You (and possibly other shareholders) need to get an attorney ASAP, preferably one who is familiar with both bankruptcy suits and also corporate law. You will want to act immediately: based on your description there is a possibility that you will want to sue one or more officers or directors on a personal basis, and you may need to take prompt steps to secure your assets.
Because it is in bankrupcty there is an automatic stay, and that is yet another reason to get counsel. pro se parties can get in a lot of trouble when bankruptcy is involved, because stay violations are expensive.
Do you want accurate, personalized, legal advice that you can rely on? You will have to hire an attorney, not ask on Avvo. I am not your attorney and am not creating an attorney-client relationship by this post. I am therefore giving only general advice. This advice may not apply to you or your situation; may not take account of all possibilities, and may not match the advice I would give to a client. DO NOT rely on this advice or any other advice on Avvo to make your legal decisions. If you want an answer to a legal question you should retain an attorney who is licensed in your state.
Do you have a question? If you need to act quickly, you should be contacting lawyers who handle these matters. Obviously, your issues are nothing to be addressed on a website like this.
