Wedding contract in Belgium: community, separation, choosing consciously
Article summary
Legal community, separation of property, or universal community: we decode the three Belgian matrimonial regimes, the role of the notary, and what changes in the event of divorce or death.
Summarise with AI
You've been planning your wedding for months. The wedding venue, the caterer, the wedding dress, the guest list. Then a relative asks the awkward question: "Are you two getting a wedding contract?" Silence. Nobody had really thought about it.
It's normal. A wedding contract is hardly romantic, and most Belgian couples we see never sign one. This isn't a mistake in itself. But it is a choice, even when you think you're not making one. Because in Belgium, the absence of a contract automatically places you under a specific regime, with precise rules on who owns what.
Here, we explain the three Belgian matrimonial regimes, what they concretely change in the event of a divorce or death, how much a visit to the notary costs, and at what point in the planning process you need to deal with it. No unnecessary jargon. Just what you need to make an informed decision.
This article provides a framework, not personalised legal advice. Every financial situation is different, and we are neither notaries nor lawyers. To decide what's best for your case, an appointment with a notary is essential. Good news: this initial informational appointment is often free.
Getting married without a contract is already a choice
Many couples think a wedding contract is only for the wealthy or distrustful. False. In Belgian law, a wedding contract is simply the tool that allows you to choose and adapt your matrimonial regime. If you don't sign anything, the law decides for you.
Specifically: no contract, and you are married under the legal community of property regime. This regime suits many people, and that's precisely why it's the default regime. But knowing it helps avoid unpleasant surprises. The day one of you starts an independent business, buys property, or receives a significant inheritance, the rules of the regime come into play without asking for your opinion.
Marriage remains primarily a civil act declared at the local council. If you're still dealing with administrative procedures, we've detailed all of this in our guide on the documents required for a civil wedding. The wedding contract, however, is a separate layer, dealt with by a notary and not at the local council.
Wedding contract Belgium: the three regimes explained
Belgian law recognises three main matrimonial regimes. The reform that came into force on 1st September 2018 (law of 22nd July 2018, codified in Book 2.3 of the Civil Code) maintained all three, reinforcing the protection of spouses. When talking about a wedding contract in Belgium, it almost always refers to one of these three frameworks.
The three regimes at a glance
The logic is simple. The more you want to mix your estates, the more you lean towards universal community of property. The more you want to keep them distinct, the more you lean towards separation. The legal regime is the middle ground, and that explains its success. Let's look at each one more closely.
Community of property, what you share without knowing it
CHÂTEAU FERME D’ARCHE
The legal regime is based on three distinct estates, as reminded by the Belgian notariat federation. There are your own assets, your spouse's assets, and a common estate built during the wedding.
Your own assets are what you owned before you got married: an apartment bought alone, savings already built up, or what you receive during the wedding by inheritance or donation. That remains yours. The common estate, however, brings together what you acquire together after the wedding, but also, and this is where people are often surprised, your professional income. Your salaries become common. The savings built up from these salaries also.
A striking example: you buy a house three years after the wedding, with your salary savings, and the deed is in your name alone. Under the legal regime, this property is still common, because it was financed by common income. Many couples are unaware of this. This is not a flaw in the system; it is its logic: marriage creates economic solidarity. If you're planning this kind of purchase, our article on the wedding budget in Belgium can also help you get a clear picture of your couple's finances. Some also prefer to have their guests contribute via a digital wedding gift list rather than dipping into common savings.
Separation of assets, for whom and its blind spots
Separation of assets is the opposite of community of property. There is no common patrimony. Each person retains ownership and management of their assets, income, and debts. You remain in control of what is yours, full stop.
This regime primarily appeals to self-employed individuals and entrepreneurs, and honestly, it's often the right instinct when one of you is starting a business. The reason is protective: if the company encounters difficulties, professional creditors cannot claim the spouse's income. The separation of assets acts as a firewall. This is the number one argument in favour of this regime.
But it has a blind spot that I think is important to mention. The spouse who earns less, or who puts their career on hold to raise children, does not build any common patrimony. After twenty years, they may find themselves with very little in their name, while the other has accumulated capital. The 2018 reform precisely allowed for corrective clauses to be added to the separation of assets, such as a clause for participation in acquisitions. If you lean towards this regime, explicitly ask your notary how to protect the lower-earning spouse.
Buying a property together under separation of assets is still possible: it will then be held in joint ownership, in equal shares unless otherwise stated in the deed. Separation does not prevent you from investing together, it just changes who owns what by default.
