Definition
A statement of defense is a formal pleading filed by a defendant in response to the plaintiff's statement of claim. It is the defendant's primary written answer to the plaintiff's allegations, in which the defendant admits those facts not in dispute, denies those that are, and sets out any additional facts or affirmative defenses on which the defendant intends to rely. The statement of defense is the structural counterpart to the statement of claim, and together the two pleadings define the boundaries of the dispute to be resolved at trial.
The term originates in English High Court practice under the Judicature Acts and the Rules of the Supreme Court, which replaced the older common law system of special pleading with a more streamlined framework of pleadings. Under that system, the statement of claim and statement of defense replaced the declaration and plea respectively. The terminology passed into the procedural rules of several Commonwealth jurisdictions and remains the standard designation in England, Canada, Australia, and other countries following the English tradition.
In jurisdictions that follow U.S. federal practice or state codes modeled on it, the equivalent document is called an answer. The substance is largely the same: admission or denial of each allegation, assertion of affirmative defenses, and, where permitted, counterclaims.
Common Confusion
STATEMENT OF DEFENSE vs. ANSWER: These terms describe functionally equivalent documents but belong to different procedural traditions. "Answer" is the standard American term. "Statement of defense" is the standard Commonwealth term. Researchers working across jurisdictions or in historical sources must be alert to this divergence. Treating the two as interchangeable for substantive purposes is generally correct; treating them as interchangeable when analyzing procedural rules or court forms of a specific jurisdiction is not.
STATEMENT OF DEFENSE vs. DEFENSE: "Defense" is the broader concept — any legal theory, fact, or argument by which a defendant seeks to defeat, reduce, or excuse liability. A statement of defense is the document; a defense is the legal theory it may contain. The document can plead multiple defenses simultaneously.
Core Elements
A properly constituted statement of defense typically addresses each of the following:
Admissions: Explicit acceptance of specific allegations in the statement of claim. Admitted facts are removed from the controversy and need not be proved at trial.
Denials: Explicit rejection of specific allegations. Most procedural regimes require that denials be specific; a bare general denial is either prohibited or given limited effect.
Affirmative allegations: New facts asserted by the defendant that go beyond simply contradicting the plaintiff's case — for example, facts supporting accord and satisfaction, limitation, contributory fault, or any other affirmative defense.
Alternative pleading: Where the rules permit, the defendant may plead inconsistent defenses in the alternative.
Why It Matters in Research
The primary navigational challenge is jurisdictional terminology. Historical English and Commonwealth sources use "statement of defense" where American sources use "answer." A researcher tracing procedural history across English and American sources from the late nineteenth and early twentieth centuries must track this terminological divergence carefully. The Judicature Acts reforms of the 1870s are the origin point: sources predating those reforms will not use this term at all, referring instead to the plea, the rejoinder, or other forms from the system of special pleading.
The historical entries in the source dictionaries are all truncated — none reproduces the full procedural rules governing the document's contents, timing, or consequences of omission. Researchers relying solely on dictionary definitions will miss the operational detail that governed how statements of defense were actually drafted and what happened if allegations were neither admitted nor denied. For that material, the relevant sources are the English Rules of the Supreme Court (Order 18 under the 1965 Rules; Order 19 under predecessor rules), and their Commonwealth equivalents.
In Commonwealth jurisdictions today, the statement of defense is governed by court rules that specify strict timelines (typically 28 days from service of the statement of claim, subject to extension), require specific pleading of facts rather than conclusions, and impose consequences — including deemed admissions — where allegations are not expressly addressed. These procedural consequences are significant and often not apparent from the definition alone.
A second research trap: the phrase "statement of defense" appears in some non-pleading contexts — particularly in administrative and tribunal proceedings — where it denotes a written submission responding to a complaint or charge, without carrying the same formal pleading rules. Context must be confirmed before applying procedural requirements derived from court practice.
Historical Dictionary Support
All three source dictionaries locate the term squarely in English High Court practice and describe the same basic function: the statement of defense responds to the statement of claim by admitting or denying its allegations and, where necessary, adding new matter. Rapalje & Lawrence and Bouvier are marginally more complete than the truncated Black's entry, each beginning to explain the relationship to the indorsement on the writ — relevant where an action was brought under Order 14 (summary judgment procedure) and no full statement of claim was filed separately. This detail reflects a procedural nuance that Black's entry omits. None of the three entries addresses the consequences of failing to plead to a particular allegation (deemed admission), which is among the most practically significant aspects of the document. All three treat the term as an English law matter, which was accurate at the time of writing; the subsequent adoption and local adaptation of equivalent terminology across Commonwealth jurisdictions is not reflected in any of them.
Jurisdictional Note
The term "statement of defense" is standard in England, Canada, Australia, New Zealand, and other Commonwealth jurisdictions. American federal practice and most U.S. state practice use "answer" instead. Within Commonwealth jurisdictions, procedural details — timing, form, consequences of non-compliance — vary by jurisdiction and must be verified against local rules.
