Can be sued after they charge off the debt?

Yes, Absolutely! I was and a judgment was AWARDED against me. Now in order to protect my paycheck, I have to make payment arrangements or risk garnishment of my checking account. HERE IS SOUND ADVICE - Make payment arrangements and make the payments as agreed.

But only if the it occurred within the statute of limitations which varies by state. If the statute of limitations has past they are out of time, but if you make payment arrangements you may actually reaffirm the debt and then you would have to pay. I was out of work about 10 years ago had some bills which I would never be able to pay, when I finally got back working I was making just above minimum wage and it took almost 4 years to get back to where I was financially. The statute of limitation was past in my state so they call me from time to time, but they can't collect and they can't put it back on my report so long as I don't reaffirm the debt by making a payment arrangement. My advice is if you are in a bind to contact legal aide if you qualify or an attorney for advice for your state.
