State court or arbitration?
The central choice is between a state court and arbitration, for example under the DIS or ICC Rules. State court proceedings are often less expensive, but may continue through several levels of appeal and take longer. Hearings are generally public, and the ease of enforcing a judgment abroad depends on the country concerned and the applicable treaties.
Arbitration normally costs more because the parties also pay the arbitrators and, where relevant, the institution. In return, there is usually only one instance, the proceedings can remain confidential and the process can be adapted more closely to the parties' needs. Its most important advantage is often the international enforceability of the award. The better option therefore depends on the value and nature of the dispute, the commercial relationship, the likely enforcement states and the need for confidentiality.
