Definition
Armorial bearings are the heraldic devices — emblems, symbols, and identifying marks — depicted on a coat of arms or (historically) on the shield of a person of noble or gentle rank. In English law, armorial bearings are the formal insignia granted by heraldic authority (the College of Arms in England) that identify an individual, family, or institution and serve as legal proof of gentle or noble status. The right to bear such arms is hereditary and, in English law, has historically been treated as a form of incorporeal property, transmissible by descent and capable of legal protection.
The term is used both in the singular (an armorial bearing, meaning a single heraldic element) and in the plural (armorial bearings, meaning the complete composition of a coat of arms). In legal contexts, the plural is standard and refers to the whole heraldic achievement as recognized by authority.
Common Language
Modern common usage (Wiktionary): Simply the plural of "armorial bearing" — a heraldic device associated with a person, family, or institution.
Historical common usage (Webster's 1913): Webster's treated "armorial" as an adjective meaning "belonging to armor or to the heraldry of arms," and "bearings" in a heraldic sense as the devices borne on a shield. The compound phrase carried the meaning of inherited heraldic insignia.
The gap between common and legal usage is narrow in form but significant in substance. In ordinary speech, armorial bearings evokes pageantry and decoration. In English law, the term carries enforceable legal weight: the unauthorized assumption of another's armorial bearings has historically been actionable, the right to bear specific arms is a matter of legal record and grant, and armorial bearings have been treated as heritable incorporeal property subject to legal succession rules entirely distinct from anything suggested by the decorative connotation.
Common Confusion
Armorial bearings should not be confused with the constitutional "right to bear arms" in the American legal tradition. The Second Amendment phrase refers to weapons — firearms — and operates within an entirely different legal framework. The similarity in language between "bearing arms" (constitutional) and "armorial bearings" (heraldic) is etymological coincidence, not legal connection. Researchers working in early English legal sources will encounter both usages and must read context carefully. The Latin maxim in Black's — noting that "arms" includes shields, swords, helmets, staves, and stones — reflects the broad Roman-law meaning of armorum, not the heraldic meaning that armorial bearings inhabits.
Why It Matters in Research
Researchers will encounter armorial bearings most often in three contexts: English common law materials on incorporeal hereditaments (heraldic rights as a species of property), taxation and revenue law (armorial bearings were subject to a stamp duty in England from 1793 onward, making the term appear in fiscal statutes and case law unrelated to heraldry proper), and historical biographical or genealogical records where the grant or right to armorial bearings established or evidenced social and legal status.
The stamp duty context is a significant trap. Late eighteenth- and nineteenth-century English statutes imposed a tax on the use of armorial bearings on carriages, seals, plate, and other items. Case law arising from that tax appears in law reports under subject headings that may surprise researchers expecting heraldic or property law. A researcher scanning English revenue cases may encounter armorial bearings as a fiscal category entirely divorced from questions of noble rank or heraldic title.
The historical definitions in Black's — both editions — are incomplete and cut off mid-text. The Latin maxim quoted in both editions (Armorum appellatione...) is drawn from Roman law sources and signals that the early editors were reaching to Roman foundations to explain a concept that is, in practice, entirely a creature of English heraldic law and the jurisdiction of the College of Arms. Researchers should not rely on Black's alone for the legal incidents of armorial bearings; English heraldic law requires specialist sources.
Jurisdictional variation is critical here. Armorial bearings as a legal category is substantially an English (and by extension, Scottish — with important differences) concept. American law has no heraldic authority and no legal framework for recognizing or enforcing armorial rights. State trademark or unfair competition law may incidentally protect heraldic symbols, but that is not armorial bearings law. Canadian and Australian law carries English heraldic traditions through their own heraldic authorities. Researchers working across jurisdictions must not import English heraldic legal concepts into American legal analysis.
Historical Dictionary Support
Both editions of Black's Law Dictionary offer essentially the same definition, and both are truncated — the entries end mid-sentence in the surviving digitized text, which is a known artifact of the source material rather than an editorial choice. What survives establishes two propositions: first, that armorial bearings are the criterion of noble and gentle rank in English law; and second, that the Roman-law concept of arma was broad (encompassing staves and stones alongside traditional weapons), which the editors cite to explain the expansive historical meaning of the term "arms."
Neither edition addresses the fiscal and revenue law dimension of armorial bearings — a significant omission given how frequently the term appears in that context in nineteenth-century English legal materials. Neither edition addresses the College of Arms, the legal process of granting or confirming arms, or the rules governing transmission of armorial bearings by descent (including the different rules for English and Scottish heraldry). Historical dictionary sources are therefore useful only as an entry point; they do not equip a researcher to work confidently with armorial bearings as a legal concept.
Jurisdictional Note
Armorial bearings as a legally operative category belongs to English and Scottish law, with parallel institutions in Ireland, Canada, and other Commonwealth jurisdictions. The United States has no heraldic authority and no body of armorial bearings law. Researchers working in pre-Revolutionary American colonial records may encounter armorial bearings in the English legal sense; post-Revolution, the term in American sources is either historical reference or decorative usage without legal force.
