Definition
A Scottish legal term referring to land held in common by two or more proprietors, or by those who have acquired rights of servitude over it. Commonty describes not merely a right to use shared land but the land itself as a category of property — ground over which multiple parties hold concurrent interests, whether by co-ownership or by formal servitude rights recognized under Scots law.
Commonty is the Scottish equivalent of what English law calls a common, but it operates within a distinct legal tradition and carries its own body of doctrine governing division, enclosure, and the nature of the interests held. Division of commonties in Scotland was governed by statute, most significantly the Division of Commonties Act 1695, which provided a mechanism for proprietors to petition for partition and consolidation of their individual shares into separate holdings.
Common Language
Modern common usage (Wiktionary): A right to own land held in common between two or more people, sometimes subject to servitudes; also used to refer to the land itself.
Historical common usage (Webster's 1913): A common; a piece of land in which two or more persons have a common right.
The common and legal definitions are closer here than for many shared-land terms, but the gap that matters is this: ordinary usage treats commonty primarily as a right, while Scots law treats it as a category of land — the ground itself, not merely an entitlement to use it. The distinction matters because partition proceedings operated on the land as a physical object capable of division, not merely on an abstract bundle of rights.
Common Confusion
Commonty is frequently assimilated to the English concept of common land or common rights, but the two systems are legally distinct. English common rights (rights of common) are typically appendant or appurtenant to a dominant tenement and do not give the commoner a proprietary share in the land itself. Scottish commonty, by contrast, could involve full co-ownership by multiple proprietors, not merely a servitude right over another's land. Researchers using English legal dictionaries to interpret Scottish historical records will find the English framework misleading. The word "common" in English sources and "commonty" in Scottish sources describe related but non-identical institutions.
Why It Matters in Research
Commonty is almost exclusively a term of Scots law. Researchers encountering it in English-language legal dictionaries should treat those entries as brief glosses rather than authoritative guides — Black's and Burrill's each reproduce a single sentence derived from Bell's Dictionary of the Law of Scotland, and none of the standard English dictionaries engages with the procedural law governing commonties.
The critical research issue is historical: the Division of Commonties Act 1695 drove a long process of enclosure in Scotland that transformed commonties into individual holdings over the eighteenth and nineteenth centuries. Records from this period — petitions, decrees of division, sasine records — will use the term in its full technical sense. A researcher who reads "commonty" as simply meaning "common land" in the English sense may misread the nature of the interests being adjudicated.
Jurisdictional scope is narrow: this is a term of Scottish private law with no operative meaning in English, Welsh, or Irish legal contexts, and no counterpart in American law. It appears in the Law Mind corpus almost entirely in Scottish historical materials, comparative property law discussions, and the historical dictionaries that borrowed from Bell.
Pay attention to the distinction between commonty held by co-proprietors (more analogous to tenancy in common) and commonty held by those with servitude rights only. Historical sources sometimes blur this distinction, and the nature of the interest determined what remedies were available under the 1695 Act.
Historical Dictionary Support
All three dictionary sources — Black's (1st ed.), Black's (2nd ed.), and Burrill's — give virtually identical one-sentence definitions, each tracing back to Bell's Dictionary of the Law of Scotland. Burrill adds a citation to 36 English Law and Equity Reports 20, which represents one of the few points at which Scottish commonty doctrine surfaced in English legal reporting. The uniformity of these entries reflects the limits of the English-language legal dictionary tradition when dealing with Scots law: compilers recorded Bell's formulation without elaborating on the statutory framework, the division process, or the distinction between proprietary and servitude-based interests. Researchers should not mistake brevity for completeness. Bell's own dictionary entry and Scottish institutional writers — Stair, Erskine, Bell's Principles — provide the substantive doctrine these English-language entries omit.
Jurisdictional Note
Commonty is a term of Scots law only. It has no legal meaning in English law, American law, or other common law jurisdictions. Scottish land law operates on civilian-influenced foundations that differ structurally from English common law, and terms like commonty should not be mapped onto English equivalents without care.
