Definition
Exactor regis is a Latin legal term meaning "the king's collector" or, more fully, "the king's exactor." In historical English law, it referred to an officer charged with collecting taxes, revenues, or other financial obligations owed to the Crown. The term was also applied, with some breadth, to the sheriff — an officer who exercised both enforcement and revenue-collection functions on behalf of the monarch within a given county.
Why It Matters in Research
Researchers encountering exactor regis in historical sources should be alert to the dual usage Black's identifies: the term could denote a dedicated tax collector or a sheriff acting in his revenue-collection capacity. These were not always the same officer, and context matters for understanding which function is at issue in a given document.
The term belongs to the dense vocabulary of medieval and early modern English fiscal administration, where Latin titles were used to describe royal officers whose exact duties shifted over time and varied by locality. In early sources, the exactor could be a relatively informal designee; in later administrative usage, the role became more structured within the apparatus of royal revenue. Researchers working in plea rolls, exchequer records, or county records from the Norman period through the early modern era may encounter the term across different documentary contexts with somewhat different institutional meanings.
Because the sheriff in English law was historically the primary royal officer at the county level — collecting amercements, fines, and other royal dues — the overlap between exactor regis and sheriff is not accidental. The two roles converged functionally in the person of the sheriff even when they remained technically distinct in administrative theory. Researchers should not assume that every instance of exactor regis signals a specialist tax officer distinct from the sheriff; the local officer of the Crown often wore both hats.
No direct American common-law successor to this office exists under that name. The Black's entry references Rev. St. in a fragment that appears to concern a related but distinct proceeding touching examination of a party's property — a reference that in context likely concerns American statutory provisions on examination of judgment debtors, not the exactor regis as an office. Researchers should treat that passage as a truncated entry artifact rather than a substantive American analog.
Historical Dictionary Support
Black's Law Dictionary provides the only historical legal dictionary treatment available in the Law Mind corpus. The entry is brief and fragmentary, offering two definitions — tax collector and sheriff — without elaborating on how the distinction was drawn or how usage evolved. The surviving text of the entry appears to be garbled by a page-break or editorial truncation, with the second sentence shifting abruptly to what may be a cross-reference to American statutory procedure unrelated to the term's primary historical meaning.
Historical sources beyond Black's would include Spelman's Glossarium Archaeologicum and Du Cange's Glossarium Mediae et Infimae Latinitatis, both of which address the vocabulary of medieval royal administration more fully. Researchers needing authoritative treatment of the term in its original administrative context should consult those works alongside the standard treatments of English fiscal history.
Jurisdictional Note
Exactor regis is a term of English legal history with no direct operational counterpart in American law. It appears in American legal dictionaries as a historical reference only. Research utility is primarily confined to English legal and administrative history, exchequer and chancery records, and the study of medieval and early modern royal administration.
