Every debt that appears on your credit report begins with an opening date. It's from that date or the last payment date that your statute of limitations begins and ends. Once the statute of limitations is over, the debt does not belong on your credit report and also, you can not be sued for that debt. What some debt collectors will do is re-age the debt and put a new opening date on your credit report so the statute of limitations begins again and they believe they can sue you again. Keep an eye on those opening dates.
