The donation (CO art. 242/243) and exchange (CO art. 237/216) of real estate must be executed via notary in order to be valid, unlike in the case of estate distribution, where written form is sufficient (CCS art. 634).

Ownership by floor or condominium ownership is a particular form of co-ownership that also represents a real estate property. Its particularity lies in the fact that the co-owner has the exclusive power to administer, use, and improve some parts of the building that are considered private.
