Ius Sanguinis Citizenship

Ius sanguinis is the principle by which citizenship is passed down through ancestry. If your Italian ancestor did not renounce citizenship before the birth of the direct descendant, you may apply for recognition of Italian citizenship by descent.

We assist clients worldwide in reconstructing their genealogical line and managing the process, whether administrative or judicial.

Key Requirements

To obtain citizenship by descent, it is necessary to demonstrate:

• An unbroken line of descent from an Italian citizen (parent, grandparent, great-grandparent, etc.)
• No renunciation of Italian citizenship by the ancestor before the birth of the next descendant
• Complete documentary evidence of the entire genealogical line.

Generational Limits and Law 74/2025

Law 74/2025 introduced limitations on automatic transmission of citizenship by descent. In excluded or complex cases, targeted legal actions and strategies may be considered depending on eligibility and documentation.

Required Documents

To submit an application for Italian citizenship by ius sanguinis, the following are required:

• Birth, marriage, and death certificates for all individuals in the lineage
• Naturalization records or proof of non-naturalization of the Italian ancestor
• Certified translations and legalizations in accordance with Italian law

Exclusion Cases

The right may be lost if:

• The Italian ancestor naturalized in another country before the birth of the descendant
• A person in the lineage formally renounced Italian citizenship
