Definition
A verb used in Scots law meaning to exchange, particularly in the context of land transfers. When parties excamb property, they swap parcels of land with one another rather than conducting a conventional sale. The corresponding noun form is excambion, meaning the exchange itself. The transaction is the functional equivalent of what English law calls an exchange of lands.
Common Language
Modern common usage (Wiktionary): To exchange, specifically during transfers of land.
Historical common usage (Webster's 1913): Not recorded. The term did not enter general English usage.
The common and legal meanings are effectively identical here, but the word is so thoroughly confined to Scots legal practice and historical legal writing that a researcher encountering it outside that context should treat the usage with caution. It is not interchangeable with "exchange" in English common law instruments.
Common Confusion
Excamb and its Latin ancestor excambiare (also spelled excambire) appear in both Scots law sources and old English law sources, but they are not the same usage. In old English legal Latin, excambiare was used in medieval conveyancing records and glossed by Spelman and Cowell; the related noun excambiator meant an exchanger or broker. In Scots law, excamb is the vernacular legal term of art still appearing in reported cases as late as the nineteenth century. Researchers should not assume that an English source using excambiare and a Scots source using excamb are drawing on the same legal tradition or carrying the same procedural rules.
Why It Matters in Research
Excamb is a term you are most likely to encounter when working through Scots property records, conveyances, or appeal cases that reached the House of Lords from Scotland. Its appearance in 6 Bell's Appeal Cases is the anchor citation across all historical dictionaries, and Bell's Dictionary of the Law of Scotland is the primary Scots source for the term's doctrinal context.
Two traps for researchers working in historical sources:
First, the Latin forms. Burrill records both excambiare and excambire as Latin variants used in old English law, with excambiator as the agent noun. If you are reading medieval English conveyancing documents or a glossary like Spelman's or Cowell's, you may encounter these Latin forms without any signal that you have crossed from English into a Scots-derived tradition. Always check whether the surrounding document is English or Scots in origin before applying doctrinal rules from one system to the other.
Second, terminology drift in secondary sources. Nineteenth-century English legal writers occasionally borrowed excamb or excambion when discussing property exchanges in a general or antiquarian context. That borrowing does not mean the Scots procedural rules for excambion applied. In Scots law, excambions historically required certain formal elements and could carry distinct warranty obligations; an English writer using the word decoratively carried none of that freight.
For corpus connections: excamb sits squarely within the broader family of property transfer vocabulary. Researchers tracing exchange transactions should follow the cross-references to exchange, quid pro quo in property contexts, and—for the Latin layer—to cambiare-derived terms in medieval conveyancing glossaries.
Historical Dictionary Support
The four source dictionaries are consistent on the core meaning: excamb means to exchange, it is Scots law, and the Bell citation is the shared documentary anchor. There is no meaningful divergence on definition.
Bouvier adds the most doctrinal context, noting the derivation from the Latin ex cambium and directing the reader to the entry on Exchange. Burrill is the most etymologically thorough, recording both Latin variants (excambiare, excambire) and the agent noun excambiator with the Cowell attribution, and flagging the old English law usage as distinct from the Scots term. Black's in both editions gives the minimal but accurate gloss without elaboration.
What the historical dictionaries collectively miss is any substantive treatment of how excambion transactions were structured under Scots law—what formalities were required, how warranties ran, or how the term was applied in the Bell case itself. For that, Bell's Dictionary and the institutional Scots writers (Stair, Erskine, Bell's Principles) are necessary supplements.
Jurisdictional Note
Excamb is a term of Scots law and has no operative counterpart in English common law or American law. Researchers working in English or American sources will not encounter it as a live legal term; its appearance in those sources is antiquarian or etymological. For Scots law research, the relevant jurisdiction is Scotland, and post-1707 appeal decisions from Scotland to the House of Lords (such as the Bell cases) are the most accessible English-language sources.
