Definition
A cessor is a person who ceases or neglects to perform a duty or service owed under law or tenure for so long a period that he incurs legal jeopardy — specifically, liability to have a writ of cessavit brought against him. The term belongs to the vocabulary of old English land law and has no meaningful application in modern practice.
In its operative context, a cessor was typically a tenant who held land by a form of feudal service and who, having failed to render that service for a legally significant period (commonly two years), exposed himself to forfeiture or recovery of the land by the lord through the cessavit process. The term describes not merely a temporary default but a sustained, actionable neglect that ripened into legal consequence.

Common Language
Modern common usage (Wiktionary): One who is dilatory, negligent, and delinquent in duty or service, thereby incurring legal danger and liability to the writ of cessavit.
Historical common usage (Webster's 1913): One who neglects, for two years, to perform the service by which he holds lands, so that he incurs the danger of the writ of cessavit.
The common and legal definitions align unusually closely here because the term never entered general English usage outside of its legal context. Webster's 1913 includes the two-year threshold — a procedurally specific detail that the legal dictionaries state more abstractly. Researchers should treat Webster's entry as substantively legal, not merely linguistic.

Common Confusion
CESSOR should not be confused with CESSION, which refers to the voluntary transfer or relinquishment of territory, rights, or property. The two words share a Latin root (cedere, to yield or give way) but name entirely different concepts. CESSOR describes a status — a person who has neglected a duty — while CESSION describes an act of transfer. Confusion is most likely in older handwritten records or abbreviated legal notes where "cess-" prefixes appear without full context.

Why It Matters in Research
CESSOR is an obsolete term of art, but it surfaces in English legal history sources and in any research touching feudal tenure, copyhold, or the cessavit writ. Researchers should be alert to several navigational points:
First, the term is definitionally dependent on its procedural companion. CESSOR means very little without an understanding of the writ of CESSAVIT, which was the legal mechanism triggered by a cessor's neglect. Any source discussing one will typically require the other for full comprehension.
Second, the two-year threshold noted in Webster's 1913 and in Cowell's legal glossary is a procedural detail not always foregrounded in the law dictionary definitions. When reading historical sources — particularly Year Books, abridgments, or treatises on copyhold — the specific duration of neglect may be legally operative, not merely descriptive.
Third, the abbreviation "O.N.B." cited in both editions of Black's refers to the Old Natura Brevium, a foundational English treatise on writs. Researchers encountering this citation in historical legal dictionaries should recognize it as a primary source on writ practice, not a secondary authority. Black's cites folio 136 in connection with this term.
Fourth, because CESSOR describes a status under feudal tenure law, it will appear most frequently in pre-1700 English sources — Year Books, abridgments, and treatises on land law. It does not appear in American legal sources as a live term and is absent from modern statutory or case law.

Historical Dictionary Support
The four source dictionaries are in substantive agreement, with minor differences in framing. Black's (both editions) and Bouvier's define cessor as one who neglects or ceases to perform a duty "so long" as to incur legal danger — a threshold-based formulation that leaves the duration implicit. Bouvier's is the most complete, explicitly connecting the term to liability under the writ of cessavit, which is the procedural consequence that gives the status its legal significance.
Burrill's entry is fragmentary as preserved, cutting off mid-definition, but confirms the core meaning and the old English law context.
Webster's 1913 and Wiktionary, unusual among common-language sources, add procedural specificity: the two-year period. This detail traces to John Cowell's Interpreter (1607), a legal-linguistic glossary that Webster's cites directly. Researchers should note that Cowell's work, while influential, reflects early seventeenth-century English law and may not capture earlier or later variation in how courts applied the cessavit process.
None of the historical dictionaries address what categories of service or tenure could give rise to the cessor status, nor do they discuss whether the doctrine varied by type of tenure (knight service versus socage versus copyhold). That silence reflects the term's narrow procedural function rather than any gap in the dictionaries' ambition.

Jurisdictional Note
CESSOR is a term of English law with no American legal application. The feudal tenure system that gave rise to the cessavit writ was not received as operative law in the American colonies or states, though the terminology appears in American legal dictionaries as historical record. Researchers working in English legal history should consult sources within the English common law tradition; the term is irrelevant to any American jurisdiction.
