According to previous events and protocols in the British monarchy, Kate Middleton would suffer a significant title reduction when his oldest son, Prince George, became King, the most important position for any person in the royal family.
In recent days, a new question has arisen about the future of the monarchy: “Will Princess Catherine curtsy Prince George when he becomes king?” It is now known that the rules of the royalty indicate that everyone in the room is obliged to greet the King with a bow.
Although these rules only apply in official settings and private matters can be different, it is highly likely that Kate will follow the example of her predecessors, The Queen Mother, who followed all protocols when her daughter Queen Elizabeth ascends to the throne at the age of 25.
Regarding this, Kate Middleton, after being the Queen of the United Kingdom, would have to bow to Prince George when he succeeded his father, Prince William, as head of state, which would significantly reduce her title in the royal family.
