Documents You Need (with Timeline)

Getting legally married in France as a foreign couple requires a specific set of documents submitted to the mairie (town hall) of the commune where the wedding will take place. The process takes longer, costs more, and involves more steps than most international couples expect, and the requirements differ depending on whether you hold a British, American, Australian, or other passport.

Based on destination weddings featured on French Wedding Style over 15 years, the gap between what couples expect and what the process requires is consistently the biggest source of stress. This guide lists every document, explains the timeline for obtaining them, and flags the nationality-specific complications that cause delays, as part of our complete guide to getting married legally in France.

Key Takeaways

The document requirements for a legal marriage in France as a foreign couple follow a core universal checklist supplemented by nationality-specific extras that vary in cost, complexity, and processing time. All couples need birth certificates, proof of identity, proof of address, a certificat de coutume or equivalent, and sworn French translations of every non-French document. UK couples require a Certificate of No Impediment with a 28-day notice period plus an FCDO apostille at £75 taking 15 to 20 working days. US couples face the most complex route because the US Embassy cannot issue a certificat de coutume. Instead, US citizens sign a self-attestation form available on the Embassy website, which does not require notarization in most cases. Total US paperwork costs run $600 to $1,200 (€550 to €1,100). Starting the paperwork 6 to 9 months before the wedding date is consistently the most important action, because the sequential nature of the process does not compress.

• The core document list is the same for all nationalities: birth certificates, proof of identity, proof of address, certificat de coutume (or equivalent), and a sworn French translation of everything.
• UK couples need a Certificate of No Impediment (CNI) from the UK registry office (28 days' notice), plus an FCDO apostille (£75, 15 to 20 working days).
• US couples face the most complex process: the US Embassy cannot issue a certificat de coutume. Instead, US citizens sign a free self-attestation form from the Embassy website. Some mairies require Embassy notarization at $50 per seal. Total US paperwork: €550 to €1,100.
• All foreign-language documents must be translated by a traducteur assermenté (sworn translator), costing €30 to €60 per page.
• Start the paperwork 6 to 9 months before the wedding. Birth certificates must be less than 3 months old if born in France, or less than 6 months old if born outside France (including UK, US, and Australian citizens).

What Documents Do All Foreign Couples Need?

Every foreign couple marrying legally in France must submit a dossier de mariage to the mairie of the commune where the wedding ceremony will take place. A dossier de mariage is the complete file of legal documents required by the French authorities to authorise a civil marriage.

The core documents are the same regardless of nationality: a full birth certificate (acte de naissance intégral) for each partner, less than 3 months old at the time of submission for those born in France, or 6 months for those born outside France (including UK post-Brexit, US, and Australian citizens), valid passport or national identity card, proof of current address (justificatif de domicile) such as a utility bill or bank statement, a certificat de coutume or equivalent document confirming that neither partner is already married and that the marriage would be recognised in their home country, and a sworn French translation (traduction assermentée) of every document not originally in French. The dossier must be submitted to the mairie at least 30 to 40 days before the planned ceremony date, depending on the commune, to allow time for the publication of banns (annonce des bans) and the pre-wedding interview (audition). The specific residency, freshness, and documentation requirements vary by nationality, which is why UK, US, and Australian couples each face a different preparation timeline.

What Is the Timeline for Preparing the Paperwork?

The document preparation timeline for a legal marriage in France should begin 6 to 9 months before the wedding date, not because every document takes that long but because delays at any step cascade into the steps that follow. The total sequential process for UK couples, who face the most layered requirements, takes 10 to 14 weeks from CNI application to dossier submission. For US couples, the multi-state apostille process adds 2 to 8 weeks depending on the states involved. Birth certificates that expire before the dossier is submitted must be reissued.

Apostilles that take longer than expected push back translation deadlines. A mairie that requests an additional document not on the standard list adds weeks to the process. Starting early builds a buffer that absorbs these delays without threatening the wedding date. The standard timeline for UK couples looks like this.

What Additional Documents Do UK Couples Need?

British couples marrying in France after Brexit face a more complex document process than they did as EU citizens, and the specific requirements have changed since 2021. The core additional requirement is a Certificate of No Impediment (CNI), issued by the local register office in the UK. Applying for a CNI requires 28 days' notice, and the certificate is valid for only 3 months from issue. Once obtained, the CNI must be apostilled by the FCDO (Foreign, Commonwealth and Development Office) at a cost of £75, which takes 15 to 20 working days for standard processing.