Universal community of property, merging everything
This is the rarest and most radical regime. Everything is common: your income, but also assets owned before the wedding, donations, inheritances. No more separate patrimony. A single, shared mass.
Who chooses this? Often older couples, sometimes in second marriages without children from a previous union, who want maximum protection for the surviving spouse. Combined with a survivor's attribution clause, universal community of property allows the surviving spouse to recover all assets without going through traditional inheritance division. It's powerful. It also needs to be handled with caution when there are children, because it can conflict with their reserved portion of the inheritance. Again, the notary is your safeguard.
What the regime really changes: divorce, death, inheritance
As long as everything is going well, the matrimonial regime lies dormant in a drawer. It awakens at two moments: divorce and death. And there, the difference between regimes becomes very concrete.
In the event of a divorce under legal community of property, the common patrimony is divided in half. Everything accumulated during the wedding, including savings from salaries, is divided. Under separation of assets, there is nothing to share under the regime: each person leaves with what is in their name. You understand why the choice of regime carries a lot of weight if things go wrong.
Upon death, the mechanism is twofold, as explained by Belgian notaries. The matrimonial regime is liquidated first, then the inheritance is opened. The regime therefore determines the exact content of what will be transmitted. Under community of property, the inheritance covers half of the common patrimony plus the deceased's own assets. Under separation of assets, it covers their own assets and their share of any joint ownerships. These are real, quantifiable consequences, not legal theory. And they also affect how you finance and manage your couple's money on a daily basis.
The notary, the timing, and the real cost
The wedding contract is a solemn act: only a notary can draw it up. The appointment first serves to understand your situation, then to choose the regime and, if necessary, to customise it with clauses. The notary has a duty to advise, and they must inform you of the price before signing.
Regarding fees, based on the estimates observed among Belgian notaries, a standard contract costs around 350 to 500 euros, and increases beyond that as soon as custom clauses are added (participation in acquisitions, attribution to the survivor, etc.). Notary fees are partially regulated, so do not expect huge differences from one notary to another. Still, ask for a quote: it's your right.
When to take care of it
- Before the wedding: a contract signed before the big day comes into effect as soon as the wedding takes place and costs less than a later modification.
- On the day of the wedding: your regime applies, contract or not. No grey areas.
- After the wedding: changing the regime remains possible at any time, but it is a new notarised process, more expensive.
The winning reflex is to see a notary during the preparation, not in a last-minute panic. We've placed this appointment in the right spot in our month-by-month wedding planning timeline, so it's not forgotten between the dress fitting and the caterer tasting.

The first mistake is to believe that you 'don't have a regime' because you haven't signed a contract. You do have one: the legal regime. Not choosing is choosing that one.
The second mistake is basing your choice on what your friends did. The right regime depends on your situation, not on trends. A couple of employees without business plans does not have the same needs as a duo where one partner is self-employed. The third, more subtle, mistake is to sign a separation of property without a protection clause for the spouse who earns less. This can be fixed, but it's better to think about it straight away.
The last thing we see too often: postponing the notary appointment until it's too late to sign before the wedding. You lose the cost advantage and complicate your life. Whether you're planning a big party or an intimate wedding with thirty guests, the property question arises in the same way. The notary first, everything else after. And to build the team around you on that day, WEWED's directory of Belgian suppliers is there for you.

Frequently asked questions about wedding contracts in Belgium
Is a wedding contract mandatory in Belgium?
No, it is not mandatory. Without a contract, you are automatically subject to the legal community property regime. The contract is only used to choose another regime (separation, universal community) or to adapt the legal regime with tailored clauses.
How much does a wedding contract cost with a Belgian notary?
Based on observed estimates, expect to pay around 350 to 500 euros for a standard contract, more with specific clauses. Notary fees are partially regulated, and the notary must inform you of the exact price before signing.
Which regime applies if I don't draw up a wedding contract?
The legal community property regime applies by default. It distinguishes between your own assets, your spouse's assets, and joint property, which notably includes professional income earned during the wedding.
Can you change your matrimonial regime after getting married?
Yes, at any time. Simply make an appointment with a notary to amend your regime. This is a new notarised procedure, generally more expensive than a contract signed before the wedding.
Does the separation of property protect against professional debts?
Yes, that is its main advantage. In a separation of property regime, the professional creditors of one spouse cannot seize the income of the other. That's why it is often recommended when one of the spouses is self-employed or an entrepreneur.
When should the wedding contract be signed?
Before the wedding, ideally during the preparation. A contract signed beforehand comes into effect upon the wedding and costs less than a later amendment. On the wedding day, your regime applies anyway, with or without a contract.
