Yes you can file suit but whether you will be successful in favorable judgment for you and against the CFO depends on various factors, including but not limited to the company bylaws or operating agreement, fiduciary responsibilities and violation thereof plus all this in light of the law. As Counsels mentioned, the best advice is to seek help from a local business litigation Attorney. Good luck to you.
