What Is EU Citizenship by Descent?
EU citizenship by descent is a legal mechanism that allows individuals with European ancestors to claim or restore their ancestral nationality — and by extension, become full citizens of a European Union member state. Unlike naturalization, this process does not require you to live in the country; it is based entirely on documented lineage.
Dozens of countries within the EU recognise the right of descendants to reclaim citizenship that was lost due to emigration, political persecution, or historical borders being redrawn. The most active programmes in 2025 are offered by Italy, Portugal, Hungary, Romania, Bulgaria, Poland, Lithuania, and Latvia.
Each EU country has its own citizenship laws. Some permit citizenship through unlimited generations (Italy, Romania); others limit claims to one or two generations. Always consult a legal expert before investing time in document collection.
Who Is Eligible?
Eligibility depends on three core factors: the country you are targeting, the generation through which you trace descent, and whether your ancestor lost or retained their original citizenship at any point.
Generational requirements by country
Italy is among the most permissive — there is theoretically no generational limit, as long as citizenship was passed unbroken through Italian-citizen ancestors who had not naturalised elsewhere before the birth of the next generation. Portugal's programme allows third-generation Sephardic Jewish descendants. Hungary enables ethnic Hungarians in border regions to apply.
| Country | Max generations | Processing time | Key requirement |
|---|---|---|---|
| Italy | Unlimited | 18–36 months | Unbroken chain, no prior naturalisation |
| Portugal | 3rd gen (Sephardic) | 6–12 months | Cultural connection proof |
| Romania | Unlimited | 12–24 months | Romanian-territory ancestor |
| 🇭🇺 Hungary | Unlimited | 6–18 months | Hungarian language test |
| Bulgaria | 3rd gen | 12–24 months | Bulgarian origin proof |
| 🇵🇱 Poland | Unlimited | 18–36 months | Confirmation of Polish citizenship |

Documents You Will Need
Document requirements are the most demanding part of any citizenship by descent claim. Courts and consulates require originals or certified copies of every vital record in the chain, translated into the relevant language by a sworn translator.
Core document checklist
- Ancestor's birth certificate — the original document from the country of origin, ideally with an apostille.
- Marriage certificate(s) — for every marriage in the chain, to link surnames across generations.
- Death certificate of the ancestor (where applicable).
- Naturalisation records — proof that your ancestor did not naturalise in another country before the birth of the relevant child.
- Your own birth certificate and those of all intermediate ancestors.
- Passports / identity documents for yourself and, if required, for immediate family members.
Documents older than 100 years are often in poor condition, held in local parish archives, or partially destroyed. A professional archive search significantly increases your success rate and is almost always required for Italian cases.
"The difference between a successful claim and a rejection almost always comes down to documentation quality — not ancestry itself. We have seen clear-cut cases fail because a single birth certificate used an anglicised name."— Anna Kovács, Senior Legal Consultant, getLegalStatus
The Application Process Step by Step
Once documents are collected, the process varies by country — some require filing at the consulate in your country of residence, others mandate an in-country filing. Below is the general workflow that applies to most EU countries.
Step 1 — Eligibility assessment
Before collecting any documents, confirm your legal eligibility with a specialised lawyer. This saves months of work if a disqualifying event (like an ancestor's naturalisation before a key birth) is discovered early.
Step 2 — Document collection
Begin with the oldest ancestor and work forward. Allow 6–18 months for international archive requests. Engage a certified genealogist for research in the country of origin.
Step 3 — Translation and apostille
All foreign documents must be translated by a certified sworn translator and bear an apostille under the Hague Convention. Verify the specific requirements with the receiving consulate before proceeding.
Step 4 — Filing at consulate or municipality
Depending on the country, you either file at the local consulate in your country of residence (Italy, Romania) or at a specific municipality in the target country (Portugal). File a complete dossier — incomplete submissions are returned and queue positions are lost.
Step 5 — Interview and language test (if required)
Hungary and Lithuania require a language proficiency demonstration. Bulgaria may request a cultural knowledge interview. Portugal requires evidence of connection to Portuguese culture for Sephardic applicants.
Step 6 — Decision and oath
Processing times range from 6 months (Portugal fast-track) to 36+ months (Italian consulates in certain jurisdictions). Upon approval, you take a formal oath and receive your new EU passport within weeks.
Costs and Realistic Timelines
Total costs vary widely depending on which country you target, how complex your genealogy is, and whether you engage professional help. The table below reflects typical ranges for clients working with a full-service legal provider.
| Cost item | DIY | With legal support | Notes |
|---|---|---|---|
| Archive research | €200–800 | Included | Can take 6–18 months |
| Translations | €500–2,000 | Included | Per document, sworn translator |
| Apostilles | €100–400 | Included | Varies by issuing country |
| Legal/consulting fees | — | €1,500–4,500 | One-time project fee |
| Government fees | €80–300 | €80–300 | Non-refundable, paid to consulate |
| Total (estimate) | €900–3,500 | €3,000–7,500 | Depends on complexity |
Most Common Mistakes and How to Avoid Them
1. Assuming eligibility without verification
Family oral history is not a legal document. Many applicants spend years collecting records only to discover an ancestor naturalised in the US before a key child was born, severing the Italian citizenship chain. Always start with a legal assessment.
2. Using unofficial translations
Translations from online services or bilingual friends are never accepted. Every translated document must bear the translator's stamp, certification number, and in some jurisdictions, a notarial seal.
3. Filing an incomplete dossier
At Italian consulates in particular, missing even a single document means the entire package is returned and you lose your appointment slot — which may have taken 2+ years to obtain.
Pro tip: Before filing, have your full dossier reviewed by a lawyer experienced with the specific consulate you are using. Different consulates in the same country apply rules with different levels of strictness.
Conclusion
EU citizenship by descent is one of the most life-changing legal processes available to people with European heritage. It grants you the right to live, work, and travel freely across 27 EU countries — a privilege that extends to your children and future generations.
The process is demanding but entirely achievable with proper preparation, professional guidance, and patience. The key is starting with a rigorous eligibility check, collecting clean documentation, and engaging specialists who know the specific requirements of your target country.

Finally a comprehensive guide that actually explains the naturalisation break issue clearly. I spent 3 months researching this before finding your site — the checklist alone saved me from a likely rejection. Our Italian case was approved after 26 months.
The table comparing countries is incredibly useful. I didn't realise Bulgaria's programme has a 3-generation limit — I thought it was unlimited like Romania. Really glad I read this before starting the document collection phase.
Good article overall. Would love to see more detail on the Hungarian language test requirements — what level is actually expected and whether a B1 certificate is enough or if they also do an oral interview at the consulate.
