Professor Mee made the point that joint tenancy is a specific and particular form of property ownership, which I understand. In respect of all other properties it is difficult to establish how they might be split or what claim the estate of the deceased or the murderer might have on them? In the case of the main property held in joint tenancy, potentially the deceased would have come to benefit from the entirety of the property, which is relatively clear. Is it in any sense arguable that it is not arbitrary because we have an understanding of what might otherwise have happened with that property?
