Divorce in Belgium means closing one chapter while opening a new one. It is important to understand how the divorce procedure works, what documents you need, and the relevant timelines, so you can save time, money, and emotional strain.
This guide provides you with up-to-date information on how you can proceed with a divorce in Belgium, the legal requirements, the deadlines involved, and the key issues that may influence the final outcome, such as child custody arrangements or the division of assets.
Divorce procedure
In Belgium, the divorce process can follow two main paths, depending on the couple’s situation:
- Divorce by mutual agreement, when both spouses agree to end the marriage.
- Divorce on the grounds of irretrievable breakdown, when the relationship has definitively collapsed, even if one spouse does not consent to the separation.
Both procedures are handled by the Family Court in the area where the spouses (or one of them) reside, but they differ in terms of duration, steps involved, and requirements. Below, we explain each option in detail.
💡 Useful tip: Belgium is one of the European countries where divorce can be finalized more quickly if there is full agreement between the spouses.
If you’ve already decided to separate amicably, we recommend reading our dedicated article on divorce by mutual agreement in Belgium.
Divorce by mutual consent
Divorce by mutual agreement is the fastest and most affordable option, as both spouses separate on a consensual basis. To proceed with this type of divorce, the couple must first have agreed on all key aspects of their separation, including:
- The division of movable and immovable property, as well as bank accounts
- The family home and related expenses
- Child custody arrangements and child support
- Spousal maintenance, if applicable
- The allocation of debts and shared costs
All of this must be set out in a divorce agreement, which will be reviewed by the Family Court to ensure it complies with the law and protects the best interests of any children involved. Once the agreement is approved, the judge issues the divorce order, which is then recorded in the civil registry. The entire process usually takes between two and six months, depending on the court’s workload and how quickly the necessary documents are submitted.
🕊️ Advantage: A mutual agreement divorce in Belgium allows the parties to retain control over the decision-making process, while keeping costs lower than in a contested procedure.
Divorce due to irretrievable breakdown
A divorce based on irretrievable breakdown applies when one or both spouses believe they can no longer remain married. Unlike mutual agreement, in this case the will of just one spouse is enough to request the dissolution of the marriage. For the judge to acknowledge that the marriage has broken down irretrievably, certain conditions must be met:
- A de facto separation of at least 6 months, or 12 months if only one spouse files for divorce
- Evidence demonstrating that living together or reconciling is no longer possible, such as police reports, emails, messages, witness statements, medical reports, and so on
The family judge will hear both spouses and assess all the evidence before issuing a decision. The judge will also rule on child custody, child support, and the use of the family home if the spouses cannot reach an agreement.
Example: A couple who has been living apart for more than a year, with minimal communication and no shared household, can generally demonstrate an irretrievable breakdown without difficulty.
💡 Professional tip: Although this type of divorce can be initiated unilaterally, strong evidence and a clear presentation of the facts are essential.
On average, a divorce based on irretrievable breakdown in Belgium can take between six months and one year, depending on the complexity of the case and whether there are children or shared assets to divide.
Differences between the two types of divorce
| Aspect | Mutual Agreement | Irretrievable Breakdown |
|---|---|---|
| Initiative | Both spouses | One or both spouses |
| Level of conflict | Low | Medium to high |
| Estimated duration | 2 to 6 months | 6 to 12 months |
| Need for evidence | No | Yes (period of separation or proof of breakdown) |
| Control over decisions | Full (joint agreement) | Partial (the judge decides) |
What if one of the spouses lives outside Belgium? If one spouse resides abroad, the divorce can still be processed in Belgium as long as one of them has their habitual residence in the country and meets the required minimum residence period.
Important aspects of a divorce
A divorce in Belgium involves resolving several essential issues. These elements —the division of assets, child custody, and financial support or maintenance— are the ones that most influence both the duration of the divorce proceedings and their economic and family impact.
Parental authority
In Belgium, parental authority generally remains joint after a divorce, except in exceptional circumstances. This means that both parents continue to make important decisions together regarding their children: schooling, medical care, extracurricular activities, administrative matters, and key aspects of their upbringing. Even when custody is not shared equally, parental authority does not disappear — each parent retains their rights and responsibilities toward the child. In cases of ongoing conflict or situations that could endanger the child’s well-being, the family judge may adapt how parental authority is exercised in order to ensure the child’s stability and protection.
Division of assets in a Belgian divorce
The division of assets is one of the most sensitive stages of any separation. In Belgium, the marital property regime chosen at the time of marriage (community of property or separation of property) determines how assets and debts are divided.
Under a community property regime, any assets acquired during the marriage (the family home, bank accounts, investments, vehicles, etc.) are considered jointly owned and must be divided fairly. Under a separation of property regime, each spouse keeps ownership of whatever they acquired individually. If the spouses cannot reach an amicable agreement, the family judge will appoint a notary to organise the sale, allocation, or distribution of the assets, taking into account each party’s contributions and the presence of any children.
💡 Professional tip: Before starting the process, it is advisable to make a full inventory of assets and debts.
Child custody and residence
When it comes to child custody, Belgian law always prioritises the best interests of the child. There are several possible custody arrangements:
- Exclusive custody: One parent is granted full custody of the children, with no visitation rights for the other (rare and exceptional).
