Definition
In Roman law, a person who had previously held the office of quaestor. The term denotes a former or ex-quaestor — an official who had completed service in one of Rome's foundational financial and administrative magistracies. The title appears most prominently as applied to Tribonian, the distinguished jurist and legal scholar who served under Emperor Justinian I and is credited with overseeing the compilation of the Corpus Juris Civilis, including the Institutes.

Why It Matters in Research
This term is a narrow historical marker with almost no practical research application outside Roman law scholarship or the study of Justinianic sources. Its primary significance is the single institutional reference it anchors: the identification of Tribonian in the preface to the Institutes (Inst. proem. § 3), where he is identified by this honorific to signal his former quaestorial rank and thus his authority in the compilation project.
Researchers working with the Corpus Juris Civilis or its reception history may encounter the term in Latin-language editions or commentaries on the Institutes. Because the term appears only in the ablative case (exquaestore) in surviving sources, it will not appear in nominative or other case forms — a practical trap for researchers conducting word searches in digitized Latin texts. Variant spellings and transcription errors (including the form "exquzstor" as a corrupted rendering) may appear in older printed editions or early digitizations of Roman law materials, making the term easy to overlook or misread.
The term has no living legal meaning, no statutory or common law context, and no jurisdictional variation relevant to modern practice. It belongs entirely to the historical vocabulary of Roman public law and the institutional biography of Justinian's codification effort.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) provides the only historical legal dictionary entry for this term, and it is brief: the term identifies one who had filled the office of quaestor, notes its application as a title given to Tribonian, cites the Institutes preface (Inst. proem. § 3), and flags the grammatical limitation that the term is used only in the ablative case. Black's does not elaborate on the quaestorship itself or the significance of Tribonian's role.
No broader historical dictionary treatment is available in the Law Mind corpus. Given the term's extreme specificity — a single honorific applied in a single classical source — the absence of richer dictionary support is unsurprising. Researchers needing fuller treatment of the quaestorship as an institution, or of Tribonian's role in Roman legal history, will need to look beyond legal dictionaries to classical scholarship and Romanist legal history.
