Definition
Failure is a broad legal term with no single fixed meaning; its significance depends almost entirely on context. In each setting, it describes either a shortfall in performance, a deficiency in legal sufficiency, or a collapse of commercial capacity.
1. General legal usage. The neglect or omission of a legal duty; an inability to meet a legal standard or requirement. Courts use "failure" to describe anything from a litigant's failure to appear, to a statute's failure to provide adequate notice, to a party's failure to perform a contractual obligation.
2. Failure of consideration. The absence or want of a legally sufficient consideration in a contract, rendering it unenforceable. May be total (no consideration whatsoever) or partial (consideration promised but only partly performed or delivered).
3. Commercial/insolvency usage. The suspension or abandonment of business by a merchant, bank, or commercial enterprise due to insolvency — an inability to pay debts as they come due. In this sense, "failure" is treated as synonymous with insolvency.
4. Failure of proof / failure of evidence. In litigation, the insufficiency of evidence to sustain a claim or defense, often grounds for dismissal or directed verdict.
5. Failure to appear. A party's or witness's nonappearance at a required court proceeding, which may constitute contempt, result in a default judgment, or — for a criminal defendant — constitute a separate criminal offense.
6. Organ/medical failure (adjacent legal usage). In tort, probate, and insurance contexts, the clinical failure of a bodily organ may be relevant to causation, capacity, or policy triggers, though "failure" in this sense follows medical rather than distinctly legal definition.

Common Language
Modern common usage (Wiktionary): The state or condition of not meeting a desirable or intended objective; the opposite of success. Also, omission to do something that ought to have been done.
Historical common usage (Webster's 1913): Cessation of supply or total defect; a failing; deficiency. Omission; nonperformance. Want of success. A becoming insolvent; suspension of payment.
The gap between common and legal meaning is contextual rather than definitional: in ordinary speech, "failure" is evaluative and somewhat vague (falling short of a goal). In law, "failure" is frequently a term of art that triggers specific consequences — rescission of a contract, dismissal of a claim, criminal liability, or a finding of insolvency. A researcher who treats "failure" as merely descriptive in a legal source may miss its operative force.

Common Confusion
FAILURE vs. BREACH. In contract law, "failure to perform" and "breach" are often used interchangeably but carry different implications. Breach typically implies a voluntary or wrongful act; failure can describe either a wrongful omission or a legally excused nonperformance (as in failure due to impossibility). Context and jurisdiction determine whether the terms are equivalent.
FAILURE OF CONSIDERATION vs. LACK OF CONSIDERATION. These are distinct defenses. Lack of consideration means no consideration existed at formation. Failure of consideration means consideration was promised but subsequently did not materialize or was not rendered. The distinction matters for remedies: lack of consideration voids a contract from the outset; failure of consideration may support rescission or a damages claim.

Why It Matters in Research
"Failure" is one of the most context-sensitive words in the legal corpus. Its meaning shifts dramatically depending on subject matter, and older sources compound this by using it interchangeably with "default," "insolvency," "neglect," and "omission" — terms that modern law treats as distinct.
In commercial law research, nineteenth-century sources routinely equate "failure" with insolvency. A source describing a merchant's "failure" in an 1870s case is reporting a bankruptcy event, not merely a shortfall in performance. Readers must adjust accordingly.
In contract law research, "failure of consideration" appears as a defense in historical pleadings far more commonly than in modern ones, which tend to use "lack of consideration" or "breach." The terms have not always been carefully distinguished in older texts, so tracing a failure-of-consideration defense through historical sources requires watching for terminological slippage.
In criminal and procedural research, "failure to appear" and "failure to file" carry specific statutory consequences that are jurisdiction-dependent. The same phrase in a nineteenth-century source may describe a purely procedural consequence (default) rather than the independent criminal offense it can constitute today.
The tax context is a specific modern trap: "failure to file" and "failure to pay" are distinct penalty triggers under federal tax law, and conflating them — or importing older general usage into a tax research context — leads to error.

Historical Dictionary Support
The historical sources converge on two core meanings: a general legal sense (neglect or omission of duty; deficiency; want) and a commercial sense (insolvency). Black's (1st Ed.) states the commercial usage plainly: "failure," applied to a merchant or mercantile concern, "must be regarded as synonymous with insolvency." Black's (2nd Ed.) expands slightly, adding "suspension or abandonment of business by a merchant, manufacturer, bank, etc., in consequence of insolvency" and, for the general sense, "deficiency, want, or lack; ineffectualness; inefficiency as measured by some legal standard."
Anderson's offers the most complete general definition — "the state or condition of being wanting; a falling short; deficiency or lack; defect, want, absence; default; defeat" — and correctly identifies "failure of consideration" as a distinct subcategory. Bouvier's mirrors this structure, noting that in legal parlance "the neglect of any duty may be a failure, and the commission of any fault a delinquency," while tracking the commercial synonym with insolvency.
What the historical dictionaries largely omit: the procedural and criminal uses of "failure" (failure to appear as a criminal offense, failure to file as a statutory penalty trigger) that dominate modern research. The nineteenth-century sources are reliable for commercial and contract contexts but offer little guidance for contemporary procedural or regulatory applications of the term.

Jurisdictional Note
"Failure to appear" carries criminal consequences in all U.S. jurisdictions but penalties, classifications, and triggering conditions vary. Federal tax "failure to file" and "failure to pay" are governed by the Internal Revenue Code and are distinct from state tax equivalents, which may use different terminology. In contract law, whether a partial failure of consideration supports rescission or merely a damages reduction is treated differently across common law jurisdictions.
