an Umbrella protects you to a greater extent and most provide a lawyer to defend the suit. 

If you were to take him to court, is the company established enough and have enough assets that he'd think it would be worthwhile defending himself vs. just closing up shop and starting a new company?

Once the  players were known, some of us jumped in to defend y'all, as fortunately your reputations are so good it was somewhere between unlikely and inconceivable that you were at fault.

Board of Realtors is defending the rights of property owners....

Bill Gulley speech class haha I must defend myself, I work an overnight job as well, sleep deprivation is responsible for the grammatical errors.

I have a title guy I work with who will be letting me know if there is an IRS lien on the property, but they did list the IRS as an "added defendant" (their term for anyone else that has a claim against whoever's being sued for foreclosure) so I'm assuming these people owe something to the IRS, not related to the foreclosure of their home.

I believe these deals need to appear to be reasonable to a judge if you ever find yourself in court defending your position, but that's just me. 

@Michael Wentzel A judge friend of mine once told me to never draw up a Deed of Trust that I couldn't personally defend in court.
