Italian citizenship through the maternal line before 1948
Under the law of 1912 an Italian woman who married a foreigner took his citizenship and lost her own. The Constitutional Court, in judgment 87/1975, held that rule contrary to the equality of the sexes, and the effect of the judgment runs from 1 January 1948, the day the Constitution came into force. A woman who married a foreigner after that date, and acquired his citizenship by the marriage, never ceased to be Italian. The Ministry of Foreign Affairs provides for a declaration by which she, or her descendants, have that fact recorded. For the Italian women who married British men after the war this page is the starting point.
The declaration of uninterrupted possession
A woman who, after 1 January 1948, acquired a foreign citizenship automatically through the marriage, or through the naturalisation abroad of a husband born Italian, kept the Italian citizenship without interruption. She, or her descendants, make a declaration before the consular officer stating the wish to retain the citizenship and asking for the marginal annotations on the civil status records. It is not an application for citizenship and not a reacquisition. It confirms a status which was never lost, and once the record is annotated the descendants are examined as the descendants of an Italian citizen.
The documents are those of the woman: her Italian birth certificate, the marriage certificate, the foreign document which shows the acquisition of the husband’s citizenship and its date, her own identity document or death certificate, and the certificates which link the descendants to her. The consulate verifies the position with the comune and annotates the records.
Automatic or requested: the point which decides British cases
The declaration covers an acquisition which happened by operation of the foreign law. British law changed on 1 January 1949. Until 31 December 1948, under the British Nationality and Status of Aliens Act 1914, a foreign woman who married a British subject became a British subject by the marriage, automatically. From 1 January 1949, under the British Nationality Act 1948, the wife of a citizen was entitled to be registered as a citizen of the United Kingdom and Colonies on her own application, and nothing happened without it. From 1 January 1983 the British Nationality Act 1981 ended that entitlement, apart from transitional provisions, and a foreign wife naturalises like anyone else.
The consequence for an Italian woman is this. If she married a British man in 1948 she became British automatically and remained Italian, and the declaration of uninterrupted possession applies. If she married in 1955 and never applied for registration, she remained Italian and never became British, and no declaration is needed beyond the registration of the marriage. If she married in 1955 and applied for registration in 1960, the consulate examines whether the acquisition was a voluntary act under article 8 of the law of 1912, with the loss of Italian citizenship on that date, and the route then becomes the reacquisition described in its own page, open until 31 December 2027 for a woman born in Italy. Whether a registration which the law offered only to wives is treated as voluntary has been argued both ways, and we say in the written assessment how the consulate of the district applies it.
Two sisters born in Scapoli in 1925 and 1929 came to Scotland. The elder married a Scottish miner in July 1947 and became a British subject by the marriage. She lost Italian citizenship under the law of 1912, because the marriage precedes 1 January 1948, and her children born in the 1950s cannot be recognised by the consulate. Their claim, through the maternal line before 1948, can only be decided by a court, and we do not handle court proceedings. The younger sister married in October 1948. She became British by the marriage and remained Italian. Her descendants record the uninterrupted possession at the consulate and are then examined by descent, subject to article 3-bis.
Marriages before 1948 and the maternal line
For a marriage before 1 January 1948 the loss stands in the administrative practice. The woman can reacquire citizenship by declaration under article 219 of Law 151/1975. Her children born before 1948 are not recognised by the consulates, because at their birth the mother was not Italian for the law then in force and the mother did not transmit citizenship in any case under the law of 1912. The Court of Cassation, in judgment 4466/2009 of the United Sections, held that the descendants of such a woman can obtain a judicial declaration of their citizenship, and these claims, known as 1948 cases, have been decided by the Italian courts for fifteen years. Since 28 March 2025 a claim filed after that date is subject to the conditions of article 3-bis, and the Constitutional Court in judgment 63/2026 found no objection to that. A claim filed by 27 March 2025 is decided under the earlier rules.
We prepare the documents, the research and the translations for families who instruct a lawyer in Italy for such a claim, and we say in the written assessment whether the line falls within the conditions which a court would now apply.
Children born after 1948 to an Italian mother
A child born after 1 January 1948 to an Italian mother is Italian by descent through her, whatever the father’s citizenship, by effect of judgment 30/1983 of the Constitutional Court and of the consular practice which followed. The line is examined like a paternal line, generation by generation, with the mother’s uninterrupted possession recorded first where she married a foreigner.
If your mother or grandmother was Italian and married a British man, send us the date of the marriage, the place of her birth and whatever British document she held. Those three facts tell us which of the situations on this page is yours.
