Jactitation of marriage is a legal term in matrimonial law that pertains to a false claim of marriage made by one party to the detriment of another. In essence, it involves the public assertion of a marital relationship that does not exist, causing confusion and potential harm to the reputation or interests of the falsely claimed spouse. This concept is essential in legal systems to prevent deceptive claims of marriage, protecting individuals from unwarranted associations or obligations. Courts often address jactitation of marriage cases by seeking to establish the truth of the alleged marriage and, if necessary, issuing orders to rectify any false claims, thereby preserving the integrity of matrimonial law.
