Guide
Documents you need
A jure sanguinis application requires civil records for every person in the chain from the Italian ancestor down to you. Each document must be apostilled and translated. Missing one means the consulate cannot accept the application — there is no partial submission. This guide covers what UK applicants need, where to get it, and in what order.
Italian certificates
Request these from the ufficio di stato civile of the relevant comune. Write in Italian, include the full name as it would appear in Italian records, date of birth in DD/MM/YYYY format, and parents' names. State the purpose as “ricostruzione della cittadinanza italiana.” Expect 2–4 months for a response. One polite follow-up after 6–8 weeks is reasonable.
| Birth certificate | Comune of birth | Estratto per riassunto dell'atto di nascita — not the certificato. The estratto includes marginal annotations showing marriages, citizenship changes, and other events. |
| Marriage certificate | Comune where married | Estratto per riassunto dell'atto di matrimonio. Only needed if married in Italy. |
| Death certificate | Comune where died | Only if the ancestor died in Italy. |
Italian certificates do not need apostilles or translations — they are already in Italian and issued by an Italian authority.
Certificate types — the most common mistake
Correct
Estratto per riassunto
Contains marginal annotations showing marriages, citizenship changes, death, and other events registered against the record. The consulate needs these annotations to verify the chain.
Request: “estratto per riassunto dell'atto di nascita”
Wrong
Certificato
A plain statement of facts without marginal annotations. No record of subsequent life events. The consulate cannot verify the citizenship chain from a certificato alone.
Do NOT request: “certificato di nascita”
UK certificates must be the full version showing both parents' names. The short extract (common for some purposes) does not contain enough information. Order full certificates from GRO for England and Wales, or NRS for Scotland.
UK certificates — for each person in the chain
| Birth certificate | GRO (England/Wales), NRS (Scotland), GRONI (N. Ireland) | Full certificate showing both parents' names. Short extracts are not accepted. GRO: gro.gov.uk, currently £12.50 standard. |
| Marriage certificate | GRO, NRS, or GRONI | Required for each marriage in the chain. |
| Death certificate | GRO, NRS, or GRONI | If the person is deceased. |
Proof of non-naturalisation
The consulate needs official proof that any ancestor claimed to hold Italian citizenship never became British. Self-declarations are explicitly rejected — the London consulate states this in writing. For UK residents, records are split at 1 October 1986. Anyone who lived in the UK before that date needs certificates from both bodies.
| Letter of No Evidence | The National Archives, Kew | Covers naturalisation records from November 1844 to October 1986. Apply online at nationalarchives.gov.uk/letter-of-no-evidence/. Fee: £38.95 (from 1 April 2026). Processing: 16 working days. |
| Form NQ confirmation | UK Visas and Immigration (Home Office) | Covers October 1986 onwards. Postal application only. Fee: £459 (non-refundable). Processing: 10 working days by card. Valid only 3 months from issue — plan timing carefully. |
Note: the “CONE” (Certificate of Non-Existence of Naturalisation) sometimes referenced in guides is a US-specific document from USCIS. It does not exist in the UK system. The UK equivalents are the two documents above.
For the applicant
| Birth certificate | GRO, NRS, or GRONI | Full certificate, not short form. |
| Marriage certificate | GRO or equivalent | If married. |
| Proof of UK residence | Council tax bill, utility bill, or bank statement | Some consulates require this. Check with yours. |
| Valid passport or ID | HM Passport Office | Photocopy usually required. |
The order of operations
This sequence matters. Getting it wrong means redoing work.

What it actually costs
Sample cost · 3-generation case with 6 UK certificates
Plus €600 government recognition fee per person. Actual costs vary by number of certificates and countries involved.
Scottish documents
NRS can “authenticate” Scottish registration documents with a stamp confirming genuineness. This is not the same as an apostille. Italian consulates require an FCDO apostille regardless of whether the NRS authentication stamp is present. Scottish documents go through the same FCDO process as English and Welsh ones.
Consulate requirements vary and change. Confirm the exact document list with the consulate covering your area before ordering — see our UK consulates guide for contact details and jurisdiction boundaries.
