Definition
A negative averment is an allegation in a pleading that asserts a substantive fact through negative language — that is, it states that something does not exist, did not occur, or is not in a particular condition. Although grammatically framed as a denial, a negative averment functions as an affirmative claim in substance. Because the pleader is asserting a new fact (rather than merely denying the opponent's allegation), the burden of proving that fact falls on the party making the averment.
The classic illustration: a plaintiff alleging that leased premises are "not in repair" is not simply denying the defendant's position — the plaintiff is asserting a state of affairs that must be independently established at trial. The negative form of the words does not relieve the pleader of the burden of proof.
Common Confusion
A negative averment is not the same as a traverse. A traverse (or general denial) is a pure denial of what the opposing party has alleged; it introduces no new factual assertion and shifts no burden. A negative averment, despite its negative wording, introduces a substantive factual claim. The distinction matters for pleading sufficiency and for allocating the burden of proof. Researchers working in older common-law pleading materials should be alert to courts and treatise writers using "denial," "traverse," and "negative averment" loosely or interchangeably — the terms are not synonyms.
Why It Matters in Research
This term belongs almost entirely to the world of common-law pleading and is rarely encountered in modern practice under notice-pleading regimes (post-Federal Rules of Civil Procedure, 1938; post-equivalent state reforms). Researchers will encounter it primarily in:
— Pre-20th century American and English case law, especially in actions at common law where technical pleading governed;
— Treatises on common-law pleading (Chitty, Stephen, Gould) that dissect the pleading rules in granular detail;
— Older equity and assumpsit records where the distinction between traverse and negative averment affected whether a replication or rejoinder was required.
The key research trap: modern readers may misread a historical pleading document or case opinion and treat a negative averment as a simple denial, thereby misunderstanding which party bore the burden of proof and why the case turned out as it did. If a 19th-century court rules that a party "having averred the negative must prove it," the court is applying this doctrine — not creating an anomaly.
The term has essentially no active life in contemporary pleading law. If it appears in a modern document, the context is almost certainly historical citation, academic analysis, or a jurisdiction that preserved common-law pleading forms unusually late.
Historical Dictionary Support
Black's Law Dictionary captures the operative distinction well: a negative averment is "negative in form" but "affirmative in substance," and the party alleging it must prove it. The example given — premises not in repair — is the standard illustration drawn from common-law pleading practice. Black's attributes the formulation to "Brown," a reference to Brown's treatise on pleading, consistent with 19th-century common law authority.
Bouvier's is notably sparse: it defines the term as simply "an averment in some of the pleadings in a case in which a negative is asserted." This definition, while technically accurate, omits the crucial functional point — that such an averment carries a burden of proof despite its negative form. Bouvier's entry is useful for confirming the term's currency in pleading practice but provides little analytical guidance. Researchers relying on Bouvier's alone would miss the doctrine's core significance.
Neither historical dictionary addresses the modern obsolescence of the term or its relationship to notice pleading. That gap is significant: a researcher working only from these sources might assume the doctrine remains operative in contemporary American courts, which it generally does not.
Jurisdictional Note
The doctrine of negative averment is a product of common-law pleading and applies most fully in jurisdictions that retained code or common-law pleading rules into the late 19th or early 20th century. Under the Federal Rules of Civil Procedure and substantially similar state notice-pleading systems, the technical pleading categories that gave negative averments their distinct significance have largely dissolved. A small number of states were slower to adopt notice pleading; researchers working in those jurisdictions should check local pleading history before assuming the doctrine is entirely inoperative.
