Since all arbitration proceedings are unique a fully detailed cost estimate cannot be provided. The total costs of arbitration are comprised of the following elements:

  • Arbitrator(s) costs:
    • Fees: a variable amount based on the length, financial interest, and complexity of the case, resulting in a fixed hourly rate. This hourly rate is agreed upon by the Netherlands Arbitration Institute and the arbitrator(s) upon confirmation of his/her/their appointment, pursuant to the rates set by the Executive Board. The hourly rates set by the Executive Board are non-negotiable.
    • The costs of the arbitrator(s), which may include the costs of a hearing room, the costs of filing an arbitral award with the courts, travel expenses, and the costs of a secretary, an expert and/or an interpreter.
    • Other costs that must be incurred according to the arbitrator(s), such as costs made to hear witnesses.
    • In order to cover the fees and disbursements of the arbitrator(s) a deposit is required.
  • The NAI’s administration costs: the amount due is calculated on the basis of the financial interest of the claim or counterclaim. Please refer to the cost calculator below to calculate the specific amount due.
  • Costs of legal assistance: NAI arbitration does not have mandatory legal representation. The arbitral tribunal may order the unsuccessful party to pay a reasonable amount for the the costs of legal assisstance of the successful party.
