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 Heaven and all the way to hell") or cuius est solum, eius est usque ad coelum et ad infernos (Latin for "whoever's is the soil, it is theirs all the way to Heaven and all the way to the depths below") is a principle of property law, stating that property holders have rights not only to the plot of land itself, but also to 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.
