A decision only counts if it was properly called, properly recorded, and can be shown later. That is mostly a paperwork problem.
Disputes in societies rarely turn on whether a decision was sensible. They turn on whether notice was given, whether quorum was met, and whether anyone wrote it down.
AGMs need clear notice to every member, sent and evidenced — not a poster in the lift.
Items circulated in advance, so nothing is sprung at the meeting.
Notices go by email and WhatsApp as well as the app, with a record of who was sent what.
Resolutions recorded against the agenda and kept in the minutes book.
For matters that need a vote without assembling everyone, with the result recorded.
Who holds which office and since when — asked for more often than you would expect.
When a member challenges a decision two years on, the answer is a notice, an agenda, an attendance and a minute — not a recollection.
On a managed plan a dedicated accountant does the work and your committee approves it.
