A proxy is a person authorised to act on behalf of another. In the context of a meeting of a Management Corporation (MC), a proxy is a person who is designated by an owner of a property to represent that owner at the meeting.
Generally, the proxy can do anything which the owner can do at the meeting himself – such as asking questions and voting.
Anyone can be appointed a proxy. The appointment of proxy must be made in writing. The form appointing the proxy must be deposited at the registered address of the MC at least
48 hours before the time fixed for the meeting.
