Getting married in Belgium

Overview of marriage laws in Belgium

Every legally valid marriage in Belgium rests on a single act: a ceremony performed by the registrar of the Civil Registry in the municipality where one future spouse lives or is registered. The Belgian Civil Code sets out the substantive conditions behind that ceremony: both spouses must be at least 18, give free consent, not already be married, and not be related in a way that Belgian law treats as a barrier to marriage, such as being siblings or direct-line relatives. Since March 11, 2023, a person bound by a Belgian legal cohabitation (a registered partnership short of marriage) cannot marry anyone other than that cohabitant.

Same-sex marriage has been legal in Belgium since June 2003, and it follows the same civil procedure as any other marriage. For a same-sex marriage to take place in Belgium, one partner must be Belgian or have been habitually resident in the country for more than three months.

A marriage performed abroad is not automatically valid in Belgium. Recognition is assessed on a case-by-case basis and hinges on two separate tests: the marriage must have respected the substantive conditions of each spouse's national law, and it must have followed the official formalities of the country where it was celebrated. Meeting one test without the other is a common reason a foreign marriage certificate is later rejected for use in Belgium.

Conditions to get married in Belgium

The declaration of marriage has to be filed in person with the registrar of the municipality where one future spouse resides or is registered, and there is no separate regional variation: every commune applies the same national conditions, though each sets its own appointment process. Once the file is lodged, the ceremony itself must take place at least 14 days and at most six months after the declaration.

That 14-day window rarely determines how quickly a foreign national can actually marry in Belgium. The real gatekeeper is the connection to the country: a tourist with no Belgian nationality, domicile, or qualifying residence cannot simply walk into a town hall and file a declaration. Foreign nationals in that position generally need a dedicated marriage visa, either a short-stay Visa C or a long-stay Visa D issued for the purpose of marrying in Belgium, and checklists for this visa type typically require a copy of the municipal declaration of marriage issued within the six months before the visa application is submitted.

There is no fixed waiting period after a divorce or a spouse's death before remarrying in Belgium. The condition is documentary rather than time-based: anyone who was previously married must produce evidence that the earlier marriage ended, and if that evidence comes from abroad and is not in Dutch, French, or German, it may need both legalization and a certified translation before a registrar will accept it.

Marriage configurations in Belgium

Two foreign nationals can marry each other in Belgium as long as one of them is domiciled there or has been habitually resident for more than three months; the declaration is filed with the registrar of that person's municipality at least 14 days before the intended date. When a foreigner marries a Belgian citizen, Belgian law governs the Belgian spouse's capacity to marry (age, marital status, absence of a conflicting legal cohabitation, consent, and family relationship), while the foreign spouse's capacity is judged under their own national law. The ceremony itself, wherever the couple's nationalities lie, is always conducted under Belgian rules. Marrying a Belgian citizen does not, on its own, grant Belgian nationality to the foreign spouse.

The extra paperwork in a mixed or fully foreign couple usually falls on whichever partner is not yet registered in a Belgian Population Register, Register of Non-nationals, or Waiting Register. That person must supply proof of nationality, evidence of not being currently married (or proof that a previous marriage ended), and proof of residence, in addition to the standard birth certificate and identity document. A registrar can refuse to record the file if any of these are missing.

A same-sex marriage certificate issued abroad follows the same recognition rule as any other foreign marriage: it must meet the substantive conditions of each spouse's national law and the formal requirements of the country of celebration, and it must be legalized or apostilled and translated into the applicable Belgian municipal language when required.

Civil vs religious marriage in Belgium

Belgium works on a fixed order that surprises expats used to different systems: some countries let a wedding at a registered religious venue serve as the legally binding ceremony itself, with no separate civil step. Belgium does not work that way. The civil ceremony before the municipal registrar is the only legally valid marriage, and it is the sole official record of the union, performed by the mayor or the alderman responsible for civil registry matters in the municipality where the declaration was filed.

