Divorce in Belgium: who keeps the house?
The Immolytics editorial team
A divorce in Belgium turns on three decisions: who keeps the family home, how the other person's share is paid for, and at what value. The procedure matters, but the property weighs more than anything else in the split. This guide follows the order that works, from the matrimonial regime to the valuation.
Your matrimonial property regime decides ownership, not the procedure
In Belgium, the matrimonial property regime determines who owns what: a court ends the marriage, it does not redistribute assets. A couple married without a contract falls under the legal regime, where property acquired during the marriage is in principle shared, while assets received by gift or inheritance stay with the spouse who received them. A marriage contract or a separation of property regime changes the picture completely, so read the deed before you negotiate anything.
For unmarried couples, ownership follows the purchase deed and what each person contributed: proof of payment counts more than stated intentions. Legal cohabitants benefit from protection of the family home, but the division of assets still follows what was bought and paid for. In both cases the split happens after the marriage or the cohabitation ends, and a divorce by mutual consent lets you record one overall agreement, property included, in a single document.
The notary is the key figure at this stage: the notary drafts the deed of sale or of buyout, checks each person's rights and organises the payments. See one early, before you start arguing about amounts.
Four ways out for the family home
In practice there are four exits: sell the property and split the proceeds, buy out the other person's share, stay in joint ownership, or transfer the property to a child. The choice depends on each person's borrowing capacity, the value of the property and how much the two of you agree.
- Sell and share the proceeds: the simplest route when neither person can take over the financing. The price obtained fixes everything else, which is why you value the property before signing.
- Buy out the other share against a cash payment: you keep the home, the other person receives their share in money. The buyout calculation takes the property value, the outstanding mortgage and the costs already paid into account.
- Stay in joint ownership: possible, but heavy to carry. Shared building charges keep running and a later resale becomes harder to organise.
- Transfer the property to a child: a gift of property can settle the split, but inheritance tax and the regional rules need checking before anything is signed.
When disagreement blocks everything, a judicial division of assets can end in a public sale, which puts the property back on the market. Another route for an owner who wants capital without moving out: selling en viager in Belgium.
Cash buyout and mortgage: check the financing before you promise
The buyout is the sum paid to the other person to even out the shares, and the bank decides whether it can be financed. It looks at income, outgoings, the running mortgage and the value of the property after the operation, never at intentions.
Three points decide. First, the joint mortgage must be repaid or taken over: the person keeping the property often has to refinance, by increasing the loan or by granting a new mortgage. Second, a co-borrower stays liable to the bank until the bank has agreed in writing to release them: that release is the only clean exit. Third, the bank recalculates the loan-to-value ratio and the weight of the monthly payment on a single income, which can sink a buyout that looked obvious on paper.
The guide to mortgage credit in Belgium sets out the products, the costs and how borrowing capacity is calculated. No rate is promised here: credit advertising is regulated by the FSMA, and a site that is not a licensed intermediary sticks to information. Before you choose between keeping and selling, a buy versus rent simulation helps you work out what the property really costs over time.
EPC and renovation rules depend on the Region
Energy obligations are not federal: they vary by Region, and a divorce does not suspend them. A property that is sold or rented stays subject to the rules of its own territory.
- In Flanders, a sale triggers a renovation obligation. It is the only one of the three regions where this applies.
- In Brussels, performance targets are set per dwelling, with their own dates and no link to a sale.
- In Wallonia, an EPC certificate is compulsory for the sale and the letting of a dwelling, with no renovation deadline.
These rules change the real value of the property, and therefore the size of the buyout. The renovation obligation in Belgium explains the Flemish case, and the EPC certificate in Belgium covers the cost and the obligations. An energy audit shows what has to be done, a renovation calculator estimates the spend, and the return on a green renovation checks whether the works come back in the sale price. EPC subsidies depend on the invoice and on regional criteria: they are checked case by case.
Value the property before you split it
The division is calculated on a documented market value, never on an asking price and never on what the property cost ten years ago. Value it too high and one person pays an excessive buyout; too low and the other's share is given away.
Benchmarks come from official data: price statistics from Statbel and figures from the notaries, compared municipality by municipality. The free estimator for a municipality gives an order of magnitude in a few minutes, and a written valuation of an apartment gives both parties a basis for discussion. To place an unusual property, comparing with the cheapest municipalities in Belgium is a useful reminder that the same budget does not buy the same thing everywhere.
One point of method: only registered sales count. A property listed at a high price is not proof of value, and an advert does not replace a comparison of actual transactions.
Frequently asked questions
Who pays the mortgage on the house during a divorce?
Each borrower stays liable to the bank until the bank has agreed in writing to release them. A judge can organise who occupies the family home, but that does not replace the bank's agreement on the loan.
Can we sell the house before the divorce is finalised?
Yes, in principle, if all the owners agree before a notary. Without agreement, the sale goes through the division of assets, and a total deadlock can lead to a public sale.
What happens if one person wants to keep the house?
The person who keeps it pays a buyout to the other and takes over the financing, with the bank's agreement. If the buyout cannot be financed, selling remains the most likely outcome.
