Definition
In law, CREST refers to a heraldic device borne above the shield and helmet in a coat of arms. It is the ornamental figure or charge that surmounts the helm in a full armorial achievement, distinct from the shield bearings themselves. The crest identifies the bearer's family or rank and, together with the shield, motto, and supporters, constitutes a complete heraldic achievement. In legal contexts, crests appear most often in disputes over armorial rights, the registration of trademarks and corporate insignia derived from family arms, grants of arms by heraldic authority, and probate or succession matters involving heritable honors.
Common Language
Modern common usage (Wiktionary): The summit of a hill or mountain ridge; a tuft or natural ornament on an animal's head (the comb of a cockerel, the swelling of a snake's head, the raised feathers of a bird); the plume or decorative device worn on or displayed on a helmet.
Historical common usage (Webster's 1913): A tuft or excrescence growing on an animal's head, as the comb of a cock or the swelling on the head of a serpent; also the plume of feathers or other decoration worn on a helmet, indicating the rank of the wearer.
The everyday senses of the word — an animal's natural crown or a hilltop — share the same visual root as the heraldic meaning, but only the heraldic sense carries legal weight. A casual reader encountering "crest" in older legal documents may conflate it with the full coat of arms or treat it as a synonym for the shield itself. In strict heraldic and legal usage, the crest is one discrete component of an armorial achievement, not the whole.
Common Confusion
CREST vs. COAT OF ARMS: The crest is a single element of a full armorial achievement. Popular usage treats "crest" and "coat of arms" as interchangeable; legal and heraldic usage does not. A family may bear arms without a formal crest, and granting or disputing one component does not automatically affect the others.
CREST vs. DEVICE or BADGE: A heraldic badge or device may be derived from armorial bearings and used for identification, but it is not the same as a crest, which occupies a defined structural position atop the helm within the achievement.
Why It Matters in Research
Researchers encounter CREST most often in three contexts within the Law Mind corpus: heraldic law and grants of arms, intellectual property (particularly trademark registrations for businesses or institutions using armorial imagery), and succession law involving heritable dignities and the property rights associated with armorial bearings.
The critical navigational trap is terminological slippage. Pre-twentieth-century legal documents — wills, grants, royal patents, and pleadings in armorial disputes — frequently use "crest" loosely to mean the entire heraldic achievement. When a nineteenth-century testator bequeaths the "family crest," the instrument may intend to pass the full arms, not the crest alone. Read surrounding context and any described visual elements carefully before concluding what was legally intended to transfer.
In English law, the right to bear arms, including a crest, is a form of incorporeal property regulated by the College of Arms (for England, Wales, and Northern Ireland) and the Court of the Lord Lyon (for Scotland). Disputes over armorial rights have produced a distinct body of legal authority that intersects with both property law and the law of dignities. Researchers following a chain of title to arms must track grants and confirmations through heraldic registers, not merely through general property records.
For trademark and corporate identity work, researchers should note that armorial bearings — including crests — can be registered as trademarks, and claims of prior heraldic right have occasionally been raised in opposition proceedings. The overlap between heraldic authority and intellectual property law is an area where sources from different legal traditions may not map cleanly onto one another.
Jurisdictional variation matters here more than in most areas: Scottish armorial law, administered by the Lord Lyon King of Arms, is more strictly enforced and more litigation-ready than its English counterpart. A researcher working on Scottish materials will find a richer body of decided cases and statutory authority than comparable English sources provide.
Historical Dictionary Support
Both editions of Black's Law Dictionary define crest identically and minimally: a term used in heraldry signifying the devices set over a coat of arms. This is accurate but thin. Neither edition situates the term within the structure of a full armorial achievement, explains the distinction from shield bearings, or addresses the legal contexts — succession, grants, disputes — in which the term most often appears in practice.
Webster's 1913 and Wiktionary are more descriptive about the visual and natural-history senses, confirming that the helmet-ornament meaning is the bridge between everyday and legal usage. Neither dictionary source addresses the legal significance of the crest as heritable property or as a subject of armorial grants.
The historical dictionaries do not address trademark implications or the Scottish/English jurisdictional divide — both of which are essential for any serious legal research involving armorial bearings in modern sources.
Jurisdictional Note
In Scotland, the Lord Lyon King of Arms exercises statutory and criminal jurisdiction over armorial matters; unlawful use of arms, including crests, can be prosecuted. In England and Wales, the College of Arms grants and records arms but enforcement is civil and less frequently pursued. Researchers working on Irish heraldic questions must consult the Office of the Chief Herald of Ireland, which operates under a separate authority from either British body.