A religious ceremony, whatever the faith, has no independent legal standing on its own. Couples who also want a Catholic, Orthodox, Jewish, Protestant, or Muslim ceremony (each following its own liturgy and preparation set by the religious community, not by Belgian civil law) schedule it after the town-hall marriage, never before or instead of it. No document list exists specifically for a religious ceremony because it carries no legal weight of its own; the documents that matter are the ones the civil registrar requires.

Prenuptial agreements in Belgium

Some legal systems leave marital property entirely to a court's discretion at divorce, dividing assets on fairness principles with no automatic regime in between. Belgium takes a different starting point: if spouses sign no marriage contract, the statutory community-of-acquisitions regime applies automatically. Everything acquired during the marriage becomes shared property, while whatever each spouse owned beforehand, along with certain personal assets, stays individually owned.

For couples with foreign assets, property owned before the wedding, or different expectations about what should be shared, that default regime often isn't the right fit. The alternative is a notarial marriage contract ("contrat de mariage" in French, "huwelijkscontract" in Dutch), which lets future spouses choose a different property regime. It has to be drawn up by a notary, and the couple must inform the civil registrar and submit the notary's certificate when filing the declaration of marriage. The notarial fee for drafting one ranges from about EUR 8.55 to EUR 195 (USD 9 to USD 205), excluding taxes or additional notarial work, a modest cost relative to what is at stake if the wrong regime applies for years. Disputes over a contract's validity or interpretation are recorded in the Central Register of Matrimonial Agreements and can be brought before a court.

Timing matters: a marriage contract must be signed before the wedding to govern the marriage from day one. Changing the matrimonial regime after the marriage has already started is a more formal and more expensive process. Recognition of a Belgian marriage contract outside Belgium is not automatic either, so couples with assets, succession plans, or possible divorce proceedings in another country should get legal advice in that jurisdiction alongside Belgian notarial advice.

Required documents for marriage in Belgium

The paperwork burden in a Belgian marriage file falls almost entirely on whichever spouse is not already registered in the country. Both future spouses present a national identity document or passport, and copies of both sides are required for online municipal requests. Each also provides a copy of their birth certificate, though the registrar requests this directly if a spouse was born in Belgium or the certificate is already transcribed there.

A future spouse who is not registered in Belgium's Population Register or Register of Non-nationals has to go further, with the following documents:

• Evidence of not being married, or proof of the dissolution or annulment of a previous marriage where applicable, issued by the competent authority in that person's home country
• Documentation of a former marriage's end through divorce, annulment, or the death of a previous spouse, where relevant
• A certificate of residence or a rental contract proving the more-than-three-months residence condition

The registrar decides whether these documents are adequate and can refuse to record the declaration if they are not, so it is worth confirming exactly what a specific municipality expects before requesting anything from abroad.

Any foreign-language document intended for use in Belgium must be translated into Dutch, French, or German by a sworn translator, and if the translation is done abroad, the translator's signature also needs legalization or an apostille. Whether a document itself needs an apostille or full legalization depends on the issuing country and the type of document: Belgium's electronic apostille system applies where the issuing country's convention membership makes apostille the correct route, while other documents go through standard legalization, where the competent authority checks signatures, stamps, or seals. Applicants can use the FPS Foreign Affairs legalization tool to confirm the exact route for a document's country of origin.

There is no universal validity period for foreign birth certificates or proof-of-single-status documents; municipal registrars decide on a case-by-case basis. The only nationally fixed window is procedural: the 14-day minimum before the wedding and the six-month ceiling after the declaration, so flag any document that might expire before the ceremony date early, rather than assuming it will still be accepted.

Role of embassies and consulates in Belgium

Belgian federal authorities and a foreign national's own consulate cover two different halves of the paperwork, and it helps to keep that division straight from the outset. Proof of single status, or an equivalent certificate, is country-dependent: it comes from the applicant's home-country embassy or consulate, not from any Belgian authority, and its format and availability vary by nationality. The practical move is to contact the Belgian municipality first about exactly what it needs, then the home-country consulate second about what it can actually issue, rather than assuming either side offers a standard package.

