Family law deals with the most sensitive moments in our lives: an impending divorce, arranging child custody, negotiating alimony. These situations blend complex legal issues with intense emotions. In Belgium, the family court - a unified jurisdiction established in 2014 - now centralizes all family disputes to spare citizens from navigating multiple courts. But this procedural simplification doesn't make the subject any less technical: between the Civil Code, private international law rules for mixed couples, and constantly evolving case law, mastering Belgian family law requires up-to-date expertise. A specialized lawyer guides you through this journey, defending your interests while preserving family dialogue when possible.

Why hire a family law specialist?

Family law isn't just about applying rules - it requires understanding family dynamics, anticipating the other party's reactions, and sometimes defusing conflicts before they escalate.

A general practitioner knows the broad outlines of divorce or filiation. But a specialist has handled hundreds of cases similar to yours. They know that the family court judge in Brussels doesn't have exactly the same practices as the one in Liege. They understand real processing times, arguments that carry weight, and pitfalls to avoid.

Above all, family law specialists have developed essential cross-cutting skills: mediation, negotiation, sometimes even training in child psychology. Because in these cases, winning at all costs can prove a Pyrrhic victory if it permanently destroys family relationships.

Finally, certain situations require specialized expertise that only a specialist can provide: international child abduction, liquidation of complex matrimonial property regimes with assets abroad, contested filiation proceedings with DNA analysis. In these cases, experience makes all the difference.

How much does a family lawyer cost?

Fees vary considerably depending on case complexity and procedure duration.

For a mutual consent divorce where everything is already settled between spouses, expect a flat fee of 1,500 to 3,000 euros per lawyer (each party must have their own, or you can choose a single lawyer if you agree on everything). The procedure is relatively quick: expect 2 to 4 months.

For a contested divorce, costs increase significantly. The hourly rate of an experienced family lawyer ranges from 125 to 200 euros in the provinces, more in Brussels or at large firms. A divorce with disagreements over child custody and property division can easily reach 5,000 to 15,000 euros, or more if the case drags on.

The good news: legal aid exists for low-income individuals. A single person earning less than 1,526 euros net per month qualifies for a free pro deo lawyer. Between 1,526 and 1,817 euros, a reduced contribution is requested. These thresholds increase by 20% per dependent.

Common family law cases

Divorce remains the most frequent dispute. Belgium distinguishes two paths: mutual consent divorce, when spouses agree on everything (children, assets, alimony), and divorce for irretrievable breakdown, when conflict persists. The latter can be granted after one year of separation, or immediately if one spouse proves the breakdown.

Child custody generates the most intense battles. The Belgian principle is equal shared custody - one week with dad, one week with mom - unless the child's best interests require a different arrangement. Judges examine each situation: geographical distance between parents, children's ages, each parent's availability.

Child support - called contribution alimentaire - is calculated based on each parent's respective income and the child's needs. Since 2010, the Renard method often serves as a reference for objectifying this calculation.

Less well-known, filiation law intervenes to establish or contest a family relationship. Paternity searches, contesting the husband's paternity, adoption: these are all procedures where the lawyer guides clients through strict deadlines and precise conditions.

Questions fréquentes

How long does a divorce procedure take in Belgium?
A mutual consent divorce can be granted in 2 to 4 months if the spouses have settled all issues. A divorce for irretrievable breakdown generally takes 6 to 18 months, sometimes longer if disagreements persist over child custody or property division. The family court always attempts conciliation before beginning adversarial proceedings.
Can I get sole custody of my children?
Sole custody (primary residence with one parent) is only granted when the child's best interests justify it: significant geographical distance, very unequal parental availability, or problematic behaviour from one parent. The judge generally favours equal shared custody to maintain the bond with both parents.
How is child support calculated?
Child support considers each parent's income, the time spent with each parent, and the child's ordinary and extraordinary expenses. The Renard method, often used as a reference, offers an objective calculation based on these parameters. The judge remains free to deviate from it depending on circumstances.
Can my ex-spouse claim alimony from me after the divorce?
Yes, if you were married and they find themselves in a state of need. This spousal support is separate from child support. It is limited in time (in principle, no longer than the duration of the marriage) and can be refused if the claimant committed a serious fault making continuation of the marriage impossible.
What can I do if my ex-spouse doesn't pay child support?
Several remedies exist. You can request a delegation of funds: the court orders your ex's employer or bank to pay you the support directly. You can also contact SECAL (Service for Maintenance Claims), which recovers arrears and can provide advances. As a last resort, a bailiff can proceed with seizure.
How can I modify a custody or support judgment?
You must file a modification request before the family court citing a change in circumstances: relocation, change in income, evolution of the child's needs. The judge then re-examines the situation and may adjust the measures. A lawyer can help you build a solid case.
Is family mediation mandatory in Belgium?
No, but it is strongly encouraged. The judge can propose mediation at any point in the proceedings, and parties can always voluntarily pursue it. An accredited family mediator helps parents reach agreements on custody, support, and property division, often more quickly and at lower cost than court proceedings.
What is the family court?
Established in 2014, the family court centralizes all family disputes: divorce, filiation, parental authority, alimony, inheritance among close relatives. A single judge follows your case over time, ensuring greater consistency in decisions. It sits in each judicial district.
