Thank you for your question. I look forward to working with you to provide you the information you are seeking for educational purposes only.
One option is you have to file a shareholder derivative action, which means you need an attorney to sue the two of them for self dealing, fraud, embezzlement and breach of fiduciary duty
to the corporation. This is the common way to get control and seek to cease the activity you are complaining about. Once the shareholder derivative action is filed you can file a motion for injunction to get control over the accounts and assets of the corporation to stop them from continuing to harm the corporation. But this mandates an attorney filing because you cannot sue on behalf of the corporation, which is what you have to do to get what you are seeking.
The only other option is you have to bring the proof of them stealing from the corporation to the local district attorney for them to review to determine whether or not they want to prosecute. The DA has a right to refuse to prosecute and to send you to civil court to sue them as I mentioned in option 1.
So, the only way out of this is going to be suing in court if you do not want to walk away from them and to seek to get control and seek damages from them for the money they have stolen from the company (and you) back.
As far as getting an attorney, you may get an attorney who would agree to take the case on a contingency basis in exchange for a share of any proceeds he can get for you in the case and likely a lien on the house. You would have to negotiate that with the attorney individually and you can locate a corporate attorney at the same sites used by other attorneys, http://www.hg.org or http://www.lexmundi.com
