jactitation of marriage. Hist.
1. False and actionable boasting or claiming that one is married to another.
2. An action against a person who falsely boasts of being married to the complainant.
“Jactitation of marriage is a cause of action which arises when a person falsely alleges that he or she is married to the petitioner, and the remedy sought is a perpetual injunction against the respondent to cease making such allegations. The cause is now uncommon in English municipal law and almost unknown in the conflict of laws.” R.H. Graveson, Conflict of Laws 349 (7th ed. 1974).
