Definition
A cap of maintenance is a ceremonial ornament of state — specifically, a cap of crimson velvet lined with ermine — forming part of the regalia of the sovereigns of England. It is carried before the monarch at coronations and other solemn state occasions, not worn in the ordinary sense, but borne as a symbol of royal dignity and sovereign honor. Caps of maintenance are also carried before the mayors of certain English cities as a mark of civic dignity and chartered privilege, the right to have the cap carried being a recognized honorific grant.
The term belongs to the vocabulary of English heraldry and constitutional ceremony. It does not describe a legal right, obligation, or remedy in the modern doctrinal sense, but it does carry legal significance insofar as the privilege of having a cap carried before a civic officer is a formal grant traceable to royal charter — and therefore a matter of record in the law of franchises and municipal privileges.

Common Language
Modern common usage (Wiktionary): A ceremonial cap of crimson velvet lined with ermine, worn or carried as a sign of nobility or special honour.
Historical common usage: The term does not appear in Webster's 1913 as a standalone entry, consistent with its status as a specialized term of English ceremony and heraldry rather than general vocabulary.
The common usage and legal usage are closely aligned here, but the legal sources add a dimension absent from the general definition: the carrying of a cap of maintenance before a mayor is not merely ceremonial custom — it reflects a specific legal grant of privilege. The distinction matters for researchers: the question is not what the cap looks like, but by what authority it is borne.

Why It Matters in Research
This term will appear almost exclusively in three research contexts: (1) historical treatments of English constitutional ceremony and the law of regalia; (2) heraldic law and the privileges of incorporated boroughs and municipalities; and (3) encyclopedic and dictionary sources of the nineteenth century that catalogued such terms as part of comprehensive coverage of English legal vocabulary.
Researchers working in American legal sources will rarely encounter this term in operative legal documents. Its presence in American legal dictionaries — including both editions of Black's — reflects the tradition of those works comprehensively covering English legal vocabulary, not any adoption of the concept into American law.
The principal research trap is the word "maintenance" itself. A researcher encountering this term in an index or keyword search may conflate it with the tort or criminal law concept of maintenance (the officious intermeddling in another's litigation), or with landlord-tenant law governing repair and upkeep obligations. These are entirely unrelated bodies of law. The "maintenance" in cap of maintenance derives from a different conceptual root — the sustaining or upholding of dignity and rank — and should not be read through a modern legal lens.
For researchers in English local government history or municipal charter law, the right to have a cap of maintenance carried before a mayor is a substantive privilege historically recorded in borough charters. Tracing whether a particular city held this right requires consulting the original charter grant, not general legal dictionaries.

Historical Dictionary Support
The three historical sources consulted — Black's (1st Ed.), Rapalje & Lawrence, and Black's (2nd Ed.) — are in complete agreement, reproducing nearly identical text drawn from the Encyclopaedia Londinensis. This uniformity signals that the compilers were working from the same secondary source rather than from independent legal analysis, which is typical for purely ceremonial or heraldic terms that entered legal dictionaries by way of comprehensiveness rather than doctrinal necessity.
None of the historical sources elaborates on the legal basis for the privilege of mayors carrying the cap, nor do they distinguish between the royal regalia use and the civic use in any analytical way. The gap is notable: the legal significance of the mayoral cap as a chartered privilege — potentially enforceable or contestable as a matter of franchise law — goes unaddressed. Researchers should not treat the dictionary entries as exhaustive on the legal dimensions of civic heraldic privilege.

Jurisdictional Note
Cap of maintenance is a concept grounded entirely in English law and ceremony. It has no recognized application in American, Scottish, or other common law jurisdictions outside England and Wales. Its appearance in American legal dictionaries is encyclopedic rather than operative.