The apostilled CNI then requires sworn French translation by a traducteur assermenté before submission to the mairie. This sequential process (apply → wait 28 days → receive → apostille → wait 15 to 20 days → translate → wait 2 weeks → submit) means UK couples must start the CNI process at least 4 to 5 months before the dossier submission deadline. Total cost for the full UK paperwork process including CNI, FCDO apostille, birth certificate reissue, and sworn translations: approximately £400 to £800 (€500 to €1,000). For the complete UK-specific process, see our detailed guide to UK couples getting married in France.

What Additional Documents Do US Couples Need?

American couples face the most complex paperwork of any nationality because the US Embassy in Paris cannot issue a certificat de coutume, the standard document that French mairies require to confirm a foreign marriage would be recognised in the couple's home country. Instead, US citizens sign a self-attestation form ("Attestation tenant lieu de certificat de coutumes et de célibat") available on the US Embassy website. This form does not require Embassy notarization in most cases. The signature is legalized at the local French mairie with a valid US passport.

However, some mairies, particularly those in communes with fewer international weddings, may not accept the self-attestation without Embassy notarization. In those cases, appointments are available at the US Embassy in Paris or the US Consulate General in Marseille or Strasbourg, at a fee of $50 per notarial seal. Contact the specific mairie first and confirm in writing whether they accept the self-attestation. US apostilles are issued by the Secretary of State in the state where the document was issued, not by a central federal office. A couple where one partner was born in California and the other in New York must apply to two different state offices. Processing times and fees vary by state. Total cost for full US paperwork: approximately $600 to $1,200 (€550 to €1,100). For the complete US-specific process, see our guide to American couples getting married in France.

What About Australian and New Zealand Couples?

Australian couples can obtain a Certificate of No Impediment to Marriage from the Australian Embassy or Consulate in France at a cost of AUD 181, with processing taking 2 days to 4 weeks depending on the embassy's workload. New Zealand couples follow a similar process through the NZ Embassy. Both nationalities require birth certificates less than 6 months old (the non-EU standard), apostilled by the relevant national authority and translated into French by a sworn translator.

The overall process is simpler than the US pathway but requires the same level of advance planning due to embassy processing times and the need for sworn translations. Total cost: approximately A$400 to A$800 (€250 to €500). For the complete ANZ process, see our guide to Australian and NZ couples getting married in France.

How Much Does the Legal Paperwork Cost in Total?

The total cost of legal paperwork for a civil marriage in France varies by nationality but follows a predictable pattern: €500 to €1,000 for UK couples, €550 to €1,100 for US couples, and €300 to €600 for Australian and New Zealand couples. Sworn translations by a traducteur assermenté represent the largest single expense for most nationalities at €30 to €60 per page across 6 to 10 pages of documents, totalling €180 to €600. US couples face the highest overall costs because the absence of an Embassy-issued certificat de coutume creates additional complexity with the self-attestation process and multi-state apostille requirements that British and Australian couples do not encounter. These costs are rarely factored into initial wedding budgets because they sit outside the venue and vendor quotes that most couples use as their starting framework.

• Sworn translations are the largest single expense for most couples, at €30 to €60 per page for 6 to 10 pages of documents
• The remaining costs are nationality-specific fees for certificates, apostilles, and the certificat de coutume or equivalent
• These costs are rarely factored into initial wedding budgets because they sit outside the venue and vendor quotes that most couples use as their starting framework
• US couples face the highest total due to the additional complexity of the self-attestation process and multi-state apostille requirements

These costs are rarely included in wedding budget guides, which is why they appear as a surprise. Across the 400+ venues listed on French Wedding Style, these costs are rarely included in the initial budget estimate from either the couple or the venue. Add them to your planning budget from the start. A recommended wedding planner in France can handle much of the paperwork coordination, recommend sworn translators, and liaise with the mairie on your behalf, which is particularly valuable for couples who do not speak French.

5 Avoidable Errors When Preparing Your French Wedding Paperwork

The foremost common mistake is starting the process too late. Couples who begin the paperwork 3 months before the wedding discover that the sequential nature of the process (certificate, then apostille, then translation, then submission, then banns, then interview) does not compress well. Each step depends on the previous one completing, and a delay at any point pushes every subsequent deadline.

