Marriage paperwork with a Russian or Ukrainian partner: documents, town hall, transcription

What this guide covers, and what it does not

The information below draws on service-public.gouv.fr pages consulted on November 6, 2026. It describes the most common situation: a French citizen (or a resident of France) marrying a Russian or Ukrainian national. Rules change and the town hall keeps some discretion: the exact file is given to you by the town hall where the wedding will take place, and it prevails. This text replaces neither that town hall, nor a lawyer, nor a consulate.

If you live in Belgium, Switzerland or Quebec, the principle is the same (a file filed with the competent civil registrar), but the documents, deadlines and ceremony formalities depend on local law. Contact the municipal administration or civil registry of your place of residence before you start collecting papers.

Marrying in France or abroad?

The choice affects what follows.

	Wedding in France	Wedding abroad
Where to file	Town hall of the commune where one of the future spouses (or a parent) lives	Local authorities of the country, under its law
Formality afterwards	Family record book and French certificate	Transcription of the certificate in French registers by the consulate
Advantage	Known procedure, one applicable law	Ceremony in the future wife’s home country; local deadlines and formalities

For a wedding held abroad, service-public points out that the certificate must then be transcribed with the French consular authorities to take effect in France, a point confirmed by the page on the residence card for a French citizen’s spouse. Given the situation in Russia and Ukraine (see the guide First trip and first meeting), many couples choose a wedding in France, or in a third country under local rules.

Documents usually requested for a wedding in France

The service-public page “Mariage en France” lists the documents each of the two future spouses must provide. The main ones:

1. ID (original and photocopy): identity card, passport, residence permit depending on the situation;
2. recent proof of address or residence. Mobile phone bills, bank details slips and sworn statements are not accepted;
3. a birth certificate with parentage, recent. For a French certificate, the validity period (under 3 months) is counted from the date the file is filed, not the ceremony;
4. documents specific to your family situation (divorce judgment, death certificate of a previous spouse, etc.).

For the foreign future spouse, the town hall may ask for documents linked to her nationality. Service-public cites in particular:

• a certificate of custom, usually issued by the embassy or consulate of the country concerned, attesting that the person may marry under their law;
• failing that, a sworn statement of majority, single status and legal capacity, if the town hall accepts it;
• for any document issued abroad and written in a foreign language, a translation by a sworn translator. The town hall will also tell you whether a legalisation or apostille is required for a given certificate.

The steps in order

1. Call the town hall

   Book an appointment before buying anything: the list of documents and the validity period of certificates depend on the commune.

2. Request the certificates

   Your birth certificate; the future wife's certificates from her country's authorities or her consulate in France.

3. Have them translated

   By a sworn translator, without waiting for the last week: the validity period runs from filing.

4. File the application

   Both future spouses attend the town hall. A joint or separate interview may be requested to check the reality of the life plan.

5. Publication of banns, then the ceremony

   The wedding is held publicly at the town hall. You receive a family record book.

6. Plan what comes next

   Visa, residence card, possible nationality declaration: see the guide on bringing your spouse to France or Quebec.

The interview and the sincerity check

When one of the future spouses is a foreign national, the civil registrar may speak with the couple to make sure the marriage is freely consented to and reflects a genuine intention to marry. This is not a hostile formality: it exists to protect people, notably against forced marriages and so-called “marriages of convenience”. Bring concrete evidence of your relationship (exchanges, travel tickets, dated photos, statements from relatives) rather than generalities. If you have never met the person in the flesh, the town hall will notice, and a prior meeting is in practice essential.

Consent and substantive rules

Whatever the nationality, marriage requires the free consent of both people, adulthood, no existing marriage and compliance with each person’s capacity rules. For a foreign national, her country’s law determines certain personal conditions, hence the certificate of custom. If either has been married before, documents proving the end of the previous union (judgment, death certificate) are generally required, with translation.

Costs, deadlines, pitfalls

• Civil status certificates from Russia or Ukraine may take time depending on the authorities and the wartime context. Allow several weeks, or more, and keep copies of everything.
• Never pay an intermediary who promises to “guarantee” the marriage or a visa: only public services decide, and their forms are free or at official rates.
• Check the validity date of each certificate before having it translated: a certificate that has expired at filing means starting over.
• Keep the originals and provide copies unless told otherwise.

After the wedding: name, family book, nationality

Marriage does not automatically change nationality. The foreign spouse of a French citizen may, under conditions, make a declaration of nationality by marriage; service-public details these conditions (length of marriage, shared life, knowledge of French) on its page Declaration of French nationality by marriage. This step comes much later and does not replace the residence procedures described in the next guide.

Special cases to plan for

• Divorced or widowed: documents proving the end of the previous marriage are requested, translated if needed. If the judgment was issued abroad, ask the town hall whether it must be recognised or legalised.
• Children: a child of the future wife is not part of the marriage file, but her status (parental authority, the other parent’s consent to leaving the country) will matter later in the process. Ask early.
• Marriage contract: in France, without a contract, the default regime applies (community of acquests). If you want another regime, a contract is signed with a notary before the ceremony. It is a conversation for the couple, not a sign of distrust.
• Names: first names and surnames must be spelled consistently from one document to the next (transliteration from Cyrillic). A discrepancy between passport and birth certificate must be explained before filing.
• Deadlines and holiday calendar: plan the ceremony and consular appointments with administrative closures in mind.

Belgium, Switzerland, Quebec: where to start

Each territory has its own civil registry and deadlines. To save time, start from the local official source:

• Belgium: the federal portal belgium.be points to the municipal administration competent for marriage;
• Switzerland: the portal ch.ch presents marriage procedures and points to the civil registry office of the canton of residence;
• Quebec: the Directeur de l’état civil gives information on celebrating a marriage or civil union and on authorised officiants.

In all three cases, ask in writing for the list of documents and the validity period of each, then compare it with what the consulate of your future wife’s country asks.

A checklist before filing

• ID of each person, valid;
• proof of address meeting the town hall’s requirements;
• recent birth certificates, with parentage;
• documents showing the foreign future spouse’s capacity to marry (certificate of custom or equivalent accepted by the town hall);
• sworn translations of all documents in a foreign language;
• divorce judgment or death certificate where relevant;
• contact details of two or four witnesses, if the town hall requires them;
• a digital copy of each document, filed by validity date.

Frequently asked questions about the file

Can you marry someone you have only met online? Nothing prohibits having met at a distance, but the interview and sincerity check rely on concrete evidence: an in-person meeting, and in practice several, is essential.

Must the future wife be in France for the wedding? Generally yes: the future spouses appear at the town hall. If she lives abroad, she will need to enter France with a suitable visa; the town hall or prefecture will tell you which.

How long should you allow? No duration is guaranteed: it all depends on how quickly certificates and translations are obtained and on the town hall’s calendar. Allow several months and book neither a venue nor a trip before a date is confirmed.

Can you use a translator of your choice? For official documents, the town hall requires a sworn translator; ask for the list of experts approved by the court of appeal of your region.

In short

• the town hall of the wedding sets the exact list of documents;
• plan for sworn translations, a certificate of custom or equivalent, and check validity periods;
• a wedding held abroad must be transcribed with the French consular authorities;
• no official procedure can be “guaranteed” for a fee.

Next: bringing your spouse to France or Quebec.
