Below is a bunch of information relevant to owners in a Sectional Title Scheme. This information is often misunderstood and all owners should be aware to prevent mistakes.
A "Sectional Title Scheme" is a legally registered entity for a building/property that is owned by multiple owners and registered at the Deeds Office.
The term "Body Corporate" is simply a collective name given to all the owners of a Sectional Title Scheme combined.
The Body Corporate is NOT separate from the owners, every owner is a member of the Body Corporate.
The "Trustees" are owners and members of the Body Corporate just like all other owners.
It is impractical for every decision to collectively be made by all owners on a daily basis. The owners as a group (the "Body Corporate") therefore elected the Trustees and entrusted them to deal with day-to-day decisions on their behalf for the financial year.
Trustees are not employed or paid and serve on a voluntary basis in their spare time. They have their own full-time jobs.
The TRUSTees are trusted by the owners to look after the property to the beast of their ability.
The "Managing Agent" is a company appointed by the Trustees on behalf of the Body Corporate (the Owners) to deal with most administrative and financial aspects on a day-to-day basis. They do all the admin work. The Managing Agent does NOT have any decision-making power and can only act on instruction from the Trustees.
The Managing Agent typically assigns a "Portfolio Manager" to a building to ensure continuity. Most Portfolio Managers manage 20+ buildings and are not dedicated to any single one and must balance their time and effort between all of these.
