Definition
Averia caruce (also rendered averia carucae) is a Latin legal term from old English law meaning "beasts of the plough" — the draught animals, such as oxen and horses, used to draw a plough. At common law, these animals enjoyed a recognized privilege over other cattle, most notably an exemption from distraint for certain purposes. The term distinguished working plough animals from averia otiosa, meaning idle or unworked beasts, which carried no such privilege.
Why It Matters in Research
This term belongs to a cluster of medieval agrarian legal concepts that appear in early common law sources and are nearly absent from modern law. Researchers encountering averia caruce in historical documents should be alert to several things.
First, the privilege attached to plough beasts was a substantive legal protection with procedural consequences: these animals could not ordinarily be taken by distraint so long as other goods sufficient to satisfy the claim were available. Understanding this requires familiarity with the law of distress as it stood in the medieval and early modern periods, which differs substantially from modern landlord-tenant and debt-collection frameworks.
Second, the term appears in a Latin form tied to medieval agricultural organization — the caruca (plough) being the unit around which much of the feudal land assessment system was built. Researchers moving between averia caruce and related agrarian terms like carucate or carucage will find the connections substantive, not merely linguistic.
Third, the term surfaces primarily in early institutional sources — Fleta, Coke's Littleton, and Blackstone's Commentaries — rather than in reported cases. Researchers should not expect to find the term in standard case reporters; its natural habitat is the treatise literature and the Registrum Brevium (Register of Writs).
Fourth, because the privilege of plough beasts was rooted in the agricultural economy of medieval England, it has no surviving counterpart in modern law. Any modern research that encounters this term is almost certainly dealing with a historical question — title, tenure, or a document of antiquity — rather than a live legal issue.
Historical Dictionary Support
Burrill's Law Dictionary is the primary shelf source for this term and handles it accurately. Burrill identifies averia caruce as a term of old English law, glosses it in both Latin and Law French (bestes des charues), notes the common law privilege over other cattle, and distinguishes it from averia otiosa by reference to Fleta. The citations Burrill provides — Fleta lib. 2 c. 48, Coke on Littleton 85b, Blackstone's Commentaries 3:9, and the Registrum Originale 97b — are the authoritative primary sources for this concept and represent the full range of institutional support the term commands.
Fleta, the late thirteenth-century legal treatise, uses the variant bestia carucae and draws the explicit contrast with idle beasts (averia otiosa) that Burrill notes. Coke's treatment in the Littleton commentary confirms the privilege in the context of distress. Blackstone's brief reference in the third volume situates it within the broader law of personal property remedies.
What historical dictionaries collectively do not provide is any account of how and when this privilege faded from practical use. The concept is present in the sources through the early modern period but disappears from active legal discourse as agricultural tenures and distress practices were reformed by statute. No shelf source traces that extinction, leaving a gap that researchers must bridge through primary legislative and treatise sources.
Jurisdictional Note
Averia caruce is exclusively a term of old English common law with no recognized counterpart in American, Scottish, or other common law jurisdictions. Its relevance outside England is limited to historical research into documents or legal instruments that incorporate English common law principles by reception.
