  The details of property rights vary from jurisdiction to jurisdiction perhaps more than those of almost any other types of right. Further, many jurisdictions have different rules relating to property rights in land (and its fixtures) as opposed to all other types of entity. For these details reference should be made to specialist books in the jursdiction.  (Cf. Hume 1740, Book III, Section III, where he discusses the notions that, in his view, lie behind rules of occupation, prescription, accession and succession, by which property may be acquired. He points out that not infrequently one cannot sensibly claim that a rule of particular content is better than one of somewhat different content.  The important thing is, rather, that some legal rule on the matter exists.)
