Am I correct in assuming you are not a US citizen nor do you have assets in the US? But the investor and debt holders are in the US? If all of this is true, effectively, I have a hard time imagining anyone pursuing you legally. Just too expensive. There are a lot of other questions that come into play here - for example, is the angel investor a shareholder or do they have some sort of convertible security? Startups go out of business all the time - the vast majority do. Your investor should know that, as should you debt holders. This should be a simple process, but it seems like it's been dragged out way beyond what you should have to do with. I'm a bit nervous that the investor's lawyers did your corporate documentation and you don't have it. I'm concerned that you may have been taken advantage of. I would write the investor's lawyer and request copies of the documentation. He cannot withhold it because you didn't pay some legal bill. If you want to take the risk, just send the investor a notice that you are quitting any position you have (director/officer/employee) of the company. And then just forget the whole thing. If you want to mitigate risk, I'd find a lawyer who works with startups who can hopefully help you navigate this in a cost-efficient way.
