The 1948 rule.
The maternal line.
If your Italian citizenship passes through a woman who had children before January 1, 1948, the consulate cannot process your application. You need a court case in Italy.

Why this rule exists
Before 1948, Italian citizenship law (Law 555/1912, Art. 1) stated that only fathers could transmit citizenship. Mothers could only transmit in limited cases: father unknown, stateless, or child born out of wedlock.
On January 1, 1948, the Italian Constitution came into force. Article 3 established equality before the law without regard to sex. But it took decades for this principle to be applied to citizenship.
Law 555: only fathers transmit citizenship
Italian Constitution: gender equality (Art. 3)
Const. Court 87/1975: unconstitutional to lose citizenship through marriage
Const. Court 30/1983: unconstitutional to limit transmission to fathers. But only from 1948 forward
Law 91: full equality (“father or mother”)
Cass. Sez. Un. 4466/2009: extends to pre-1948 births — but only through courts
Does this apply to you?
Two questions:
1. Does the chain go through a woman?
Trace the descent from your Italian ancestor to you. If at any point citizenship passes from mother to child, and that child was born before January 1, 1948, you have a 1948 case.
2. If the chain only goes through men?
No gender issue. You can use the consular route (1st-2nd generation) or the judicial route for the generation limit (3rd+ generation). The 1948 rule doesn’t apply.
The three most common scenarios
Italian grandmother, child born before 1948
Woman born in Italy, married a foreigner. Her child was born before January 1, 1948. Under the law at the time, the child didn’t acquire citizenship from the mother. The court case recognises the child’s citizenship from birth, allowing the chain to continue to you.
Italian woman lost citizenship by marrying a foreigner
Art. 10 of Law 555/1912: Italian women automatically lost citizenship when marrying a foreigner. The Constitutional Court (87/1975) declared this loss unconstitutional. But the consulate won’t process it for pre-1948 events — you need the court.
Combined scenario: naturalisation + gender
Your Italian ancestor (male) emigrated. He had a daughter (Italian citizen). The daughter had children before 1948 with a foreign husband. Those children didn’t acquire citizenship through the mother. The 1948 case resolves this. But you also need to check that the original ancestor’s naturalisation didn’t break the chain before reaching the daughter.
How the court process works
You don’t need to go to Italy. The attorney handles everything remotely through a power of attorney.
Hire an Italian attorney
Must be registered with the bar. You cannot self-represent. Budget: €4,000-10,000.
Gather the documents
Birth, marriage, death, naturalisation certificates for the full chain. All apostilled and translated into Italian.
Power of attorney
Signed, apostilled, translated document authorising the attorney. Cost: €50-150.
File at the tribunal
Most cases go to the Tribunale di Roma. Since June 2022, you can also file at your ancestor’s local tribunal.
Hearing
1-2 hearings. The judge reviews documentation and the legal argument. You don’t need to attend.
Ruling
If successful, the court declares you’ve been Italian from birth. Success rate: ~95% for properly documented cases.
Registration
The ruling is transcribed into Italian civil registers. Timeline: 1-3 months.

What’s still unclear
Does the generation limit apply to 1948 cases?
Law 74/2025 introduced a 2-generation limit for the consular route. 1948 cases are constitutional rights claims (gender equality). Many attorneys argue that ordinary legislation cannot retroactively limit constitutional rights. The Constitutional Court upheld the law on 12 March 2026, but the full written reasoning hasn’t been published yet. No court has tested this interaction.
The minor issue (April 14, 2026 hearing)
Separate from the gender question: if a minor child was naturalised with their parent by operation of foreign law, Art. 12 of Law 555/1912 may have caused automatic loss of Italian citizenship. The Cassazione Sezioni Unite will rule on April 14, 2026. This can affect 1948 cases where the chain includes a minor who lost citizenship with their father.
Practical advice: anyone with a pre-1948 case should have filed by March 27, 2025 (clause (b) of Art. 3-bis). Those who didn’t can try the constitutional rights argument, but it’s untested territory.
Frequently asked questions
Did the 1948 rule change with Law 74/2025?
The law itself doesn’t directly mention 1948 cases. But the new generation limit (Art. 3-bis) could apply to judicial cases too. It hasn’t been tested in court yet. If you didn’t file before March 27, 2025, the situation is uncertain.
Do I need to travel to Italy for the court case?
No. The Italian attorney acts on your behalf through a power of attorney (procura speciale). You don’t need to attend hearings. The entire process can be managed remotely.
How much does it cost in total?
Realistic budget: €6,000-13,000 all-in (attorney €4,000-10,000 + court filing fee €600 + documents, apostilles, translations). US-facing firms may charge €8,000-15,000 in attorney fees alone.
How long does it take?
From filing to ruling: 12-24 months typically. Up to 36 with backlogs. Then 1-3 months for registration. Total: 14-27 months.
What’s the success rate?
About 95% for properly documented cases. Failures are almost always due to incomplete documentation, not the legal merits. The gender discrimination is an incontestable historical fact.
Can I include my whole family in one case?
Yes. Multiple family members can be petitioners in the same case, sharing the attorney costs. Typical discount is 30-50% per additional person.
