Definition
A coat of mail or suit of armor. In feudal law, the term refers to a hauberk — the chain-mail garment worn by knights — and serves as the defining marker of a particular class of military tenure. A tenant holding by *servitium hauberticum* (haubert service) owed knight service to a lord in exchange for a fief, with the haubert symbolizing the equipment obligation at the heart of that relationship. The term appears primarily in Norman French legal sources and is encountered almost exclusively in early English feudal land law.
Common Language
Modern common usage (Wiktionary): A surname.
Historical common usage (Webster's 1913): Not entered as a common English word; the armor sense (*hauberk*) appears separately as a distinct headword.
The common language gap here is one of obscurity rather than divergence. Most modern readers will encounter *haubert* only as a surname or not at all. In legal sources, the word carries specific technical weight: it identifies not merely a piece of equipment but an entire category of tenure — the fief d'haubert — with defined obligations and legal consequences for inheritance, wardship, and service. Treating it as merely a costume reference in historical records will cause a researcher to miss its doctrinal significance entirely.
Why It Matters in Research
Researchers working in early English land law, feudal tenure, or Norman legal sources will encounter *haubert* primarily in two contexts: the physical object (coat of mail) as a marker of knight status, and *servitium hauberticum* as a shorthand for the full bundle of military tenure obligations.
The critical navigational point is the connection to **fief d'haubert**. When Burrill cross-references that entry, he is pointing toward the substantive doctrine — the class of feudal holding defined by knight service rendered in haubert armor. Researchers should follow that cross-reference immediately; the standalone *haubert* entry is essentially a gateway term.
Trap in historical sources: Norman French feudal terminology was inconsistently anglicized across early English Year Books and treatises. *Haubert*, *hauberk*, *haubergeon*, and related spellings appear interchangeably in different sources. Coke's *Littleton* (Co. Litt. 108a, the authority Burrill cites) is the standard reference point for how English common law absorbed this term, and researchers should anchor there before moving to Year Book sources.
Jurisdictional relevance: This term belongs almost entirely to English feudal land law as transmitted through Norman custom. It has no operative meaning in American law, though it may appear in historical title chains or in academic treatments of the feudal background to common law tenures.
Historical Dictionary Support
Burrill's Law Dictionary is the only shelf source with a dedicated entry. Burrill defines *haubert* concisely as a coat of mail or haubergeon, cites Co. Litt. 108a and Spelman's *Glossarium* as primary authorities, and notes *servitium hauberticum* (military service) with additional reference to Wright on Tenures. The entry is brief by design — Burrill treats *haubert* as a lexical signpost pointing toward *fief d'haubert*, where the substantive legal content lives.
What historical sources miss: No extended doctrinal analysis appears under this headword in any standard legal dictionary. Researchers seeking the full picture of haubert tenure — its obligations, its place in the hierarchy of feudal holdings, wardship incidents, and the process by which these tenures were abolished — must consult treatises on English feudal tenure directly. Blackstone's *Commentaries*, Book II, and Wright's *Law of Tenures* provide the fuller context that dictionary entries presuppose.
Jurisdictional Note
Operative only in historical English feudal law. Haubert tenure and its associated obligations were effectively abolished along with military tenures generally by the Tenures Abolition Act 1660. The term has no current legal force in any common law jurisdiction but remains relevant for title historians and legal historians working with pre-1660 English land records.
