Definition
A Latin term meaning "apparent" or "appearing." In legal usage, *apparens* describes something that is regularly before a court, visible in the record, or formally presented to judicial notice. The term carries both a procedural sense — that which has appeared or been brought before a tribunal — and a substantive sense — that which is evident or manifest on the face of a matter.
The term is most frequently encountered through the maxim derived from it: *De non apparentibus et non existentibus eadem est ratio* — "Respecting things which do not appear and things which do not exist, the rule is the same." This principle holds that a fact not shown in the record, not pleaded, and not established before the court is treated in law precisely as if it did not exist at all. Absence from the record equals legal nonexistence.

Common Language
Modern common usage (Wiktionary): "Apparent" in ordinary English means readily visible, obvious, or seeming to be true based on appearances, with the caveat that appearances may be deceiving ("apparent but not real").
Historical common usage (Webster's 1913): Apparent — "Open to view; visible to the eye; within sight or view; evident; manifest; indubitable."
The legal sense of *apparens* inverts one nuance of ordinary usage. In common speech, "apparent" can suggest something that merely seems true but may not be. In legal context, the *apparens* / *non apparens* distinction is absolute and procedural: what has not been put before the court simply does not legally exist for purposes of that proceeding, regardless of its actual truth in the world. The doctrine is less about perception and more about the formal boundaries of the record.

Why It Matters in Research
Researchers encounter *apparens* almost exclusively in two contexts: maxim collections and early common law pleading treatises. Its primary significance is as the root concept behind the *de non apparentibus* maxim, which remains a foundational principle of evidence and procedure — a court cannot act on facts not in the record.
The trap for historical source researchers is treating *apparens* as a purely philosophical or rhetorical term when it had genuine procedural teeth. In early English practice, the rule enforced strict pleading discipline: if a party failed to plead a fact, that fact was invisible to the court regardless of how well-known it might be outside the courtroom. Later procedural reforms (notice pleading, judicial notice doctrines, and modern evidence codes) absorbed and softened this principle, but did not eliminate it.
When searching the Law Mind corpus, *apparens* will surface in Latin maxim compilations, glossaries of law Latin, and treatises on pleading and evidence. It connects directly to discussions of judicial notice, the record on appeal, and the principle that appellate courts are generally confined to what the record contains. A researcher tracking the *de non apparentibus* maxim should also search for its English paraphrase forms, as later writers dropped the Latin while preserving the rule.
The term itself rarely appears in modern case law as *apparens*, but the underlying doctrine is cited continuously under its English formulations.

Historical Dictionary Support
Burrill's Law Dictionary provides the only direct entry among the shelf sources. Burrill treats *apparens* straightforwardly as a Latin adjective meaning "apparent; appearing; that which appears, or is regularly before a court," and anchors it immediately to the *de non apparentibus* maxim, citing *Caudrey's Case* (6 Co.) and Broom's *Legal Maxims* as authorities for the proposition that things not appearing are treated as nonexistent.
No other shelf dictionaries provide a standalone entry for *apparens*, reflecting its status as a term of art embedded in Latin maxim usage rather than a freestanding doctrinal category. Burrill's treatment is characteristically economical: the definition, the maxim, the authority, and the English gloss. What Burrill does not do — and what a researcher should not expect historical dictionary sources generally to supply — is trace the procedural application of the maxim across different stages of litigation or explain how the principle was modified by equity practice, where courts were sometimes more willing to take cognizance of facts outside the strict record.

Jurisdictional Note
The *de non apparentibus* principle operates across common law jurisdictions, but its practical reach varies by procedural system. Jurisdictions that have adopted notice pleading or flexible joinder rules have effectively narrowed the domain in which the strict *apparens/non apparens* distinction operates. In appellate practice, the confinement of review to the record below remains the most active modern expression of the principle in virtually all common law systems.
