Since all proceedings are customised, it is not possible to provide a detailed cost estimate in advance. The total costs of arbitration comprise the following elements:

  • Arbitrator fee: a variable amount based on the length of, financial interest in and complexity of the case, fixed at an hourly rate. This hourly rate is agreed by the Netherlands Arbitration Institute and the arbitrator upon confirmation of his appointment, pursuant to the guidelines set by the Executive Board. This hourly rate cannot be negotiated and neither can it be negotiated between arbitrators and the parties. As a rule of thumb, having three arbitrators settle a dispute will roughly involve twice the costs of having one arbitrator do so. The applicable hourly rates for arbitrators in arbitrations commenced before 1 April 2019, can be found here.
  • Other costs that must be incurred according to the arbitrator(s), such as costs of witnesses.
  • The costs of the arbitrator(s), which include the costs of a hearing room and the deposition of an arbitral award, and sometimes travel expenses, the costs of a secretary, an expert and/or an interpreter.
  • For the fees and disbursements of the arbitrators a deposit is required.

  • The NAI’s administration costs: a fixed sum calculated on the basis of a scale from EUR 500 (interest of less than EUR 25,000) to a maximum of EUR 50,000 (interest of more than EUR 250,000,000).
  • Costs of legal assistance: this could be possible. However, NAI arbitration does not oblige legal assistance.
