A testamentary devise of part of a lot does not constitute a 'subdivision' within s 135(1)(a) of the Planning and Development Act 2005 (WA) and is not void for illegality. The word 'subdivide' in s 135(1)(a) means to make or lodge an application to create new lots with separate certificates of title; it does not encompass dealings in land such as testamentary dispositions, leases, licences or sales — those are regulated by s 136. The earlier decisions in Palamore, Riverwest and Bakranich, which held that testamentary devises of parts of unsubdivided lots were void, are no longer good law. Solicitors drafting wills may devise portions of a single lot to different beneficiaries; the executor/trustee will need to obtain subdivision approval to transfer legal title, but the equitable interests are valid.
