Definition
Falsa monita (Latin: "false money") is a term from Roman civil law denoting counterfeit currency — money that has been debased, forged, or falsely represented as genuine coin. The term encompasses the making, passing, or possession of fraudulent coinage and formed the basis for criminal prohibitions against currency fraud in the late Roman imperial legal system.
Why It Matters in Research
Falsa monita is an archaic Latin term of limited direct application in modern common law research, but it carries significant navigational value in two contexts.
First, researchers working in Roman law, canon law, or early continental legal sources will encounter this term in discussions of monetary crimes alongside related Latin phrases such as adulteratio monetae (debasement of coinage) and crimen falsi (the broader crime of forgery or fraud). Understanding that falsa monita sits within the crimen falsi family helps researchers locate relevant passages in civilian sources and track how monetary fraud was conceptually organized in Roman jurisprudence.
Second, researchers tracing the historical development of counterfeiting law in common law jurisdictions should note that the conceptual content of falsa monita — criminal liability for false coinage — passed into English and American law through a different doctrinal channel. Common law counterfeiting developed independently of the Roman category and was treated as a species of treason in early English law (coining being an offense against the sovereign's prerogative) rather than as a civil-law fraud offense. Researchers should not assume continuity of doctrine simply because the subject matter overlaps.
The Bouvier citation to Cod. 9, 24 refers to Title 24 of Book 9 of the Codex Justinianus, the section addressing falsifiers and monetary fraud. Researchers using Bouvier to trace a doctrine back to Roman authority should go directly to the Corpus Juris Civilis rather than relying on Bouvier's brief gloss, as the Codex provisions address a range of coining offenses with distinctions that Bouvier does not reproduce.
Historical Dictionary Support
Bouvier's Law Dictionary defines falsa monita simply as "counterfeit money" and cites Cod. 9, 24 of Justinian's Codex. This is accurate as far as it goes but represents the minimum possible treatment. No other historical dictionaries in the Law Mind corpus provide an entry for this term, which reflects the term's confined role as a technical Latinism of Roman law rather than a working term of common law practice.
The brevity of coverage across historical sources is itself informative: falsa monita does not appear to have been a term of art in English or American legal proceedings, where counterfeiting was prosecuted under statutory regimes using common law vocabulary. Its appearance in Bouvier is characteristic of his project of incorporating civilian learning into an American legal dictionary, rather than evidence that the term had active currency in American courts.
Jurisdictional Note
Falsa monita is a term of Roman civil law and has no direct counterpart as a technical term in modern U.S., English, or other common law jurisdictions. Modern counterfeiting law in the United States is governed by federal statute; in England, by statutes descending from early currency legislation. Researchers in civil law or mixed jurisdictions (Louisiana, Quebec, Scotland, South Africa) may find the Roman classification more proximately relevant.
