French Citizenship by Descent: Complete Guide 2025
Claim French citizenship through your French parents or grandparents who maintained ties with France. More selective than other EU programs but offers prestigious French citizenship.
⚠️ Critical: The 50-Year Rule
This is the most important requirement: You or your French ancestor must have maintained "possession d'état" (ties with France) within the last 50 years. If your family lost all contact with French authorities for 50+ years, you likely don't qualify.
✅ Examples of Valid "French Ties":
- • Renewed French passport within 50 years
- • Registered with French consulate
- • Voted in French elections from abroad
- • Filed French tax returns
- • Applied for French social benefits
- • Contacted French authorities for any reason
❌ What Doesn't Count:
- • Simply being born in France
- • Living in France decades ago
- • Having French documents that expired 50+ years ago
- • Family stories without official proof
- • DNA tests or genealogy research alone
What is French Citizenship by Descent?
French citizenship by descent, based on the principle of "jus sanguinis" (right of blood), allows individuals with French parents to claim French citizenship. Unlike Portugal or Italy, France has stricter requirements and generally limits eligibility to direct parent lineage, though grandparent cases are possible if specific conditions are met.

Frequently Asked Questions
What exactly is the 50-year rule for French citizenship?
The '50-year rule' requires that you or your French ancestor maintained 'possession d'état' (ties with France) within the last 50 years. This means official contact with French authorities like passport renewals, consular registrations, voting, or any official French government interaction.
Can I get French citizenship through my French grandparent?
Possibly, but your parent (the child of the French grandparent) must first obtain French citizenship before you can apply. This makes the grandparent route much more complex than direct parent cases.
Do I need to speak French to get French citizenship by descent?
No, there is no French language requirement for citizenship by descent. Language tests are only required for naturalization, not for those claiming citizenship through French ancestry.
How much does French citizenship by descent cost?
Total costs range from €400-1,200, including the €55 CNF application fee, document collection (€300-400), translations (€200-600), and potential legal assistance. Much of the cost comes from gathering and translating documents.
How does French citizenship compare to Italian or Portuguese?
France is much more restrictive - requiring direct parent lineage and 50-year ties, while Italy has a 2 generation limit and Portugal allows 3 generations. However, French citizenship provides the same EU benefits with arguably more global prestige.
What documents do I need to prove my French ancestry?
You need your birth certificate, your French parent's birth certificate and citizenship documents, marriage certificates linking generations, and crucial proof that French ties were maintained within 50 years (passport renewals, consular contact, etc.).
