  Secondly, it should be noted that, in law, property rights can be of many different types. Although ownership is obviously one of the most important, another major class is that of possession, whether temporary or relatively permanent. For example, the right to use a car which one has hired for a week or to live in a certain house for the rest of one’s life. Yet other types, falling short of either ownership or possession, could be, for example, to walk across the local farmer’s field or have one’s next-door neighbour maintain his side of the joint garden wall.
