A credit collections agency is pursuing a debt that I believe to be outside the statute of limitations. I have two questions related to debt collection statute of limitations (see details).

It’s an old cell phone bill, really long messed up story involving a psychotic ex. Anyway, I never had any money to pay them and now I think it’s been 7 years since ATT&T sent the bill to collections.

Each state has its own limits; does the statute apply to the state in which I first generated the debt or to the state in which I now reside? Does the debt time start when the debt is first sent to collections, or before that, when I fell behind with the company (when service was terminated, but the bill still belonged to ATT&T)?
