Definition
A Latin legal term meaning "built of brick" or "made by burning." In legal usage, *coctilis* most commonly appears in the phrase *murus coctilis* — a brick wall — describing a structure made from fired (kiln-baked) materials as distinguished from walls built of stone, timber, or unburned earth.
The term was relevant in property and boundary disputes where the physical character of a wall or enclosure carried legal consequence — for instance, in determining whether a structure satisfied a legal requirement, defined a boundary, or constituted a sufficient enclosure or party wall.
Why It Matters in Research
Researchers are most likely to encounter *coctilis* in early English case law and pleadings where Latin descriptive terms were standard. Its appearance in Dyer's Reports (a sixteenth-century English law reporter) places it squarely in the period of Law French and Law Latin pleading, when physical descriptions of structures in disputes over land, nuisance, or boundaries were recorded in Latin rather than English.
The practical trap: a researcher scanning property or boundary litigation from the Tudor or early Stuart period may encounter *coctilis* as a descriptor without recognizing it as a term of art. It is not a legal doctrine in itself but a precise physical description that could bear on the legal classification of the structure at issue — whether it was permanent, whether it satisfied local building requirements, or whether it constituted an adequate enclosure under applicable customs or statutes.
Because the term is architectural-descriptive rather than doctrinal, it will not appear in indexes to legal principles. Researchers should look for it in the body of pleadings, in early reporters, or in conveyancing instruments describing premises. Its presence signals a dispute or description turning on the material composition of a wall or building.
Historical Dictionary Support
Burrill's Law Dictionary is the sole shelf source to record this term, defining it tersely as "Built of brick. Murus coctilis; a brick wall," with a citation to Dyer 108. The entry is characteristic of Burrill's treatment of Latin descriptive terms: minimal commentary, a gloss, and a reporter citation to demonstrate usage.
No other standard historical legal dictionaries in the Law Mind corpus — not Bouvier, Black, or Tomlin — appear to have carried this term, which reflects how narrow its practical currency was even in the era of Latin pleading. Its survival in Burrill reflects that dictionary's thoroughness in cataloguing Law Latin vocabulary drawn from the reports, rather than any broad doctrinal significance the term held.
The Dyer citation (108) points to James Dyer's *Reports*, covering cases from the reigns of Henry VIII through Elizabeth I — a primary source for mid-Tudor common law pleading and property law. Researchers consulting that report will find *coctilis* in its original procedural and descriptive context.
Jurisdictional Note
The term is native to English legal practice during the period of Latin pleading. It has no recognized counterpart or distinct usage in American legal sources, where Latin pleading forms were abandoned early. It is of historical relevance only in the English common law tradition.