On the Belgian side, the eLegalization service can legalize or apostille Belgian civil-status certificates recorded in the national civil status database, covering most Belgian birth and marriage certificates needed for use abroad. Belgian apostilles are issued electronically, though whether a given foreign document needs an apostille or full legalization to be usable in Belgium still depends on the issuing country and the document type.

After the wedding, a foreign spouse should also ask their own country's consulate whether the new Belgian marriage certificate needs to be transcribed or registered in their national civil records, since a Belgian municipal certificate only proves civil status within Belgium itself. For legal questions that go beyond routine paperwork, such as a disputed prior marriage, a complex filiation issue, or a nationality question tied to the marriage, the Association pour le droit des étrangers (ADDE) runs an in-person legal permanence covering international family law for foreign nationals, on a first-come basis with limited capacity.

Good to know:

A bilateral agreement between Belgium and the United Kingdom waives the standard legalization requirement for certain official documents exchanged between the two countries, which can simplify producing a UK-issued document for a Belgian marriage file, or using a Belgian marriage certificate for a UK registration.

Planning timeline for marriage in Belgium

Belgium's own statutory minimum, the 14-day declaration period, is rarely what determines how quickly a foreign national can marry there. The real pace is set by how long it takes to obtain a foreign civil-status document, get it apostilled or legalized in the issuing country, and then have it sworn-translated into a Belgian national language. Starting three to six months before the intended wedding date is a realistic baseline once you factor all of that in.

A workable sequence looks like this: confirm with the Belgian municipality exactly which documents it requires, obtain recent civil-status documents from the issuing country, arrange apostille or legalization there, get certified translations into Dutch, French, or German, and only then file the declaration with the Belgian registrar. For documents already issued in Belgium, apostille or legalization is processed immediately at the counter in Brussels for files up to four pages, or within five working days when submitted through a notary; lead times for apostilles on foreign-issued documents depend entirely on the issuing country and are not standardized.

The most common causes of delay are missing documents, papers that still need legalization or an apostille, and foreign-language documents that still need a certified translation, any one of which lets the registrar refuse to record the declaration. Building the schedule around the slowest foreign document rather than Belgium's 14-day minimum, and avoiding documents that might expire before the appointment, are the two adjustments that save the most time.

Marriage procedures in Belgium

The Belgian marriage process runs as a fixed, linear sequence, and the couple's only real decisions are which municipality is competent and whether to pay for an upgraded ceremony slot.

1. File the declaration of marriage with the civil registrar of the municipality where one future spouse lives or is registered in the Population Register, Register of Non-nationals, or Waiting Register, at least 14 days before the intended date.
2. Prepare the required documents before filing: copies of birth certificates, proof of identity, and a notary's certificate if a marriage contract has been signed. A spouse not registered in Belgium must also provide proof of nationality, proof of single status, and proof of residence.
3. The registrar reviews the file and decides whether the documents submitted are adequate, and can refuse to record the declaration if required papers are missing.
4. If the registrar refuses the declaration, the couple can appeal to the Court of First Instance within one month of being notified of the refusal.
5. The civil ceremony takes place between 14 days and six months after the declaration, in the municipality where it was filed, before the mayor or the alderman responsible for civil registry matters. Witnesses are optional; couples may choose up to four, and any witnesses attend the ceremony and sign the marriage act.
6. The marriage is recorded directly in the Belgian civil status registers. Certified copies or extracts can then be requested, viewed, and downloaded through Just-on-web, subject to local taxes that vary by municipality.

Some municipalities also offer a premium ceremony option inside the town hall for an additional fee. In Brussels, the "Courtyard tariff" lets couples choose a Friday or Saturday slot and the City Hall's Cour d'Honneur entrance, at an added cost on top of the standard civil ceremony fee.

Costs and fees for marriage in Belgium

The legal marriage itself is inexpensive in Belgium. A basic civil ceremony at Brussels City Hall costs EUR 50 (USD 53), and choosing the premium Friday or Saturday slot at the Cour d'Honneur brings the total to EUR 300 (USD 316), the base tariff plus a EUR 250 supplement. Issuing the marriage certificate itself is free of charge at the City of Brussels; separate fees only apply for legalization, apostille, or a multilingual format needed abroad.

