Definition
EXI is a Latin abbreviation used in historical legal records, derived from the verb *exhibere* (to exhibit, to produce, to make available). In its documentary and procedural sense, *exi* appears as a shorthand notation in court records and writs signaling that something — a person, document, or object — has been produced, made available, or brought forth as required. The term connects directly to the Roman law concept of *exhibere*: to place something in public power or possession so that the party entitled to examine or act upon it has the practical means to do so.
The underlying legal meaning of *exhibere*, from which *exi* derives, carries a specific technical weight: it is not merely to show a thing but to make it genuinely accessible — to give the opposing party or the court the real opportunity to take hold of the subject matter, not just sight of it.
Common Confusion
*Exi* should not be confused with *exitus* (issue, exit, or outcome), which appears in different procedural contexts in historical records. Nor should it be conflated with *exhibuit* (he exhibited, third person singular perfect), though both derive from the same root. The abbreviation form *exi* in marginalia or docket entries typically signals a completed act of production or presentment, while related abbreviations from *exitus* concern the final issue or result of a proceeding. Researchers who fail to distinguish these may misread a notation about production of a person or document as a notation about case outcome.
Why It Matters in Research
Researchers encountering *exi* in manuscript court records, plea rolls, or chancery documents need to recognize it as procedural shorthand rather than a substantive legal term. Its appearance in the margins of medieval and early modern English records most often signals compliance with a production requirement — that a writ of *habeas corpus*, a subpoena, or a production order has been satisfied by bringing the subject before the court.
The deeper research value lies in tracing the Roman law ancestry. Burrill's entry connects *exi* to the *actio ad exhibendum*, the Roman civil action specifically designed to compel production of a thing so that a subsequent action could proceed. Understanding this lineage clarifies why English equity and common law courts developed analogous production mechanisms: the concept that a party cannot effectively litigate what they cannot see or access runs continuously from Justinian's Digest through to discovery doctrine in modern civil procedure.
Researchers working in pre-1800 English and American records should also be alert to the distinction Burrill preserves from the Digest: *prehendenda copiam facere* (to give the opportunity of taking hold) versus *in publico potestatem* (giving power in public). This is not a trivial distinction. The first formulation implies physical possession; the second implies legal access for the purpose of litigation. In equity records particularly, production orders grounded in the second formulation did not necessarily transfer custody of the thing produced.
Historical Dictionary Support
Burrill's is the primary historical dictionary source for this term, and his entry is valuable precisely because it does not treat *exi* in isolation but grounds it in the Roman law substrate. Burrill quotes two passages from Justinian's Digest (Dig. 43.5.3.8 and Dig. 10.4.2) to draw out the technical meaning: production is not mere display but the creation of genuine practical access for the party who needs to act. This distinction between showing and making available for legal action is the conceptual core that persists across centuries of procedural development.
What Burrill does not address — and what no single historical dictionary adequately covers — is how *exi* functioned as a working abbreviation in actual court record-keeping practice. For that, paleographic guides and records scholarship (such as work on the Public Record Office's holdings of plea rolls) are necessary supplements. The abbreviation's meaning in context is stable, but its graphic form varies across hands and periods.