- Primary custody: The children usually live with one parent, while the other has visitation and/or stay rights.
- Shared custody: This is adapted according to the children’s age, the parents’ work schedules, and the distance between their homes.
If the parents cannot agree, the family judge will determine the arrangement that best serves the children’s well-being, taking into account factors such as stability, the availability of each parent, proximity to school, and keeping siblings together.
Spousal maintenance
Spousal maintenance is a financial payment that one former spouse may receive if, after the divorce, they are in a situation of economic need. The judge assesses several factors to determine the amount and duration, such as the length of the marriage, each spouse’s financial and domestic contributions, the standard of living during the marriage, and the age and health of the parties. This maintenance must be expressly requested during the judicial proceedings. It may also be revised or terminated if the parties’ financial circumstances change.
💡 Useful note: In certain cases, spousal maintenance may have tax implications (partial deductibility or taxation in personal income tax).
Child support contributions
Child support is the amount one parent pays to the other to cover the children’s ordinary and extraordinary expenses: housing, food, clothing, education, medical care, and extracurricular activities. In Belgium, the calculation of this contribution depends on the net income of both parents, the number and age of the children, the amount of time the children spend with each parent, and the fixed costs related to housing and schooling.
Practical example: If both parents have similar incomes and share custody, the contribution may be low or even unnecessary. However, if one parent earns significantly more or spends less time caring for the children, the amount will be higher.
In practice, child support in Belgium is similar to what is known in Spain as pensión alimenticia, although the calculation methods and criteria may differ.

Timeframes for divorce proceedings in Belgium
The length of divorce proceedings in Belgium depends on the type of procedure chosen and the level of agreement between the spouses. Divorce by mutual consent is the fastest option, as long as both parties agree not only to the divorce itself but also to all its consequences: custody, visitation arrangements, division of property, use of the family home, child or spousal maintenance, and so on. The estimated duration ranges from 2 to 6 months, depending mainly on how quickly the divorce agreement is drafted and signed, the court’s workload, and whether there are minor children (in which case the judge will pay particular attention to the children’s best interests).
A divorce based on irretrievable breakdown generally takes longer because it requires proving that the marital relationship has definitively collapsed—whether through facts, evidence, or statements before the court. The estimated duration ranges from 6 months to 2 years, depending on whether there are disputes over child custody, asset division, payments, or other matters. In highly contentious cases, especially those involving substantial assets or major disagreements, the process can take even longer.
Practical tips for handling a divorce in Belgium
A well-organised divorce reduces stress and speeds up the entire process. These practical tips for divorcing in Belgium will help you protect your interests and make informed decisions.
Document your assets, accounts, and financial situation
It is very useful to prepare a complete inventory from the outset, listing both joint and individual assets, and to gather and keep copies of all relevant financial documents such as bank statements, property contracts, tax returns, or investment records. Being organised from the beginning makes the court’s work easier and helps minimise disputes over the ownership or value of certain assets.
Prioritise the well-being of your children
In Belgium, the best interests of the child are the primary consideration in judicial decisions. It is therefore advisable to reach agreements and stick to plans regarding school holidays, long weekends, and public holidays, in order to provide stability. Focusing on the children’s needs—and, when necessary, making use of family mediation—often helps maintain a balanced co-parenting relationship.
Consider the tax implications of the divorce
Many people are unaware that certain support payments may have tax consequences. The paying parent may be entitled to tax deductions, while the receiving parent must declare those amounts as income. In addition, dividing assets such as property, shares, or investments may result in tax obligations that need to be assessed. For this reason, it is important to consider the matrimonial property regime and the future financial obligations of each spouse.
Review your pension and social security rights
Finally, it is essential to understand how the separation will affect your pension and social security rights. In many cases, divorce can have an impact on the retirement benefits you may be entitled to, especially if one spouse was financially dependent on the other or if there were shared contributions. It is also worth checking how the separation affects access to certain benefits, ensuring that your social security registration is updated, and reviewing your long-term financial planning once the divorce is formalised.
Cross-border divorce in Belgium
Cross-border divorces arise when spouses have different nationalities, live in different countries, one or both have moved outside the EU, or when issues such as custody or asset division involve elements in more than one country. These situations require an understanding of international jurisdiction rules, as well as the recognition and enforcement of judgments across borders. This is where the Brussels II ter Regulation becomes particularly relevant.
For example, if one or both spouses live in Belgium, Belgian courts may have jurisdiction over the case. If only one spouse resides in Belgium, they must have lived there for at least six months (for Belgian nationals) or twelve months (for non-Belgians) before filing for divorce. Cross-border divorces often involve spouses of different nationalities or couples living in separate countries.
In such cases, the Brussels II ter Regulation (which replaced Brussels II bis) determines which court has jurisdiction to handle the divorce. The regulation includes criteria such as the couple’s last common residence (if one spouse still lives there), the habitual residence of the respondent, or the habitual residence of the spouse filing for divorce if they have lived there for the required minimum period. If children are involved, cross-border divorce proceedings may also cover parental responsibility and custody, with Brussels II ter providing rules to determine jurisdiction and ensure effective cooperation between courts in EU member states.
