How Italian citizenship by descent works
The eligibility rules for Italian citizenship by descent, in plain English — who may qualify, what disqualifies, and the legal regimes over time, each cited to its primary statute.
Who may qualify
A qualifying path — via the consular route
Date keying
- In force during the window 2025-07-01 up to (but not including) 2028-01-01 — keyed on the assessment date, not on anyone's birth.
Requirements
ALL of the following
the applicant has a recorded citizenship held such that country = italian, lost at = {"on_or_before":"1992-08-16"}. If this fact is absent, the rule treats it as not applying (rather than asking for more information).
- country:
- italian
- lost at:
- {"on_or_before":"1992-08-16"}
the applicant has a recorded reacquisition declaration. If this fact is absent, the rule treats it as not applying (rather than asking for more information).
ANY of the following
the applicant has a recorded birth such that country = italy. If this fact is absent, the rule treats it as not applying (rather than asking for more information).
- country:
- italy
the applicant has a qualifying italy residence (min two years).
- min two years:
- true
Primary sources
- § Codice Civile / Law 91/1992 art. 13 (reacquisition), reopened by L. 74 of 23 May 2025 — former citizens who lost Italian citizenship on/before 1992-08-16 may declare reacquisition 1 Jul 2025 – 31 Dec 2027 if born in Italy or resident ≥2 years
- § Law 91/1992 art. 15 (prospective effect) + art. 14 (minor children do not acquire automatically)
A qualifying path — via the court route
Date keying
- In force from 2025-03-28 onward — keyed on the assessment date, not on anyone's birth.
Requirements
ALL of the following
Must NOT be true
the applicant's link to the qualifying ancestor is by adoption (rather than by birth).
- tie is adoptive:
- yes
the applicant has a qualifying descent path (includes pre 1948 maternal link).
- includes pre 1948 maternal link:
- true
the qualifying ancestor must have held italian citizenship at the moment the applicant was born, passing it down the line by descent. Where the claim runs through more than one generation, a later loss of that citizenship is measured against the birth of that ancestor's own child on the line — the point at which it would have passed down — rather than against the applicant's birth.
- required citizenship:
- italian
Primary sources
- § Cass. SS.UU. n. 4466/2009
- § Costituzione della Repubblica Italiana, art. 3 (1948 constitutional challenge)
- § Corte cost. ord. n. 147/2026 (dep. 23 luglio 2026): art. 3-bis l. 91/1992 rinviato in via pregiudiziale alla CGUE (artt. 9 TUE / 20 TFUE); giudizio costituzionale SOSPESO — the 2025 reform's retroactive preclusion is no longer settled domestically
A qualifying path — via the consular route
Date keying
- In force from 2025-03-28 onward — keyed on the assessment date, not on anyone's birth.
Requirements
ALL of the following
Must NOT be true
the applicant's link to the qualifying ancestor is by adoption (rather than by birth).
- tie is adoptive:
- yes
ANY of the following
the applicant has a recorded birth such that country = italy. If this fact is absent, the rule treats it as not applying (rather than asking for more information).
- country:
- italy
the applicant has a qualifying other citizenship (none). If this fact is absent, the rule treats it as not applying (rather than asking for more information).
- none:
- true
the qualifying ancestor must have held italian citizenship at the moment the applicant was born, passing it down the line by descent. Where the claim runs through more than one generation, a later loss of that citizenship is measured against the birth of that ancestor's own child on the line — the point at which it would have passed down — rather than against the applicant's birth.
- required citizenship:
- italian
the qualifying ancestor must not have naturalized as a citizen of another country before the applicant was born.
Every intermediate ancestor between the applicant and the qualifying ancestor must have still held citizenship when they passed it to the next person down the line (the chain must be unbroken), where a break can be caused by: naturalization.
- chain-breaking events:
- naturalization
Caution flag (never a disqualifier): raises an unsettled-law warning when an ancestor on the line naturalized while their child was still a minor — the contested Italian “minor issue”. It can only downgrade a result to “needs more info” and advises seeking counsel; it never marks anyone ineligible, using 21 as the age of majority.
- age of majority:
- 21
Primary sources
- § Law 91 of 5 February 1992, Art. 1 — unrestricted jus sanguinis governs persons OUTSIDE Art. 3-bis scope (born in Italy, or holding no other citizenship)

- § Art. 3-bis letter (c) — co-applicable basis for grandparent-depth cases where the qualifying ancestor held Italian citizenship exclusively

the applicant must be the grandparent of the qualifying ancestor.

the qualifying ancestor must have held italian citizenship at the moment the applicant was born, passing it down the line by descent. Where the claim runs through more than one generation, a later loss of that citizenship is measured against the birth of that ancestor's own child on the line — the point at which it would have passed down — rather than against the applicant's birth, and must have held it exclusively (no second citizenship at that time).
- required citizenship:
- italian
- exclusive only:
- yes
the qualifying ancestor must not have naturalized as a citizen of another country before the applicant was born.
