What is a Suit to Declare Marriage Void?
Similar to an annulment, a marriage may be declared void if: the parties are too closely related to one another (ancestor or descendant by blood or adoption; brother and sister of whole blood, half blood, or adoption; uncle/aunt by whole blood, half blood or adoption; a first cousin by whole blood, half blood, or adoption) bigamy (one of the parties married at time of this marriage).
