2024 NAI Arbitration Rules

With effect from 1 March 2024,  new arbitration rules are in force: the NAI Arbitration Rules 2024 (Arbitration Rules). These new Arbitration Rules provide for even more efficient and faster dispute resolution through innovative tools. A newly developed arbitration platform facilitates secure electronic communication. There is also a focus on sustainability, diversity and inclusivity in the new Arbitration Rules.

For 75 years, the NAI has been a leading arbitration institute in Europe that stands for quality and innovation. We are constantly working to optimise our processes and further develop our services. The new Arbitration Rules are a good example of this. The changes in the new Arbitration Rules are extensive.
