(a) General rule.--If the declaration expressly so permits, a unit may be subdivided into two or more units or, in the case of a unit owned by a declarant, may be subdivided or converted into two or more units, common elements, or a combination of units and common elements. Subject to the provisions of the declaration and other provisions of law, upon application of a unit owner to subdivide a unit or upon application of a declarant to convert a unit the association shall prepare, execute and record an amendment to the declaration, including the plats and plans, subdividing or converting that unit.

(b) Execution and contents of amendment.--The amendment to the declaration must be executed by the owner of the unit to be subdivided, assign an identifying number to each unit created and reallocate the common element interest, votes in the association and common expense liability formerly allocated to the subdivided unit to the new units in any reasonable manner prescribed by the owner of the subdivided unit.

(c) Conversion of unit of declarant to common elements.--In the case of a unit owned by a declarant, if a declarant converts all of a unit to common elements, the amendment to the declaration must reallocate among the other units the common element interest, votes in the association and common expense liability formerly allocated to the converted unit on a pro rata basis, inter se.
