A co-ownership comprising private portions and common portions situated one beside another (for example, townhouses). This type of co-ownership is the least used type of co-ownership.
By purchasing a condo (apartment) in a residential tower, you automatically become an owner in a vertical co-ownership. You can also be in a divided co-ownership, if you purchase a house (semi-detached or townhouse), built on the same lot than other individual homes. It is then called a horizontal co-ownership.
