and therefore just notified our customer of the non-payment. The payee will not sign an affidavit. As our team has been discussing this situation, we have a couple questions. In review of the sample breach of warranty document from ECCHO, the document does not appear to require an affidavit or other documentation from the payee to submit to the depository bank with the claim. Is this required to submit a breach of warranty, or is this a document we should have for our own records? I have read other threads that state an affidavit of missing indorsement is required from the payee. What are some of the risks of submitting a breach of warranty claim? What are the risks of not submitting a claim? Any other considerations or feedback is appreciated!
