before you waste any money, read your iso agreement fully.One funder told me only 1 in 10 iso even ask to get the counter signed. I know some agreements have clauses that you need to submit/fund a new deal every x amount of days so if you didnt at any point from when you both signed ,you are not even an iso of theirs. Next if the iso agreement is solid , you need to make sure your proof is solid and that is was not a shopper that they can easily say they got it from someone else.
Best of luck and Please update us what happens as i have been in this industry since 07 and do not know of one case of an iso actually winning in court vs a funder

Best point you make here is about getting ISO agreements back countersigned. I would bet it is less than 1 in 10, meaning the vast majority of ISO's have no protections from getting screwed over. Do not submit deals to funders until you have a fully executed and valid iso agreement signed
