Definition
In Roman law, an adotipulator was a secondary or accessory party to a stipulatio (a formal verbal contract) who received the same promise as the principal stipulator. The adotipulator held an independent right to demand and receive performance of the promise — including after the death of the principal party. The role functioned as a kind of parallel creditor, providing security and continuity to a contractual obligation by ensuring that the promise could be enforced even when the primary promisee was no longer available.
The term appears exclusively in the context of classical Roman contract law and has no living application in modern common law or civil law systems as a recognized legal category.
Common Confusion
ADOTIPULATOR vs. STIPULATOR: These are related but distinct roles. The stipulator is the principal party who poses the formal question and receives the promise in a stipulatio. The adotipulator is the accessory party who is joined to that same transaction and acquires a co-equal or parallel right of enforcement. The distinction matters in historical research: sources referencing a stipulator are not necessarily referencing the adotipulator, and conflating the two obscures the bilateral-creditor structure of certain Roman obligations.
ADOTIPULATOR vs. ADSTIPULATOR: These terms refer to the same office. Adotipulator is an orthographic variant of adstipulator, the more commonly encountered form in Roman law scholarship. Researchers encountering either spelling in historical sources should treat them as equivalent. The variation reflects inconsistent transliteration and editorial choices across editions of Roman law texts rather than any difference in legal meaning.
Why It Matters in Research
This term will appear almost exclusively in sources dealing with classical Roman law, making it a narrow but occasionally important search term for researchers working in legal history, comparative law, or the Roman-law foundations of civil law systems.
Several navigational points for corpus researchers:
Spelling variation is the primary trap. Bouvier renders the term as adotipulator, but the dominant form in Roman law scholarship — including Sandars's Institutes and Hunter's Roman Law — is adstipulator. A search limited to one spelling will miss a significant portion of relevant material. When searching the Law Mind corpus, run searches for both forms as well as the root stipulator with relevant contextual terms.
The role is closely tied to the formal structure of stipulatio, the Roman oral contract requiring a question and answer in prescribed form. Understanding adotipulator requires understanding stipulatio first; researchers unfamiliar with that framework should orient there before pursuing this term.
The adotipulator's independent enforcement right upon the principal's death connects to broader Roman law concerns about contractual succession and the survival of obligations — themes that recur in civil law treatments of novation, delegation, and suretyship. Researchers tracing the genealogy of those modern concepts may find the adotipulator cited as an early mechanism for solving the problem of creditor incapacity.
The term does not appear in English common law sources, equity sources, or American legal materials except as historical reference. Its presence in Bouvier reflects that dictionary's sustained engagement with Roman law as background to American jurisprudence, not any direct transplantation of the concept.
Historical Dictionary Support
Bouvier's Law Dictionary provides the only dictionary-level definition available in the current corpus. The entry is brief and derivative, directing researchers to Sandars's Institutes (5th ed.) at page 348 and Hunter's Roman Law (2nd ed.) at page 563 for substantive treatment. Bouvier also cross-references Black's Law Dictionary, though no independent Black's entry is available in the present source set.
The Bouvier entry captures the essential functional point — that the adotipulator could receive and exact payment even after the principal's death — but it does not explain the mechanism by which this worked within Roman obligational theory, nor does it situate the role within the broader taxonomy of accessory parties to Roman contracts (which also included the adpromissor on the debtor's side). Researchers relying on Bouvier alone will have a definition but not an understanding of context.
Notable absence: no entry for adstipulator appears as a distinct headword in Bouvier's corpus entry, suggesting Bouvier treats the adotipulator form as the primary lemma. This is atypical relative to most Roman law scholarship, where adstipulator is standard. Researchers should not assume the spelling difference reflects a substantive distinction.
Jurisdictional Note
The adotipulator is a creature of classical Roman law and exists in modern legal research only as a historical concept. It has no current jurisdictional footprint in common law systems. Civil law systems derived from Roman law do not preserve this specific role, though its functional concerns are addressed through modern doctrines of joint creditorship and contractual assignment.
