In France, only the marriage celebrated at the town hall, before the civil registrar, has legal effect. The nikah — the religious marriage contract — binds the spouses before their community and their faith, but on its own it creates no bond that French law recognises. French criminal law also governs the order of the two celebrations: a minister of religion who habitually performs religious marriages without a prior civil marriage certificate commits an offence. Hence the order most couples follow: the town hall first, the religious ceremony afterwards, on the same day or later. Belgium, the Netherlands and Germany each have their own rules on this point, which this article does not cover.
Why does the civil marriage come before the nikah in France?
The principle is old: since the early nineteenth century, French law has required the civil marriage to precede any religious ceremony. Today it is carried by article 433-21 of the Penal Code. In its version in force, resulting from the law of 24 August 2021, it punishes with one year's imprisonment and a €7,500 fine "any minister of religion who habitually performs religious marriage ceremonies without having been shown the marriage certificate previously received by the civil registrars".
Three elements of this text deserve to be read as they are written:
- It targets the minister of religion, that is, the person who celebrates — not the future spouses, nor their families, nor the witnesses.
- The habitual character is a constituent element of the offence. A ministerial answer published by the Senate recalls that the text penalises a repeated practice.
- What it requires is proof of the prior civil certificate: concretely, showing the marriage certificate or the family record book (livret de famille).
In practice, many mosques and imams therefore ask for the civil marriage certificate before celebrating a nikah. That is not excessive zeal: it is the application of a text that concerns them directly.
Note. This text does not say that the nikah is "illegal", and it provides no penalty for a couple who marry religiously without going through the town hall. What French law does is something else: it ignores that marriage. For the State, the two people are not married — with all the consequences described below.
What are the conditions of civil marriage in France?
The Civil Code sets the substantive conditions. Two of them come up in every situation:
- Age. "Marriage may not be contracted before the age of eighteen" (article 144). An exceptional dispensation, granted by the public prosecutor for serious reasons, exists in the Code, but it concerns rare cases.
- Consent. "There is no marriage where there is no consent" (article 146). That consent must be free and genuine; the civil registrar has a duty to make sure of it, notably during the prior interview provided for by article 63.
Other conditions are checked by the town hall on the basis of the file — for instance the absence of a previous marriage that has not been dissolved. The "Marriage in France" sheet on service-public.fr gives the up-to-date list.
How do the formalities at the town hall work?
- The file. It is submitted to the town hall of the commune where one of the future spouses, or one of their parents, has their domicile or residence. The documents required are listed on service-public.fr; they vary with each person's situation.
- The interview. Article 63 provides for a joint interview of the future spouses by the civil registrar, before the banns are published. The registrar may waive it if the file leaves no doubt about the intention to marry.
- The publication of banns. It is posted at the door of the town hall at least ten days before the celebration, at the town hall of the place of marriage and at that of the domicile or residence of each future spouse (article 63).
- The celebration. The marriage "shall be celebrated publicly during a republican ceremony by the civil registrar" of the competent commune (article 165). The witnesses sign the certificate.
- The marriage certificate. It is this — and the family record book that goes with it — that proves the marriage, including to the imam or the mosque.
What does a nikah on its own produce, and not produce?
A nikah celebrated without a civil marriage produces what the community and the faith of the spouses recognise in it. It produces nothing in French law. That applies to everything the Civil Code attaches to marriage "by the sole effect of marriage": the spouses' reciprocal duties — respect, fidelity, support, assistance (article 212) —, the contribution to the expenses of the marriage (article 214), the protection of the family home (article 215).
It also applies to the areas that depend on the status of spouse: inheritance, parentage, taxation, the right of residence of a foreign spouse. In each of these areas, a couple united only religiously is treated by the law as an unmarried couple, and falls under the rules applicable to unmarried people. The detail of those rules goes beyond this article; it is learned from a notary, a lawyer or the competent public services.
| Question | Civil marriage | Nikah on its own |
|---|---|---|
| Does it exist for the French State? | Yes | No |
| Duties and rights of spouses under the Civil Code | Yes, by the sole effect of marriage | No |
| Matrimonial property regime | Yes: the statutory regime, or a contract before a notary | None |
| Proof of the marriage | Marriage certificate, family record book | No civil proof |
| Religious value | A religious question, outside the scope of this article | Yes, for those who contract it |
Marriage contract, matrimonial regime, Islamic contract: what are we talking about?
The words "marriage contract" refer to two different realities depending on whether one is speaking of French law or of the religious marriage.
In French law, the marriage contract is an agreement about the spouses' property. In the absence of a contract, a statutory regime applies automatically — community of property limited to acquisitions after marriage (communauté réduite aux acquêts) — because "the law governs the conjugal association, as regards property, only in the absence of special agreements" (article 1387). Spouses who want another regime choose it by deed before a notary, prior to the celebration. Choosing a regime is a property decision to be prepared with that professional; no blog article can make it for you.
In the religious marriage, the contract (ʿaqd an-nikāḥ) rests on the consent of both parties, witnesses, and the mahr — the marriage gift owed to the wife herself. The Qur'an makes it a right of the woman, given willingly (sura 4, verse 4). According to the schools, a guardian (wali) also takes part; that point is dealt with in a dedicated guide. This contract may include clauses agreed between the spouses.
The two contracts are not mutually exclusive: a couple can marry civilly under a regime chosen before a notary, then contract a nikah with an agreed mahr. On the other hand, the value a French judge would give to a given clause of a religious contract is a question of law that depends on each case, and has no place here.
What if one of the future spouses is a foreign national, or the marriage takes place outside France?
Specific formalities exist in both situations. When a future spouse is a foreign national, the town hall may ask for documents specific to that nationality — for instance a certificate of custom (certificat de coutume) issued by the consulate — and require a translation of documents written in another language. When a French national marries abroad, steps with the French consulate apply before and after the celebration for the marriage to be recognised in France.
These steps vary by country and situation; the town hall, the consulate concerned and the official pages of service-public.fr and France Diplomatie are the only up-to-date sources.
In what order should you organise things?
| Step | Civil side | Religious and family side |
|---|---|---|
| Getting to know each other and deciding | — | Muqabala, then khitba (proposal of marriage) |
| Preparing the file | Documents, submission to the town hall, interview | — |
| Waiting for publication | Banns posted for at least ten days | — |
| Getting married | Celebration at the town hall, marriage certificate | — |
| Contracting the nikah | Showing the civil certificate to the minister of religion | Nikah, the same day or later |
| Celebrating | — | Meal, walima, according to the families |
The nikah can follow the town hall by a few hours or several months: the law imposes no delay between the two, only the order.
Frequently asked questions
Is a nikah before the town hall forbidden in France?
Criminal law forbids the minister of religion to celebrate it habitually without a prior civil certificate; he is the one who incurs the penalty. The spouses incur nothing, but their nikah on its own has no legal effect. In practice, most imams and mosques refuse to celebrate without the marriage certificate.
Can an imam refuse to celebrate because the civil marriage has not taken place?
Yes. In doing so, he is applying a text that concerns him directly. A refusal of that kind is not a judgement on the couple: it is the consequence of the civil-then-religious order laid down by French law.
Is a "religious-only" marriage a real marriage?
On the religious level, the validity of a nikah depends on the conditions set by the Islamic legal schools; that is not the subject of this article. On the civil level, the answer is clear-cut: without a marriage at the town hall, French law recognises no marriage.
