Belgian Law Explained: Codes, Regions, Courts and Key Rules (2026)

Belgian law asks a reader two questions before it will answer anything. Which language is your source in, and which level of government owns the rule?

Both questions have practical consequences, and neither has an American or British equivalent. Belgium publishes its law in Dutch and French (and, for part of it, German), and the two versions are equally authentic. It also splits legislative power between a federal state, three Regions and three Communities, so that two households a tram ride apart can face genuinely different inheritance tax, genuinely different duties on buying a house, and genuinely different rules about their rental deposit.

The good news is that the split is not random. Once you know which side of the line a topic sits on, the answer is usually clean.

Codes, not case law

Belgium belongs to the civil-law tradition. Parliament writes codes intended to cover a whole field, and a dispute is settled by identifying the applicable article and working out what it means.

That does not make court decisions unimportant. The Hof van Cassatie or Cour de cassation, the country's supreme court, shapes practice heavily, and some of the most useful rules for an ordinary reader exist only in its case law. What differs from a common-law system is the mechanism: a Belgian court is interpreting a written provision rather than extending a line of precedent that stands on its own.

The practical benefit is that you can usually read the actual rule yourself, in the actual words, for free. The Belgisch Staatsblad, called the Moniteur belge in French, publishes every statute, and its Justel database holds consolidated versions with amendments already worked in. When Belgian pages on this site cite a source, that is almost always where it points.

One warning about consolidated texts. They show the law as it stands today, which means a text can silently change under an article number you cited last year. This matters enormously in 2026 because of the Penal Code, discussed at the end of this page.

The codes you will meet most often

Belgium is midway through replacing its 1804 civil code, so which code applies depends on the topic. This is the single most common way a source about Belgian law goes out of date.

The new Burgerlijk Wetboek, or Code civil, has arrived in pieces:

• Book 3 (property, neighbour nuisance, co-ownership) took effect on 1 September 2021.
• Book 2, Title 3 (relatievermogensrecht, the law of marital property) took effect on 1 July 2022.
• Book 4 (inheritance, wills and gifts) took effect on 1 July 2022.
• Book 6 (buitencontractuele aansprakelijkheid, non-contractual liability) took effect on 1 January 2025.

Book 6 is the one most likely to catch a source out, because it replaced the article every Belgian civil claim used to start from. For decades the answer to "someone harmed me, what do I sue under" was article 1382 of the old code. Articles 1382 to 1386bis are now repealed, and the fault-liability rule lives at article 6.5, with fault itself defined at article 6.6. The changeover is governed by when the harmful act happened, not when you file: facts from 1 January 2025 onward fall under Book 6, and anything earlier is still judged under old article 1382. Any source still framing a present-day civil claim around 1382 alone is working from the pre-2025 law.

The old Burgerlijk Wetboek of 1804 still governs persons and family in the narrow sense. Divorce grounds, parentage, custody, child support and spousal maintenance have not been recodified, and no bill covering those titles has reached Parliament. Note the exception, because it is easy to get backwards: marital property law has moved to the new code, so a question about your matrimonial property regime is a new-code question while a question about your divorce is an old-code one.

The Strafwetboek, or Code penal, is the criminal code and holds the offences this site follows most closely, including unlawful recording of a private conversation and the defamation offences. It is the code being replaced on 1 September 2026.

Employment sits outside the civil code entirely, in the wet van 3 juli 1978 betreffende de arbeidsovereenkomsten, the loi du 3 juillet 1978 relative aux contrats de travail. Notice periods were rewritten by the unified-status reform of 26 December 2013 and again twice in 2026.

Procedure runs through the Gerechtelijk Wetboek or Code judiciaire, and road rules through the Wegverkeerswet and the traffic code.

Federal law, regional law, and the line between them

Belgium has a federal state, three Regions and three Communities. The two layers are not the same map, and confusing them is the standard newcomer mistake.

The Regions are territorial: the Vlaams Gewest (Flanders), the Waals Gewest (Wallonia) and the Brussels Hoofdstedelijk Gewest (Brussels-Capital). They handle territory-linked matters, and they are the layer that matters for the topics on this page.

The Communities are language-linked rather than territorial: the Flemish, the French and the German-speaking Community, the last covering roughly 79,500 people around Eupen in the east. Communities run education, youth protection, and much of health and family policy. Brussels has no single Community government of its own; instead three bodies exercise Community competences there, the VGC for the Flemish Community, COCOF for the French Community, and the bi-communal GGC, known in French as COCOM.

For employment, inheritance, tenancy and criminal law, the Communities are not the relevant layer, which is why the rest of this page speaks only of Regions. But if your question involves a minor in trouble with the law, a school dispute, or youth-protection services, you are dealing with a Community.

