Definition
A Latin term from medieval legal Latin denoting the state of liability or exposure to a fine, penalty, or amercement. Incurramentum describes not the fine or punishment itself, but the incurring of it — the condition of being subject to a financial penalty as a consequence of some act or omission. In historical English legal practice, this typically arose in connection with amercements imposed by courts or lords upon those who had violated an obligation, breached the peace, or failed to appear as required.
Why It Matters in Research
Incurramentum is an archaic term of art with no modern surviving usage. Researchers will encounter it almost exclusively in pre-modern English legal records, court rolls, treatise glossaries, and Latin-language pleading materials. Its primary research value is interpretive: understanding that the term signals a liability state — an exposure to penalty — rather than the penalty itself helps researchers read historical documents accurately and avoid conflating the condition with the sanction.
The Rapalje & Lawrence entry is notable for what it does adjacent to the definition: it cites New York cases defining the related English words "incurred" and "incurring" — suggesting that 19th-century American courts were still being asked to interpret the conceptual territory this Latin term once occupied, even after the Latin form had dropped from practice. Researchers working in 19th-century American equity or common law records may find those citations (4 Den. (N.Y.) 103 and 5 Abb. (N.Y.) Pr. 169) useful when tracing how liability-for-penalty language was interpreted after the Latin forms were abandoned.
The distinction between incurramentum (the liability) and the amercement or fine itself matters in reading historical records: a finding of incurramentum is a threshold determination, not a final sanction. Court rolls that record incurramentum may be followed by separate proceedings fixing the amount of the amercement. Researchers who treat the two as synonymous risk misreading the procedural posture of a historical matter.
All three source dictionaries cite Cowell — John Cowell's Interpreter (1607) — as the authority for this definition, making that work the primary historical anchor. Researchers seeking deeper context should consult Cowell directly.
Historical Dictionary Support
The three source dictionaries are in complete agreement: all define incurramentum as the liability to a fine, penalty, or amercement, and all trace the definition to Cowell. There is no meaningful divergence among them. Black's first edition renders the definition slightly more loosely ("The liability to Cowell. a fine, penalty, or amercement" — an apparent typographical artifact in which Cowell's name appears mid-sentence), while the second edition corrects this. Rapalje & Lawrence reproduces the definition cleanly and adds the most contextual value through its adjacent citations to American cases interpreting the concept of "incurring" liability.
None of the dictionaries provide usage examples from actual court records or treatises beyond the Cowell citation, which limits the historical depth available from dictionary sources alone. Researchers needing documentary examples should look to manorial court rolls, plea rolls, or Year Books where amercement practice is recorded.
The maxim included in Rapalje & Lawrence immediately following the incurramentum entry — Inde datæ leges ne fortior omnia posset ("The laws are made lest the stronger should be altogether uncontrolled") — appears as a separate entry and is not definitionally connected to incurramentum, though its thematic proximity to penalty and constraint is suggestive of the editorial logic of 19th-century legal dictionaries.
Jurisdictional Note
Incurramentum is a term of English legal history with no independent American doctrinal life. Its relevance in American legal research is limited to historical materials and occasional interpretive questions about pre-revolutionary English sources or early colonial court records.
