Land is a vital commodity. So much so that a whole branch of the law has grown up around the subject and it even has its own central registry. It is nonetheless possible for land to be “lost”. A strip of land might be mistakenly left over after the sale of several plots with the owner not realising he has not disposed of it or a land owner might without his descendants (if he has any) knowing that he owned a particular piece of land. It was long since decided that land is too valuable to be allowed to go to waste and so the doctrine of adverse possession grew up to combat the risk.