For UK couples, the CNI alone requires 28 days' notice plus 15 to 20 working days for the FCDO apostille before translation can even begin. For US couples, multi-state apostille processing can add 2 to 8 weeks depending on the states involved. Starting at 6 to 9 months provides the buffer that absorbs unexpected delays, including mairie requests for additional documents, translator availability, and postal delays, without threatening the ceremony date.

In the same vein, couples assume the official service-public.fr list is the complete list. Individual mairies can and do request additional documents beyond the national standard. Some communes require a certificat de célibat (certificate of single status) as a separate document from the CNI.

Others request utility bills in the commune's jurisdiction to satisfy the residency requirement, which destination couples cannot provide. Contacting the specific mairie and getting their requirements in writing before ordering any documents prevents wasted time and expense on the wrong paperwork. From the hundreds of real weddings we have featured, the couples who had the smoothest paperwork experience were those who contacted the mairie 9 months out and received a written requirements list.

What makes this worse, specific to US couples, is not confirming with the mairie whether they accept the self-attestation form from the US Embassy website. The Embassy cannot issue a certificat de coutume, so US citizens sign a self-attestation instead. Most mairies accept it, but some require Embassy notarization at $50 per seal, which means scheduling an in-person appointment in Paris, Marseille, or Strasbourg. Learning this at 3 months out creates a timing crisis that is entirely avoidable with early research. See how this couple brought this to life at Château de Varennes in Burgundy.

The sister mistake is not timing the birth certificate order correctly. Birth certificates must be less than 3 months old (born in France) or 6 months old (born outside France, including post-Brexit UK) at the time of submission to the mairie. Our guide to how a French wedding planner navigates the paperwork process for you explains the specifics. Ordering them 9 months before the wedding means they will expire before submission. Order them at 7 to 8 months out, targeting a submission window of 3 to 4 months before the ceremony.

Frequently Asked Questions

How far in advance should I start the marriage paperwork for France?

Start 6 to 9 months before the wedding. The process is sequential: each step (certificate, apostille, translation, submission, banns, interview) depends on the previous one. Starting at 3 months does not leave enough buffer for delays. UK couples should begin the CNI process at least 5 months before the dossier submission deadline due to the 28-day notice period plus 15 to 20 working days for the FCDO apostille.

How much do sworn translations cost for a French marriage?

A traducteur assermenté charges €30 to €60 per page. A typical marriage dossier requires 6 to 10 pages of translated documents, totalling €180 to €600. Translations must be performed by a translator officially registered with a French Court of Appeal. Translations done by non-registered translators, even if certified in the UK or US, may not be accepted by the mairie.

Can US couples get a certificat de coutume from the US Embassy?

The US Embassy in Paris cannot issue a certificat de coutume. Instead, US citizens sign a self-attestation form available on the Embassy website, which does not require notarization in most cases. The signature is legalized at the local French mairie with a valid US passport. Some mairies, particularly in communes with fewer international weddings, may require Embassy notarization at $50 per seal. Contact the specific mairie and confirm their requirements in writing before starting the process.

What is the residency requirement for getting married in France?

At least one partner must have a connection to the commune where the marriage will take place, typically demonstrated through 30 to 40 days of continuous residency. The exact requirement varies by commune. Some mairies accept a venue booking contract as evidence of temporary residence. Others require utility bills or a rental agreement in the commune. Destination couples should confirm the specific requirement with their mairie before beginning the process.

Do I need to get married at the mairie before the venue ceremony?

In France, only the civil ceremony at the mairie creates a legally recognised marriage. The symbolic ceremony at the venue, while emotionally significant, has no legal standing. The civil ceremony must take place before or on the same day as the symbolic ceremony. Many couples hold the civil ceremony on a weekday before the main wedding day, keeping the symbolic ceremony at the venue as the centrepiece event.

Should I just marry legally at home and have a symbolic ceremony in France?

This is the approach taken by 80 to 90% of foreign couples marrying in France. It eliminates all French paperwork requirements and allows the couple to focus entirely on the celebration. The symbolic ceremony at the venue creates the same celebration your guests experience and remember. If the administrative process feels unmanageable, marrying legally at home before or after the France trip is the pragmatic and widely accepted approach.
