Evidence contained in the claims file indicates -that the claimant, Vickie L. S~,
                  and the wage earner, Harvey S~, underwent a civil marriage ceremony in Sonora, Mexico,
                  on November 25, 1968. The claimant was fifteen years old at the time; the wage earner
                  was '43. The marriage was consented to and witnessed by the claimant's mother, Dorothy
                  N~ .1_/ You have requested our opinion as to whether or not this marriage is valid,
                  void, or voidable under the laws of the state of Sonora. In order for us to fulfill
                  your request, it was necessary to consult the Law Library of the Library of Congress.
                  The following discussion is based primarily upon information provided to us by the
                  Library.
               
               Pursuant to Article 242 of the Sonora Civil Code, 2_/ a person between 14 and 20 years
                  of age (inclusive) must obtain the prior consent of both parents before contracting
                  a marriage.3/ Evidently, in this case the claimant's father did not consent to the
                  marriage. The lack of paternal consent constituted an impediment to the marriage and
                  provided grounds for its nullification. See Articles 248 and 393, Section II, of the
                  Civil Code. The marriage, however, was voidable, not void. A duly registered marriage
                  is presumed to be valid unless actually nullified by a final court judgment. Article
                  412. A petition for nullification. could have been filed by the claimant at any time
                  before she reached the age of 21. Article 395. It appears from the file that the claimant
                  did not petition for nullification prior to her twenty-first birthday. In addition,
                  her father could petition to nullify the marriage within thirty days of the time he
                  learned of the marriage, unless he expressly or tacitly' consented to the marriage
                  within that thirty-day term. Article 396. The claims file does not reveal when or
                  if Mr. E~ learned of the marriage. If he has never learned of it, the thirty-day period
                  has not yet commenced, and it would be conceivable that he might petition to annul
                  the marriage. Unless and until he does so, how- ever, the marriage between the claimant
                  and the wage earner is presumptively valid under the laws of Sonora.4_/
               
               1_/ Apparently Ms. N~ later changed her name to Dorothy D~.
               2/' Codigo Civil para el E.L.Y.S. de Sonora, Ed. Cajica, Puebla, 1977 (effective September
                  1949). All references contained in this opinion are to this code.
               
               3/ If one parent is deceased, the consent of the surviving parent is sufficient. The
                  claimant's marriage certificate lists her father, Kamimur E~, as “retirado” (retired).
                  Accordingly, we have presumed that he was alive on the date of the marriage ceremony.
                  If Mr. E~ was not alive, the consent of the claimant's mother was adequate to render
                  the marriage valid from the outset.
               
               4/ Because the claimant was at least 14 years old at the time of the ceremony, the
                  fact that she falsely stated her age as 18 would not be cause for invalidating the
                  marriage, as long as she had the requisite parental consent. (See text for rules applicable
                  to such consent.)
