I wouldn’t go near a situation where the trustees of the corporation have no idea what the term FIDUCIARY DUTY means.
You already exist in that situation. I have served on many municipal boards. Virtually no one on these boards or elected officials from your local zoning board to the Congress of the United States has even a passing recognition of the term “Fiduciary Responsibility”. If I had a dollar for every time I reminded board members I sat with of their fiduciary responsibility I’d be fairly well off.
