Definition
A writ of extent issued directly at the suit of the Crown for the recovery of a debt owed to the sovereign. Extent in chief was the primary and most powerful form of extent — a summary royal remedy that allowed the Crown to seize and appraise a debtor's lands, goods, and body simultaneously, without the procedural steps required of ordinary creditors. Upon execution, the debtor's estate was delivered to the Crown to be held until the debt was satisfied by the rents and profits accruing from it.
As the "principal kind of extent," extent in chief operated adversarially: the Crown moved directly against the debtor, distinguishing it from the derivative forms of extent (in aid and in the second degree) that arose from different procedural postures.
Common Confusion
EXTENT IN CHIEF / EXTENT IN AID / EXTENT IN THE SECOND DEGREE: These three forms of extent are closely related but arise in different circumstances. Extent in chief issues directly for the Crown's own debt. Extent in aid issues when a Crown debtor seeks to collect from his own debtors to satisfy his obligation to the Crown — essentially a secondary sweep. Extent in the second degree reaches yet another level removed. Researchers working in historical English practice records must identify which form is at issue, as the procedural posture and available defenses differed among them. Black's and Burrill's both define extent in chief as the "principal kind," implying the others are derivative and subordinate.
Why It Matters in Research
Extent in chief is a term encountered almost exclusively in historical English legal materials — primarily pre-nineteenth century common law practice sources, Exchequer records, and treatises on Crown proceedings. Researchers will not find this remedy in American law; it was a feature of the English fiscal prerogative and did not transplant to the former colonies in any operative sense.
Several navigational points for corpus researchers:
First, the writ belongs to the Exchequer jurisdiction. Primary materials will appear in Exchequer practice guides, not in common law pleading manuals organized around King's Bench or Common Pleas procedure. Tidd's Practice and Stephen's Commentaries are the anchoring secondary sources cited by both Black's and Burrill's, and both works treat extent in the context of Crown debt collection procedure specifically.
Second, the term "extent" alone appears frequently in older sources and can refer generically to any of the three forms. When a source says simply "extent," researchers must read context carefully to determine whether extent in chief, in aid, or in the second degree is meant. Cross-referencing the procedural posture of the case (Is the Crown the direct creditor? Is the debtor pursuing a sub-debtor?) will resolve ambiguity.
Third, the remedy was largely abolished by English statutory reform in the nineteenth century, culminating in the Crown Proceedings Act 1947, which placed the Crown on a largely equal footing with ordinary creditors. Post-1947 English materials will not reference this remedy as a live procedure. Any appearance after that date is historical reference or commentary.
Fourth, American researchers encountering this term in early federal materials — particularly in contexts involving debts owed to the United States government — should note that Congress enacted its own priority statutes governing the federal government's rights as a creditor, which operated on different theoretical foundations than the English prerogative writ. The conceptual kinship exists, but the procedural mechanism does not carry over directly.
Historical Dictionary Support
Black's and Burrill's are in complete agreement on the core definition, with both citing the same two sources: Stephen's Commentaries (4 Steph. Comm. 47) and Tidd's Practice (2 Tidd, Pr. 1045). The alignment is so close that Burrill's entry appears to derive from the same underlying text.
Neither dictionary elaborates on the mechanics of how the writ operated in practice — the appraisement process, the appointment of a receiver, or the debtor's remedies — leaving those details to the treatises they cite. Researchers who need procedural depth must go to Tidd directly. Neither entry addresses the historical abolition of the remedy or flags its obsolescence, which reflects the vintage of both dictionaries and underscores the importance of treating their definitions as snapshots of practice at a particular moment, not as statements of current law.
The brief note in Burrill's referencing "consolidating or uniting" (visible in the source text as a partially corrupted entry) appears to be typographic artifact from the original digitization and should not be read as substantive content.
Jurisdictional Note
Extent in chief was a remedy of English law rooted in the royal prerogative and administered through the Court of Exchequer. It has no direct counterpart in American federal or state law. Researchers working in comparative or historical contexts should treat this as an English common law term of art only.
