Those that chose to make a moral statement on a thread about a legal issue - please note that the law sets statutes of limitation for a reason.

Making a payment on a debt that is out of the statute of limitations is a very large mistake but its arguable whether or not it actually restarts calculation of the statutes of limitation. Depends upon the jurisdiction.

However, it is a violation of state and Federal law to attempt to collect on a debt that is beyond the statutes of limitation, I do recommend a report to Colorado Attorney General.
