This kind of action by companies should be criminal, because they just destroyed economic activity worth at least $10000, because they didn't want to spend a little more on due diligence. Which could even have been put up as a bond by their client. My guess is that it would have cost <1 hour's work to validate this guy, and obviously he would rather bond that than lost the $10000. But no.
All this means is that the losing party must reimburse your costs. Your lawyer is going to ask for money while the case is ongoing. So you need to have some serious money in advance.
