Definition
A method allowing a member who can't attend a meeting to authorize someone else to represent their vote and count toward quorum.
A proxy lets a member who can't attend a meeting still participate. In writing, they authorize another person — often the board or another owner — to cast their vote and count them toward quorum.
Proxies are governed by your bylaws, which define whether they're allowed, the required form, whether they're general (holder decides) or directed (member specifies the vote), and when they expire. Because mishandled proxies are a frequent source of disputed results, the paperwork must be done carefully.
