Definition
A Latin phrase meaning "by force and fear." Vi metuque describes the combination of physical compulsion (vis, force) and psychological compulsion (metus, fear or duress) that, when applied to a person, renders their apparent consent or agreement legally void or voidable. The phrase functions as a shorthand in civil law and equity traditions for the paired grounds that vitiate free will in contract formation, conveyance, or legal act. A transaction procured vi metuque — through force and fear — is treated as having been made without genuine voluntary consent and is subject to avoidance.
The two elements operate together as a doctrinal unit: force alone may be insufficient if no fear was instilled, and fear alone may be insufficient if it arose independently rather than through the other party's coercion. When both are present, the transaction is tainted at its foundation.

Common Confusion
Vi metuque is closely related to, but distinct from, the standalone doctrines of duress and undue influence as they are understood in common law systems. Duress in modern common law focuses primarily on the threatened harm and whether it was wrongful; vi metuque as a civil law formulation emphasizes the pairing of physical force and psychological intimidation as a single compound cause. Researchers working in mixed jurisdictions (Louisiana, Quebec, or comparative civil law contexts) should be careful not to treat modern common law duress cases as direct analogues. The civil law tradition from which vi metuque derives may require separate analysis. See also FORCE AND FEAR, the entry to which Bouvier's directly redirects.

Why It Matters in Research
This term almost never appears as a standalone doctrine in modern American common law materials. Its primary relevance is as a Latin cross-reference term in 19th-century legal dictionaries, treatises, and equity pleadings. When you encounter vi metuque in historical sources, treat it as a pointer to the force-and-fear doctrine rather than as an independent cause of action.
Bouvier's itself redirects the entry to FORCE AND FEAR — meaning the substantive analysis lives under that heading. Researchers who search only for "vi metuque" in historical corpus materials will miss the bulk of the relevant doctrine, which was cataloged under the English-language heading. Reverse searches (starting with force and fear, then connecting to vi metuque as a Latin equivalent) will be more productive.
In civil law jurisdictions and in historical equity pleadings, the Latin formulation vi metuque may appear in argument or in court opinions where the draftsman had civilian training. Scottish, Louisiana, and South African legal materials are particularly likely sources. The phrase also appears in discussions of canon law and Roman law sources bearing on contract validity.
Because vi metuque is a Latin term of art from the civilian tradition, it will not appear consistently indexed in common law digests. It is more likely to surface in: (1) 19th-century equity treatises discussing grounds for rescission; (2) comparative law scholarship; (3) annotated civil law codes; and (4) historical pleading forms.

Historical Dictionary Support
Bouvier's Law Dictionary gives vi metuque no independent substantive entry, redirecting entirely to FORCE AND FEAR. This is characteristic of Bouvier's treatment of Latin phrases that had English doctrinal equivalents — the Latin is preserved for recognition purposes while the legal content is housed under the vernacular heading. The entry also cross-references VIA (a cartway), which is an alphabetical neighbor, not a related doctrine.
No other historical dictionary in the current Law Mind shelf provides an independent entry for vi metuque. This absence is itself informative: the phrase was recognized as learned shorthand rather than as a term requiring its own doctrinal elaboration in American legal dictionaries. English and American legal writers appear to have preferred the plain-language formulation "force and fear" or simply "duress" in practice materials.
Roman law sources and civilian treatises give the concept deeper treatment. The underlying Roman law doctrine — that acts done metus causa (on account of fear) could be challenged by the actio quod metus causa — is the ancestral framework. Vi metuque as a combined phrase reflects the traditional civilian pairing of the two vitiating factors.

Jurisdictional Note
The phrase is most likely to be encountered in legal materials from civil law or mixed jurisdictions: Louisiana, Quebec, Scotland, and comparative law scholarship. In purely common law American jurisdictions, the underlying doctrine is addressed under duress, coercion, or undue influence, and the Latin formulation rarely appears in modern court opinions or statutes.

Encyclopedia Cross-Reference
The matched encyclopedia entry — Environmental Justice, Title VI, and Disparate Impact — is not substantively related to vi metuque. The "VI" in that title refers to Title VI of the Civil Rights Act of 1964, not the Latin word vis (force). No Law Mind Encyclopedia entry on contract vitiation, duress, or civil law obligations is available in the current corpus for direct cross-reference.
