Property ownership to the sky and depths: modern limits confine airspace rights while preserving subterranean ownership. The maxim cujus est solum, ejus est usque ad coelum et ad inferos presumes vertical ownership of land, but modern law limits airspace rights to heights necessary for ordinary use while maintaining a presumption of subterranean ownership of minerals; owners may sever or dispose of airspace or subsoil rights and, absent contrary intention, grants pass the grantor's full interest in those vertical rights.
