Reconstruction of the history of the right of ownership of an immovable by examining, in chronological order (ascending or descending), the property titles appearing in the Québec Land Register and covering a period of 30 or 51 years and sometimes even covering a period beginning with the depositing of the cadastre. The preparation of this chain of titles will therefore list the titles (sales, transfers, declarations of transfer of immovable property, etc.) for this period in order to determine the owner of the immovable on a given date.
