We do not recommend depositing a check into your customer’s account without their knowledge and indorsement.
Under the Uniform Commercial Code (UCC), your bank could be liable under its presentment warranties to the payor bank (the non-customer’s bank). When forwarding the check to the payor bank for payment, your bank is warranting that there are no missing indorsements. In this case, although your bank has stamped the check, the payee customer has not indorsed (or otherwise authorized) the deposit. Consequently, if the non-customer changes his mind about the deposit, he could pursue the issue with the payor bank, which may then turn to your bank for breaching its presentment warranty.
In addition, your bank also may face liability to your customer under your account agreement, unless it expressly permits your bank to deposit checks without the customer’s knowledge or indorsement. Your customers might prefer to reject certain payments and otherwise control the money deposited into their account. Thus, unless your account agreement permits your bank to deposit checks presented by someone other than your customer without your customer’s authorization and indorsement, your customer may make a breach of contract claim against your bank.
