(1) The declaration must allocate to each unit:

(a) In a condominium, 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;

(b) In a cooperative, an ownership interest in the association, a fraction or percentage of the common expenses of the association, and a portion of the votes in the association; and

(c) In a plat community and miscellaneous community, a fraction or percentage of the common expenses of the association and a portion of the votes in the association.

(2) The declaration must state the formulas used to establish allocations of interests. Those allocations may not discriminate in favor of units owned by the declarant or an affiliate of the declarant.

(3) If units may be added to or withdrawn from the common interest community, the declaration must state the formulas to be used to reallocate the allocated interests among all units included in the common interest community after the addition or withdrawal.

(4)(a) The declaration may provide:

(i) That different allocations of votes are made to the units on particular matters specified in the declaration;

(ii) For cumulative voting only for the purpose of electing board members; and

(iii) For class voting on specified issues affecting the class if necessary to protect valid interests of the class.

(b) A declarant may not utilize cumulative or class voting for the purpose of evading any limitation imposed on declarants under this chapter, and units do not constitute a class because they are owned by a declarant.

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

(6)(a) In a condominium, 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.

(b) In a cooperative, any purported conveyance, encumbrance, judicial sale, or other voluntary or involuntary transfer of an ownership interest in the association made without the possessory interest in the unit to which that interest is related is void.
