Royals Prince Philip's Will to Remain Secret for at Least 90 Years to Protect 'Dignity' of Queen Elizabeth Prince Philip died at the age of 99 on April 9 By Gabrielle Chung Published on September 16, 2021 11:48 PM Share Tweet Pin Email Prince Philip. Photo: Matt Dunham/Getty Prince Philip's will is to remain secret for at least 90 years to protect the "dignity" of Queen Elizabeth II and other members of the royal family, a London judge has ruled. Sir Andrew McFarlane, the president of the Family Division of the High Court, made the order on Thursday, according to multiple outlets. McFarlane, who has not seen or been told of the will's contents other than the date of its execution and the identity of its appointed executor, ruled that a private process can be held after the 90-year period to determine if the documents should be unsealed, the BBC reports. "I have held that, because of the constitutional position of the Sovereign, it is appropriate to have a special practice in relation to royal wills," McFarlane said in a written judgment, per the outlet. "There is a need to enhance the protection afforded to truly private aspects of the lives of this limited group of individuals in order to maintain the dignity of the Sovereign and close members of her family."

"I accepted the submission that, whilst there may be public curiosity as to the private arrangements that a member of the Royal Family may choose to make in their will, there is no true public interest in the public knowing this wholly private information," he said, according to the BBC.
