Loss of a Quorum
The board of directors of a homeowner association may continue its meeting once a quorum has been achieved notwithstanding the subsequent loss of the quorum, provided any action is approved by at least a majority of the required quorum for the meeting. For example, a board of five directors needs three to establish a quorum. It then needs two of the three to approve any motion. If one of the three leaves the meeting, business may continue as long as the remaining two directors vote in unison.
Board members are required by law to perform their duties as directors. Attending meetings to conduct the business of the association is the primary duty of a director. Failure to attend meetings without good cause is a breach of that duty.
Board members can attend meetings by telephone or via Zoom provided all directors can hear and participate in discussions.
