If you honestly believe that you have been overpaid for unemployment benefits, you should return the excess payment explaining that you believe that you were overpaid for your claim.Keep a copy of the letter and check sent for future reference. By returning the money, it shows that you were not being dishonest and that you caught the apparent mistake before anyone with unemployment did. By doing this, you will sleep a lot better and not be worried about possible problems with the law.If you do not return the amount that you believe you were overpaid for, there may be a time in the future that a refund will be required of you.Good luck.
