Relocation of boundaries between adjoining units

(a) Subject to the provisions of the declaration and other provisions of law, the boundaries between adjoining units may be relocated by an amendment to the declaration upon application to the association by the owners of those units. If the owners of the adjoining units have specified a reallocation between their units of their allocated interests, the application must state the proposed reallocations. Unless the executive board determines, within thirty days, that the reallocations are unreasonable, the association shall prepare an amendment that identifies the units involved and states the reallocations. The amendment must be executed by those unit owners, contain words of conveyance between them, and, on recordation, be indexed in the name of the grantor and the grantee, and in the grantee's index in the name of the association. (b) The association (i) in a condominium or planned community shall prepare and record plats or plans necessary to show the altered boundaries between adjoining units and their dimensions and identifying numbers, and (ii) in a cooperative shall prepare and record amendments to the declaration, including any plans, necessary to show or describe the altered boundaries between adjoining units and their dimensions and identifying numbers.
