Apostille for Belgium

By Frank MetayerUpdated August 16, 2026

Sending a U.S. document to Belgium — an FBI background check for a long-stay visa, a diploma for a work permit, or a birth certificate and single-status affidavit to marry at a Belgian commune — runs through a single apostille rather than the older embassy legalization. Belgium has been a member of the Hague Apostille Convention since it entered into force there on February 9, 1976, so a U.S. public document needs only one apostille from the correct U.S. authority — not authentication by a Belgian embassy or consulate. Membership can change, so confirm the current status on the HCCH status table before you file. What sets Belgium apart from most destinations is the step that comes after the apostille: the language your certified translation must be in depends on which part of the country your document is headed to.

That regional-language rule is the detail that trips people up, so this guide leads with it — Dutch in Flanders, French in Wallonia, French or Dutch in bilingual Brussels, and German in the eastern German-speaking Community around Eupen — before walking through the federal-versus-state question that decides who issues your apostille, the documents Belgian communes and immigration offices most often ask for, and the order of steps that keeps a marriage or residence file from bouncing back. Everything below reflects the process as of 2026. Because treaty membership, government processing times, and each commune's document rules can change, confirm the specifics with the Belgian authority receiving your document before you file.

Key takeaways

As of 2026, Belgium is a Hague Apostille Convention member (in force since February 9, 1976), so U.S. public documents take an apostille — not embassy or consular legalization. Confirm the current status on the HCCH status table before filing.
Belgium has three official languages, and the translation you need is set by region, not by preference: Dutch in Flanders, French in Wallonia, French or Dutch in bilingual Brussels, and German in the eastern German-speaking Community around Eupen and Sankt Vith.
Route each document by its issuer: an FBI background check and other federal records go to the U.S. Department of State, while birth and marriage certificates, diplomas, and single-status affidavits go to the Secretary of State of the state that issued or notarized them.
Many Belgian communes and courts require the translation to be done by a sworn translator (traducteur juré / beëdigd vertaler / vereidigter Übersetzer) registered with a Belgian court — so confirm who is allowed to translate before you commission one.
The most common Belgium job is a marriage file: an apostilled birth certificate plus an apostilled single-status affidavit, each then translated into the commune's regional language — apostille first, translate second.

Does Belgium Accept a U.S. Apostille?

Yes. Belgium is a Contracting Party to the Hague Apostille Convention, which entered into force for Belgium on February 9, 1976. That means a U.S. public document bound for Belgium needs a single apostille certificate from the competent U.S. authority — not the older, multi-step consular or embassy legalization. Once the apostille is attached, Belgian authorities that recognize the Convention accept the document without any further authentication by a Belgian embassy or consulate in the United States. Membership can change over time, so while Belgium remains a member as of 2026, confirm the current status on the HCCH status table before you rely on it.

An apostille verifies the origin of the document — the signature, the official capacity of the person who signed it, and any seal or stamp it carries. It does not certify that the contents are true, and it does not put the document into a language Belgium can read. That second job — translation — is separate, and for Belgium it is where the real complexity lives, because which language you need is decided by the region your document is going to.

The Regional-Language Question: French, Dutch, or German

Belgium has three official languages, and the country is divided into language regions that decide which one applies to your document. Documents used in Flanders (the northern region — Antwerp, Ghent, Bruges, Leuven) are handled in Dutch. Documents used in Wallonia (the southern region — Liège, Namur, Charleroi, Mons) are handled in French. The Brussels-Capital Region is officially bilingual, so a French or a Dutch translation is generally accepted there. And the German-speaking Community in the far east of Wallonia — the Eupen and Sankt Vith area of Liège province — works in German. The translation language is set by where your document will actually be used: the specific commune, court, or office — not by your own preference or by where you live in the U.S.

Because the apostille never translates anything, Belgium will commonly ask for a certified translation of your U.S. document alongside the apostille. Many communes and courts go a step further and require that the translation be produced by a sworn translator (traducteur juré / beëdigd vertaler / vereidigter Übersetzer) entered in Belgium's national register of sworn translators, and some require the translation itself to be certified or legalized. Requirements vary from one commune to the next, so confirm two things before you commission any translation: which language the receiving office needs, and whether it must be done by a sworn translator registered in Belgium.

Federal vs. State: Who Issues Your Apostille

There are two separate apostille tracks in the U.S., and mixing them up is the leading cause of a rejected Belgium file. Federal documents — an FBI Identity History Summary (background check) and records from other U.S. federal agencies — are apostilled only by the U.S. Department of State's Office of Authentications in Washington, D.C. A state office cannot apostille a federal document.

State-issued or state-notarized documents — birth and marriage certificates, notarized diplomas, single-status affidavits, powers of attorney — are apostilled by the Secretary of State (or the equivalent competent authority) in the state where the document was issued or notarized. A California birth certificate goes to California; a diploma notarized in Texas goes to Texas. Some documents also need a preliminary step first — a notarization, a county clerk certification of the notary's signature, or a state vital-records certification — before the Secretary of State will apostille them. We're experienced with both federal and state Secretary of State apostille processing and can help you identify the correct track for each item you're sending to Belgium.

