Definition
The act of swearing an oath, or the administration of an oath to another. Juration refers to the formal act itself — the solemn declaration invoking a higher power or truth as a witness — rather than the content of the oath or the instrument recording it. It encompasses both the perspective of the person administering the oath and the person taking it. In judicial and quasi-judicial contexts, juration is the procedural moment that transforms an ordinary statement into sworn testimony, a witnessed affidavit, or a legally cognizable declaration.
Common Language
Modern common usage (Wiktionary): "The process or act of making an oath."
Historical common usage (Webster's 1913): Not separately listed; the term was considered specialized legal vocabulary with no distinct common meaning in general dictionaries of the period.
The common and legal meanings here are functionally identical, but the legal context adds weight: juration is not merely the personal act of promising but a formal legal event with procedural and evidentiary consequences. When a person takes an oath in legal proceedings, juration is what makes the statement subject to perjury law and what renders testimony admissible as sworn evidence.
Common Confusion
Juration is sometimes conflated with the jurat — the certification clause at the foot of an affidavit recording when, where, and before whom the oath was administered. They are related but distinct: juration is the act; the jurat is the written evidence that the act occurred. Researchers working with historical affidavits and depositions should not treat the presence or absence of a jurat clause as equivalent to the presence or absence of juration — the oath may have been administered even if the certifying language is irregular or abbreviated.
Juration should also be distinguished from affirmation. An affirmation carries the same legal force as an oath but omits the invocation of a deity, available as an alternative for those with religious or conscientious objections. Historically, some sources use juration loosely to cover both; others restrict it to oath-taking strictly defined.
Why It Matters in Research
Juration appears infrequently in modern legal writing, where oath, sworn statement, and affirmation have largely displaced it. Researchers encountering the term in historical materials — particularly 17th through 19th century English and American legal texts, pleadings, and treatises — should recognize it as the procedural predicate for a range of downstream legal consequences: perjury liability, evidentiary weight of testimony, validity of affidavits, and competency of witnesses.
The maxim embedded in both Black's editions — Jurato creditur in judicio (he who makes oath is to be believed in judgment) — reflects a historical presumption in favor of sworn statements that has since eroded substantially. Modern evidence law treats sworn testimony as entitled to no automatic credibility boost beyond the baseline; the maxim is a historical artifact useful for understanding how courts once weighed competing declarations.
Corpus researchers should watch for juration in the context of compurgation, the medieval practice of oath-helping in which a party would produce oath-helpers (juratores or compurgators) to swear to the truth of the principal's claim. Rapalje & Lawrence links juration directly to jurator and compurgator, signaling that the term appears in texts dealing with early common law procedure where the distinction between fact-finding by jury and fact-finding by oath was still in formation.
Jurisdictional variation in historical sources matters here. Scottish law developed a distinct concept — juratory caution — involving a sworn undertaking to perform an obligation in lieu of a bond or surety. Researchers in Scottish legal records will encounter juration-family terminology in security and obligation contexts that have no direct English common law counterpart.
Historical Dictionary Support
Black's first and second editions are in complete agreement: juration is the act of swearing or the administration of an oath, defined identically across both. The stability of the definition across editions reflects that the term never generated doctrinal controversy — its meaning was settled and narrow.
Rapalje & Lawrence adds useful texture by placing juration within a cluster of related terms: jurator (a juror or compurgator) and juratory caution (the Scottish security concept). This clustering is editorially significant. By linking juration to jurator, Rapalje & Lawrence gestures toward the term's historical role in oath-based fact-finding — a procedural world in which juries themselves were, in origin, bodies of oath-takers rather than passive finders of fact.
None of the source dictionaries address the question of affirmation as a substitute for juration, nor do they discuss what procedural defects in juration might render a sworn statement void or voidable — gaps that became more practically significant as affirmation statutes developed in the 18th and 19th centuries.
Jurisdictional Note
In Scottish law, juratory caution is a recognized form of security — a sworn undertaking to satisfy a debt or perform an obligation — distinct from cautionary obligations backed by bond or surety. Researchers in Scottish court records and Scots private law sources should treat juration-family terms as potentially carrying this security-law meaning rather than the purely testimonial one familiar in English and American practice.
