Getting married in France as a non-resident: the 40-day problem

The rule that changes everything

To marry legally in France, at least one of you must demonstrate 30 to 40 days of continuous residence in the commune where you are marrying — and that residence has to be established BEFORE the banns are published. It is not a formality you satisfy by booking a hotel for the week of the wedding.

Add the ten-day publication of banns on top, and a foreign couple with no prior connection to France is looking at roughly forty to fifty days between arriving and being able to hold the ceremony. For most couples that is not a wedding plan; it is a sabbatical.

If you do qualify: the mairie process

The route below applies if one of you is French, is resident in France, or is prepared to establish that 30–40 day residence. The competent authority is the mairie — the town hall — of the commune itself.

1. Contact the mairie months ahead — There are more than 35,000 mairies in France and each has developed its own procedure and document list. This is not a national checklist you can look up once.
2. Establish residence — 30–40 days in the commune, depending on which one.
3. Submit the dossier de mariage — Typically 30–40 days before the intended date, to leave time for the banns and the interview.
4. The audition — A pre-wedding interview with a registrar. Both of you, sometimes separately. It is a check that the marriage is genuine and it is a normal part of the process for foreign couples.
5. Publication des bans — Posted at the mairie for ten days. Once they have elapsed you may marry any time within the following year.

The documents

• Passports and full birth certificates — recently issued, with sworn French translations.
• Certificat de coutume — an affidavit, in French, from a lawyer or public officer in your home country explaining that country's marriage law — so both you and the French administration know whether the marriage will be recognised back home.
• Certificat de célibat — confirming you are not already married. From a civil registry at home, your embassy in France, or a notary.
• Proof of domicile — for the commune. This is the residency evidence.
• Witnesses’ details — two to four, with copies of their ID.
• Divorce decree or death certificate — if either of you was married before.

Coutume and célibat are frequently confused. The certificat de coutume explains your home country's law; the certificat de célibat states that you personally are free to marry. Some mairies want both, some accept a certificate of matrimonial capacity instead. Ask yours, specifically, in writing.

So should you marry in France?

If one of you is French or lives in France, yes — the process is well-trodden and the mairies handle it constantly. If neither of you has a connection to France, the honest answer is that you should plan a French celebration and marry legally at home.

That is not a lesser wedding. It removes the single largest constraint on the date, the venue and the guest list, and it costs nothing but a registry office appointment in your own town. Countries that welcome non-resident marriages — Portugal, Greece, Italy — are the alternative if the legal ceremony itself has to happen abroad.
