As the Duke of Sussex gears up to celebrate his 40th birthday, he’s in for a financial surprise thanks to a generous arrangement made by his great-grandmother, the Queen Mother.

Unlike his brother, the Prince of Wales, who will be honored with a traditional bell concert at Westminster Abbey, the Duke is poised to receive a significant payout from a family inheritance.

According to reports from The Times, the late Queen Mother’s substantial £70 million estate comes with a stipulation: the Duke of Sussex can access his share when he turns 40.

This arrangement puts him in a unique position, as he stands to gain more than his brother due to a skewed distribution of the inheritance.

While the Prince of Wales benefits from the wealth of the Duchy of Cornwall—a private estate that supports various public and charitable endeavors—the Duke’s payout is set to be a bit heftier.

Sources indicate that he may receive just over half of the £14 million earmarked for both brothers, which amounts to around £7 million.

In addition to this windfall, the Duke and Duchess of Sussex have been busy building their brand through various ventures, including their Netflix documentary series and the Duchess’s podcast.

Together, they are estimated to have a net worth of approximately $60 million, showcasing their ability to thrive outside royal duties.

It’s interesting to note that since stepping back from their roles as senior royals, the Duke and Duchess have seen a shift in how they are celebrated.

Gone are the customary bell ceremonies and congratulatory messages on royal social media platforms that typically accompany such milestones.

Security measures at Buckingham Palace have also tightened, meaning only a select few royal family members—namely the King, Queen Camilla, the Prince of Wales, and Princess Catherine—are now afforded the honor of these public celebrations.