Common U.S. Documents Belgium Asks For

The most frequent federal request is the FBI background check, usually for a long-stay (type D) visa, a residence permit, or a work permit or professional card. Belgium's Immigration Office — the Office des Étrangers / Dienst Vreemdelingenzaken — commonly expects a police clearance, and because the FBI Identity History Summary is a federal record, it is apostilled by the U.S. Department of State, never by a Secretary of State. Some offices want the check to be recent, so confirm the acceptable date range before you order it.

On the state side, birth and marriage certificates come up constantly — for registering with a commune, family reunification, and residence files — and you should always use a certified copy from the state or county vital-records office, never a hospital keepsake certificate or a plain photocopy. Diplomas and transcripts are apostilled for work permits and for recognition of a foreign diploma (equivalence is handled through the relevant Community — for example NARIC-Vlaanderen in Flanders, or the French Community's equivalence service for Wallonia and Brussels), and they usually need to be notarized or issued as a registrar-certified copy before the Secretary of State can apostille them. Single-status affidavits, covered next, round out the list.

Marrying in Belgium: The Single-Status + Birth-Certificate Combo

By far the most common reason a U.S. citizen apostilles documents for Belgium is to marry at a Belgian commune (maison communale / gemeentehuis). Communes typically ask you to prove you are free to marry and to provide a birth certificate. The proof-of-single-status document — a single-status or no-record-of-marriage affidavit — is notarized and then apostilled by the notarizing state's Secretary of State, while the birth certificate is a certified state copy apostilled by that same state. Each apostilled document is then translated into the commune's regional language: Dutch for a wedding in Flanders, French in Wallonia, French or Dutch in Brussels.

The commune is the decision-maker here, not a Belgian embassy, and communes set their own list of required documents — sometimes including how recently a birth certificate or single-status affidavit must have been issued, and often a notice or declaration-of-marriage appointment before the ceremony. Before you order anything, ask the specific commune where you'll marry for its exact list, its acceptable document age, and the translation it expects. Getting that list first saves you from apostilling and translating a document the commune won't accept.

Order of Steps and Common Mistakes

Sequence is everything. Obtain the certified record or get the affidavit properly notarized, complete any required county or state pre-certification, apostille the document, and only then have it translated by a sworn or certified translator. Reversing these steps forces a redo — translating before you apostille can leave the apostille certifying the wrong thing (the translator's notarization rather than the underlying U.S. record), or create a mismatch the commune rejects. Apostille the original first, translate second.

The Belgium-specific mistakes cluster around language and routing: translating into the wrong regional language (a French translation for a commune that works in Dutch, or the reverse), using a U.S. translator when the commune requires a sworn translator registered in Belgium, sending an FBI background check to a Secretary of State when only the U.S. Department of State can apostille it, and trying to apostille a hospital keepsake birth certificate instead of a certified vital-records copy. Before you file, confirm four things: the region and its language, the type of translator required, the issuing authority for each document, and the recency the receiving office expects.

Frequently asked questions

How long does an apostille for Belgium take?+

It depends on the document and the authority. Federal documents like an FBI background check are apostilled by the U.S. Department of State, while state documents go to the issuing state's Secretary of State — and each office has its own processing times that fluctuate with backlogs. For Belgium you also need to allow time for the certified or sworn translation and for international shipping. As of 2026 these timelines vary, so build in runway before your filing or wedding date and confirm current processing times before you order.

How much does an apostille for Belgium cost?+

It depends on the document, the issuing authority, and how fast you need it. You get a flat, all-in quote before any work begins — with no hidden fees, and no obligation.

Which authority issues the apostille for a document going to Belgium?+

It depends on who issued the document. Federal records — an FBI Identity History Summary and other federal-agency documents — are apostilled only by the U.S. Department of State in Washington, D.C. State-issued or state-notarized documents — birth and marriage certificates, notarized diplomas, single-status affidavits, powers of attorney — are apostilled by the Secretary of State (or equivalent authority) of the state that issued or notarized them. Belgium then accepts the apostille without any further embassy or consular legalization.

Do I need a certified French, Dutch, or German translation for Belgium?+

Usually yes, and the language is set by region. Documents used in Flanders are translated into Dutch, documents used in Wallonia into French, documents in bilingual Brussels into French or Dutch, and documents in the eastern German-speaking Community into German. The apostille itself never translates your document. Many Belgian communes and courts also require the translation to be done by a sworn translator registered with a Belgian court, so confirm both the language and the translator type with the receiving office before you order a translation.

What's the most common mistake people make with Belgium apostilles?+

Getting the translation wrong. The two biggest errors are translating into the wrong regional language — a French translation for a commune that operates in Dutch, or the reverse — and using a regular U.S. translator when the commune requires a sworn translator registered in Belgium. Two more to avoid: translating a document before it's apostilled (do it in the opposite order), and sending an FBI background check to a Secretary of State when only the U.S. Department of State can apostille a federal record. Confirm the region's language, the translator type, and the issuing authority before you file.
