Definition
In old legal practice, serrated describes a document edge cut or notched in a jagged, saw-tooth pattern. The term appears most often in the context of deeds of indenture, where the physical serration of a document's top edge served as an authentication device: an original deed was written in duplicate (or more) on a single sheet, the copies then separated by cutting along a serrated or irregular line. Because no two cuts produce an identical edge, the matching of the two halves confirmed the document's authenticity and prevented forgery or substitution. The term is not used to describe a substantive legal right or obligation but rather a formal characteristic of a class of legal instruments.
Common Language
Modern common usage (Wiktionary): Notched or cut like a saw; having a row of sharp or tooth-like projections. Applied broadly to knives, leaves, edges, and any object with a toothed margin.
Historical common usage (Webster's 1913): "Having notches like the teeth of a saw; as, a serrated leaf."
The common meaning and the legal meaning are not in conflict, but the gap is contextual: in ordinary English, serrated describes a physical property of any object. In legal usage, the term carries a specific functional and evidentiary purpose — the serrated edge of an indenture was not incidental to its shape but was the mechanism by which the instrument's integrity was guaranteed. Understanding the legal context transforms a descriptive adjective into a term of art tied to the authentication of deeds.
Common Confusion
Serrated and indented are sometimes treated as interchangeable in both historical and modern discussion of old deeds, but they are not synonyms. Indented (and the instrument called an indenture) is the broader legal term describing the practice and the resulting document. Serrated is a physical descriptor — the specific character of the cut edge. An indenture was serrated; the serration is what made it an indenture. Researchers encountering either term in historical documents should consult the entry for INDENTURE and the entry for INDENT (v.) to understand the full legal significance of the practice.
Why It Matters in Research
Researchers will encounter serrated almost exclusively in two contexts: historical discussions of deed authentication and descriptive passages about the physical form of early English legal instruments. The term rarely appears as a legal operative word in its own right; it appears as explanation.
Two research traps are worth flagging. First, serrated in modern legal contexts — particularly criminal law and products liability — refers to the blade characteristic of certain knives and tools, carrying no connection to documentary practice. A full-text corpus search across eras will return results from both worlds, and anachronistic readings run in both directions. Second, the historical dictionary entries for this term are immediately followed in both Black's editions by unrelated entries (SERVAGE, SERVANDA), reflecting the alphabetical proximity of Latin-rooted terms. Researchers scanning page images or transcriptions should verify that surrounding context belongs to the correct entry.
The connection to Roman coinage noted in Burrill — where serrated edges on coins served a similar anti-forgery function — is a useful comparative note when researching the intellectual history of document authentication, though it has no direct legal authority.
For corpus researchers tracing the history of deed formalities in English law, this entry is a navigational waypoint toward the more substantive entries on INDENTURE, INDENT, and DEED.
Historical Dictionary Support
The three source dictionaries agree on the core definition without meaningful variation. Black's (both editions) defines serrated as "notched on the edge; cut in notches like the teeth of a saw" and directs readers to INDENT. Burrill adds the most texture, noting the Latin root (serratus, from serra, a saw), the Roman coin parallel drawn from Tacitus, and the explicit connection to indenture practice as a precaution against forgery.
What the historical dictionaries do not address: the term's later migration into criminal law and regulatory contexts, where serrated describes blade characteristics in weapons statutes and similar instruments. This is an expected gap — the dictionaries reflect the law of their era — but it means historical dictionary entries for this term are incomplete guides for researchers working across time periods.
