In the US very few states have laws that specifically permit district attorneys to allow private collection agencies to collect checks in the district attorney's name. About half of all U.S. states offer some type of Bad Check Restitution Program, and these services vary in many ways. Some accept non-sufficient funds (NSF), and closed account checks while others may accept stopped payment checks and markers. It will also be noted that most have time limits (checks may need to be less than 90 or 180 days old and most need to be at least 30 days old and have had to have notice to check maker that the check has been returned unpaid with a demand for payment in a specified time). Some will not accept checks that were written under certain circumstances, including a post-dated check, one that the check writer asked the recipient to hold, or one that was written as an extension of credit.
