Definition
Latin: "willing." A person is volens when they either expressly consent to something or tacitly acquiesce in it by making no opposition. The term appears most often not in isolation but as the operative word in the maxim volenti non fit injuria — "to the willing, no injury is done" — which holds that a person who freely consents to a risk or act cannot afterwards complain of it as a legal wrong. In that context, being volens is both the factual finding and the legal threshold: the question courts ask is whether the claimant was truly volens with respect to the specific risk that materialized.
A secondary phrase from the same root, voluit sed non dixit ("he willed but he did not say"), addresses a different problem: the gap between unexpressed intention and actual statement, particularly in the construction of instruments. These two phrases share the Latin root but serve entirely different doctrinal functions and should not be conflated.
Common Language
Modern common usage (Wiktionary): "In the state of mind where one voluntarily accepts a specific risk."
Historical common usage (Webster's 1913): Webster's 1913 does not carry a standalone entry for volens, reflecting the term's status as legal Latin rather than naturalized English vocabulary.
Editorial note: The common gloss — "voluntarily accepting a risk" — captures the tort law application but narrows the term in a way the Latin does not. Volens in classical legal usage encompasses any willing assent, express or tacit, across contract, tort, and family law. Treating it as synonymous with assumption of risk imports a tort-specific limitation that the underlying maxim does not contain.
Common Confusion
Volens is frequently encountered as shorthand for the full maxim volenti non fit injuria, and researchers sometimes treat the two as interchangeable. They are not: volens names the mental state or condition of the person; the maxim states the legal consequence of that condition. A claimant may be volens with respect to one risk and not another, which is why the scope of consent is litigated even when some degree of willingness is undisputed. Separately, volens is sometimes confused with scienter (knowledge) or with contributory negligence. Knowledge of a risk does not equal acceptance of it. A person can be fully aware of a danger and still not be volens if they had no genuine freedom to refuse exposure.
Why It Matters in Research
Volens is a gateway term. Researchers who encounter it in a primary source need to follow it into the volenti doctrine, and that path branches depending on era and jurisdiction. In older English common law sources — including Bracton, where Burrill traces the maxim's earliest English appearance — the doctrine was applied broadly and the threshold for finding a person volens was relatively low. By the late nineteenth and early twentieth centuries, particularly in the context of employer-employee relations, courts began demanding evidence of not just knowledge but free and voluntary acceptance of the specific risk, narrowing what it means to be truly volens.
In American sources, the volenti maxim was largely absorbed into the assumption of risk doctrine, which was itself substantially modified or abrogated in many jurisdictions following adoption of comparative fault regimes. This means a researcher working with American materials from after the 1960s may find the Latin term displaced by "assumption of risk" language without any signal that the underlying concept has changed — or changed significantly.
For contract and matrimonial law sources, where Black's references Shelf. Mar. & Div., the maxim operates on consent logic rather than risk logic, and the analytical frame differs from the tort context. Researchers should not carry tort-derived definitions of volens into those materials without adjustment.
The maxim voluit sed non dixit, also triggered by the root term, appears in construction of wills and contracts and warrants its own research thread distinct from the consent-and-risk line.
Historical Dictionary Support
All three source dictionaries agree on the core Latin definition and on the central role of volenti non fit injuria. Black's (both editions) and Burrill converge on the formulation that willingness encompasses both express consent and tacit non-opposition — a formulation drawn from Calvinus's Lexicon Juridicum.
Burrill adds the historically significant observation that the maxim appears in English law as early as Bracton, grounding the doctrine in medieval common law rather than later reception of Roman principles. This is a meaningful data point that Black's omits.
Both Black's editions include the maxim voluit sed non dixit, and both appear to truncate the entry mid-sentence in surviving text — a researcher relying on those sources alone should be aware the entry as printed is incomplete and should consult Burrill or a fuller edition for the construction-law application.
None of the historical dictionaries engage with the doctrinal narrowing of volens in employment and industrial accident contexts, which was actively litigated in the period when these dictionaries were produced. For that development, the dictionaries must be supplemented with case law and treatise sources.
Jurisdictional Note
In English law, volenti non fit injuria remains a recognized defense with continuing doctrinal life. In most American jurisdictions, the concept has been substantially recast as assumption of risk and restructured under comparative fault frameworks, making the Latin term less common in modern American case law. Researchers working across jurisdictions should verify whether a given court is applying a traditional volenti analysis or a comparative assumption of risk standard, as the practical threshold differs.
