Summary

Marriage to a French citizen does not make a person French automatically. It creates a possible route to acquire nationality by declaration after the statutory waiting period, provided the French spouse has remained French and the couple's shared married life continues.

The normal waiting period is four years from the marriage. It becomes five years if, since the marriage, the applicant cannot show at least three years of continuous and lawful residence in France, or—while the couple lived abroad—the French spouse was not registered in the register of French citizens living outside France for the required period.

Since 1 January 2026, the applicant must normally prove French at B2 level in speaking and writing. The separate 2026 nationality civic exam applies to naturalization and reintegration by decree, not to a marriage declaration. An interview is still part of the marriage procedure and is used to assess the couple's shared life and the applicant's assimilation.

Only marriage supports this particular nationality declaration. A PACS, civil union, domestic partnership, engagement, or long-term unmarried relationship is not enough.

Eligibility

The applicant generally must show all of the following:

Living at different addresses does not always prove a marriage has ended—for example, work or health may explain it—but it increases the need for clear evidence. Authorities can look at joint housing, taxes, finances, insurance, children, travel, correspondence, and each spouse's explanation.

The applicant can live in France or abroad. The filing authority and documents differ by residence. A foreign marriage must be transcribed before the declaration can be registered.

What This Route Allows

If the declaration is registered, the applicant acquires French nationality on the legally effective date. The person can then obtain updated French civil-status records and apply for a national identity card and passport.

Unmarried minor children may sometimes receive nationality through the collective effect of the parent's acquisition if they live with the applicant and are named in the declaration. Check custody and residence evidence before filing.

What This Route Is Not

This is not a spouse visa or residence card. A non-French spouse who wants to move to France must separately meet the entry and residence rules. Having a French-spouse residence permit does not itself complete the nationality process.

It is not a route for PACS or unmarried partners, and marriage alone does not guarantee registration. France can refuse or oppose the acquisition where the legal conditions are not met, the shared life is not genuine or continuous, records are false, or serious public-order issues exist.

The four-year mark is not always the correct filing date. Couples with substantial time abroad must check the three-year residence and consular-registration rules carefully before choosing between four and five years.

Next Steps

  1. Confirm the spouse was French on the wedding date and gather accepted evidence that the spouse remains French.
  2. Calculate the marriage period and determine whether the four- or five-year rule applies using the couple's exact residence and consular-registration history.
  3. If married abroad, obtain transcription into the French civil-status register before filing.
  4. Build evidence of continuous shared emotional and material life from the wedding to the present.
  5. Obtain current B2 language evidence or verify an official exemption or medical accommodation.
  6. Gather full civil-status records, residence records, criminal-record certificates, and translations/legalization required by the current checklist.
  7. File with the competent nationality platform in France or the French consulate when resident abroad, and prepare both spouses for the interview.
  8. Keep the marriage and shared-life evidence current while the declaration is processed; the conditions continue to matter after filing.
