Definition
A Latin term from old English legal practice meaning "return." RETORNUM appears in medieval procedural law as the formal designation for the return of a writ — the sheriff's or officer's written report back to the court certifying what action was taken in executing a writ issued to them. It is essentially the Latin root word underlying the broader procedural concept of the return, and appears in this sense in historical treatises on English common law procedure.
Why It Matters in Research
RETORNUM is a term researchers will encounter almost exclusively in pre-modern English legal sources — particularly treatises, Year Books, and Latin-language procedural manuals predating the systematic anglicization of common law terminology. Its significance in the Law Mind corpus is primarily as a Latin antecedent and variant form of the term "return" as used in writ practice. Researchers should be aware of several navigational points:
First, the term has no independent doctrinal life in modern law. Encountering RETORNUM in a source is a strong signal that the document is either pre-modern or is a treatise closely following medieval Latin forms. Dating the source accordingly will affect how much procedural weight to assign its surrounding context.
Second, because Anderson's Dictionary of Law entry excerpted in the source material appears to have been generated against the wrong headword — the text concerns the retirement of bills of exchange and indorsers, which is entirely unrelated to RETORNUM — researchers relying on Anderson's as a cross-reference for this term should treat that entry with caution. The editorial content does not correspond to the Latin term and appears to be a cross-reference or digitization artifact. Burrill's entry is the reliable source here.
Third, RETORNUM connects directly to a cluster of related writ-practice vocabulary — RETURNUM, HABEAS CORPUS, REPLEVIN, and the sheriff's return — that researchers working in English common law history or equity procedure will need to navigate together. The procedural concept of the return was one of the most consequential in pre-modern practice: a false or defective return could expose the sheriff to liability and affect the validity of proceedings built on the writ. Understanding RETORNUM as the Latin term for this concept helps decode citations in Bracton, Fleta, and Britton.
Fourth, RETORNUM appears in Fleta, Book II, specifically in the sections Burrill cites (lib. 2, c. 45, §§ 4, 7), which concern the duties of sheriffs and the mechanics of writ execution. Researchers consulting Fleta in the original Latin will encounter RETORNUM in precisely this context.
Historical Dictionary Support
Burrill's Law Dictionary gives the authoritative entry: "L. Lat. In old practice. Return; a return," with citation to Fleta. This is a tightly correct and complete entry for a term that requires little elaboration — RETORNUM is a functional label, not a doctrinal concept with contested edges. Burrill's citation to Fleta is reliable and points researchers to the correct primary source.
Anderson's Dictionary of Law, as noted above, does not provide a usable entry for this term as represented in the available source material. The excerpt concerns bills of exchange and retirement of negotiable instruments — a wholly separate legal domain. Researchers should not use Anderson's as authority for RETORNUM's meaning.
Historical legal dictionaries generally agree on the narrow, procedural meaning of this term. There is no meaningful divergence in the sources, and no known evolution of the term's meaning over time — its use was already archaic by the time modern legal dictionaries were compiled. What the historical dictionaries collectively miss is any explanation of the doctrinal context in which the sheriff's return operated and why it mattered, which requires recourse to treatises rather than dictionary entries alone.
Jurisdictional Note
RETORNUM is a term of English common law and has no independent meaning in American, Scottish, or civilian legal traditions. American courts and statutes use "return" in English, and the Latin form does not appear in operative modern legal documents in any common law jurisdiction.
