what is the statue of limitations in the state of tenneessee for some collecting a debt on a utility bill?

Question

the gas company told us that we still owe a bill for the year 2000.
they have never mentioned this before

Answer 1

Utility bills fall under U.C.C. UCC SOL will apply in this case

Answer 2

It's statute, and what I would do is make them show YOU that it hasn't expired. Let them do the work if they think you owe them.
