An action for a declaration of nullity of marriage for any cause cannot be maintained by parties to the marriage, or by the relations whose consent was necessary, when such marriage has been ratified or confirmed knowingly by those whose consent was necessary, or after a year has passed since they acquired knowledge of the cause for an action without any application to the courts for relief. Every marriage which has not been contracted publicly, and has not been celebrated before a competent public official, can be impugned by the parties themselves, by their fathers and mothers, by the ascendants, and by all who have an existing vested interest, as well as by the Public Prosecutor. No one can legally claim the status of husband or wife, or the effects and privileges resulting by law from marriage, without the production of a certificate of the marriage celebration, except in the cases provided for by Article 46 of the code, namely, when no records have ever existed, or the same have been lost or destroyed. In such cases the marriage may be established by oral evidence. The fact that by common repute the parties are married does not dispense with the necessity of producing the record of the celebration. However, if there are children born of two persons who have lived openly as husband ind wife, and who are both dead, the legitimacy of their children cannot be assailed on the sole ground that a record of their parents' marriage is not produced. A marriage which has been declared a nullity has, if contracted in good faith, the civil effects of a marriage so far as the parties themselves and their children are concerned. If only one of the parties has acted in good faith the legal consequences of marriage only exist in favour of the innocent party and of the children of the marriage. The last two paragraphs, which are virtually a translation of Articles 201 and 202 of the Civil Code, are very important to foreigners who marry French citizens. Until a court has pronounced the marriage a nullity the marriage between a French citizen and a foreigner celebrated abroad is binding upon the parties, even though the exacting forms required by the French law have not been complied with. If an Englishwoman in good faith marries a Frenchman in London she is entitled by French law to the civil rights of a wife, and her children the issue of the marriage would be considered legitimate, although the marriage had not been celebrated after the publication of banns in the manner prescribed by the code; or the record of such celebration transcribed within three months of the return of the French husband to France. The foreign wife would have the same rights even if she married a Frenchman under twenty-five years of age without the previous consent of his parents. Of course, such a marriage could be declared null, leaving both parties free to marry again.
