Definition
A Latin maxim meaning "in a secular court" or "in a temporal court." The phrase distinguishes proceedings before civil or royal courts from proceedings before ecclesiastical courts. In medieval and early modern legal systems, the question of whether a matter fell in foro seculari or in foro ecclesiastico was not merely procedural but jurisdictional in the most fundamental sense — determining which legal system, with its own rules, officers, and sanctions, had authority over the dispute or the person.
Why It Matters in Research
Researchers working in pre-modern English legal sources will encounter this phrase in jurisdictional disputes between church and crown. The distinction it marks was live and contested for centuries, particularly with respect to clergy (benefit of clergy), marriage and legitimacy, probate of wills, tithes, and defamation. A matter described as cognizable in foro seculari was being claimed for the royal courts — common law, equity, or the prerogative courts — and removed from the bishop's jurisdiction.
When reading early sources, researchers should be alert to the fact that the phrase typically appears not to describe a settled rule but to argue for one. Its presence in a text often signals a contested boundary. Blackstone uses the concept in discussing the separation of ecclesiastical from temporal jurisdiction as it developed after the Conquest, and Fleta (the late thirteenth-century legal treatise) touches on the same territorial logic of competing forums.
The practical stakes of this distinction have disappeared from modern common law systems, where ecclesiastical courts retain only narrow jurisdiction over matters internal to the Church of England. For researchers working in American legal history, the concept is almost entirely historical — the First Amendment foreclosed any formal ecclesiastical court jurisdiction in the American colonies from independence onward. References to in foro seculari in American legal writing are therefore either antiquarian or borrowed from English authorities to make a conceptual point about separation of church and state.
Be cautious when this phrase surfaces in nineteenth-century American treatises or opinions: the author is almost always citing English or canonical sources, and the phrase carries no operative American jurisdictional content. It is rhetorical or historical, not descriptive of a live forum choice.
Historical Dictionary Support
Bouvier's entry is minimal — three words of definition ("in a secular court") followed by a citation chain to Blackstone's Commentaries (Book I, Chapter 2, discussing the history of English courts and the separation of lay and ecclesiastical jurisdiction) and to Fleta (Book II, Chapter 57, Section 14). This brevity is itself informative: by Bouvier's era, the forum distinction the phrase described had been largely settled for generations, and the phrase was already a term of art appearing mainly in historical or comparative argument rather than in live pleadings.
Bouvier does not attempt to explain the substantive content of what belonged in foro seculari versus in foro ecclesiastico — that content was too historically variable and context-dependent to summarize in a dictionary entry. Researchers seeking the substantive scope of secular versus ecclesiastical jurisdiction must go to primary treatise sources: Blackstone's Commentaries Book I provides the most accessible English-language account; Fleta and Bracton supply the medieval common law foundation; and for the ecclesiastical side, Ayliffe's Parergon Juris Canonici and Gibson's Codex Juris Ecclesiastici Anglicani address what the church courts actually claimed.
No historical dictionary in the Law Mind corpus attempts a fuller synthesis of this term. Researchers should treat the Bouvier entry as a pointer, not an analysis.
Jurisdictional Note
The phrase has no operative jurisdictional significance in American law. In English law, the distinction between secular and ecclesiastical forums, though vastly reduced, remains technically relevant for matters within the Church of England's Consistory Courts. Researchers working in canon law or comparative ecclesiastical law contexts should consult jurisdiction-specific sources rather than common law dictionaries.
