What characterizes "forged on-us checks"?

Forged on-us checks are specifically characterized by being drawn on the same financial institution where they are presented for payment. This means that they are processed at the bank that issued them, which is the defining factor for this type of check. When a check is presented for payment at the same bank that issued it, any forgery or alteration becomes apparent during the processing, creating unique challenges for the financial institution.

Checks drawn from a foreign bank would not fit this definition, as they involve a different jurisdiction and processing channels. Checks used for online payments also do not qualify as on-us checks because they are not physical transactions being negotiated at a bank. Checks signed by an unauthorized person are relevant to the issue of forgery; however, the term "on-us" specifically refers to where the check is presented, rather than the legitimacy of the signature itself. Thus, the correct identification of "forged on-us checks" is closely linked to their negotiation at the issuing bank.
