PACS and Marriage in France: Why the U.S. Can't Issue the Document French Mairies Actually Want

This is a companion to our broader guide to France's Talent Passport, VLS-TS visas, and long-stay categories. This one is specifically about PACS and marriage, and it centers on a document that doesn't exist in the form French law expects, because the U.S. Embassy's own guidance says so directly: neither the Embassy nor any federal U.S. authority can issue a certificat de coutume or certificat de célibat, since American marriage records are managed at the state level, not federally. What exists instead is a substitute, and getting that substitute right, along with the documents that surround it, is where most French civil status filings actually fail.

The Certificat de Coutume Problem, and the Substitute the Embassy Provides

Every foreign national entering a PACS or marrying in France has to prove they're legally free to do so and that any prior marriage has ended, typically through a certificat de coutume, an affidavit of home-country law, and a certificat de célibat or capacité matrimoniale confirming single status. Because no single American authority can issue either document, the U.S. Embassy provides a specific substitute form instead: the Attestation tenant lieu de certificat de coutume et de célibat, a document you sign attesting you're free to marry or enter a PACS. Notably, this form does not require Embassy notarization by default.

Here's where it gets genuinely inconsistent, and it's worth knowing before you assume one path applies everywhere. France has more than 35,000 mairies, and each has developed its own procedure. Some accept the Embassy's attestation as signed. Others insist the signature be legalized at the Embassy or a U.S. consulate, at a $50 per-seal fee. Still others, according to attorneys who handle this regularly, only accept a certificat de coutume drafted by a U.S.-licensed attorney rather than the Embassy's own form. Confirm directly with the specific mairie handling your PACS or marriage which version they'll actually accept before you assume the Embassy's standard form is sufficient.

PACS Has One Additional Document Marriage Doesn't: The Certificat de Non-PACS

This is a genuine point of difference between the two paths worth knowing if you're choosing between them. A PACS specifically requires a certificat de non-PACS, confirming you're not already bound by an existing PACS, issued by the Service central d'état civil in Nantes and generally required to be less than three months old at filing. This document doesn't come up for a standard marriage at all, it's specific to the PACS process.

The Birth Certificate: Full Copy, Generally Under Six Months

French authorities generally want a copie intégrale, a full certified copy rather than an abstract, of your birth certificate, and it's commonly expected to be less than six months old at the time of filing. Interestingly, some guidance notes an exception for countries whose civil records aren't routinely updated after issuance, which may describe how U.S. birth certificates actually work in practice, but this is worth confirming with the specific mairie rather than assuming the exception applies to you by default.

This is a state document, authenticated by the Secretary of State of the state that issued it, and only that state. The EU's 2019 document exemption regulation and the UK's bilateral arrangement that waive apostille requirements for those countries' documents do not extend to the United States. A U.S. birth certificate needs the full apostille treatment regardless of what exemptions apply to other nationalities.

FBI Checks: It Depends Genuinely on Which Visa Category You're In

This is worth restating from our broader France guide because it applies here too. There's no single blanket FBI requirement across every French visa category. Retirees applying for the long-stay Visiteur visa commonly do need an apostilled FBI background check alongside their birth certificate. Students sometimes need one and sometimes don't, depending on the specific program and consulate. A single-status affidavit rarely comes up for a retiree visa on its own, it's specifically a marriage and PACS document. Confirm with your specific consulate what your category actually requires rather than assuming the PACS document list applies to an unrelated visa application.

Where an FBI check is required, it follows the same rule as everywhere else on this site: it's a federal document, authenticated by the U.S. Department of State, not any state Secretary of State.

Sworn Translation, and the Sequence That Avoids Paying Twice

Every apostilled document needs translation into French by a traducteur assermenté, a sworn translator registered with a French Court of Appeal, not a standard certified translator or a self-translation. Lists of registered translators are available through individual mairies or the Cour de Cassation's own website.

The sequence matters as much as who does the translating. Authenticate first, translate second. The apostille certificate itself needs to be part of what the sworn translator renders into French, so translating before the apostille is attached means the entire translated package has to be redone.

If You Marry or PACS Outside France

If the ceremony happens abroad rather than in France, expect to need the resulting marriage certificate or PACS record transcribed onto the French civil registers before applying for any residence permit based on that relationship. This transcription is a separate step from the initial document authentication and translation, and it needs to happen before, not alongside, a permit application that depends on it.

Where French Civil Status Filings Go Wrong

• Assuming the Embassy's standard attestation form satisfies every mairie, when many have their own specific preference, including some that want an attorney-drafted version instead

• Missing the certificat de non-PACS for a PACS specifically, a document marriage applications don't require

• Letting the birth certificate or certificat de non-PACS exceed their freshness windows, roughly six months and three months respectively

• Assuming an FBI check is universally required, when it depends heavily on the specific visa category and consulate

• Sending an FBI report to a state office, which cannot authenticate a federal document

• Using a translator not registered with a French Court of Appeal

• Translating documents before the apostille is attached, requiring the work to be redone

• Skipping transcription for a marriage or PACS that occurred outside France
