An absolutely null marriage nevertheless produces civil effects in favor of a party
                  who contracted in good faith for as long as that party remains in good faith. Such
                  a marriage is regarded as putative.
               
               However, when the cause of the nullity is one party's prior undissolved marriage,
                  the civil effects continue in favor of the other party, regardless of whether the
                  latter remains in good faith, until the putative marriage is pronounced null or the
                  latter party contracts a valid marriage.
               
               A putative marriage may be established in Louisiana under the above conditions to
                  give the status of husband or wife to a person who applies for benefits as the spouse
                  of an insured on or after 1/1/88, or to give the status of widow or widower to a person
                  who applies for benefits as a surviving spouse of an insured who died on or after
                  1/1/88.
