Liability is the big answer!
Sometimes, homeowner-HOA disagreements result in lawsuits against the HOA. Not infrequently, such suits also name one or more HOA board members. Without adequate Directors and Officers (D&O) insurance, a lawsuit against an HOA board member can leave the member responsible for paying legal costs, expenses, and even damages. Since no prospective board member wants to risk going broke as a result of acting on the board, in order for an HOA to attract and keep good board members, adequate D&O insurance is a must.
