Definition
In legal usage, CHECKER is the old Scotch form of EXCHEQUER — the royal treasury and fiscal court that administered Crown revenues in Scotland, as in England. The term appears in historical Scottish legal instruments and commentary as a variant spelling reflecting Scots orthographic conventions, and carries no independent legal meaning beyond its identification with the Exchequer institution.
Common Language
Modern common usage (Wiktionary): One who checks or verifies something; a checkout clerk who tallies purchases; one who hinders or stops something.
Historical common usage (Webster's 1913): One who checks.
The gap between common and legal meaning is complete. In ordinary English, "checker" denotes a person performing verification or a retail cashier — active, present-tense roles. In legal usage, the term is purely archaic and geographic: a Scots spelling of a specific royal institution, not a descriptor of any person or function. A researcher encountering "checker" in a modern context has no reason to suspect a legal meaning; a researcher in Scottish legal records has no reason to read the common meaning into it.
Common Confusion
CHECKER should not be confused with CHEQUER, the preferred English spelling of the same institution, nor with EXCHEQUER, the Latinized and anglicized form. All three refer to the same underlying institution; the variation is orthographic and jurisdictional, not substantive. Researchers may also encounter CHEKER or CHEKKER in medieval English records — again, spelling variants only. None of these forms signals a distinct legal body.
Why It Matters in Research
Researchers working in pre-Union Scottish legal records, treatises, or glossaries will encounter CHECKER as a routine variant for the fiscal tribunal and treasury functions that EXCHEQUER describes in English sources. The practical significance is navigational: keyword searches in digitized Scottish legal corpora that use only "exchequer" will miss documents using "checker," and vice versa. Any research into Scottish revenue law, Crown fiscal administration, or the jurisdiction of the Scottish Exchequer court should run searches on both forms.
The term has no meaningful post-Union currency. After the Acts of Union (1707), Scottish and English exchequer functions were progressively consolidated, and the distinctive Scots spelling faded from formal usage. CHECKER in a post-1707 Scottish legal document would be an archaism or a copyist's habit, not a reference to a distinct institution.
No confusion with the modern commercial or gaming senses of "checker" should arise in any legal research context, but researchers new to Scottish legal history should be alerted that the term is not a reference to an officer, a verifier, or any kind of clerk — it names a court and treasury.
Historical Dictionary Support
All three source dictionaries agree without variation: CHECKER is the old Scotch form of EXCHEQUER, nothing more. Black's (1st ed.) states this in a single clause. Burrill adds the authority of Skene's De Verborum Significatione and cross-references SCACCARIUM (the Latin root, from scacarium, the checkered cloth used to count revenues, which gave the institution its name across all its linguistic variants). Black's 2nd edition adds the same definition and appends a note on CHEFE — a separate Anglo-Norman term meaning weregild — which appears in Burrill's entry as a follow-on term and is unrelated to CHECKER proper.
What the historical dictionaries do not address: the institutional history and jurisdiction of the Scottish Exchequer court itself, the relationship between the Scottish and English Exchequers before and after Union, or the procedural context in which the term appears in practice. Researchers needing that depth must move beyond definitional sources to institutional legal histories and the Scots legal treatises (such as Skene) that the dictionaries cite.
Jurisdictional Note
CHECKER as a legal term is exclusively Scottish in origin and application. It does not appear in English, Welsh, or Irish legal usage as a form of "exchequer." Researchers in English records will not encounter it; researchers in Scottish records should treat it as an equivalent of EXCHEQUER for all substantive purposes.
