I have 3 losses with over 100 wins as a pro se litigant with several appellate court victories. So let's start with the assumption I know what I am talking about. I have a fraudulent misrepresentation case with possible class action status and a RICO claim. This needs to be a contingency case although I can almost guarantee there would be a settlement offer quite early on because the ramifications of 1500 customers suing this business would BK them.
I have a four page attachment which clearly presents the facts, claims, technical information, list of key witnesses, and other relevant information for one to make an informed decision on this. Much easier to just read this first.