The cost that actually adds up for foreign nationals is document legalization, priced at EUR 25 per document (USD 26) as of August 1, 2026. That fee multiplies quickly across a birth certificate, a proof-of-single-status document, and any prior divorce or death certificate that needs converting for Belgian use. A realistic total for the legal process alone, excluding any wedding event and the cost of obtaining documents abroad, runs from about EUR 50 to EUR 350 (USD 53 to USD 369): the ceremony fee, an optional premium supplement, and legalization charges for whichever documents need them.

Good to know:

Belgian consular posts abroad also charge their own fees for related paperwork, such as USD 30 to certify a document or legalize a signature. That charge is separate from whatever fee your own country's authorities apply to issue the proof-of-single-status document or marriage affidavit you need for the Belgian file.

Wedding traditions and customs in Belgium

Belgian wedding celebrations typically split into two separate events built around the legally decisive appointment. Close family often attends the civil ceremony at the town hall, followed by photographs, a drinks reception, a seated meal, speeches, dessert, and an evening party with dancing. Couples who want something more personal than the brief legal appointment sometimes add a separate secular or symbolic ceremony lasting about 30 to 45 minutes, in addition to the required civil step.

Gift customs mix tradition with newer habits: alongside a store gift list, many couples now offer a shared online "money pot", often put toward a honeymoon or a home project, or a mix of selected physical gifts. Dress expectations follow the formality of the event: simple or dressed-up for the civil ceremony depending on the couple, smarter for the full reception unless the invitation sets a specific theme.

Because the civil ceremony is the event that counts and must be filed at least 14 days in advance, it is worth confirming the commune's acceptance of the file and locking in the ceremony date before booking non-refundable reception venues or vendors around it.

After the wedding in Belgium

The marriage certificate is drawn up electronically right after the spouses exchange consent and is registered automatically in the national civil status database (BAEC/DABS), free of charge. For certificates already in that database, the City of Brussels issues copies or extracts immediately online or at the counter; email requests take about five working days, older certificates transcribed before 2004 take about ten working days, and foreign certificates add one to five working days for legalization. Couples can request either an extract or a full copy through the MyBXL portal, by email, or in person, and should specify if the document is needed abroad so any legalization, apostille, or multilingual format can be added at that stage.

A multilingual international extract of the marriage certificate is accepted without further legalization by countries party to the 1976 Vienna Convention on multilingual civil-status extracts, but it's worth checking the destination country's status before relying on it. Whether the marriage also needs to be registered in a spouse's home country depends entirely on that country's own law, not on any Belgian rule, so confirming this directly with the relevant embassy or civil registry avoids surprises later.

A marriage concluded abroad can also be recorded into Belgian civil status: the City of Brussels first reviews a scan of the documents, then requires the originals along with any needed translations and legalizations, and once approved, enters the marriage into BAEC and updates civil status to "married."

Marriage supports a family-reunification visa application for a spouse or minor children, but it does not by itself grant Belgian residence. Processing windows for spouse or family-reunification long-stay visas range from about three weeks to six months, depending on the sponsor's category and whether Immigration Office approval is required. Beyond immigration status, a few administrative loose ends are worth handling directly: the Belgian civil-status update proves the marriage exists, but it does not automatically change private insurance contracts or beneficiary designations, so those need updating separately.

Divorce in Belgium

Belgium offers two divorce routes. Divorce by mutual consent lets spouses who agree on the divorce and its consequences generally avoid a court appearance entirely. Divorce for irretrievable breakdown can be filed jointly after six months of separation, or unilaterally after one year, and applies whenever full agreement is not reached.

Belgium recognizes foreign divorces on a case-by-case basis, mainly refusing recognition where it would conflict with Belgian public policy, where a party's right to a defense was violated, where the decision is still appealable, or where it conflicts with a Belgian or earlier foreign ruling on the same matter. Property division follows whatever matrimonial regime the couple set, whether through a marriage contract or the statutory default, which is why the decision made before the wedding still matters at the end of it. Custody decisions follow the child's best interest, and Belgium is party to the Hague Convention on child abduction for cross-border custody disputes.
