Definition
A Latin term from old English legal practice meaning an entry. Derived from the Latin *intrare* (to enter), *intratio* referred to the act or record of entering something — most commonly the formal entry of a proceeding, plea, or instrument into the official record of a court. In medieval and early modern legal usage, the term functioned both as a noun describing the act of entry and as a descriptor for the written record resulting from that act.
Common Confusion
INTRATIO and INTRINSECUS are adjacent Latin terms in old practice sources and occasionally appear in close proximity in medieval texts, which can create confusion. They are distinct: *intratio* refers to the act of entry (as in entering a record), while *intrinsecus* refers to that which is within or intrinsic — specifically, in old English land law, the category of service that was expressed within the charter and owed to the chief lord, as opposed to forinsecus service owed outward to a superior lord. A researcher encountering either term in a medieval roll or treatise should take care not to conflate the two simply because both derive from the Latin root *intra*.
Why It Matters in Research
*Intratio* appears almost exclusively in medieval and early modern English legal records — plea rolls, court rolls, and the procedural treatises that described their operation. Researchers working in Latin-language primary sources from this period should recognize the term as a technical procedural marker indicating that something has been formally entered into the record, analogous to what later practice would call an entry or filing.
Because the term fell out of active use as English replaced Latin in legal proceedings — a process formalized by statute in the mid-seventeenth century — it rarely appears in post-Restoration sources except in antiquarian or treatise discussions of old practice. Any encounter with *intratio* in a corpus source is thus a reliable signal that the document dates from, or is describing, pre-modern practice.
The term's close neighbors in Burrill — *intrinsecus* and *forinsecus* — are context-dependent and carry distinct substantive meaning in feudal tenure law. When researching records involving service obligations or charter interpretation, researchers should consult those entries alongside *intratio* to avoid misreading the passage.
Historical Dictionary Support
Burrill's Law Dictionary provides the only historical dictionary treatment among the Law Mind shelf sources and is brief: *intratio* is defined simply as "an entry" in old practice, with the Latin derivation noted. Burrill does not develop the term further, which is itself informative — it suggests that by the time of his compilation, *intratio* had sufficiently receded from active practice that extended treatment was unnecessary. The term's chief value in his dictionary is taxonomic, preserving the Latin vocabulary of the old record for researchers navigating medieval sources.
No significant divergence appears across sources, as the term is not treated in other shelf dictionaries. The absence of elaboration in the historical record confirms that *intratio* was a workaday procedural term rather than a term of art with contested or evolving meaning.
Jurisdictional Note
*Intratio* is a term of English legal history and appears in the Latin records of English courts. It has no independent doctrinal life in American law and is not a term of practice in any modern jurisdiction.
