Definition
The state of being publicly and widely known, typically applied in legal contexts to facts, conditions, or acts that are so generally known within a community or relevant audience that no formal notice or proof is required to establish their existence. Legal notoriety functions as a threshold concept: when a fact, claim, or condition achieves sufficient notoriety, the law may treat it as known — or constructively known — by those who ought to have encountered it.
In practice, notoriety appears most frequently in two distinct legal contexts:
1. Evidence and judicial notice. Facts of sufficient notoriety may be judicially noticed, meaning a court accepts them without requiring evidentiary proof. The notoriety of the fact — its general, undisputed public currency — substitutes for formal proof.
2. Property and possession. In adverse possession doctrine, "notorious" possession is one of the required elements. A possessor's occupation of land must be notorious in the sense that it is open and visible, such that the true owner would have reasonable notice of the adverse claim. Here, notoriety is a legal standard of conduct, not merely a description of reputation.
Common Language
Modern common usage (Wiktionary): An infamous or notorious condition or reputation.
Historical common usage (Webster's 1913): The quality or condition of being generally or publicly known, commonly used in an unfavorable sense; as, the notoriety of a crime.
Both the common and historical definitions carry a pejorative weight — notoriety implies something shameful or scandalous is widely known. The legal usage is value-neutral. When a court asks whether a possessor's occupation was notorious, or whether a fact is notorious enough for judicial notice, no negative moral judgment attaches. Researchers importing the common meaning into legal sources will misread both the threshold and the purpose of the standard.
Common Confusion
NOTORIETY vs. NOTICE. These concepts are related but distinct. Notice is a legal mechanism by which knowledge of a fact is formally or constructively attributed to a party — it is a legal status. Notoriety is the underlying condition of public knowledge from which constructive notice may be inferred. A fact may be notorious without having been formally noticed; and notice may be given of facts that are not notorious. In adverse possession, notorious possession contributes to constructive notice to the owner, but the two terms describe different aspects of the analysis.
NOTORIETY vs. FAME. In general usage, fame and notoriety are sometimes treated as interchangeable (though with the latter carrying negative connotation). In legal research, fame is irrelevant to the notoriety analysis; what matters is whether the relevant community — neighbors, affected parties, a reasonable owner — would have observed the fact, not whether it was broadly celebrated or condemned.
Why It Matters in Research
Researchers will encounter notoriety most heavily in two bodies of doctrine, and the word works differently in each. Conflating them is a frequent source of confusion.
In adverse possession cases, "notorious" is a term of art describing the quality of possession, not the character of the possessor. Historical cases often use "open, visible, and notorious" as a compound phrase; breaking it apart and searching for "notorious" alone may surface irrelevant results. The standard for what counts as sufficiently notorious varies by jurisdiction and by the nature of the land — agricultural use in a rural setting may establish notoriety more readily than intermittent improvements in an urban setting.
In the judicial notice context, notoriety appears in older sources as the operative test for whether a court could take notice of a fact without proof. Modern doctrine under the Federal Rules of Evidence and their state equivalents has partially displaced the older notoriety language with the more precise "generally known within the territorial jurisdiction" formulation, but older cases and treatises will use notoriety as the functional equivalent. Researchers working in pre-twentieth century materials should expect notoriety to carry much of the conceptual weight now distributed across the notice doctrine.
A subtler trap: in defamation law, public notoriety bears on whether a plaintiff is a public figure, which controls the fault standard applicable to the claim. Here the common-language meaning (infamy, wide public knowledge) bleeds back into the legal analysis, but as a factual predicate rather than a legal standard. Notoriety in this context is a question of degree and is fact-specific.
Historical sources also use notoriety in the context of publication — particularly in older ecclesiastical, probate, and marriage law — where a fact was deemed legally operative once it achieved community notoriety, substituting for formal recording or registration. This usage has largely disappeared from modern practice but will appear in historical corpus research.
Historical Dictionary Support
Black's Law Dictionary defines notoriety simply as "the state of being notorious or universally well known," which accurately captures the term's core meaning but does little to illuminate how the concept functions across doctrine. The definition does not distinguish between the evidentiary use and the property use, nor does it flag the pejorative weight the term carries in common usage that is absent in legal application.
Webster's 1913 is more revealing in this respect: its note that the term is "commonly used in an unfavorable sense" signals the gap that legal usage creates. Legal notoriety is not about moral condemnation — it is about the public availability of a fact or condition to any reasonable observer.
No significant divergence appears among historical dictionary sources on this term; the core meaning has been stable. What the historical dictionaries collectively miss is the doctrinal specificity of notorious possession as a legal standard of conduct in property law — a use that is not merely descriptive but functions as a legal element requiring proof.
Jurisdictional Note
The elements of adverse possession, including the notorious-possession requirement, vary by state in their formulation and application. Some jurisdictions require that the possession be notorious enough to charge the owner with actual constructive notice; others apply a more objective reasonable-observer standard. Researchers should treat historical cases from one jurisdiction cautiously when extending the analysis to another.
