Citizenship Jure sanguinis / by descent

General information – legislation

Italian Citizenship is based upon the principle of “ius sanguinis” (blood right) meaning that the child born from an Italian father or mother is an Italian citizen regardless the place of birth.

Italian citizenship is now regulated by Law n. 91 of February 5, 1992 in force from August 16, 1992. Since then the subject of Italian citizenship has been regulated by the Law 555 of June 13, 1912 that has been repeatedly amended following some Constitutional Court’s resolutions, the new Family Law of 1975 and the law 123 of April 21, 1983.

Law 123/1983 abrogated the automatic acquisition of the Italian citizenship by a foreign woman who married with an Italian citizen and ruled that it was possible to acquire Italian citizenship through the maternal line. The latter is applied to those born after January 1, 1948. The innovations introduced by the present legislation are:

– Acknowledgment of the equal rights between a man and a woman;
– maintaining Italian citizenship after foreign naturalization;
– the importance of formal expression of personal will.
