A inium (or condo for short) is an ownership regime in which a building (or group of buildings) is divided into multiple units that are either each separately owned, or owned in common with exclusive rights of occupation by individual owners.
Inium is a Latin word that means "Owning property together." That's what it is like when someone buys a condo unit. They have an "interest" in the land beneath the building, but the building's association owns the actual land.
Ownership of a inium unit is evidenced by a inium certificate of title. With respect to real property other than land and inium units, there is no system that is equivalent to the Torrens system for registration under which a document is issued to evidence the owner's title.
