Q: Myself and my ex were contacted about a 14 year old debt. What can we do about it?
A: I would send them a certified letter telling them that you dispute the debt and instructing them not to contact you about the debt. Their conduct is a violation of state and federal law. If they do contact you, keep a log of who is calling you, when, the time and date, and where they are calling you from. You should then to talk an attorney or the state about the harrassing behavior.
Also, be sure to get a copy of your credit report and dispute the debt if it is on your report.
