Definition
A now-abolished common law writ directed at annulling (voiding) a fine that had been levied upon lands held in ancient demesne, where that fine operated to the prejudice of the lord of the manor. The writ recognized that tenements within ancient demesne occupied a privileged legal category — lands held by the Crown at the time of the Domesday survey — and that ordinary conveyancing mechanisms, including the levying of a fine in the royal courts, could not be permitted to alter or encumber those tenements in a way that harmed the manorial lord's established rights over them.
In medieval conveyancing practice, a "fine" (in its technical sense) was a fictitious lawsuit concluded by agreement, used as a method of transferring or settling title to real property. Because ancient demesne lands were subject to their own customary courts and could not generally be conveyed by the common law forms available for freehold land, a fine levied in the royal courts touching such land was considered irregular and voidable. This writ was the procedural mechanism by which the lord could have such a fine undone.

Common Language
The individual words of this term carry ordinary meanings, but their combination describes a wholly technical medieval legal instrument. The word "fine" in modern English typically refers to a monetary penalty. "Annulling" means voiding or canceling. These common meanings, while not misleading on their face, give no useful purchase on the legal operation of this writ. The "fine" at issue here was not a penalty but a species of conveyance — a collusive action used to transfer land — and the writ's purpose was to cancel such a conveyance on the specific ground that the land in question was protected ancient demesne.

Why It Matters in Research
This term will appear almost exclusively in pre-modern English legal sources — writs registers, Year Books, and treatises on real property practice from the medieval and early modern periods. Researchers encountering it should be alert to two points.
First, the writ belongs to the broader cluster of ancient demesne doctrine, a highly specialized area of medieval English land law that operated largely outside the common law courts. Understanding this writ requires familiarity with what ancient demesne was, how it was identified (primarily by reference to Domesday Book), and what protections attached to it. Without that background, the writ's purpose is opaque.
Second, the writ is listed in the Registrum Omnium Brevium (the register of original writs) and belongs to a large family of now-abolished writs that populated the medieval Chancery's writ register. Researchers working in Law Mind's historical English law corpus should treat this term as a marker pointing toward ancient demesne materials more broadly, rather than as a term likely to generate substantial standalone case law.
The term does not appear in American legal materials. It has no modern application. Its research value is purely historical — understanding the architecture of medieval English real property law, the limits on alienability imposed by ancient demesne status, and the procedural mechanics by which lords protected manorial rights.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed., Supplemental) describes this as an abolished writ for disannulling a fine levied of lands in ancient demesne to the prejudice of the lord, with a citation to Reg. Orig. 15 — a reference to the Registrum Omnium Brevium, the authoritative register of original writs in English practice. This entry is brief to the point of minimalism, which is characteristic of the Supplemental volume's treatment of obsolete medieval writs.
No other source in the available corpus provides an entry for this term. The Black's treatment confirms the writ's existence and function but offers no discussion of its procedural requirements, its history of use, or the circumstances under which it fell out of use. Researchers seeking depth will need to consult primary sources — the Registrum itself and treatments of ancient demesne in Bracton, Coke's Institutes, or Fitzherbert's Natura Brevium — rather than relying on dictionary sources alone.

Jurisdictional Note
Strictly English in origin and application. This writ has no counterpart in Scottish, Irish, or American law. Ancient demesne as a legal category was never transplanted to the American colonies or to any other common law jurisdiction outside England. The writ is of historical interest only.
