They must be separately occupied and enjoyed, as otherwise they will be part of the same dwelling (and section 115(2 would apply). 116 Subsection (3) defines common ownership for companies (subsection (3)(a)) as entitlement of the same or connected companies to the chargeable interests in each dwelling. Dwellings pass the common ownership test also if chargeable interests in each are held for the purposes of the same collective investment scheme (subsection (3)(b)). 117 Subsection (5) and (6) disapply subsection (4) if on the day in question either the main dwelling or the associated dwelling is relieved from the annual tax on enveloped dwellings or is a charitable company that is exempt from ATED because it is deemed not to meet the ownership condition. 118 Subsection (7) excludes public bodies or bodies established for national purposes from being connected companies. 119 Subsection (8) states that an interest held for the same collective investment scheme, includes an interest held by a person connected with the scheme. 120 Subsection (9) defines “separate access” for an associated dwelling as access direct from a road or on land over which the occupant has a right of way or other separate land interest. 121 Subsection (10) outlines the meaning of “garden or grounds”, “the person entitled to possession”, and “separately entitled” for the purpose of this section.
