    For which problems

    For any technical dispute during the construction or renovation of a building (roofing, humidity, isolation and ventilation, central heating, flooring, window frames, veranda, stairs…)


    Summary of the various rates, always including VAT:

    1. simple assessment: € 332.75 per party
    2. complex expertise: 
      • fee for simple expertise: € 332,75 per party
      • hourly fee from start of complex procedure: 121€/hour to be shared between all parties;
      • travelling expenses: 1,21€/km to be shared between all parties;
      • secretariat: 42,35€/hour to be shared between all parties.

    In case of co-ownership, a supplement of € 121 per co-owner who is party to the dispute will be charged, which means that in case of a dispute between an association of co-owners and a promoter regarding the common parts, a sum of €332,75 will be charged for the simple procedure. This sum will be increased by € 242 if two co-owners also file a complaint with regard to their private spaces.

    Languages of the procedure:

    • French

    • Dutch

    Prerequisites for access

    • You must have tried to solve the dispute directly with the company, to no avail
    • You must have filled in and signed the standard clause making the Commission competent in the case (available in French or in Dutch), either when you signed the contracts or when the dispute arose. 

    How does it work

    The Commission organises a hearing during which it designates, based on the file and on the parties’ declaration, the most appropriate conciliator-expert for the technical problem in question. The expert will then visit the location and try, after this visit, to reconcile the parties; if it proves impossible, he will write a technical report. This report is binding for the parties. Disputes are usually solved within a maximum of six months. In case of failure, the parties can still take the matter to a court.
