Definition
A part or portion of a larger field or ground that would otherwise be held in gross or in common. In medieval land law, campartum described a distinct parcel carved out of a larger undivided holding — the share or division that an individual holds separately within what might otherwise be treated as a single unified estate or common land.
The term appears principally in old English records and pleadings. Its practical significance lies in its connection to champerty: the campartum was the divided share of land that a champertor would receive in exchange for financing litigation to recover or establish title to that land.
Common Confusion
Campartum and champerty are distinct but historically entangled concepts. Campartum is the thing — the parcel of land itself, the share or division. Champerty is the arrangement — the agreement by which a party finances another's lawsuit in exchange for a portion of the recovery, which in land disputes often took the form of that very parcel. Researchers encountering campartum in historical pleadings should not assume the document is about the tort of champerty; it may simply be describing a physical division of land. The connection between the two concepts is etymological and historical, not definitional.
Why It Matters in Research
This is an archaic Latin law term drawn from medieval English land practice. Researchers are unlikely to encounter it in any modern legal instrument. Its primary research relevance is threefold.
First, it appears in old English court records and land documents — particularly those involving disputed common fields, open-field agriculture, and the division of strips or parcels within larger agricultural holdings. Understanding campartum helps decode what a pleading is actually describing when it distinguishes one party's claim from an undivided common interest.
Second, the term serves as a gateway to champerty doctrine. Historical dictionary entries, including Burrill's, explicitly gloss campartum as champerty or as the share received under a champertous arrangement. A researcher tracing the historical development of champerty through primary sources may encounter campartum as shorthand for the land consideration at the heart of early champertous agreements.
Third, the term illustrates the instability of Latin law terms across editions and sources. The Black's entries (1st and 2nd editions) handle the definition cleanly but are disrupted in the source material by proximity to the Campbell's Acts entries — a reminder that early dictionary pagination and indexing can create apparent textual confusion when consulting physical volumes or imperfect digitizations. Burrill's adds the gloss connecting campartum to a judge's chamber, which appears to be a transcription artifact from a damaged or misread source; researchers should treat that gloss with caution.
Historical Dictionary Support
All four source dictionaries agree on the core definition: a part or portion of a larger field or ground that would otherwise be in gross or in common. The phrasing is nearly identical across Black's 1st and 2nd editions and Bouvier's, suggesting a shared lineage (likely Termes de la Ley or similar early glossaries). Bouvier's is alone in appending a direct cross-reference to champerty immediately after the definition, making the doctrinal connection explicit. Burrill's is the most informative but also the most problematic: it supplies a citation to Dyer 59b and 140b, which grounds the term in a recognized English law report, but it also introduces the anomalous gloss "a judge's chamber" — almost certainly a transcription error or binding artifact rather than a genuine secondary definition. No other source supports a chamber meaning, and Dyer's reports do not suggest it. Researchers relying on Burrill's should treat the definition as reliable and the chamber gloss as a copying artifact to be disregarded.
None of the historical dictionaries provide extended treatment. Campartum was already archaic by the time these dictionaries were compiled; the entries are brief because the term had long since passed out of active legal use.
Jurisdictional Note
Campartum is an English law term with no parallel development in American or civil law systems. It has no statutory definition in any American jurisdiction and does not appear in modern common law doctrine. Researchers in American legal history may encounter it only in the context of transplanted English chancery or common law pleading from the colonial and early republic periods.
