Definition
In Scots feudal law, a subordinate or derivative right in land — specifically, the right held by a subvassal in lands granted to him by a mesne lord (a vassal who had himself received the lands from a superior). The base right stands below the superior's dominium directum in the feudal hierarchy: the subvassal holds the lands not from the Crown or ultimate superior directly, but through an intermediate lord. The right is "base" in the sense of being lower in the chain of feudal tenure, not in the sense of being defective or inferior in quality.
Common Language
Modern common usage (Wiktionary): "The right which a disposer acquires when disposing of feudal property."
Historical common usage (Webster's 1913): "Base" as an adjective meant low in place, rank, or estimation; of humble birth; morally low.
The common meaning of "base" as morally inferior or of low social standing is misleading here. In the legal context, "base" is a technical term of feudal hierarchy, describing position in a chain of tenure — not the worth or legitimacy of the right itself. The Wiktionary definition, while touching feudal ground, points to a disposition-side interest rather than the holding-side interest captured by historical legal dictionaries, and should not be relied upon for research purposes.
Why It Matters in Research
Base right is a term of Scots feudal property law, and researchers will encounter it almost exclusively in sources dealing with Scottish land tenure prior to the abolition of feudal tenure in Scotland by the Abolition of Feudal Tenure etc. (Scotland) Act 2000. English and American sources that mention the term are typically borrowing it from Scots law and will cite Bell's Dictionary and Digest of the Law of Scotland as the authority — as all three historical dictionaries in the Law Mind corpus do.
Researchers should be alert to two navigational points. First, "base" in this context is a term of art derived from feudal hierarchy, and searching corpus materials using "base" as a keyword will return significant noise from other legal uses (base fee, base tenure, base court). Pairing the search with "subvassal," "mesne lord," or "Scots law" will narrow results appropriately. Second, the term appears in older American legal dictionaries primarily as a glossary entry for Scots and civil law concepts, not as a term with operative American significance. Its presence in Black's, Rapalje & Lawrence, and Burrill reflects those dictionaries' ambition to document comparative and historical law, not an indication that base right had independent doctrinal currency in common law jurisdictions.
For researchers working on feudal land history, comparative property law, or the history of Scottish land reform, the term connects structurally to the broader architecture of subinfeudation and the feudal pyramid — concepts that illuminate why Scotland's feudal tenure system required comprehensive statutory abolition as late as 2000.
Historical Dictionary Support
The three historical dictionaries in the Law Mind corpus are in complete agreement: Black's, Rapalje & Lawrence, and Burrill all define base right identically as a subordinate right, specifically the right of a subvassal in lands held by him, and all three cite Bell's Dictionary as their sole authority. This uniformity signals that none of the three conducted independent analysis — they are each transmitting Bell's definition. Researchers should treat Bell's Dictionary and Digest of the Law of Scotland as the primary source and the Law Mind dictionary entries as secondary conveyances of that definition.
What the historical dictionaries do not address is how base right related functionally to the rights of the immediate superior or the ultimate overlord, nor do they address the practical consequences of a subvassal's base right in the event of forfeiture or recognition proceedings. For that level of analysis, Bell's own work and Scottish institutional writers (Craig, Stair, Erskine) are the appropriate resources.
Jurisdictional Note
Base right is a term specific to Scots feudal law and has no operative equivalent in English common law or American property law. English law addressed the equivalent structural problem through the Statute of Quia Emptores (1290), which effectively prohibited subinfeudation in England. Scotland's feudal tenure system persisted until statutory abolition in 2000.
