Reasons for introducing 3D property in a legal system—Illustrated by the Swedish case
The use of three-dimensional (3D) property rights has for many years been a tool for providing secure and lasting rights for the use of land and its volume of space in complex situations involving land use in the urban society. The aim of this article is to investigate the reasons for introducing 3D property in a legal system. This is illustrated by using the Swedish system as an example. In general, without the possibility of forming 3D property units with direct ownership, other forms have to be used, such as indirect ownership or granted user rights.
