Cuius est solum, eius est usque ad coelum et ad inferos

Cuius est solum, eius est usque ad coelum et ad inferos (Latin for "whoever's is the soil, it is theirs all the way to the sky and to the depths") is a principle of property law, stating that property holders have rights not only to the plot of land itself, but also the air above and (in the broader formulation) the ground below. The principle is often referred to in its abbreviated form as the ad coelum doctrine.
