Co-ownership Service Charges in Belgium: How They Work and What to Expect

Every co-owner in Belgium is legally obligated to contribute to the costs of maintaining and managing the common parts of the building. These contributions — commonly called service charges or charges de copropriété — are the financial lifeblood of the association of co-owners (ACP). Understanding how they work is essential for anyone owning property in a Belgian co-ownership.

Two Types of Contributions

Belgian law distinguishes between two mandatory financial contributions:

Working capital (fonds de roulement): covers recurring, day-to-day expenses such as cleaning, lift maintenance, electricity for hallways and parking, gardening, insurance premiums, and syndic fees. These are typically collected quarterly in advance, based on the annual budget approved by the general assembly.
Reserve fund (fonds de réserve): earmarked for extraordinary works such as roof replacement, facade renovation, or lift modernisation. Art. 577-11 §3 Belgian Civil Code requires a minimum annual contribution of 5% of the ordinary budget. See our detailed guide on the reserve fund.

Both contributions require a GA-approved budget, adopted by absolute majority of present or represented shares (Art. 577-6 §6 Belgian Civil Code).

Charge Distribution: General vs Special

Not all charges are divided equally among all co-owners. Belgian law distinguishes:

General charges (charges communes générales): shared by all co-owners according to their tantièmes in the common parts. Examples: roof, facade, structural walls, insurance.
Special charges (charges communes spéciales): shared only by co-owners who benefit from a specific common element. The classic example is the lift: ground-floor owners with no access to upper floors may be exempt from lift maintenance costs if the co-ownership regulations provide for it.

The charge distribution keys must be defined in the co-ownership regulations (Art. 577-4 Belgian Civil Code).

Practical Calculation Example

Consider a building with an annual ordinary budget of €60,000 and a lot holding 80/1000 shares:

| Charge type | Annual building total | Lot share (80‰) | Quarterly payment | |---|---|---|---| | Working capital | €60,000 | €4,800 | €1,200 | | Reserve fund (5%) | €3,000 | €240 | €60 | | Total | €63,000 | €5,040 | €1,260 |

Special charges (e.g., lift at €8,000/year shared among floors 1-6 only, total 700‰) would be calculated separately on a different distribution key.

Payment Terms and Late Payment

Payment deadlines are set in the co-ownership regulations or by GA resolution, typically 30 days from the date of the call for funds. Late payment triggers:

Legal interest: automatically applicable at the statutory rate (approximately 5.25% in 2025-2026).
Penalty clauses: many co-ownership regulations include a fixed penalty (e.g., 10-15% of the overdue amount), enforceable if they are not manifestly disproportionate under Art. 5.88 Belgian Civil Code.

The syndic has a duty to pursue arrears diligently. Failure to do so can constitute professional fault.

Recovery Procedure for Unpaid Charges

When a co-owner fails to pay, the standard recovery path is:

Formal notice (mise en demeure): a registered letter demanding payment within a reasonable period (typically 15 days). This is a prerequisite for court action.
Justice of the peace (Art. 577-12 Belgian Civil Code): the ACP can summon the defaulting owner before the justice of the peace, who has exclusive jurisdiction over co-ownership disputes regardless of the amount in dispute. Proceedings typically take 3-6 months.
Forced execution: a court judgment can be enforced through wage garnishment, bank account seizure, or ultimately seizure and sale of the lot.

An important rule: under Art. 577-14 Belgian Civil Code, outstanding charges follow the lot upon sale. The notary handling the sale must request a statement of accounts from the syndic. Any unpaid charges are deducted from the sale proceeds before the seller receives payment. This mechanism protects the ACP but also means buyers should verify the charge status of any lot they intend to purchase.
