(1) The declaration shall allocate a fraction or percentage of undivided interests in the common elements and in the common expenses of the association, and a portion of the votes in the association, to each unit and state the formulas or methods used to establish those allocations. Those allocations may not discriminate in favor of units owned by the declarant or an affiliate of the declarant.

(2) If units may be added to or withdrawn from the condominium, the declaration shall state the formulas or methods to be used to reallocate the allocated interests among all units included in the condominium after the addition or withdrawal.

(3) The declaration may provide: (a) For cumulative voting only for the purpose of electing members of the board of directors; and (b) for class voting on specified issues affecting the class if necessary to protect valid interests of the class. A declarant may not utilize cumulative or class voting for the purpose of evading any limitation imposed on declarants by this chapter, nor may units constitute a class because they are owned by a declarant.

(4) Except for minor variations due to rounding, the sum of the undivided interests in the common elements and common expense liabilities allocated at any time to all the units must each equal one if stated as fractions or one hundred percent if stated as percentages. In the event of discrepancy between an allocated interest and the result derived from application of the pertinent formula, the allocated interest prevails.

(5) Except where permitted by other sections of this chapter, the common elements are not subject to partition, and any purported conveyance, encumbrance, judicial sale, or other voluntary or involuntary transfer of an undivided interest in the common elements made without the unit to which that interest is allocated is void.
