: ''For the modern North American meaning as a type of housing, see
Condominium''
In
international law, a 'condominium' (plural either ''condominia'', as in Latin, or condominiums) is a political territory (state or border area) in or over which two or more sovereign powers formally agree to share equally ''dominium'' (in the sense of sovereignty) and exercise their rights jointly, without dividing it up into 'national' zones.
Although a condominium has always been recognized as a theoretical possibility, condominiums have been rare in practice. A major problem, and the reason why so few have existed in practice, is the difficulty of ensuring co-operation between the sovereign powers; once the understanding fails, the status is likely to become untenable.
The word is recorded in English since c.1714, from Modern Latin, apparently coined in Germany c.1700 from Latin ''com-'' "together" + ''dominum'' "right of ownership" (compare
domain).
Current condominia

Lake Constance (without islands) is considered by

The term is sometimes even applied to a similar arrangement between members of a Monarch's countries in (personal or formal) union, as was the case for the district of
Fiume (Rieka), shared between
Hungary and
Croatia within the Hapsburg Empire since 1868.
Co-principality
Under French law,
Andorra was once considered to be a French–
Spanish condominium, although it is more commonly classed as a
co-principality, since it is itself a sovereign state, not a possession of one or more foreign powers, even though the quality of Head of State is shared ex officio by two foreigners.
