(a) A marriage may be declared void from the beginning at the action of either party, for any of the causes specified in section 1 of this title and whether so declared or not shall be deemed and held to be void in any action or proceeding whatever in which the same may come in question. However, a marriage once declared to be valid by the judgment of a court having jurisdiction thereof, in an action for that purpose, can not afterwards be questioned for the same cause, directly or otherwise.
(b) A marriage shall not be declared void for any of the causes specified in section 2 of this title, except at the action or claim of the party laboring under the disability, or upon whom the force or fraud was imposed or practiced; nor at the action or claim of such party if it appears that the parties freely cohabited together as husband and wife after the party had arrived at legal age, acquired sufficient understanding, been restored to reason, freed from the force, or discovered the fraud, as the case may be.
