Definition
Quare clausum fregit (often abbreviated "qu. cl. fr." or "QCF") is a Latin phrase meaning "wherefore he broke the close." It names the historical common law form of trespass action brought to recover damages for an unlawful entry upon another's land. A "close" in this context is a legally defined parcel of land — not necessarily enclosed by a fence or wall — and "breaking" it means crossing its boundary without right or permission.
In the traditional declaration for this action, the plaintiff alleged that the defendant, with force and arms, broke and entered the plaintiff's close, trod down his grass, and otherwise injured him. The "force and arms" language was a legal fiction; actual physical force was not required. Any unauthorized entry upon land — even a footstep — constituted the trespass.
Quare clausum fregit was one of two principal branches of the action of trespass at common law: trespass quare clausum fregit addressed injury to real property, while trespass vi et armis or trespass de bonis asportatis addressed personal injury or injury to personal property. Together these forms dominated much of early Anglo-American civil pleading.
Common Language
Wiktionary: "A writ for land trespass."
The common language definition is accurate but thin. The legal significance lies in the procedural and pleading architecture the phrase represents — not just the act of trespass, but a specific writ form with a defined declaration structure, fixed Latin averments, and distinct pleading rules governing what the defendant could and could not deny by a general plea. "A writ for land trespass" captures the skeleton; it misses the technical substance that matters in historical legal research.
Core Elements
The action of trespass quare clausum fregit required the plaintiff to establish:
1. POSSESSION OR RIGHT OF POSSESSION: The plaintiff needed to be in actual or constructive possession of the close at the time of the entry. Ownership alone, without possession, was insufficient; that defect sent the plaintiff to ejectment instead.
2. AN ENTRY: Any physical crossing of the boundary of the close, however slight, satisfied this element. The entry need not cause measurable damage — the law presumed injury from the intrusion itself.
3. WITHOUT LAWFUL AUTHORITY: The entry had to be unauthorized. License, easement, legal process, or other justification operated as a defense, not a negation of the plaintiff's prima facie case.
4. CAUSAL CONNECTION TO CLAIMED DAMAGE: While nominal damages were available for the bare entry, plaintiffs typically pleaded specific harms — crops destroyed, soil broken — to support a larger damages recovery.
Recognized Forms
/SUBTYPES
The action appeared in two procedural postures in historical practice:
TRESPASS QUARE CLAUSUM FREGIT PROPER: The full action at law for damages resulting from an unlawful entry on land.
QUI TAM VARIANT / STATUTORY ACTIONS: Some statutory regimes grafted onto the quare clausum fregit form imposed double or treble damages for specific categories of unlawful entry (e.g., timber cutting on another's land), preserving the common law pleading structure while expanding the remedy.
Why It Matters in Research
Researchers encountering this term in historical American and English sources should keep several navigational points in mind.
PLEADING TRAPS: The plea of the general issue ("not guilty") in quare clausum fregit operated differently from the general issue in other actions. Per Rapalje & Lawrence, the general issue denied the commission of the trespass at the place alleged but did not put in issue the plaintiff's possession or right of possession. To contest possession, the defendant had to traverse it specially. A researcher reading old case reports must identify which issues were actually contested — general issue alone resolved much less than it appeared to.
POSSESSION VS. OWNERSHIP DISTINCTION: One of the most consequential features of this action is that it ran to the possessor, not necessarily the owner. A tenant in possession could maintain quare clausum fregit against a third party — or sometimes even against the landlord. Historical sources that describe this as an "owner's" remedy are imprecise. When researching property disputes in early American courts, the question "who was in possession?" often matters more than "who held title?"
EJECTMENT AS THE ALTERNATIVE: Quare clausum fregit coexisted with ejectment throughout the common law period. Where the plaintiff sought title determination rather than damages for a specific intrusion, ejectment was the proper vehicle. Conflating the two actions in historical research leads to misreading the strategic choices parties made in selecting their form of action.
SURVIVAL IN MODERN LAW: The Latin phrase largely disappeared from American pleading after code pleading reforms in the nineteenth century (beginning with the New York Field Code of 1848) and was eliminated wholesale under notice pleading regimes following the Federal Rules of Civil Procedure (1938). Modern trespass to land doctrine is the functional descendant, but the pleading formalities — and the case law interpreting them — belong to the common law era. When citing pre-code cases involving quare clausum fregit, the procedural posture of the old form shapes what issues were and were not resolved.
CORPUS CONNECTIONS: This term connects directly to research on common law pleading forms, the writ system, trespass doctrine, real property possession rules, and the transition from common law to code pleading in American jurisdictions.
Historical Dictionary Support
Black's Law Dictionary provides the core definition accurately: the action for damages for unlawful entry on land, with the declaration averring that the defendant "with force and arms, broke and entered" the close. The "force and arms" language Black preserves is important; it signals the fiction embedded in the form and explains why early courts found no inconsistency between the formal averment and cases involving entirely peaceable, non-violent entries.
Bouvier's Law Dictionary cross-references the full treatment under TRESPASS and TRESPASS QUARE CLAUSUM FREGIT, consistent with Bouvier's organizational habit of collecting related doctrine under the broadest heading. Researchers using Bouvier should follow that cross-reference; the main entry is sparse by design.
Rapalje & Lawrence adds the most procedurally precise note: the general issue in this action operates as a denial of trespass at the place alleged but not as a denial of the plaintiff's possessory right. This distinction — largely glossed over in Black's — is essential for reading the pleading record in historical cases correctly.
None of the historical dictionaries give sustained treatment to the possession-versus-ownership distinction or to the transition out of the form under code pleading. For that doctrinal history, secondary treatise literature (Shipman on Common Law Pleading; Stephen on Pleading) is necessary.
Jurisdictional Note
The action was substantially uniform across English and American common law jurisdictions in its classical form. American states varied in how long they retained the Latin pleading formulas after code reform; some jurisdictions preserved quare clausum fregit as an accepted shorthand in trespass declarations well into the late nineteenth century even after formal code adoption. Researchers working in specific state archives should check when that state adopted code pleading and what transitional rules governed.
