Definition
De monte canisio (Latin: "of Dog's Hill" or "of Montchensey") is an archaic Latin phrase appearing in early English common law sources, particularly in Bracton's De Legibus et Consuetudinibus Angliae. The phrase functions as a proper name reference — specifically to the Montchensey family or their associated lands — rather than as a term of general legal art. In the contexts where it appears in Bracton, it is cited in connection with illustrative examples or authoritative precedents drawn from actual cases or land disputes involving that family.
The Latinized form "de monte canisio" is a direct rendering of the Norman-French surname Montchensey (from mont, "hill," and chien/canis, "dog"), a notable baronial family in medieval England.
Why It Matters in Research
This term will appear in researchers working through Bracton's treatise in its original Latin, where the Montchensey references occur at folios 87b, 391, and 407b. The phrase is not a legal doctrine or writ in its own right — it is a proper name embedded in Latin legal prose, and misreading it as a term of art would be a significant interpretive error.
Researchers consulting Burrill should note that his entry is unusually spare, offering only the anglicized surname and the three folio citations. This reflects the nature of the term: Burrill includes it as a finding aid for readers who might encounter the Latin form in Bracton and need to identify it, not as a substantive legal definition.
The primary trap in historical sources is treating every Latin phrase in a medieval treatise as a standalone legal concept. De monte canisio is a locative surname — a person identified by their place of origin or landholding — which was the standard naming convention in Norman and early Plantagenet England. Readers unfamiliar with this convention may search fruitlessly for a writ, doctrine, or legal category by this name.
The Bracton folios where this name appears deal with real property, seisin, and the forms of action relevant to land recovery, which provides navigational context: if you are encountering this phrase, you are likely working in a section of Bracton addressing those subjects, and the Montchensey reference is being used as an illustrative precedent or example case drawn from the author's experience or knowledge of actual disputes.
Historical Dictionary Support
Burrill's Law Dictionary is the only shelf source in the Law Mind corpus to include this entry, and the entry itself is essentially a cross-reference: it gives the anglicized form of the name and directs the reader to three specific folios in Bracton. No definition of legal content is offered because none is warranted — the entry exists purely as a transliteration and locator.
This type of entry is characteristic of Burrill's broader approach to Latin and Norman-French terms encountered in Year Books and early treatises: he catalogs them as vocabulary items researchers will meet in the wild, even when they carry no independent doctrinal weight. Researchers using later dictionaries (Bouvier, Black's) will find no corresponding entry, which itself confirms that the term never entered the general common law lexicon as a legal term of art.
Jurisdictional Note
Relevant only to English common law in its medieval and early modern period. No application in American law, and no equivalent appears in civilian or canon law traditions.
