(1) The owner of each apartment may create any encumbrance, only against the apartment owned by him by executing an instrument and registering it in the office of the registering authority and the percentage of the undivided interest in the common areas and facilities appurtenant to such apartment in the same manner and to the same extent as may be created in relation to any other separate parcel of property subject to individual ownership:
Provided that where any such encumbrance is created, the apartment in relation to which such encumbrance has been created shall not be partitioned or sub-divided.
(2) In the event of a charge or any encumbrance against two or more apartments becoming effective, the apartment owners of the separate apartments may remove their apartments and the percentage of the undivided interest in the common areas and facilities appurtenant to such apartments from the charge or encumbrance on payment of the fractional or proportional amounts attributable to each of the apartments affected and on such payment, the apartment and the percentage of undivided interest in the common areas and facilities appurtenant thereto shall be free of the charge or encumbrance so removed.
Provided that such partial payment shall not prevent the person having a charge or any of the encumbrance from proceeding to enforce the rights, in relation to the amount not so paid, against any other apartment and the percentage of undivided interest in the common areas and facilities appurtenant to such apartment.
