Being past SOL is tremendous LEVERAGE in obtaining a PFD - basically either take my offer (including deletion) or never collect a penny. Flip side is that you may have to 'live' with the baddie on your report for 7-7.5 years from DOLA/DOFD. Positive is that even if they try to sue - you can get it kicked by showing up and defending with past SOL.
The people that work at CA are not attorneys - so if past SOL, I would send to the CA's legal department along with to the general area - the legal dept will know what you are talking about at least.
