On 25 May 2011 Croatia and Slovenia submitted their arbitration agreement to the UN, a necessary step before the arbitration process could begin. The treaty specifies that the arbitration process will happen after UN registration and Croatia's signing of its accession into the European Union. "It has been decided that an ad-hoc arbitral tribunal will be used to resolve the outstanding disputes. It is now believed that with the submission of the agreement to the UN that the arbitration tribunal could begin within a year, but is expected to take at least three years to reach a decision that will be binding upon each country."
