The law speaks of the vergadering van eigenaars (owners' meeting); in practice it is often called the general members' meeting (ALV). It holds all powers that the law or the articles do not give to other bodies (article 5:125(1) BW). For example, it appoints and dismisses the board (article 5:131(2) BW).
All apartment owners have access to the meeting. Decisions are taken by an absolute majority of the votes cast, unless the articles provide otherwise (article 5:127(1) BW). Both the board and the chair may call the meeting (article 5:127(2) BW).
How you give notice, which period applies and which majorities are needed are set out in your regulations. From 1 January 2027 the meeting may also be held fully online or in a hybrid format, subject to conditions (article 5:127(4) to (11) BW).
