Dubai's billionaire ruler, Sheikh Mohammed bin Rashid Al Maktoum, has opened a legal case against one of his wives, Princess Haya bint al-Hussein, CNN has learned.

British media reports claim Princess Haya, who is the daughter of the late King Hussein of Jordan, has left her husband and traveled from Dubai to London. But at the moment, CNN is unable to verify either her whereabouts or those reports.

The princess is a well-known international figure, being close friends with the heir to the British throne, Prince Charles and his wife Camilla, the Duchess of Cornwall.

The case is being heard in London, at the Family Division of the High Court, and the next hearings will be on July 30 and July 31.

When contacted by CNN, the Royal Courts of Justice confirmed the court dates, but not the identity of the two parties.

"The case was last heard on the 22 May 2019 before Mr Justice Moor and the case is next listed before the President on the 30th July 2019," reads the statement from the court.

CNN has separately confirmed both the dates and the parties involved in the legal case.

Sheikh Al Maktoum will be represented by Lady Helen Ward of Stewarts, a high-profile law firm in London, CNN has also learned.

Princess Haya is the half-sister of the King of Jordan and received a British education, completing a degree in Politics, Philosophy and Economics at Oxford. She is a keen equestrian, representing Jordan at the 2000 Olympics in Sydney.
