Updated Requirements for Italian Jure Sanguinis Citizenship in 2026

The legislation and administrative practice in 2026 have consolidated the judicial route as the main path for many applicants seeking Italian citizenship jure sanguinis, due to legal changes that heavily restricted administrative consular and municipal avenues. This text explains who can apply, which documents to prepare, how the judicial process works in Italy, and tips for assembling a complete dossier.

Current overview: administrative restrictions and emphasis on the judicial path in Italy

Since the publication of the so-called Decreto Tajani (DL 36/2025, converted into Law 74/2025), regulations on recognizing citizenship by descent have changed substantially. The decree restricted administrative consular recognition, limiting it to children and grandchildren of Italians, and also altered administrative practice in the comuni: after Decreto 36/2025, administrative recognition at the comune is no longer feasible in most cases for foreign applicants pursuing jure sanguinis (i.e., the municipal route is generally no longer available for these petitions).

The Decreto Tajani (DL 36/2025 / Law 74/2025) is a restrictive rule that narrows the scope of administrative recognition and has the practical effect of limiting rights in certain circumstances. As a practical consequence, the judicial route remains the accessible channel for many applicants (including great-grandchildren and later generations), even though it is subject to the new rules set by the decree and to the interpretation of case law.

The Sezioni Unite of the Corte di Cassazione play a central role in standardizing judicial decisions on citizenship, and their interpretations have binding force for judges. Note that the debate over the retroactivity of Decreto Tajani touches on the substantive right: the decree declares effects that affect the existence of the right from birth in certain cases, and this issue has been the subject of judicial controversy.

Who can apply: basic eligibility and bloodline

The basic eligibility to pursue jure sanguinis citizenship remains tied to bloodline: you must prove that Italian citizenship was transmitted by an Italian ancestor without grounds for loss. Key notes:

• The consular route is now restricted to children and grandchildren of Italians, according to the text of Decreto Tajani (DL 36/2025 / Law 74/2025) and official communications; great-grandchildren and later generations, as a rule, do not obtain administrative consular recognition.
• Great-grandchildren and later generations will often need to file a judicial action in Italy to obtain recognition.
• The retroactivity of Decreto Tajani affects substantive rights in certain aspects: the decree declares effects that may eliminate, in certain circumstances, a right the person held since birth. This issue is being debated in higher courts and analyzed by the Sezioni Unite.

To better understand practical and legal impacts, consult official judicial decisions and announcements from the Ministry of Interior and the Corte di Cassazione.

Essential documents: birth, marriage certificates, acts and translations

A well-organized dossier is decisive. Documents commonly required in jure sanguinis processes include:

• Birth certificates (acta di nascita) of all Italian ancestors and the applicant.
• Marriage certificates and any death certificates of the ancestors.
• Proof of naturalization (or non-naturalization) of the Italian ancestor — for example, certificate of citizenship acquisition from the foreign country where they lived.
• Identification documents (passport, ID card, tax ID) and evidence of family ties (civil registry).
• Certified translations into Italian and Haifa apostille where applicable.

Additionally, police clearance or negative background certificates from the applicant’s country of residence may be requested. The exact requirement varies by tribunal and the evidentiary content presented; therefore, prepare full copies and certified translations.

Background checks and negative certificates

Italian tribunals often require certificates proving the absence of legal impediments. There is no single universal list; consult the attorney handling the case to confirm which specific certificates will be required for the competent judge.

How to prepare documentation for the Italian judicial process

• Gather complete and old certificates (originals or authenticated copies).
• Arrange certified translations into Italian and apostilles when the document was issued outside Italy.
• Organize certificates in chronological order of the lineage.
• Keep high-quality digital copies for sending to the attorney and for filing.

See our practical guides in Vida na Itália for guidance on translation and apostille.

Judicial procedure in Italy: steps, timelines, and competent bodies

The typical judicial process for recognizing jure sanguinis follows these general steps:

1. Preparation of the dossier and engagement of a specialized Italian attorney.
2. Filing the action with the competent court (Tribunale ordinario) of the location indicated by law and jurisprudence.
3. Evidence phase, which may include requests for additional documents, expert opinions, or witness testimony.
4. Judge’s sentence recognizing — or not — the citizenship.
5. Possible appeals to higher courts (Corte d’Appello and Corte di Cassazione), depending on the case.

Timelines vary greatly depending on the court and case complexity; cases can take from several months to several years depending on court workload and need for evidentiary production.

Typical costs of the process and legal assistance

There is no single official cost table; expenses usually include attorney fees, court fees, translations, and obtaining documents abroad. It is common to negotiate fees with specialized lawyers or firms that operate in Italy. For realistic estimates, consult attorneys and official sources.

Tips to avoid common delays

• Submit complete certificates properly apostilled.
• Anticipate certified translations.
• If possible, appoint lawyers with local presence at the competent court.
• Monitor deadlines and notifications promptly.

Common errors that affect approval

• Submitting incomplete certificates or those lacking apostille/certified translation.
• Failing to prove the direct transmission line of citizenship with continuous documentation.
• Ignoring the effects of older naturalizations of the ancestor (for example, historical provisions like Law 555/1912 on automatic loss for minors at certain times).
• Underestimating evidentiary requirements requested by the judge.

Impact of recent legislative and jurisprudential changes

The changes brought by Decreto Tajani (DL 36/2025 / Law 74/2025) and decisions of the Sezioni Unite of the Corte di Cassazione have increased the need for detailed legal evaluation in each case, especially regarding retroactivity and application of substantive law. In light of this, constant monitoring of official decisions and guidance from a qualified attorney is recommended.

Estimated timeline: from filing to decision

A realistic timeline should consider:

• Dossier preparation: weeks to months.
• Initial filing and hearing: months to years, depending on the court.
• First-instance decision: typically 6 months to 2 years or more.
• Appeals: can add years to the process.

Best practices for those starting now

• Create a complete inventory of Italian ancestors with birth dates and places.
• Request old certificates as soon as possible (courthouses and archives).
• Seek specialized citizenship legal guidance in Italy before filing actions.
• Maintain an organized file (physical and digital) with originals, translations, and receipts.

How to organize a complete dossier

• An index listing the documents.
• Authenticated copies of birth, marriage, and death certificates.
• Proof of naturalization (or absence thereof) of the Italian ancestor.
• Certified translations and apostilles separated by document.
• Timeline for submission and filing.

Useful resources and official sources

• Text of Decreto Tajani: DL 36/2025 / Law 74/2025 (official government publications).
• Decisions of the Corte di Cassazione (Sezioni Unite) available on the Corte di Cassazione website.
• Announcements from Italian consulates and the Ministry of the Interior for administrative guidance.
• See our pages on Cidadania Italiana and updates in Notícias da Itália.

Conclusion In 2026, Italian jure sanguinis citizenship requires rigorous documentary preparation and, for many generations, judicial action in Italy due to restrictions introduced by Decreto Tajani. Keeping abreast of judicial decisions and official announcements and organizing a complete dossier are essential steps to increase the chances of recognition.
