You should securely store each original check at least 30 calendar days from the date the image was submitted and accepted. Please note that you are solely responsible and liable for the security and storage of the original checks and for any loss or misappropriation of these checks. After the 30 days, you may dispose of the check in a manner that will ensure the check will not be presented again (such has shredding), mark the check as “Electronically Presented” or “VOID,” or you may continue to securely store it in order to ensure that it is not presented again for payment.