The following are federal and uniform across the country:

• Employment contracts, notice periods, dismissal and severance
• Divorce, child support, spousal maintenance and parentage
• The civil rules of inheritance: who inherits, what share is reserved, how wills work
• Criminal law, including recording, privacy and defamation offences
• Criminal records and the extracts issued from them
• Traffic offences, fines and licence withdrawal
• Neighbour nuisance and co-ownership

The following are regional, and this is where a national answer is simply wrong:

• Inheritance and gift tax. Flanders, Wallonia and Brussels each set their own brackets, rates, exemptions and reliefs, and they differ substantially. The Flemish administration is VLABEL; Wallonia and Brussels have their own.
• Registration duties on buying a home. These differ by Region in both size and shape. Flanders charges 2 percent on a sole owner-occupied home against a standard 12 percent. Wallonia charges 3 percent on a habitation propre et unique against a standard 12.5 percent. Brussels does not discount the rate at all, staying at 12.5 percent, but exempts the first 200,000 euro of the price where the total does not exceed 600,000 euro, which is worth up to 25,000 euro. Read that difference carefully: two Regions give you a lower percentage, and the third gives you a smaller taxable base.
• Residential tenancy. Regionalised by the Sixth State Reform in 2014, with each Region legislating separately from 2018 onward. Deposit caps and notice rules genuinely differ.

There is one common trap worth naming. People say "employment is regional in Belgium." That confuses two different things. Labour law, meaning your contract, your notice period and your dismissal rights, is federal. Labour market policy, meaning job placement through VDAB in Flanders, Forem in Wallonia and Actiris in Brussels, has been regional since the Third State Reform of 1988 and 1989, with the Sixth State Reform of 2014 adding a further package on top covering activation of jobseekers, availability checks, service vouchers and target-group measures. Your notice period does not change when you cross a regional border. Your job centre does.

A fourth layer: your municipality

Below the Regions sits a layer that catches newcomers out because it has real teeth. Individual municipalities can sanction breaches of their own local ordinances through gemeentelijke administratieve sancties, the sanctions administratives communales, universally shortened to GAS or SAC. These cover noise, litter, public-order nuisances and some parking, and they are imposed by a municipal sanctioning official rather than a judge. The maximum is 500 euro for an adult and 175 euro for a minor. An adult contests a GAS fine before the politierechtbank; a minor's case goes to the jeugdrechtbank instead.

Which region applies to you

For inheritance and gift tax, the competent region is decided by the fiscal domicile of the deceased or the donor, specifically wherever they lived longest during the five years before death or before the gift. It is not decided by where the heirs live, and not by where the property sits. Someone who dies in a Flemish hospital after decades in Namur is taxed by Wallonia.

For tenancy and for registration duties, the rule is simpler: what governs is where the property is located.

The layer above the employment statute

Reading only the federal employment statute gives a misleading picture of what a Belgian worker is actually entitled to, because a second layer sits on top of it.

Belgian employment is organised into sectors, each with a paritair comite or commission paritaire, a joint body of employer and union representatives. These committees conclude collective agreements, the CAO or CCT, covering minimum pay scales, year-end bonuses, extra leave, supplementary notice arrangements and much else. When such an agreement is made generally binding by Royal Decree, the mechanism known as algemeen verbindend verklaring, it binds every employer falling within that committee's scope, whether or not they belong to an employers' federation and whether or not their staff are union members.

The practical consequence is that two workers with identical seniority, in the same city, doing similar jobs, can have materially different entitlements purely because they sit in different sectors. Your committee number is the key to which agreements apply to you, and it customarily appears on your payslip, though the federal minimum-content rules for payslips do not themselves require it and the requirement varies by committee.

Language, and why it is a legal question

Belgium has three official languages: Dutch, French and German. Statutes are published in Dutch and French, and both versions are authentic, meaning neither is a translation of the other in law. Some instruments also appear in German for the German-speaking Community.

For a reader this has three consequences.

First, the same institution has two names, and neither is more correct. The small-claims court is the vredegerecht and the justice de paix, and the judge sitting in it is the vrederechter or juge de paix. The labour court is the arbeidsrechtbank and the tribunal du travail. This site names both, because a reader searching in Dutch and a reader searching in French are looking for different words for the same thing.

Second, official websites are language-mirrored. If justitie.belgium.be does not load a page, justice.belgium.be usually has the same content, and the reverse is also true.

Third, the language of your proceedings is set by rules, not by preference. Outside Brussels it generally follows the language of the region where the court sits. In Brussels the position is more specific than "you can choose": under the law of 15 June 1935, the language is determined in the first place by the defendant's domicile, and the plaintiff gets a genuine choice between Dutch and French only where the defendant lives in the Brussels agglomeration or has no known Belgian address. Separately, a defendant can ask at their first appearance for the case to switch to the other language.

