Introduction

Marrying a French citizen as a foreigner is more than saying yes in front of the mayor. It is a three-to-six-month administrative journey, sometimes longer depending on your country of origin, with interviews, certified translations, consular stamps and multiple signatures. The city hall is not hostile: it applies the French Civil Code, which since the 2006 law has actively cracked down on so-called "white" or "grey" marriages of convenience.

This guide describes the real procedure as practiced in 2026, with the documents required by country of origin, realistic timelines, and the most common pitfalls. Whether you are Chinese, Moroccan, Algerian, Senegalese, Vietnamese or Brazilian, the framework is the same — only the consular details vary.

Step one: building the city hall file

You file your dossier at the mairie of your residence, your future spouse's residence, or a parent's residence (proof: three months of utility bills or rent receipts). Expect two or three appointments: one to collect the list of documents, one to deposit the complete file, one for the interview convocation.

Documents required from both spouses:

• Identity document (passport for the foreigner, ID card or passport for the French citizen)
• Proof of address less than three months old
• Birth certificate less than three months old (six months if issued abroad)
• List of witnesses (two to four, of legal age, with photocopies of their ID)
• Sworn declaration of single or non-remarriage status
• If previously married: divorce decree, final judgment, or death certificate of the previous spouse

Documents specific to the foreign spouse:

• Multilingual birth certificate (CIEC form, valid in most EU countries) or birth certificate translated by a court-sworn translator in France, apostilled or legalized depending on the country
• Certificate of custom (certificat de coutume): document from your country's consulate in France attesting that your national law permits this marriage and specifying conditions (age, parental authorization if any, default matrimonial regime)
• Certificate of marriage capacity: proof that you are free to marry under your national law

The certificate of custom maze: country by country

The certificate of custom is issued by your consulate or embassy in France. Timelines vary widely. Plan for two to four months in most cases, longer for some countries.

Wei, a Chinese national living in Lille, waited ten weeks because her hukou had not been authenticated in Beijing before she left. Karim, Moroccan, got his in three weeks in Bordeaux. Maria, Brazilian, centralized her papers in two months thanks to her cousin still in São Paulo.

The pre-marriage interview: the anti-fraud checkpoint

This is the step that most surprises foreigners. Since 2006, the civil registrar must interview the future spouses if there is any doubt about the sincerity of the project — and in practice, as soon as one spouse is foreign, the interview is nearly systematic.

You are summoned separately, sometimes the same day, sometimes at different dates. The interview lasts 20 to 45 minutes per person. You are then received together to verify the consistency of the accounts.

Typical questions:

• How did you meet? Exact date, place, context
• What is your future spouse's profession? Approximate salary?
• Who are their parents, siblings? Do you live together? Since when?
• What are their tastes (food, films, music)? What language do you speak at home?
• Your plans: children, real estate purchase, country of residence in five years
• Your residency status: under what visa did you come to France?

Consequence in case of doubt: the registrar refers the case to the public prosecutor, who has 15 days (renewable once) to authorize or suspend the marriage. A suspension can last up to two months. In 2024, about 0.9% of files were referred, and most were eventually validated.

Banns publication: ten days of public posting

Once the file is complete and the interview validated, the mairie publishes the banns: a marriage notice posted for at least ten days at the city hall of each spouse's residence. The marriage cannot be celebrated until that period has passed.

If one spouse lives abroad or in another French commune, the banns must also be posted there. The marriage date is set after, usually one to three months after the end of the banns (depending on hall and registrar availability).

The civil ceremony and reception

On the day, you arrive at the mairie with your witnesses. The ceremony lasts 20 to 40 minutes: reading of the file, civil code articles on spousal obligations, exchange of consents, register signature, livret de famille issued on the spot.

A religious ceremony may take place after the civil marriage (never before: that is a six-month prison offense for the cleric). The reception is free-form. Average 2026 budget for 50 guests in Paris: 8,000 to 18,000 €. Outside Paris, count 50% to 70% of that.

Effects of marriage: residency and citizenship

Marriage to a French citizen opens two rights, but not immediately:

• Residency permit "vie privée et familiale": granted to the foreign spouse after proof of an effective shared life of at least six months on French territory (utility bills, leases, joint tax return). First card valid one year, renewable, then a two-year multiyear card, then a ten-year resident card.
• French citizenship by marriage: application possible after four years of marriage (five if you have not lived three years in France). You must prove uninterrupted shared life, B1 oral and written French, no criminal record, and pass an assimilation interview. Processing time 12 to 24 months in 2026.

Anti-fraud: white marriage, grey marriage, consequences

A white marriage is a marriage of convenience between two consenting people purely for the residency permit. A grey marriage is when the French spouse is deceived: believing in a sincere project, they later discover the other only sought papers.

Criminal penalties (article L823-11 CESEDA): up to five years in prison and 15,000 € fine. Marriage annulment, immediate withdrawal of the residency permit, OQTF (obligation to leave French territory), multi-year ban on returning.

Reports come mainly from family, neighbors, sometimes the deceived spouse. The prefecture cross-checks indicators: separate addresses on the joint tax return, no joint bank accounts, contradictory testimony at residency renewal.

Summary

• City hall file: personal documents + translated/apostilled birth certificate + certificate of custom + marriage capacity certificate
• Separate then joint interview nearly systematic for mixed couples
• Banns publication 10 days minimum, ceremony 1 to 3 months after

FAQ

My future French spouse lives abroad. Can we still marry at a French city hall?

Yes, provided one of you has a residence in France. The French citizen abroad may also marry at a French consulate in their country, but the dossier is heavier (apostille, foreign birth certificate translation, etc.).

Is a marriage contract necessary when one spouse is foreign?

Not mandatory. Without a contract, the default French regime is community of acquired property. If your national law provides another regime (e.g. Muslim separate-property regime, Chinese community regime), a notary contract (300 to 500 €) clarifies things to avoid conflict in case of divorce or inheritance.

How long does it take to get a residency permit after marriage?

You can apply right after the marriage, but the card is only issued after proof of six months of shared life in France. First card valid one year. Many prefectures grant a three-month receipt during processing, which authorizes you to work.

Can the mayor refuse to marry us?

The mayor may postpone the marriage if there is serious doubt and refer the case to the prosecutor. They cannot refuse arbitrarily. If you believe the decision is unjustified, you can take it to the judicial court (lawyer recommended, 1,200 to 2,500 €).

Can my parents living abroad come to the wedding?

Yes, they can apply for a Schengen "family event" short-stay visa at the French consulate in their country. You will need to provide a hosting attestation (request at city hall, 30 €), an invitation and a copy of the marriage convocation. Processing 2 to 4 weeks depending on country.
