My ex-wife worked for a legal software firm. One thing to note is they were threatened with lawsuits ALL THE TIME, because, after all, their customers were lawyers. So any bug or whatever else would end up with some nasty email from some customer exclaiming, "We're going to sue!" In reality, not many (if any) actually carried through with it, but if that sort of threat makes you queasy, better be (or have) a really good lawyer yourself if you go this route, and not just as a domain expert for the software itself.
So true! I built a solution for a legal services outfit a few years ago. First bug they see, they want to sue you. Forget about working with the vendor to refine the solution. They just want to sue you. Never want to work with lawyers again.
