Much as I hate them, this sounds like material for a civil-criminal hybrid case. Looks like you were defrauded out of your source code and proceeds therefrom.

Much as I hate them, this sounds like material for a civil-criminal hybrid case. Looks like you were defrauded out of your source code and proceeds therefrom. If so, work on putting together a fraud/theft complaint and contact law enforcement. They have threshold amounts, so if it's over, say, $100k in losses, you'll interest them far more than if it's only $100 in losses. Don't lie, but don't understate, or assume you can't add up all the categories of loss into a larger number. A successful criminal prosecution may entitle you to recovery of restitution from the thief, with the litigation paid for nearly entirely by the government. As a bonus, you (through the government) get to threaten the other party with prison time, and they can neither discharge what they owe you in bankruptcy nor hide their money from a judgment near as easily. With this option on the table, seems rather foolish to even consider a civil lawsuit. Lawyers cost money, but criminal complaints are free. Now if only our system kept situations like these from happening where the victim lies to the government.
