France passes on nationality by blood, but places limits on lineages that have long been outside the country. We assess French possession of status and the real feasibility of your case.
French citizenship follows jus sanguinis: anyone born to a French father or mother is French (Article 18 of the Civil Code). Transmission works clearly when the line has retained French nationality across generations.
There is, however, an important limit: Article 30-3 of the Civil Code (desuetude). When neither the applicant nor the French ancestor has had French possession of status (possession d’état) and the family has lived abroad for more than 50 years, the right to prove nationality by descent may be barred. That is why a feasibility assessment is essential before starting the process.
Every lineage is unique. The profiles below cover the main scenarios — an eligibility assessment confirms your specific case.
Child of a French father or mother, through direct jus sanguinis transmission.
Grandchild whose line has retained French possession of status (documents, registrations, exercise of rights).
Descendants who can prove a continuous link and use of French nationality within the family.
Article 30-3: recognition may not be possible when the line has lost French possession of status.
France is strict with distant descent: if the family lived abroad for more than 50 years without exercising the nationality (possession of status), the right to prove it by descent may be extinguished. Before any application, we assess possession of status and the alternative routes for your case.

It depends on French possession of status within the family line. Under Article 30-3, families abroad for more than 50 years without exercising the nationality may lose the right to prove it by descent. A feasibility assessment is indispensable.
It is evidence that the person or their ancestors behaved as, and were treated as, French nationals — identity documents, consular registrations, exercise of rights. It is the element that supports recognition in more distant lines.
The French Civil Code contains the desuetude rule (Article 30-3), which limits recognition of nationality in lineages that have not maintained an effective link over time. This makes France one of the most selective regimes in Europe.
There is no language requirement to prove nationality by descent. Language proof applies to naturalization routes by residence or marriage.
It varies with the documentation and the route. Cases with well-proven possession of status tend to be more straightforward; distant lines require a legal strategy upfront.
