The unsuccessful party will bear the costs of the proceedings (both its own and the successful party’s). The parties may make agreements they consider appropriate in respect of these costs. Where no agreement is made, the court will, as a rule, apply the rates to assess lawyers' fees ranging from € 1,000 to € 12,000 for each act of process. See Annex III to the NCC Rules.

Absent special arrangements, it is noteworthy that as a practical matter, in complex litigation, each party may typically have to bear most of its own costs regardless of the outcome, given the modest amounts stated in these rates.

Throughout the proceedings, other costs generally are borne by the party incurring them. For example, a witness’s expenses are reimbursed by the party producing the witness. A court reporter’s fees are paid directly to the court reporter by the party or parties instructing the court reporter. The court will fix an amount that must be deposited in advance to cover an expert's fees and expenses and the court will order one or more parties to pay the deposit.

In the final judgment, the court will rule on which party will bear the above fees and expenses.
