Definition
A Latin and Law Latin phrase meaning "at court" or "to court." Used in early common law and feudal practice to indicate presence before a court or the act of bringing a matter before a judicial tribunal. The phrase appears most often in the compound expression ad curiam vocare — to summon to court, that is, to call a party to appear before a judicial body to answer a claim or obligation.
Why It Matters in Research
Ad curiam is a relic phrase encountered primarily in pre-modern English and feudal legal records. Researchers working in early common law materials, Year Books, or feudal tenure documents may find it in procedural contexts describing the obligation of a tenant or party to attend court, or in records of summons. It does not appear as a term of art in modern American or English legal practice, so its presence in a source is a strong signal that the document is archaic or that the author is drawing directly from a classical or feudal legal framework.
The key research trap is misreading the phrase in context. Ad curiam on its own means presence at or direction toward a court. Ad curiam vocare is the action — the summoning. Conflating the two can distort the procedural meaning of a passage describing whether a party was already before the court versus being compelled to appear. In feudal tenure law, the obligation to attend the lord's court (suit of court) was a distinct legal duty, and language tracking that obligation used formulations like this one. Burrill's citation to Feud. Lib. 2, tit. 22 — the Libri Feudorum, the medieval compilation of Lombard feudal law — places this phrase squarely in that tradition.
Researchers consulting Black's (1st and 2nd editions) will find nearly identical entries. The slight variation in the introductory gloss ("Atacourt" in the first edition versus "At a court" in the second) reflects no substantive difference; it is simply a typographical artifact of the era.
Historical Dictionary Support
All three source dictionaries agree on the core translation and usage. Black's (1st Ed.), Black's (2nd Ed.), and Burrill's all anchor the phrase to the same authority: 1 Salk. 195, a reference to Salkeld's Reports, a compilation of English common law cases from the late seventeenth and early eighteenth centuries. Burrill's adds the Libri Feudorum citation, giving the phrase deeper feudal grounding that Black's does not supply.
None of the source dictionaries provide extended treatment. The entries are glosses, not analyses — appropriate for a phrase that functions as procedural vocabulary rather than a substantive legal concept. Researchers should not expect these entries to illuminate the feudal law of suit of court in any depth; they confirm translation and point to authority, nothing more.
