(b) Except as provided in (a) of this section, if part of a unit is acquired by eminent domain, the award must compensate the unit owner for the reduction in value of the unit and its interest in the common elements, whether or not any common elements are acquired. Upon acquisition, unless the decree provides otherwise,
- (1) the allocated interests of the unit are reduced either in proportion to the reduction in the size of the unit or on the basis specified in the declaration; and
- (2) the portion of the allocated interests divested from the partially acquired unit are automatically reallocated to the unit and to the remaining units in proportion to the respective allocated interests of the units before the taking, with the partially-acquired unit participating in the reallocation on the basis of its reduced allocated interests.
