Definition
Leave to defend is a procedural mechanism in civil litigation by which a defendant, served with a claim under a summary or expedited judgment procedure, applies to the court for permission to contest the action on its merits. Without such permission, the plaintiff is entitled to enter judgment by default upon satisfying minimal proof requirements. The court grants leave to defend only when the defendant demonstrates a genuine triable issue of fact or law — that is, a real and arguable defense, not merely a bare denial or a speculative one.
The term is most closely associated with summary judgment procedures and their historical antecedents. In its classic English form, leave to defend operated as the procedural gatekeeping mechanism that separated cases with a genuine dispute from those where the debt or liability was plainly established: if the defendant could show cause, the court opened the case to full proceedings; if not, judgment was entered summarily.
In modern practice, the concept survives across multiple procedural systems in varying forms, most prominently in:
1. Summary judgment applications — where courts assess whether sufficient dispute exists to warrant a full trial.
2. Debt and negotiable instruments proceedings — where creditors may obtain accelerated judgment on bills of exchange, promissory notes, or liquidated claims, subject to the defendant's right to seek leave.
3. Default judgment regimes — where a defendant who has not appeared may apply, sometimes retrospectively, for leave to defend by setting aside the default.

Common Confusion
Leave to defend is sometimes conflated with leave to appear, but the two are distinct steps. Leave to appear refers to permission simply to enter the proceedings at all; leave to defend goes further and authorizes the defendant to contest the merits. In early English summary procedure under the Bills of Exchange Act 1855 and its successors, a defendant had to obtain leave to appear and defend within a prescribed window — collapsing the distinction in practice — but modern procedure typically treats appearance and defense as separate entitlements, with summary judgment then challenging whether defense should proceed.
The term is also sometimes confused with the general right to defend, which every defendant enjoys as of right in ordinary litigation. Leave to defend is distinctive precisely because it arises in accelerated or summary procedures where that ordinary right has been suspended pending a threshold showing.

Why It Matters in Research
Researchers face two significant traps with this term.
First, the procedural context is everything. The phrase "leave to defend" does not mean the same thing across time periods or jurisdictions. In 19th-century English practice, it was a highly specific creature of summary debt procedure tied to bills of exchange legislation. In mid-20th-century Commonwealth practice, it migrated into broader summary judgment rules. In contemporary U.S. federal practice, the exact phrase is rarely used — the functional equivalent is the showing required to survive a motion for summary judgment under Federal Rule of Civil Procedure 56 — but the concept is alive under different terminology. A researcher reading an English or Commonwealth authority using "leave to defend" and assuming it maps directly onto U.S. summary judgment doctrine risks misreading the procedural stakes involved.
Second, the standard for granting leave has evolved and varies. Early English authorities set a fairly low threshold — any colorable defense would do. Later Commonwealth courts refined the standard into tiered categories: unconditional leave (full defense permitted), conditional leave (defense permitted subject to paying money into court or giving security), and refusal of leave (judgment entered). This tiered structure has significant implications for how cases are resolved and how courts balance creditor efficiency against debtor access to merits. Researchers using historical sources should be alert to which standard the authority applies.
For corpus research, this term appears most frequently in materials touching negotiable instruments, commercial debt recovery, and civil procedure reform — particularly in English and Commonwealth sources from 1855 onward. It is much less visible in American primary sources, where summary judgment and default judgment doctrine developed along separate doctrinal lines.

Historical Dictionary Support
Bouvier's entry situates leave to defend squarely in the English Bills of Exchange Act 1855 (18 & 19 Vict. c. 67), which introduced the summary writ procedure for actions on bills and notes commenced within six months of maturity. Under that regime, judgment was available to the plaintiff on proof of service unless the defendant obtained leave to appear and defend within twelve days. Bouvier notes that this procedure was retained — with modification — under the Judicature Act, confirming that the mechanism survived procedural consolidation in England.
Bouvier's entry is incomplete as preserved in the source material, cutting off before describing how the Judicature Act modified the procedure. Researchers should treat this entry as a starting point rather than a complete account. The entry correctly identifies the historical origin of the term in negotiable instruments litigation but does not address the broader migration of "leave to defend" into general summary procedure, nor does it speak to Commonwealth or American developments. The gap between Bouvier's narrow framing and the term's wider modern usage is itself historically instructive: what began as a specialized debt-recovery device became a general procedural concept.

Jurisdictional Note
The phrase "leave to defend" is most at home in English and Commonwealth procedural systems, where it remains standard terminology in summary judgment and debt recovery contexts. In U.S. practice, the concept is functionally present but the precise phrase is uncommon; researchers should search under "summary judgment," "conditional appearance," and "setting aside default" when working in American sources. Canadian and Australian courts use the term more directly, often with explicit doctrinal frameworks distinguishing unconditional from conditional leave.
