GUIDE · PRATICA
The complete journey from 'my grandparent was Italian' to holding your passport. UK-specific, and written against Art. 3-bis rather than the test it replaced.

Overview
The grandparent is as far back as a new jure sanguinis application reaches. That much is well known. What is less well known is that reaching the grandparent is not the same as qualifying through them: Art. 3-bis of Law 91/1992, in force since 24 May 2025, keeps the grandparent route open only where that grandparent held exclusively Italian citizenship, or where a parent lived in Italy for two continuous years after acquiring citizenship and before you were born. The Art. 3-bis guide sets out all five conditions.
The process has five phases. Each depends on the previous one. Rushing ahead or doing steps out of order adds months. The realistic total timeline is 1-3 years from first document request to passport in hand.
| Phase | Duration | What happens |
|---|---|---|
| 1. Eligibility check | 1-2 weeks | Settle which condition of Art. 3-bis the claim runs on, before buying a certificate |
| 2. Document gathering | 2-6 months | Obtain, apostille, translate every certificate in the chain |
| 3. Consulate appointment | 1-12 months | Secure a Prenotami slot and attend with full document set |
| 4. Comune processing | 6-24 months | Italian municipality verifies records and updates civil registry |
| 5. Recognition + passport | 1-3 months | Comune transcribes, AIRE entry, then the separate passport application |
Phase 1
Before ordering a single certificate, settle these five questions. Getting any of them wrong means paying for documents that cannot be used, and the certificates are not the expensive part — the year is.
1. Was anything lodged by 27 March 2025?
An application filed with a consulate or comune, a confirmed appointment, or a court filing, all by 23:59 Rome time on that date. If so, conditions (a), (a-bis) or (b) apply and the file is judged under the pre-reform law. Nothing below changes that, and it is worth confirming in writing before assuming either way.
2. Did the grandparent hold only Italian citizenship?
This is condition (c), and it is the question that decides most British files. It is not the old question of whether they naturalised before your parent was born. It asks what they held: exclusively Italian citizenship, now or at the time of their death. A grandparent who also became British does not satisfy it, whenever that happened. See the Art. 3-bis guide for the full decision tree.
3. If not, did a parent live in Italy for two years?
Condition (d): a parent or adoptive parent resident in Italy for at least two continuous years after acquiring Italian citizenship and before your birth or adoption. It carries no exclusivity requirement and no generation count, and it is routinely missed because it looks like a residence rule rather than a descent one. Italian residence records are the evidence.
4. Can the exclusivity be documented?
Circolare 26185 of 28 May 2025 requires the absence of any other nationality to be proved on paper. A self-declaration is not accepted. What satisfies it differs by consulate, and the proof has to cover the right span of years rather than today. This is the step where files that look complete are turned away.
5. No female ancestor with a child born before 1948
If the chain passes through a woman who had a child before 1 January 1948, the administrative route is closed and the claim is court work, resting on Cassazione, Sezioni Unite 4466/2009. Anyone who did not file by 27 March 2025 is in untested ground: Sentenza 63/2026 upheld Art. 3-bis without addressing those cases. That is a conversation for an Italian avvocato, not for us.
Phase 2
Phase 2 is not collecting documents: it is constructing a legal argument. The right to citizenship by descent already exists under Law 91/1992; the file is the medium through which it is recognised. Each document either supports the chain's continuity or admits something that breaks it. Documents that simply “exist” without contributing to that argument do not strengthen the file.
A two-generation file passes through several issuing authorities across two jurisdictions, the Hague Convention 1961 apostille system, sworn translation, and notarial certification. Each layer authenticates a different actor: not the document's content. Misplacing a layer is the most common technical failure; misreading the chain's legal continuity is the most common substantive one. Both end the same way: the appointment is not productive.
The evidentiary file guide discusses how the layers fit together and where files most often fail.
Phase 3
Consular jurisdiction is determined by the applicant's registered UK residence under DPR 200/1967: not by the ancestor's origin or the applicant's place of birth. London, Manchester and Edinburgh each handle their share, and each has its own reading of marginal cases. The consulates guide covers the differences.
