Definition
Jactitation of marriage is a doctrine of English ecclesiastical law under which a person who falsely and publicly boasts or declares that he or she is married to another may be compelled by a court to cease making that claim. The false assertion, if left unchallenged, risked creating a common reputation of marriage between the parties — a reputational harm that courts of ecclesiastical jurisdiction were empowered to remedy.
The injured party could bring a libel (a formal complaint) before an ecclesiastical court. If the boasting party could not prove an actual marriage, the court would impose silence — ordering the offender to stop asserting the marriage and, in effect, publicly repudiating the false claim.
For the action to lie, the boast had to be both false and malicious. A genuinely mistaken claim, or one made without the intent to injure reputation, did not satisfy the requirements of the cause of action.

Common Confusion
Jactitation of marriage should not be confused with a suit to declare a marriage void or with a nullity proceeding. Nullity assumes a marriage ceremony occurred and asks whether it was legally valid. Jactitation assumes no valid marriage exists and asks only that a false public claim to one be suppressed. The relief is remedial and reputational, not a determination of marital status in the ordinary sense. Researchers who encounter jactitation in historical ecclesiastical records should resist mapping it onto modern declaratory judgment actions concerning marriage — the conceptual fit is imprecise.

Why It Matters in Research
This term belongs almost entirely to the historical record. Jactitation of marriage was a live cause of action in the English ecclesiastical courts before jurisdiction over matrimonial causes was transferred to civil courts by the Matrimonial Causes Act 1857. After that transfer, the action survived briefly in the new Divorce Court but fell into disuse. American courts never adopted it in any systematic way, and it does not appear as a functioning cause of action in any contemporary U.S. jurisdiction.
Researchers working in pre-1857 English ecclesiastical court records — particularly the records of the Consistory Courts and the Court of Arches — will encounter jactitation proceedings alongside other matrimonial causes such as suits for restitution of conjugal rights and nullity actions. Understanding that jactitation was classified as one of the principal matrimonial causes (Burrill makes this point explicitly) helps orient researchers within the taxonomy of ecclesiastical jurisdiction.
The key navigational trap: because jactitation rests on reputation rather than ceremony or cohabitation, it intersects with the now-abolished doctrine of common law marriage by repute. Researchers tracing the history of informal marriage recognition should be alert to jactitation proceedings as evidence of how seriously courts treated the reputational dimension of marital status — and as a counterweight to doctrines that allowed reputation itself to constitute marriage. The connection to marriage by estoppel (see Encyclopedia cross-reference above) is conceptually live: jactitation punished the creation of a false marital reputation, while estoppel could bind a party to a claimed marital status.
Corpus researchers should also note that "jactitation" as a standalone term appears in at least one other ecclesiastical context — jactitation of tithes, referring to a false claim of entitlement to tithes — so search strings limited to the word "jactitation" alone may return irrelevant results. Search for the full phrase.

Historical Dictionary Support
Black's, Bouvier's, and Burrill's agree on the core definition: a false public boast of being married to another, actionable because it could generate a common reputation of marriage. All three cite 3 Blackstone's Commentaries 93 as the primary authority, and none depart from Blackstone's framing in any material way.
Bouvier adds the most legally significant detail: the boast had to be malicious as well as false, citing Haggard's Ecclesiastical Reports for the proposition. This mens rea-adjacent requirement distinguished jactitation from innocent misstatement and reflects the ecclesiastical courts' attention to culpability even in what modern lawyers might consider a purely civil remedy.
Burrill is notable for its characterization of jactitation as "one of the first and principal of what are termed matrimonial causes" — a taxonomy that usefully situates the action within the broader structure of ecclesiastical jurisdiction over marriage. None of the three dictionaries address the post-1857 fate of the doctrine or its absence from American law, which is a significant gap for any researcher expecting the dictionary entries alone to tell the full story.

Jurisdictional Note
Jactitation of marriage is an English ecclesiastical law doctrine with no meaningful parallel in American statutory or common law. Researchers working in U.S. sources will not find operative jactitation proceedings; the concept surfaces in American legal dictionaries as historical background only. In England and Wales, the action is effectively extinct.
