Definition
In Roman civil law, *stipulari* is the verb describing the act of making a stipulatio — the formal oral contract of Roman law in which one party (the stipulator) asks a question and the other party (the promisor) answers with a corresponding, unconditional affirmation. The term carries the specific sense of demanding or asking in the structured, ritualized manner required to give legal force to the transaction. It is the active verbal component of the stipulatio: to stipulate in the Roman sense is not merely to agree, but to solemnize agreement through the prescribed form of question and answer.
Because *stipulari* is a Latin term of art from the Roman civil law tradition, it does not appear in modern common-law statutory or case vocabulary as a standalone term. It functions in legal research primarily as a root concept and a technical label found in civil law treatises, Roman law scholarship, and comparative legal sources.
Common Language
Modern common usage (Wiktionary): To stipulate is to specify or demand as part of an agreement; to lay down as a condition.
Historical common usage (Webster's 1913): "To make an agreement or covenant with any person or company to do or forbear anything; to contract; to settle terms."
The gap is significant. In ordinary English, "stipulate" implies nothing more than specifying a term or condition — informally, in writing, in any form. The Latin *stipulari*, by contrast, describes a highly ritualized oral act that was the formal foundation of Roman contractual obligation. The question-and-answer form was not a nicety; it was the substance of the legal act. Without the proper verbal exchange, no stipulatio arose, and no enforceable obligation was created. Modern usage has retained the word while discarding every element that made it legally operative in its original context.
Common Confusion
*Stipulari* is the Latin verbal form; *stipulatio* is the noun designating the contract or transaction itself. These are frequently treated as interchangeable in secondary sources, but the distinction matters in technical reading: *stipulari* refers to the act of stipulating, while *stipulatio* refers to the legal instrument or obligation that results. Researchers encountering either term in translated Roman law texts or civil law treatises should be careful not to conflate the procedural act with the contractual form it produces.
The modern English verb "to stipulate" — meaning simply to specify a condition or requirement — descends from this root but has shed the formal procedural requirements entirely. See COMMON LANGUAGE below.
Why It Matters in Research
Researchers working in Roman law, civil law jurisdictions, or comparative legal history will encounter *stipulari* primarily in Latin texts and their translations, in civilian treatises drawing on Roman foundations (such as Justinian's Corpus Juris Civilis and its commentators), and in historical analyses of contract formation doctrine. Several practical points warrant attention:
First, the term marks a doctrinal boundary. When a historical source shifts from discussing *stipulari* or *stipulatio* to discussing consent-based contract theories, the researcher is tracking one of the most important transitions in Western contract law — from formalism to consensualism. Recognizing *stipulari* as a term of strict formalist obligation helps locate a source within that trajectory.
Second, the Burrill entry's fragment — "to ask or demand" — points to the essential asymmetry of the stipulatio: one party asks, one party answers. This is not a negotiated exchange in the modern sense. Research into early common-law forms of assumpsit and later consideration doctrine sometimes traces lineage through or contrast with the Roman stipulatio model; understanding *stipulari* as the asking-act clarifies why Roman jurists were preoccupied with the precision of the verbal formula.
Third, in Louisiana, Quebec, and other mixed or civilian jurisdictions, sources drawing on civil law tradition may invoke stipulatio concepts explicitly or implicitly. Researchers should not assume that modern civilian "stipulation" (e.g., stipulation pour autrui — the third-party beneficiary contract) maps cleanly onto *stipulari*; the modern civilian concept has evolved substantially from its Roman root.
Historical Dictionary Support
Burrill's Law Dictionary provides only a partial entry for *stipulari*, preserved here as: "Lat. In the civil law. In a strict sense, to ask or demand some—" — the entry appears truncated in the available source. The surviving fragment is nonetheless revealing. Burrill's framing of *stipulari* as carrying a "strict sense" of asking or demanding signals awareness that Roman jurists themselves debated the term's precise scope and that later usage had blurred its edges.
The broader Roman juristic tradition, as reflected in Justinian's Institutes and Digest, treated *stipulari* as the technical verb for the formal oral interrogation that initiated the stipulatio. Gaius in his Institutes describes the essential form: the stipulator asks, "Dari spondes?" ("Do you solemnly promise to give?"), and the promisor answers, "Spondeo" ("I solemnly promise"). Later classical and post-classical jurists relaxed the strict verbal requirement, eventually permitting written records to substitute as evidence of the oral exchange — a significant doctrinal softening that later civilian commentators tracked carefully.
Burrill, as a common-law lexicographer, does not situate *stipulari* within that evolution, which is a notable gap for research purposes. Civilians and Romanists will need to go beyond Burrill to Justinian's sources and to treatises such as those of Pothier, whose work on obligations bridges Roman and modern civil law and directly influenced both Louisiana and French civil law development.
Jurisdictional Note
*Stipulari* as a technical term is relevant primarily to Roman law scholarship and to jurisdictions with strong civilian roots, particularly Louisiana and Quebec. In those jurisdictions, courts and treatises may reference the Roman stipulatio tradition when interpreting modern contract formation rules, third-party beneficiary doctrine, or the requirements for formal contracts. Common-law jurisdictions have no operative use for the term, though comparative contract law scholarship invokes it frequently.
