It is common for a legal system to allow a person, in certain circumstances, to gain ownership of land by possessing it for a period of time. This is certainly true of both Scotland and England, although what is precisely required for possession to be established may differ on particular points between the two. One point on which the two may differ is the effect of a unilateral permission to occupy that is given to someone currently occupying the land without any right to be there. This point has most recently been considered from the point of view of English law in Smith v Molyneaux [2016] UKPC 35, [2017] 1 P & CR 7. In this paper, that case and the issues it raises are considered from the point of view of Scots law. It is found that this point raises more general questions about the nature of the mental element of possession, the state of mind with which one must occupy the property in order to be considered a possessor.
