Married to a French national? You can acquire nationality by declaration, without waiting for the 5 years of residence required for naturalization by decree. Here are the exact 2026 conditions and the pitfalls to avoid.
Acquiring French nationality through marriage is not a “classic” naturalization: it is a declaration. If the conditions are met, the administration can only object on specific grounds (lack of assimilation, unworthiness, threat to public order).
The marriage durations to meet
The declaration is possible after 4 years of marriage, provided that the community of life (emotional and material) has not ceased since the marriage. This period is extended to 5 years if, at the time of the declaration, you cannot prove regular and uninterrupted residence of at least 3 years in France since the marriage.
The community of life must be real and ongoing. The administration can verify it, including through an investigation.
The required French level
Since 1 January 2026, the spouse must prove a B2 level of French (up from B1 previously). This increase applies to declarations filed from that date. The level is proven by a diploma or a recognized test (TCF, TEF).
Assimilation and respect for values
As with naturalization by decree, you must demonstrate your assimilation : sufficient knowledge of the language, but also of the rights and duties of a French citizen, and adherence to the principles of the Republic. An interview may be arranged.

The declaration is filed with the competent authority with a file including in particular:
- The marriage certificate and birth certificates (sometimes translated and legalized).
- Proof of the spouse’s French nationality.
- Proof of community of life (shared home, joint accounts, etc.).
- The B2 language level certificate.
- A criminal record extract.
After registration, the administration has a period to object where applicable. In the absence of a well-founded objection, nationality is acquired.
