Definition
In legal usage, notorious means openly known, visible, or manifest — particularly in the sense that relevant parties are presumed to have notice of a fact or condition. The word carries two distinct legal meanings depending on context:
1. Evidence law. A fact or condition so widely and publicly known that it requires no formal proof. Courts have treated notorious matters as the equivalent of judicially noticed facts, relieving a party of the burden of establishing them through evidence.
2. Adverse possession. The claimant's use or occupation of land must be notorious in the sense that it is open and visible, conducted in a manner that a reasonable owner inspecting the property would observe and recognize as a claim of ownership. Notorious possession does not require actual knowledge by the true owner; it requires that the character of the possession be such that the owner is charged with constructive notice of it.
A secondary, older legal sense — now largely obsolete in formal doctrine — carried a reputational dimension: notorious as meaning known to one's discredit, as in notorious insolvency (a condition of insolvency publicly and widely understood to exist).
Common Language
Modern common usage (Wiktionary): Generally or widely known, typically for something negative; infamous. Also used neutrally to mean simply well-known or of common knowledge.
Historical common usage (Webster's 1913): "Generally known and talked of by the public; universally believed to be true; manifest to the world; evident — usually in an unfavorable sense; as, a notorious thief; a notorious crime or vice."
The gap worth noting: ordinary usage loads notorious with moral condemnation — a notorious person is infamous for wrongdoing. Legal usage strips most of that moral freight. In adverse possession, notorious describes the quality of possession (visible, open, unconcealed) without any suggestion of wrongfulness. A claimant's notorious use of land is a legal virtue, not a vice. Researchers encountering the word in property law documents should not import the common pejorative meaning.
Common Confusion
Notorious and open are sometimes treated as synonyms in adverse possession doctrine, but courts and treatises distinguish them. Open typically means the possession is not hidden or concealed. Notorious adds the further idea that the use is conducted in the manner that an owner of that type of land would use it — sufficiently visible and consistent that a reasonably attentive true owner would be on notice of the adverse claim. Some jurisdictions merge the two into a single "open and notorious" element; others treat them as analytically separate. Researchers should check which formulation governs in the relevant jurisdiction.
Notorious should also be distinguished from actual notice. Notorious possession does not require proof that the true owner actually saw or knew of the claimant's use. It is a constructive notice standard: the possession must have been of a character that a diligent owner could have discovered upon inspection.
Core Elements
In the adverse possession context, courts generally assess whether possession is notorious by asking:
- Visibility: Was the claimant's use visible and apparent on the land itself (structures, cultivation, fencing, regular activity)?
- Consistency with ownership: Did the claimant use the land in the manner a true owner of similar property would use it?
- Constructive notice: Would a reasonably attentive owner, upon inspecting the property, have recognized the claimant's use as an assertion of ownership?
The standard is objective. It focuses on what the possession looked like to an outside observer, not on the subjective awareness of either party.
Why It Matters in Research
The most research-critical use of notorious in the Law Mind corpus is as one of the required elements of adverse possession. The encyclopedia entry at property_85 addresses this directly and should be the starting point for any adverse possession research. Note that notorious appears as part of the compound phrase "open and notorious" in most modern American adverse possession doctrine — the two words are often paired but may carry independent analytical weight depending on jurisdiction.
In historical sources, notorious carries a broader evidentiary meaning (facts too well-known to require proof) that predates and partially overlaps with the modern judicial notice doctrine. Researchers reading 18th- and 19th-century sources on evidence should recognize that notorious fact arguments were precursors to, but not identical with, modern judicial notice under Federal Rule of Evidence 201. The standard was looser and less formalized.
The phrase notorious insolvency appears in older commercial and bankruptcy-adjacent sources. It referred to a debtor's widely known inability to pay debts — a condition that could affect creditor priorities or preferences. This usage is largely archaic in modern bankruptcy practice but may appear in historical commercial law documents.
Researchers should also be alert to the Scottish legal term notour, flagged by Rapalje & Lawrence, which functions similarly to notorious in Scots law (open, public, manifest) and appears in older treatises touching on Scottish practice.
Historical Dictionary Support
The historical dictionaries are in substantial agreement on the core meaning: manifest, generally known, open. All treat notorious in adverse possession as requiring that the character of the holding put the owner on constructive notice. Bouvier's formulation is the most precise for property law purposes: "the character of the holding must possess such elements of notoriety that the owner may be presumed to have notice of it and of its extent."
Anderson's Dictionary offers the most useful positive framing — "manifest to all persons; generally known; open: as, a notorious act of ownership" — which captures well the non-pejorative legal usage in property contexts.
Where the historical sources are weakest: none of the dictionaries develops a crisp analytical test for what makes possession sufficiently notorious, which reflects the reality that no settled rule existed. Black's (both editions) acknowledges this gap explicitly in the evidence context ("There does not seem to be any recognized rule as to what matters are deemed notorious"), and the same uncertainty ran through property cases as well. Modern case law has done more to define the standard, but the historical sources are candid that the line was always case-by-case.
Jurisdictional Note
Adverse possession requirements — including the notorious element — vary by state statute and case law. Some jurisdictions require a heightened showing of notoriety for wild or rural land, where open use is inherently less visible. Researchers should not assume that a description of the notorious element from one state's cases translates directly to another.