For most UK applicants, securing the appointment is the longest-running stage of the entire route. This is where most people stall: not because the file is wrong, but because access to the consular calendar is the binding constraint.
At the appointment, a consular officer reviews the file as a whole. There is no partial submission: a single missing or incorrect element ends the day, and the next slot is months away. The cost of a failed appointment is the slot itself, not the documents.
Phase 4
After submission, the consulate forwards your file to the comune in Italy where your ancestor's birth was registered. The comune cross-references your documents against their civil registry.
This is entirely out of your control. Processing times range from 3 months (small comuni with few pending requests) to 24 months (large cities with backlogs). There is no way to expedite it. The consulate will contact you when the comune confirms.
Phase 5
There is no oath on this route. It is worth saying plainly, because it is one of the most commonly repeated errors about jure sanguinis and because people arrive expecting a ceremony that will not happen. Recognition by descent is declaratory: it records that you have been an Italian citizen since birth. There is nothing to swear and nothing to grant. The oath belongs to the other routes, acquisition by marriage and by residence, where citizenship really is conferred and a decree really does have to be finalised.
What happens instead is quieter. The comune transcribes the records into its civil registers, the recognition is recorded, and you are entered on AIRE, the register of Italians resident abroad. The €600 contributo was already paid when the application was made, not at the end.
Once the AIRE entry is confirmed the passport channel opens. The passport is a separate administrative act with its own evidentiary standard, which is why a recognised citizen can still be turned away at that stage: the file that proved the descent is not the file that gets a passport issued.
What this route actually costs
Aggregate fees for a standard two-generation file are modest by the standards of any comparable legal process. They are also public, set by the issuing authorities, and easy to total.
The real cost of this route is not measured in fees. It is measured in time-to-recognition: the months between the first document request and the comune's inscription. That figure is sensitive to a small number of binding constraints, the consular slot, the comune's queue, the legalisation cycle, and how many times any of the three has to be repeated. A file that lands clean the first time spends months in this route. A file that does not, spends years.
The economically important question is therefore not “what does this cost in fees?” but “what is the expected number of consular cycles this file will need?”
FAQ
Realistically: 1-3 years. The fastest cases (parent born in Italy, all documents ready, short Prenotami wait) can complete in 8-12 months. The slowest (complex family history, large comune backlog, scarce appointment slots) take 3+ years.
For most UK chains, complexity concentrates at four points: the 1992 reform of citizenship loss (Law 91/1992 vs the older Law 555/1912 regime), the 1948 transmission rule for the maternal line, the question of minor naturalisation under Law 555/1912 Art. 7 vs Art. 12 (currently before the Corte di Cassazione, Sezioni Unite), and the reconciliation of names and dates across UK and Italian civil registries.
None of these are visible from the document itself. They are inferences drawn from the chain of records. A file that is documentarily complete can still fail on any of these points : and conversely, a file that looks thin can be argued through successfully when the legal reading is correct.
No. The claim is based on the unbroken chain of citizenship, not on living relatives. You need your grandparent's birth certificate, marriage certificate, and death certificate (if deceased). The documents prove the chain; the individuals do not need to participate.
Italian comuni have merged, split, and renamed over the past century. The ANPR portal maps old comuni to their current equivalents. If the original comune was absorbed into a larger one, the successor holds the records. Start with ANPR; if that fails, contact the Archivio di Stato for the relevant province.
Not necessarily. In many cases, you can apply directly. Your application demonstrates that your parent inherited citizenship from your grandparent, and you inherited it from your parent. The consulate processes the entire chain at once. However, some consulates prefer the parent to apply first or concurrently. Check with your specific consulate.
SOURCES AND VERIFICATION
Scope. This page is about the grandparent route on the administrative track: what Art. 3-bis requires, and the five phases from first certificate to passport. It is not about court proceedings, and it is not a document checklist. Where a file needs the pre-1948 maternal line, or a refusal has to be challenged, that is work for an Italian avvocato and we say so rather than take it on. General information, not legal advice.
What the label means. “Read” means we hold the document and have read it. “Reported” means a secondary source describes it and we have not read the primary text: we will not use it to tell you what it says. “Not held” means the route rests on that judgment but we do not have a copy, and we say so rather than imply otherwise.
