The will of Queen Elizabeth II, if the public could see it, would provide rare insights into the late monarch's wealth.
But unlike those of ordinary British citizens, hers will be sealed and locked in a safe for at least 90 years.
The practice of sealing the wills of deceased royals dates back to 1910 and the seldom remembered Prince Francis of Teck, whose will is one of more than 30 kept in a safe in an undisclosed location in London, under the care of a judge.
