Definition
Green wax is a historical English legal term referring to the estreats of fines, issues, and amercements extracted from the Exchequer and delivered to the sheriff of each county for collection. The name derives from the green wax used to impress the seal of the Exchequer court upon these documents, distinguishing them from instruments sealed in the ordinary manner.
In practice, an estreat was a certified extract from the court's rolls, confirming the amounts owed to the Crown by way of fines, forfeited recognizances, and amercements. Once extracted and sealed in green wax, these documents were sent out to the sheriffs, who were then responsible for levying and collecting the sums within their respective counties. The green wax thus represented both the document itself and the process of Exchequer-directed collection that it authorized.
The term appears in English statutes from at least the reign of Edward III and continued in use through the subsequent centuries of Exchequer practice. It belongs entirely to the historical administrative and fiscal machinery of the English Crown and has no surviving operative legal meaning.

Common Language
Modern common usage (Wiktionary): An estreat from the Exchequer, delivered to a sheriff, sealed upon green wax, in 15th-century England.
Historical common usage (Webster's 1913): Not entered. The term did not circulate in ordinary English usage.
The Wiktionary definition is serviceable but narrow. Green wax was not limited to the 15th century — it appears in statute as early as 42 Edward III (1368) and continued well beyond that period. The term also refers more precisely to the category of documents and the collection mechanism they represented, not merely to the physical object or a single era.

Why It Matters in Research
Researchers encountering green wax in historical sources should understand several navigational points.
First, the term functions as shorthand for the entire Exchequer estreat process — not just the document, but the duty it imposed on the sheriff and the revenue enforcement framework behind it. A reference to green wax in a plea roll, statute, or legal treatise is almost certainly touching on Crown revenue collection or the liability of a party for an unpaid fine or amercement.
Second, the statutory anchor is real and traceable. Burrill cites Statute 42 Edward III, c. 9, and Statute 7 Henry — researchers working in the period statutes or their commentaries will find green wax appearing in that fiscal legislative context. Be alert that statutory citations in the historical dictionaries are sometimes truncated; verify regnal year and chapter against primary sources.
Third, the term has no modern survival. It does not appear in contemporary common law jurisdictions as an operative concept. If green wax surfaces in a modern document, it is either historical quotation, antiquarian reference, or a sign the document itself is historical in nature. Do not attempt to map it onto any current court collection or enforcement procedure.
Fourth, the connection between estreats generally and green wax specifically is important to keep clear. Estreats existed in many contexts; green wax estreats were specifically those originating in the Exchequer and sealed with the distinctive green wax seal. Researchers should not assume that every reference to estreats in historical sources implies green wax, or vice versa.

Historical Dictionary Support
The dictionary sources are in close agreement on the core definition, which reflects the stable, narrow meaning of a term firmly rooted in a specific institutional context.
Black's Law Dictionary (1st ed.) provides only a fragment — the entry appears to have been cut off in the source material — but the surviving text confirms the Exchequer and sheriff framework. The Second Edition of Black's adds the detail that the seal was "impressed upon green wax," clarifying that the wax color was the distinguishing physical feature of the seal itself, not merely the color of the document.
Bouvier's Language is clear and complete: estreats of fines, issues, and amercements, delivered to the sheriff under the Exchequer's green-wax seal. Burrill is the most historically detailed, citing specific statutory authority (42 Edw. III, c. 9) and using the Latin form viridis cera, which is useful for researchers working in Latin legal sources of the medieval and early modern period.
No significant divergence exists among the sources. What the historical dictionaries do not address — and where researchers should exercise caution — is the procedural relationship between the issuance of green wax and the actual mechanics of sheriff enforcement: what happened when a sheriff failed to collect, how disputes about the underlying liability were handled, and how the process evolved or was reformed in later Exchequer practice. For those questions, the dictionaries are a starting point only.

Jurisdictional Note
Green wax is exclusively an institution of English law, rooted in the Exchequer court system. It has no counterpart in Scots law, colonial American practice, or any modern common law jurisdiction. Researchers in Irish or Welsh historical legal records may encounter references derived from the same English Exchequer apparatus, but should verify the specific institutional context before assuming identical meaning.
