The territory belonging to a tribe is divided among its members. Each family has the exclusive right by inheritance to a part of the tribal lands, which is named after its owner; and his family and every child born on it must be named after something on the property. When the boundaries with neighbours meet at lakes or swamps celebrated for game, well-defined portions of these are marked out and any poaching or trespassing is severely punished. No individual of any neighbouring tribe or family can hunt or walk over the property of another without permission from the head of the family owning the land. A stranger found trespassing can legally be put to death.

When the father of a family dies, his landed property is divided equally among his widow and his children of both sexes. Should a child of another family have been born on the estate, it is looked upon as one of the family, and it has an equal right with them to a share of the land, if it has attained the age of six months at the death of the proprietor. This adopted child is called a ‘woork’, and calls the owner of the property by the same name. Should a family die out without leaving ‘flesh relatives’ of any degree, the chief divides the land among the contiguous families after the lapse of one year from the death of the last survivor. During that period the name of the property, being the same as the name of its last owner, is never mentioned, but is called ‘Yaamp yaamp’ in the Ohaap wuurong and the other two languages.
