Charles, please don't let the Directors and potential Directors know this little know fact

It is hard enough to find those few owners with a desire to serve their community! Of course there may be less danger in a volunteer HOA. That's because when an HOA has no "teeth" to enforce restrictions why would they try to the extent of evolking a suit.
Have you heard, "Directors have a fiduciary duty"? When there is a suit by a homeowner it may include the Association, the Board of Directors, and each and every Board member. That is why every Director should not only be covered by the HOA's insurance and protected by the "Corporation Shield" but should also add a rider to their personal homeowner's insurance. And most important they should always act in good faith and use good business judgement.
