Negative declaration (suit for jactitation of marriage)..

Any declaration as to status where one party alleges marriage and other denies, it would amount to a decree for jactitation of marriage. A suit for affirmative declaration about existing or subsisting of marriage is as much as a suit relating marriage as a suit fr negative declaration....there seems no reason why a suit for jactitation of marriage will not include a suit for declaration by a person falsely posing that he is the spouse of defendant.
