Definition
A purchaser at a judicial sale — most commonly a sheriff's sale — in Canadian law. The term denotes the party to whom property is knocked down or awarded at a forced sale conducted under court authority or by an officer of the court. The concept is drawn from French civil law and reflects the civilian tradition embedded in Quebec's legal system, where judicial sales of property follow procedures distinct from those in common law provinces.
Why It Matters in Research
This is a term of art encountered almost exclusively in historical Canadian legal materials, particularly those originating from Quebec or from courts operating under the influence of French civil law. Researchers consulting 19th-century Lower Canada reports — the primary sources cited across all shelf dictionaries — should understand that the adjudicataire occupies a specific procedural role: the successful bidder at a sale conducted judicially, whose title derives from the court's authority rather than from a voluntary conveyance by the original owner.
The term surfaces in questions of title, priority of claims, and the effect of the sale on pre-existing encumbrances. A researcher tracing property title through Quebec records or Lower Canada judgments will encounter this term in contexts where the English equivalent "purchaser at sheriff's sale" would appear in common law jurisdictions. The distinction matters because the rights and obligations attached to the adjudicataire under the civilian tradition — including questions of what encumbrances survive the sale — may differ from the common law treatment of a sheriff's sale purchaser.
Because the term is French in origin and predominantly found in bilingual or French-language Lower Canada reports, English-language secondary sources may gloss over procedural nuances that are visible only in the original French-language decisions. Researchers should not assume that the English phrase "purchaser at a judicial sale" is a perfect functional equivalent in every context; the civilian framework governing the process of adjudication (the sale itself) shapes what the adjudicataire acquires and what obligations follow.
Note also the Rapalje & Lawrence entry, which appears to conflate two separate definitions — the adjudicataire definition is followed mid-entry by material on average adjustment that belongs to a different term entirely. This is a transcription or typesetting artifact in that source and should not be read as a connected legal concept.
Historical Dictionary Support
All four shelf sources agree on the core definition: a purchaser at a sheriff's or judicial sale in Canadian (specifically Lower Canada/Quebec) law. Black's (both editions) and Bouvier's track each other closely, citing the same Lower Canada reports — 1 Low. Can. 241 and 10 Low. Can. 325 — as authority. Rapalje & Lawrence adds the useful clarification that the term designates the purchaser specifically at a "judicial sale," which is slightly broader than a sheriff's sale and better captures the civilian usage, where the sale is an act of the court rather than solely of the sheriff as enforcement officer.
None of the historical sources explain the procedural mechanism by which one becomes an adjudicataire, the effect of the adjudication on title, or how the role functions within Quebec's civil law framework. For that depth, researchers must go beyond the dictionaries to the Lower Canada civil procedure materials and, after 1866, the Civil Code of Lower Canada and its successors.
Jurisdictional Note
The term is specific to Canadian law and is primarily associated with Quebec's civil law tradition. In common law provinces, the functional counterpart is simply the purchaser at a sheriff's or execution sale, governed by entirely different procedural rules. Researchers should not expect to find this term in Ontario, British Columbia, or other common law provincial materials.
