Legal act by which a syndicate of co-owners obtains the ownership of an immovable (e.g. land or the janitor’s apartment) or obtains rights upon an immovable (e.g. a servitude on the land adjacent to the co-ownership). This deed is usually signed before a notary. The general meeting of co-owners must approve an acquisition of immovables by the syndicate of co-owners, by a enhanced majority.
