Definition
Averia (also rendered averia carrucae) is an old English legal term for working cattle — specifically draft animals such as horses, oxen, and mules kept and used for agricultural labor. The term appears in medieval property and tenancy records where the status, ownership, and distress of such animals had legal significance. Working cattle occupied a distinct category in early English law because of their productive function: they were both property and instruments of subsistence farming, which affected the rules governing their seizure under distress.
AVERIA CARRUCAE refers specifically to beasts of the plow — the draft animals attached to a plowteam. This subset of averia enjoyed particular protection under early English law, as distraining a tenant's plow animals could destroy the capacity to farm and thus the ability to pay rent at all.
Recognized Forms
/SUBTYPES
Averia (general): All working cattle, including horses, oxen, and mules used for farm labor.
Averia Carrucae: Beasts of the plow specifically; the plowteam animals. This subtype carried distinct legal protections against distraint in early common law.
Why It Matters in Research
Researchers encounter averia most often in the context of distress and distraint — the common law remedy allowing a landlord or lord to seize a tenant's goods for non-payment of rent or services. The rules surrounding what could and could not be distrained were complex, and working cattle, especially averia carrucae, were historically privileged from distress because seizing the plow animals would render the tenant incapable of farming and therefore incapable of satisfying any future obligation. Understanding this term is essential for interpreting medieval pleading records, manorial court rolls, and early common law treatises that discuss what property was exempt from seizure.
The term also surfaces in historical discussions of feudal tenure and the obligations attached to villeinage. Tenants holding land in villein tenure often owed labor services (including plowing services with their own animals), making the status of averia directly relevant to the nature of the tenure itself.
Researchers using older abridgments, Year Books, or Bracton-era materials should watch for variant spellings and Latinized forms. The term does not appear in modern statutory or case law; its relevance is purely historical and confined to medieval and early modern English legal sources.
Historical Dictionary Support
The four source dictionaries are substantially in agreement on the core meaning: working cattle, specifically horses, oxen, and mules. There is no meaningful divergence on substance.
Burrill's Law Dictionary is the most analytically useful of the four, tracing the Law French root (avers, from ouvre or ouvrage, meaning work or labor) and citing Spelman's Glossarium Archaeologicum — a standard authority for medieval legal Latin and Law French terms. This etymology anchors the legal meaning firmly in the idea of labor-producing animals, distinguishing averia from cattle held purely as stock or for consumption.
Black's (both editions) and Rapalje & Lawrence provide only surface-level definitions, noting the working-cattle meaning without elaboration on the legal rules attaching to the term. None of the four dictionaries discusses the distress exemption for averia carrucae in depth, which is the context where the term most frequently matters to a legal historian. Researchers needing fuller treatment should consult Spelman directly, or Coke's commentaries on distress, where the privileges of plow beasts are examined.
Jurisdictional Note
Averia is a term of old English law with no counterpart in American legal usage. It has no application in any modern common law jurisdiction as operative law. Its relevance is exclusively historical, confined to English medieval and early modern sources.
