If you have submitted your written resignation of a corporation as its CFO and the board members have yet to remove your name as having any affiliation with this corporation, I would write all of the governmental entities that you have listed in your question stating that you are no longer affiliated with this corporation effective a certain date.Send a copy of the letter to all of the corporation's board members and keep a copy of the letter for future reference.As to having any legal recourse presently for the board's inaction, you do not. You have yet to be damaged.
