(1) If a unit is acquired by eminent domain or part of a unit is acquired by eminent domain leaving the unit owner with a remnant which may not practically or lawfully be used for any purpose permitted by the declaration, the award must include compensation to the unit owner for that unit and its allocated interests whether or not any common elements are acquired. Upon acquisition, unless the decree otherwise provides, that unit's allocated interests are automatically reallocated to the remaining units in proportion to the respective allocated interests of those units before the taking. Any remnant of a unit remaining after part of a unit is taken under this subsection (1) is thereafter a common element.

(2) Except as provided in subsection (1) 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 otherwise provides:

(a) That unit's allocated interests are reduced in proportion to the reduction in the size of the unit or on any other basis specified in the declaration; and

(b) The portion of allocated interests divested from the partially acquired unit is automatically reallocated to that unit and to the remaining units in proportion to the respective interests of those units before the taking, with the partially acquired unit participating in the reallocation on the basis of its reduced allocated interests.

(3) If part of the common elements is acquired by eminent domain, that portion of any award attributable to the common elements taken must be paid to the association. Unless the declaration provides otherwise, any portion of the award attributable to the acquisition of a limited common element must be equally divided among the owners of the units to which that limited common element was allocated at the time of acquisition. For the purposes of acquisition of a part of the common elements other than the limited common elements under this subsection (3), service of process on the association shall constitute sufficient notice to all unit owners, and service of process on each individual unit owner shall not be necessary.

(4) The court decree shall be recorded in every county in which any portion of the common interest community is located.

(5) The reallocations of allocated interests pursuant to this section shall be confirmed by an amendment to the declaration prepared, executed, and recorded by the association.
