The parties in arbitration expect to resolve their dispute in a high-quality, exhaustive and more efficient manner compared to the proceedings before the state courts. In order to do this, the parties expect to be able to fully present their side of the story by obtaining and presenting the evidence they deem necessary to prove their claims. However, the tribunals are private forums and do not have the powers of the state courts at their disposal such as the state coercive apparatus. This limitation is especially evident when it comes to gathering of evidence, and even more so when the evidence is placed outside the country of the seat of arbitration. In such situations, cooperation between courts and the tribunals as well as international court assistance is needed. International conventions regulate the matter of court assistance in taking of evidence in international arbitration only in outline, leaving it up to each state to elaborate further with its procedural and arbitration laws the procedure and prerequisites for submitting such a request to the courts. This paper will primarily show how the framework for assistance of courts in taking of evidence in international arbitration is organized on the international level, and how different the state approach can be.
