In practice, that clause means the dispute belongs in arbitration, not court: if you sue in the Dubai courts and the client invokes the clause, the court will normally decline to hear the case. Arbitration in the UAE is governed by the Federal Arbitration Law, and the award the tribunal eventually issues is binding and enforceable through the courts. The process starts when you file a request for arbitration with the institution named in the clause — often the Dubai International Arbitration Centre — and pay the filing fee; a tribunal is appointed, and both sides exchange written submissions and evidence before a hearing. Whether it is worth it for a medium-sized claim comes down to cost against recovery: institutional and tribunal fees are real money, though arbitration is often faster than litigation, and a formal request for arbitration alone frequently brings a silent debtor to the negotiating table. Before committing, check that the clause actually covers this dispute and is validly drafted, and remember interim measures may still be available. An arbitration practitioner can read the clause and give you a realistic cost-benefit view before you start the clock.
