Foreigners desiring to be married in Italy must present a certificate from the competent authority of their own country that they satisfy the requirements of the laws of that country. Foreigners ordinarily residing in Italy must also satisfy the requirements of the Italian law. PRELIMINARIES.--The preliminary formalities to marriage are essentially the same in both the French and the Italian Codes. LEGAL OPPOSITION.--Legal opposition to the marriage may be made by the parents or, in want of them, by the grandparents of either party, if they are cognizant of the existence of any legal impediment, even if the parties are of age. In default of ascendants, opposition can also be made by a brother, sister, uncle, aunt, or cousin german, as well as by the guardian or curator duly authorized by the family council, on the ground of lack of the required consent or the infirmity of mind of one of the parties to the marriage. Anyone may oppose the remarriage of his former consort. The public prosecutor is required to oppose the marriage officially when he is cognizant of any impediment, and to facilitate his accomplishment of this duty the registrar is bound to inform him of any impediment that appears to exist. The effect of a legal opposition is to suspend the celebration of the marriage until the case has been determined in court. If the opposition proves to be without legal ground the one filing it, unless one of the ascendants or the public prosecutor, may be held responsible for any damage occasioned by him. CELEBRATION.--Marriage must be celebrated publicly in the communal house and before the registrar of the commune where one of the parties has his or her domicile. Two witnesses are required. RECORD OF MARRIAGE.--The registrar must inscribe a record of the marriage in the civil register giving all the necessary details and must deliver an authenticated abstract of the record to the parties, who without this cannot legally claim to be married or to enjoy any of the legal consequences of marriage. ILLEGITIMATE CHILDREN.--Such children are legitimatized by the subsequent marriage of their parents, although in order to acquire the legal rights of legitimate children they must be formally recognized by their parents. These legal rights are acquired at the time of marriage only if the illegitimate children are legally recognized by their parents in the marriage record or have been legally recognized at some time prior to the marriage; otherwise they date only from the day when such recognition is given subsequent to the marriage. Children of adulterous connections and of persons between whom exists the impediment of relationship by blood or marriage in the direct line, or of relationship by blood in the collateral line up to the second degree, cannot be legitimatized.