The courts you might actually end up in

Belgian courts are organised by subject far more than by the amount in dispute.

The vredegerecht, or justice de paix, is the most accessible court and the one an ordinary person is most likely to see. It handles smaller civil claims and, importantly, has dedicated jurisdiction over tenancy disputes and neighbour disputes regardless of the sum involved.

The arbeidsrechtbank, or tribunal du travail, hears employment and social security disputes, including dismissal and severance claims.

The familierechtbank, or tribunal de la famille, sits inside the court of first instance and handles almost all family matters, including divorce, custody and maintenance.

The jeugdrechtbank, or tribunal de la jeunesse, also sits within the court of first instance and deals both with minors in danger and with offences committed by minors. It applies Community youth-protection decrees rather than the ordinary Penal Code, which is the clearest everyday example of the Community layer having real legal effect.

The politierechtbank, or tribunal de police, handles traffic offences and the civil claims that follow road accidents, and hears appeals against municipal administrative fines.

The correctionele rechtbank, or tribunal correctionnel, is the criminal section of the court of first instance and handles the middle tier of offences, which under the current code includes most defamation prosecutions.

Above these sit the hof van beroep or cour d'appel, then the Hof van Cassatie or Cour de cassation, which reviews only the legality of a decision and is not a third instance on the facts. Separately, the Grondwettelijk Hof or Cour constitutionnelle rules on whether a statute, decree or ordinance respects the division of powers and the fundamental rights in Title II of the Constitution.

One cost rule that surprises Americans

Belgium does not follow the American rule under which each side pays its own lawyer whatever the outcome. The losing party generally owes the winner a statutory contribution toward legal costs, the rechtsplegingsvergoeding or indemnite de procedure, under article 1022 of the Gerechtelijk Wetboek. It is a capped, scale-based amount set by Royal Decree according to the value of the claim, not the winner's actual bill, so it neither reimburses a winner fully nor exposes a loser without limit. It does mean that losing a case in Belgium costs more than losing the argument, which is worth building into any decision about whether to litigate.

The legal professions, and who does what

Belgium has no single profession matching the American attorney. The work is divided.

An advocaat, or avocat, advises and represents clients in court. Pleading before the courts is essentially reserved to them under article 440 of the Gerechtelijk Wetboek, with narrow exceptions. They are organised in two bar federations, the Orde van Vlaamse Balies and AVOCATS.BE.

A notaris, or notaire, is a public officer who handles successions, wills, gifts, property transfers and the property settlement in a divorce by consent. For most inheritance questions the notary, not the lawyer, is the professional you will deal with.

A gerechtsdeurwaarder, or huissier de justice, serves documents and enforces judgments.

One useful thing to know: there is no general monopoly on legal advice in Belgium. What is reserved is representation before the courts. Banks, insurers, municipal social services and various associations legitimately give first-line legal information, which is why free front-line advice is comparatively easy to find.

What is changing in 2026

Belgium is in an unusually busy year, and several of these changes are recent enough that most sources have not caught up.

A new Penal Code takes effect on 1 September 2026. Published in April 2024 and originally due in April 2026, its start was pushed back in March 2026 after concerns from the judiciary. It is a genuine replacement rather than an amendment. It abolishes the old three-way classification of offences into misdaad, wanbedrijf and overtreding and replaces it with eight penalty levels. It renumbers the offences: unlawful recording of a private conversation moves from article 314bis to article 342, and the defamation and insult offences move out of the old chapter at articles 443 to 452. Most strikingly, the lightest level carries no prison option at all, and defamation sits at that level, so imprisonment disappears as a penalty for it.

Criminal fines went up on 1 February 2026. Fine amounts written into the current Penal Code are historical figures that must be multiplied by a separately-set factor, the opdecimes. That factor moved from 70 to 90 decimes, meaning the figure in the article is now multiplied by ten rather than eight. Any source quoting the bare article figure, or applying the old multiplier, understates the real fine badly. The new Penal Code removes this quirk and states real amounts directly.

Notice periods changed twice. Contracts starting on or after 1 June 2026 have their employer notice capped at 52 weeks once the employee reaches 17 years of service. A second reform, for contracts starting from 1 August 2026, replaces the graduated notice steps inside the first six months with a flat one week.

Brussels closed the gift look-back gap on 1 January 2026. An unregistered gift is pulled back into the taxable estate if the donor dies within a set period. Wallonia moved to five years in 2022 and Flanders in 2025; Brussels was the last at three years and joined them this January.

Flanders raised an inheritance-tax exemption on 1 January 2026, taking the exempt tranche of movable assets from 50,000 to 75,000 euro. Note the limit on this one: it applies to what a surviving spouse or partner inherits, and does not extend to children or other heirs.

Where Belgian law is already covered on this site
