Definition
An enrolment; the act of enrolment, or a specific enrolment itself. The term appears in old English legal practice to describe the official recording of a document, proceeding, or instrument upon a roll — the physical medium by which courts and administrative offices maintained their permanent records in medieval and early modern England. The word functions both as a noun of process (the act of enrolling) and as a noun of product (the resulting enrolled record).
Why It Matters in Research
This term is encountered almost exclusively in pre-modern English legal materials — court records, writs, and procedural treatises from the medieval and early modern periods when Latin remained the formal language of legal documentation. Researchers working in Year Books, plea rolls, patent rolls, close rolls, or the records of Chancery will find irrotulamentum used where a modern source would simply say "enrollment" or "entry of record."
The practical trap is terminological: a researcher unfamiliar with the Latin form may not recognize that irrotulamentum and its verb irrotulare refer to the same procedural act described in English sources as "enrollment" or "enrolment." Missing this equivalence can cause gaps in tracing procedural chains — particularly in Chancery practice, where enrollment of deeds and decrees carried legal significance distinct from mere execution of the instrument.
The term also surfaces in contexts involving the enrollment of statutes and royal instruments, where the enrolled record on the Parliament Roll or Chancery Roll could be the authoritative version of the text. For historians of English legal procedure, the distinction between a document that had been irrotulatum (enrolled) and one that had not could determine its evidentiary weight and legal effect.
Historical Dictionary Support
Burrill's Law Dictionary provides the essential gloss: irrotulamentum derives from the verb irrotulare (to enroll) and is defined simply as "enrolment; an or the enrolment," citing the Registrum Omnium Brevium (Reg. Orig. 221) as authority. The Registrum Omnium Brevium — the register of original writs — is a recognized authority on English common law forms and procedure, lending the citation credibility as a genuine point of reference in old English practice.
No broader disagreement or development across historical dictionaries is resolvable here because the surviving dictionary treatment is narrow. What Burrill provides is essentially all the lexicographic record: a clean Latin-to-English mapping with no documented doctrinal evolution. The term did not develop competing meanings or travel into modern law; it remained fixed to the procedural context of roll-based record-keeping and became obsolete as that system gave way to modern court filing and registration practices.
Researchers should note that Burrill does not elaborate on the distinction between irrotulamentum as a verb of process versus a product — the enrolled record itself — though both uses appear in primary sources.
Jurisdictional Note
Irrotulamentum is specific to the English legal tradition and its historical court and administrative systems. It does not appear in Scots law, civil law systems, or American legal practice except as a historical reference to English antecedents.
