Liability insurance will protect the members from a special assessment if someone is injured, brings legal action and wins.
Directors and Officers Insurance (D&O) protects the Directors and Officers of the Association if they are found personally liable for anything. Typically this insurance kicks in when someone brings legal action against a Director (or all Directors) vs. against the Association. Without this insurance, the injured party can go after YOUR personal assets.
Crime Insurance acts as the Associations fidelity bond and covers issues of embezzlement by Directors, Officers or employees. Without this insurance, often required by the governing documents or State laws, the Association would have to eat the loss or try and recapture some of the embezzled funds by bringing legal action against the embezzler.
Per
FL 723.079, if applicable: "An association shall use its best efforts to obtain and maintain adequate insurance to protect the association and the park property upon purchase of the mobile home park. A copy of each policy of insurance in effect shall be made available for inspection by owners at reasonable times." What is deemed best efforts will likely be decided by a court if something happens that insurance, if you had it, would have covered and a member brings legal action against each Director for failing to obtain coverage.
Obviously the decision is that of the Board and the membership. Just be willing to deal with any consequences of the decision.
Hope this helps,
