A. If the declaration expressly so permits, a unit may be subdivided into two or more units. Subject to the provisions of the declaration and other provisions of law, upon application of a proprietary lessee to subdivide a unit, the association shall prepare, execute, and record an amendment to the declaration subdividing that unit. All costs for such preparation, execution, and recordation shall be borne by the proprietary lessees involved.
B. The amendment to the declaration must (i) be executed by the proprietary lessee of the unit to be subdivided, (ii) assign an identifying number to each unit created, and (iii) reallocate the allocated interests formerly allocated to the cooperative interest of which the subdivided unit is a part to the new cooperative interests in any reasonable manner prescribed by the proprietary lessee of the cooperative interest of which the subdivided unit is a part.
