您好,在产权上我们一般把apartment 称为unit title, 属于很多人拥有common space
A unit title can be bought and sold, or leased or mortgaged. It is made up of three components:
Ownership in the particular units (which can be the apartment and the car park).
An undivided share in the ownership of the common property.
An undivided share in the ownership of the units if the unit plan is cancelled.
