Definition
Latin. Literally, "the keys of the court." In historical Scots law, a collective term for the principal ministerial officers of a court — specifically identified as the clerk, the doomster, and the serjeant. These officers were understood to hold the functional apparatus of the court: the clerk maintained records, the doomster (also dempster) pronounced doom or formally announced the court's judgment, and the serjeant carried out enforcement and process. Together they represented the administrative and ceremonial machinery through which a Scottish court operated.

Why It Matters in Research
This term appears almost exclusively in historical sources concerned with early Scots law and procedure. Researchers encountering it in primary or secondary sources should treat it as a signal that the surrounding text addresses pre-modern Scottish court organization, likely predating the systematic reforms of the Court of Session and sheriff courts in the eighteenth and nineteenth centuries. The phrase will not appear in modern Scottish legal materials in any operative sense.
The term is useful chiefly as a navigational marker. If you encounter claves curiæ in a manuscript, court record, or institutional writing, it directs you toward sources dealing with the structure of burgh courts, baron courts, or other local jurisdictions in Scotland rather than the supreme courts. The doomster in particular was a distinctive and archaic figure — present at criminal proceedings to pronounce judgment and, later, sentence — whose office had largely disappeared by the late seventeenth century. The clerk and serjeant persisted in modified forms considerably longer.
Researchers working in Scots legal history should be aware that the precise officers grouped under this label could vary depending on the court and the period. Black's entry, citing Burrill, offers the narrowest and most formal statement; institutional writers on Scots law may describe the composition of individual courts differently. Cross-checking against sources specific to the court type under examination is advisable before treating the three listed officers as exhaustive or universally applicable.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) provides the only substantive dictionary entry for this term in the Law Mind corpus. It is terse: "The keys of the court. They were the officers of the Scotch courts, such as clerk, doomster, and serjeant." The attribution to Burrill — Alexander Burrill's Law Dictionary and Glossary (1850–1851) — places the lineage of the definition squarely in the mid-nineteenth century American legal lexicography tradition, which drew heavily on earlier English and Scottish institutional sources for Latin and historical terms of this kind.
No other dictionary in the corpus addresses claves curiæ independently. The term is absent from modern legal dictionaries, reflecting its obsolescence as operative vocabulary. Researchers should note that the Latin phrase in Black's appears without the diacritical mark over the final "æ" in curiæ — a common typographical simplification in American legal printing of the period. Both spellings (curiz in older typefaces representing the æ ligature) refer to the same phrase and concept.
The deeper history of the metaphor — keys as instruments of access, authority, and control — was a commonplace of medieval institutional language (compare clavis regni, the "key of the realm"), and the application to court officers reflects an organic use of the image: the officers who open and close the court's proceedings and hold its records are its "keys."
