Can’t be that long ago...2 years is usually the limit in cases like this. Did they demand from you? or your insurance company? If they are looking for a payout they will be expecting you to give it to your insurance who, based on the case, either fight it (if it costs little to do) or they’ll buy out to the limit of your policy.
It depends on how you found out about this, I guess. If they are asking for millions and don’t have some reasonable evidence of bills and disability, I’d wait and consult with my insurance. Likely they just want a quick payout of what the insurance company is willing to piss away.
I’d also like to say that if it were me that was called by them, or their “lawyer” I’d tell them to get in line with the rest of the creditors in the bankruptcy case, laugh heartily, and then hang the eff up.
If there is any communication, it keeps it open...
