I respect the answers already given -- all good. I have some suggestions to add which I hope are of use to you.
Firstly, I notice you're CEO of Student Consulting Group. Does that mean your circle would include law students, and academics, with access to legal resources, libraries etc.? If so, receptive ears may be nearby to help.
Secondly, (you don't need to answer this on the forum), does the nature of the legal claims being made indicate the value of the startup and its goals, or are the claims tangential to your business. If people are using legal means to block your progress it can be a good signal. [Consider AirBnB and the hotel regulation business as an example]. You may be able to raise funds partly by such circumstances.
Thirdly, when there are disagreements role playing can be an effective way of seeing the problem from both sides. It costs very little and can feel silly. You get together your trusted team, you play the plaintiff and simulate the argument, the process and procedures and work it through. At the end you note down the what and why of the situation. Maybe re-run it with a different strategy. You are just trying to gain insights which might have been absent and got things to where they are at the moment.
I wish you success and good luck!
