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 (pdf, 129.9 KB).
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.
