Finding the marriage date of a person in France requires knowing what type of document to request, which administration to contact, and, in some cases, how to utilize peripheral documents when direct access is locked. The process varies depending on the age of the union and the relationship to the individuals involved.
Marginal notes on the birth certificate: the most reliable lead after a divorce
When a marriage has been dissolved by divorce, the marriage certificate itself becomes difficult to obtain for a third party without standing. The most direct route then goes through the marginal notes on the birth certificate of each ex-spouse.

Under French law, any modification of civil status (marriage, divorce, death of a spouse) is recorded in the margin of the birth certificate. The note specifies the date of the marriage, the municipality of celebration, and the identity of the spouse. After a divorce, a second note is added with the date of the final judgment.
For a genealogist or an heir, requesting a birth certificate extract with parentage is sufficient to retrieve this information, provided they can justify a direct family relationship (ascendant, descendant) or have a power of attorney. A third party without family ties can only obtain an extract without parentage, which does not include the marginal notes.

We recommend submitting the request to the town hall of the place of birth, including online when the municipality offers an e-service. You can also consult a marriage notice in Saint-Nazaire on Mariages du Monde to complement your initial research.
The birth certificate remains accessible even when the marriage certificate is locked, making it the key document for reconstructing a post-divorce marital chronology.
Communication deadlines for marriage certificates in France
Marriage certificates older than 75 years are freely accessible to anyone, without justification of family ties. This rule applies both in reading rooms at departmental archives and on online digitization portals.
For certificates less than 75 years old, the rules change radically:
- The individuals concerned by the certificate (the spouses themselves) can obtain a full copy upon simple request at the town hall of the place of celebration.
- Direct ascendants and descendants can request a full copy by justifying their parentage.
- Third parties are only entitled to an extract without parentage, which mentions the date and place of the marriage but omits information about the spouses’ parents.
Several pilot departments, including Nord and Bas-Rhin, have accelerated the digitization of their civil status registers post-1945. This trend is gradually opening up free online access to recent marriage certificates for direct heirs, without the need for postal correspondence.
Decennial tables and indexing: finding a marriage without knowing the municipality
The main obstacle often remains the ignorance of the place of celebration. Without this information, it is impossible to send a request to the correct town hall. The decennial tables then become the most effective research tool.
These tables, established for periods of ten years in each municipality, list all recorded birth, marriage, and death certificates in alphabetical order. For the 19th century and the early 20th century, they are largely digitized on departmental archive websites.
AI indexing on Filae and Geneanet
Since the end of 2025, automated AI indexing of decennial tables on platforms like Filae and Geneanet has significantly reduced the number of unsuccessful searches. Where it was once necessary to manually sift through dozens of handwritten pages, a name search engine now directly links to the image of the relevant register.
We observe that this advancement particularly benefits searches for common surnames, which were previously buried in volumes of several hundred pages. For a rare name, manual searching in the tables remains quick, but AI indexing eliminates the risk of skipping a line during the review.
Consular civil status acts: specific constraints for marriages celebrated abroad
For a marriage celebrated at a French consulate or recorded at the Central Civil Status Service in Nantes, the procedure differs from the standard municipal circuit. The digital form for requesting consular acts is closed until mid-2026 due to staff shortages, requiring requests to be sent exclusively by postal mail.
Processing times are currently doubled compared to normal. We recommend anticipating any request by at least two months if the marriage certificate was issued or recorded by a consular post.
Marginal note: a quicker alternative
If one of the spouses was born in France, the consular marriage note is also recorded in the margin of their birth certificate held by their municipality of birth. Taking this route allows bypassing the congestion at the Central Civil Status Service and obtaining the marriage date in a few days instead of several weeks.
Parish registers: finding a marriage prior to 1792
Before the establishment of secular civil status in 1792, marriages were recorded in parish registers maintained by the parish priest. These registers, mandatory since the Ordinance of Villers-Cotterêts in 1539, mention the date of the ceremony, the names of the spouses, their parents, and witnesses.
Collections typically begin in the 16th or 17th century depending on the diocese. Almost all of these registers are now digitized and freely accessible on departmental archive portals. The difficulty lies less in accessing the document than in the paleographic reading of the handwritten acts, often written in Latin for the oldest ones.
Searching for a marriage date in France relies on a combination of administrative procedures and digital tools, the effectiveness of which depends on the time of the marriage and the relationship with the individuals concerned. For recent unions made opaque by a divorce, the marginal notes on the birth certificate remain the most accessible route and the least subject to communication restrictions.
