The Disney Monarch Kingdom?

The King Charles Clause, also known as the Royal Lives Clause, is a legal provision that originated in the British monarchy in the 17th century. It was created to ensure that the property would remain within a family’s control for as long as possible, even in the event of the death of the last survivor of the descendants.

In essence, Disney’s agreement restricting the newly appointed Reedy Creek board’s powers will be in effect until 21 years after the death of the last survivor of King Charles III.
