Definition
A Latin maxim meaning "according to the covenant" or "in accordance with the agreement." Used in legal instruments and pleadings to indicate that an act, performance, or obligation was carried out in conformity with the terms of an existing agreement or covenant. The phrase functions as a shorthand attestation that conduct conforms to what was contractually stipulated.
Why It Matters in Research
This term appears almost exclusively in historical legal materials — medieval and early modern pleading, conveyancing instruments, and Latin-form writs. Researchers encountering it in primary sources should treat it as a signal that the document is framing compliance or performance within a covenant framework, not merely asserting general lawfulness of conduct.
The phrase is closely tied to the pleading culture that required explicit Latin formulas to establish procedural posture. In that context, juxta conventionem was not descriptive filler; it was the operative phrase linking the act to the binding agreement and was necessary to ground a claim or defense in covenant rather than in some other form of obligation. Researchers working in early common law pleading records, particularly those involving debt, covenant actions, or conveyances, will encounter the phrase in precisely this structural role.
Because both historical dictionary entries cite exclusively to Fleta (lib. 4, c. 16, § 6) — a thirteenth-century English legal treatise — researchers should understand that this term's documented usage anchors firmly in medieval English law. It does not carry significant independent doctrinal weight in modern common law, and it is effectively absent from contemporary legal usage. Any appearance in post-eighteenth-century materials is almost certainly either a quotation from or a deliberate allusion to older practice.
Corpus researchers should note the term is sparse even within historical dictionaries — both Black's and Bouvier's treat it as a simple two-word gloss rather than a developed doctrinal concept — which suggests it was never a term of art requiring extended treatment but rather a formula whose meaning was assumed to be self-evident to trained practitioners.
Historical Dictionary Support
Black's Law Dictionary and Bouvier's Law Dictionary are in complete agreement on this term, both rendering it as "according to the covenant" and both citing the same single source: Fleta, lib. 4, c. 16, § 6. Neither dictionary elaborates beyond the bare translation and citation. This uniformity reflects the term's status as a transparent Latin phrase rather than a contested legal concept — the dictionaries treat it as needing identification, not interpretation.
The sole citation to Fleta is notable. Fleta is a late thirteenth-century Latin treatise on English common law, thought to have been composed by a lawyer or judge writing from the Fleet Prison (hence the name). Its fourth book addresses procedural and pleading matters. The citation anchors juxta conventionem specifically in the pleading tradition of medieval England, where Latin phrases carried formal legal significance and were not interchangeable with vernacular equivalents.
Neither dictionary source addresses how the phrase interacts with the broader doctrinal history of covenant as a form of action, or how it relates to the evolution of contract law. Researchers needing that context must look beyond the dictionary entries themselves.
