Annulment in Missouri is applicable to two distinct categories of challenged marriages: Those that are void and those that are voidable. The distinction is that a void marriage is always a nullity, whereas a voidable marriage is valid until a judgment is entered declaring it void. The Court's of Missouri have declared a strong public policy in favor of marriage, and a presumption in favor of marriage which is one of the strongest presumptions under the law. This means that in order to get an annulment, the moving party must show "strong, distinct, satisfactory, and conclusive" evidence to support the claim. In the overwhelming majority of cases, dissolution is the appropriate method to dissolve the marriage rather than annulment.
