We have a (former) customer who has continued to write checks off an account that we closed 8 months ago. To date, he has written about 50 checks totaling over $10,000. Is this a SAR event? All the checks are returned "account closed" and the bank is not taking a loss, which I know is not a factor. To some extent, I feel like the check fraud is against the merchants who are accepting the checks and not against the bank. How do other banks deal with this issue?
