Definition
A verbal contract, in classical civil law usage, was a specific category of obligatory agreement that required, beyond the mere consent of the parties, the performance of a solemn or prescribed form of words to bring the obligation into legal existence. The contract was not complete — and no enforceable duty arose — until the required verbal formality was observed. The two principal forms were stipulatio (stipulation), a formal question-and-answer exchange, and fidejussio (fidejussion), a form of suretyship undertaken by the same verbal method.
In modern common law usage, "verbal contract" has drifted significantly from this technical meaning and is now used loosely — and often inaccurately — as a synonym for an oral contract, meaning any agreement made by spoken words rather than written instrument.

Common Language
Modern common usage (Wiktionary): An agreement made using spoken words; commonly used as a synonym for "oral contract," as opposed to a written contract.
Historical common usage (Webster's 1913): "Verbal" is defined as expressed in words, spoken rather than written; oral.
The gap here is significant and directional. In common usage, "verbal" means spoken rather than written. In its precise civil law sense, "verbal contract" did not describe the medium of communication (spoken versus written) but rather a formal category defined by the ritual use of prescribed words. A verbal contract in the civil law tradition could theoretically be recorded; what made it "verbal" was the legal efficacy attached to the spoken formula itself, not the mere absence of a document. A researcher who reads "verbal contract" in a civil law source and interprets it as simply meaning "oral agreement" will fundamentally misread the source.

Common Confusion
"Verbal contract" and "oral contract" are treated as interchangeable in modern legal practice and in most contemporary American and English legal writing. This equivalence is practically entrenched and unlikely to cause confusion in modern sources. The danger runs in the opposite direction: researchers working in civil law materials, Roman law scholarship, or historical sources influenced by the civil law tradition will encounter "verbal contract" in its technical sense — a formality-dependent obligation — and must resist importing the modern oral/written distinction. The two meanings are not merely different; they describe categorically different legal concepts. Burrill's entry, drawing on Hallifax's Analysis of the Civil Law, is squarely in the classical tradition and uses the term in its technical sense throughout.

Why It Matters in Research
The central research trap with this term is chronological and jurisdictional. In the Law Mind corpus:
First, any source drawing on Roman or civil law — including treatises, encyclopedias, and historical analyses predating widespread common law codification — will use "verbal contract" in its technical sense. The obligatory formality, not the oral medium, is the defining characteristic. Misreading this will produce errors in understanding how obligations were classified and enforced in the civil law tradition.
Second, common law sources from the 19th century onward increasingly use "verbal contract" to mean oral contract, often in contrast to written or sealed instruments. The shift is gradual and not always acknowledged by the sources themselves. A treatise from 1840 may use the term in either sense depending on whether the author is writing in a common law or civil law register.
Third, the Statute of Frauds context is a particular hazard. Modern discussions of "verbal contracts" as unenforceable without a writing are operating entirely within the common law oral/written framework and have no connection to the civil law category. Conflating these discussions with civil law sources will generate false parallels.
Fourth, researchers following a thread from verbal contracts into evidence law should note the related but distinct concept of the "verbal act" — spoken words that have independent legal significance, treated as operative facts rather than assertions. The Law Mind encyclopedia entry linked above addresses this evidence doctrine directly. The terminological overlap (both involve legally significant words) can create false cross-references if the researcher is not alert to the distinction.

Historical Dictionary Support
Burrill's Law Dictionary correctly locates "verbal contracts" within the civil law tradition and identifies the two principal species: stipulation and fidejussion. His definition follows Hallifax's Analysis of the Civil Law closely, which is an appropriate and reliable source for this category. The cross-reference to Justinian's Institutes (Inst. 3.16, De verborum obligationibus) grounds the definition in primary authority.
What Burrill does not address — and what is invisible from his entry — is the modern common law drift of the term toward "oral contract." His silence on this point reflects his focus on technical legal vocabulary rather than vernacular usage, but it means researchers using Burrill as a guide will receive no warning about the semantic divergence they will encounter in non-civil-law sources. Burrill's entry is useful precisely as an anchor for the technical meaning; it should be read alongside common law contract treatises of the same era to appreciate how far the terminology had already begun to diverge in practice.
