17 Shocking Rules the British Royal Family Secretly Must Follow

The British Royal Family looks like a picture-perfect fairytale from the outside. However, behind the palace doors lies a strict network of protocols, centuries-old traditions, and downright bizarre rules. From dining etiquettes to travel restrictions, the members of the House of Windsor live a highly regulated life.

Here are 15+ shocking rules the British Royal Family secretly must follow.

1. No Monopoly Allowed Inside the Palace

It sounds like a joke, but the world’s most famous board game is strictly banned inside the royal residence. Prince Andrew once revealed that the family is not allowed to play Monopoly because it gets “too competitive” and leads to fierce family arguments.

2. Young Boys Must Only Wear Shorts

Have you ever noticed that Prince Louis is always spotted in shorts, even during freezing winters? According to royal tradition, putting young boys in full trousers is considered “middle class.” Royal boys must only wear shorts in public until they turn 8 years old.

3. Two Direct Heirs Cannot Fly Together

To protect the line of succession, two direct heirs to the throne are strictly forbidden from traveling on the same aircraft together. For example, Prince William and Prince George cannot fly on the same plane, just in case a tragic accident occurs.

4. A Black Outfit is Mandatory in Every Luggage

Whenever a royal member travels abroad, they must pack a strictly black outfit. This rule ensures that if a family member passes away while they are overseas, they can step off the plane in appropriate mourning attire.

5. No Autographs for Fans

If you ever meet King Charles or Prince William, don’t bother asking for an autograph. Royals are forbidden from signing their names on scrap pieces of paper or fans’ hands to prevent the risk of their signatures being forged or replicated.

6. No Garlicky Foods During Public Events

The late Queen Elizabeth II absolutely hated garlic, but the rule goes beyond personal preference. Royals are banned from eating garlic or overly oniony foods during official tours and public engagements to avoid having bad breath while speaking to dignitaries.

7. The King’s Flight Suitcase Includes Blood Bags

When the monarch travels, a royal navy doctor always accompanies him. The King’s luggage literally includes bags of his own blood plasma in case an emergency blood transfusion is required in a foreign country.

8. You Must Stop Eating When the King Stops

Dining with the King comes with a ticking clock. The moment King Charles finishes his last bite and places his cutlery down, everyone else at the dinner table must immediately stop eating—even if your plate is still half full.

9. No Shellfish While Traveling

To avoid the risk of severe food poisoning, allergic reactions, or stomach bugs during high-profile international tours, royal members are strongly advised to stay away from shellfish like crabs, oysters, and shrimp.

10. The “Duchess Slant” Sitting Style

Royal women, including Kate Middleton and Meghan Markle, are not permitted to cross their legs at the knee in public. Instead, they must keep their knees together, slant their legs to one side, and cross their ankles if necessary. This modest posture is famously called the “Duchess Slant.”

11. Tiaras are Strictly for Married Women

Wearing a glittering diamond tiara is a privilege reserved exclusively for married royal women. A princess cannot wear a tiara until her wedding day. It serves as a traditional sign that the woman is officially “off the market.”

12. King Charles Doesn’t Need a Passport

While the rest of the family carries diplomatic passports, King Charles III travels the world completely document-free. Since all British passports are issued in the name of the reigning Monarch, the King legally does not need one. He also doesn’t need a driving license!

13. Shell-Free Shellfish and Specific Water Packings

When King Charles travels for official tours, his staff packs his own personal Malvern water, specific organic foods, and even his own orthopedic bed and toilet seat to maintain strict health and comfort standards.

14. Shell Suits and Tracksuits Are Forbidden

While the world loves casual streetwear, you will almost never see a royal in a shell suit or oversized tracksuit during a public duty. Casual wear for them means a smart blazer and chinos for men, and a neat day dress for women.

15. The Secret Handbag Communication Code

The late Queen Elizabeth II famously used her Launer handbag to send silent signals to her staff. If she shifted her bag from her left arm to her right, it meant she was bored of a conversation and wanted her ladies-in-waiting to rescue her. If she placed it on the floor, it meant she wanted to leave the event immediately.

16. Garlic and Shellfish are Banned, but so is Foie Gras

King Charles, being a passionate environmentalist and animal rights supporter, officially banned the French delicacy “Foie Gras” from all royal palace menus due to the cruel method used to force-feed ducks and geese.

17. PDA (Public Display of Affection) is Heavily Discouraged

While there is no written law, royal couples like Prince William and Kate Middleton rarely hold hands or kiss during official royal duties. They are representing the British Crown on a professional level, so they keep their behavior strictly business-like.
