Sure, file a police report. Do some research, I believe there’s a process * for sure…( I’m certain someone at your local police station can help you) I didn’t bother. I stopped accepting checks sometime in 2009. I think the total for 3 years was about $500 or so. I wrote it off as bad debt last year.
There are resources, your bank may know, who will purchase your debt (provided its within the SOL). I didn’t bother because they’ll want to buy it for pennies on the dollar, and your business will be the blame line for the debt collectors to collect full payoff + fees. I have not read the latest changes, but as of a few years ago, you could only blemish their credit report if the original amount was above $70 or so. Lots of BAD debt collectors get around this by adding their FEE and filing it as a LOAN - which is illegal. Bad check for $20?? Unless you can hound them at their house, pretty much uncollectable, unless the po-lice go after them.
Good luck. STOP accepting checks, nowadays, all checking accounts come with a debt card option. If its a business, by VERY suspect. It has not been a good few years for businesses or individuals in the economy, and checks are… just don’t accept any. Anymore!
