Can a Bank sue me for a loan they said I did not pay after 30 years, I live in West virginia

First its not a good idea to piggyback your question on someone else's. This can lead to confusion. You should start a new thread. So I've moved your question to its own thread.

Generally not. But your responsibility to pay never ends. They may not be able to sue you, but that can still try to collect.

All depends, when was your last payment or acknowledgement of the debt? Statute Of Limitations For Debts
