Accession (superficies solo cedit)
Legal concepts
Accession is the South African common-law principle that whatever is permanently attached to land becomes part of the land — captured in the maxim superficies solo cedit ("what is on the surface yields to the soil"). Fixtures pass automatically with the property at transfer; movables (fittings) do not. The principle is the legal basis for the fixtures-and-fittings test.
