4 Cards On This Topic:

Marriage voidable if party was of unsound mind.

Unsoundness of mind required for nullity is inability to understand obligations assumed by marriage.

After death of a spouse, the validity of an allegedly voidable marriage cannot be subject to collateral attack in probate court on the ground of mental incapacity; voidable marriage is valid until annulled.

Voidable marriage may only be challenged prior to the death of one of the parties.
