(1) This section applies if—
(a) a unit is owned by 2 or more part-owners; and
(b) an amount is recoverable by the owners corporation from the owners.
(2) The part-owners are liable separately and together for the payment of the amount.
(3) As between themselves, each part-owner is liable for a part of the amount proportional to the value of the part-owner's interest in the unit.
(4) If a part-owner pays a part of the amount that is more than the part-owner's proportional liability, the part-owner may recover the excess from the other part-owners.
