When a parent regains French nationality, do their minor children automatically benefit? The answer depends entirely on when the reinstatement took place – and the dividing line is 1 January 1994, the date the 1993 nationality reform came into force.
Before 1994: No Residence Requirement
Under the Code de la nationalité française (CNF) of 1945, the collective effect of a parent’s acquisition of French nationality was governed by Article 84 CNF, which provided:
“L’enfant mineur de dix-huit ans, légitime, naturel ou ayant fait l’objet d’une adoption plénière, dont l’un des deux parents acquiert la nationalité française, devient français de plein droit.”
The rule was straightforward: a minor child (under 18), whether legitimate, illegitimate, or the subject of a full adoption, became French by operation of law the moment one of their parents acquired French nationality. No habitual residence with that parent was required.
This mechanism was expressly extended to reinstatements (réintégration) by Article 97-6 CNF:
“La réintégration par décret ou par déclaration produit effet à l’égard des enfants âgés de moins de dix-huit ans dans les conditions des articles 84 et 85 du présent titre.”
The only statutory exception was set out in Article 85 CNF, which excluded married children:
“Les dispositions de l’article précédent ne sont pas applicables à l’enfant marié.”
That was it. An unmarried minor child whose parent was reinstated in French nationality before 1994 became French automatically – regardless of where the child lived, and regardless of whether they were living with their parent.
After 1994: Habitual Residence Required
The loi n° 93-933 du 22 juillet 1993 repealed the CNF in its entirety and introduced new nationality provisions into the Code civil. The collective effect of a parent’s acquisition of French nationality is now governed by Article 22-1 of the Civil Code, which provides:
“L’enfant mineur dont l’un des deux parents acquiert la nationalité française, devient français de plein droit s’il a la même résidence habituelle que ce parent ou s’il réside alternativement avec ce parent dans le cas de séparation ou divorce.”
Two significant changes were introduced:
- A habitual residence requirement: the child must be living with the acquiring parent at the time of the reinstatement – or, in cases of separation or divorce, residing with that parent on an alternating basis.
- A mention requirement: for acquisitions by decree or declaration, the child’s name must be expressly mentioned in the decree or declaration (Article 22-1, paragraph 2).
A child who was not living with the reinstated parent – for example, one who remained abroad – no longer benefits from the collective effect under the post-1993 regime.
Practical Implications
This distinction carries significant consequences for nationality claims (demandes de CNF) brought today on the basis of a parent’s historical reinstatement.
If the parent was reinstated before 1 January 1994, the claimant need only establish:
- that they were under 18 at the date of the reinstatement decree,
- that they were unmarried at that date, and
- that their filiation with the reinstated parent was legally established at that date.
No evidence of cohabitation or habitual residence is required. Raising such a requirement would amount to applying the post-1993 regime retroactively, which is legally impermissible: French nationality law applies the rule in force at the date of the operative fact (tempus regit actum).
If the parent was reinstated on or after 1 January 1994, the claimant must additionally demonstrate habitual residence with the reinstated parent at the relevant date, and verify that their name was mentioned in the decree.
