Jordanian royal Princess Haya, 45, a wife of 70-year-old United Arab Emirates Prime Minister Sheikh Mohammed bin Rashid Al-Maktoum, has applied for the order, a non-molestation order and for wardship of their children, the High Court heard.
The clash between Sheikh Mohammed and Princess Haya is the latest sign of trouble in Dubai's ruling family.
Last year, a daughter of Sheikh Mohammed tried to flee Dubai after appearing in a 40-minute video saying she had been imprisoned.
