A landmark court ruling could change the future of the British aristocracy and, ultimately, the royal family.
Last week, a High Court ruling determined that the younger son of Ceawlin Thynn, the 8th Marquess of Bath, and his wife, Emma, Marchioness of Bath, can one day inherit part of his father's fortune, despite being born by surrogate.
Lord and Lady Bath, 51 and 40, respectively, share two sons, John, 11, and Henry, 9. During her pregnancy with John, the Marchioness developed hypophysitis — a rare inflammatory condition affecting the pituitary gland that can lead to serious hormonal complications and, in severe cases, become life-threatening. So, when the couple decided to expand their family, they welcomed their second son, Henry, via an American surrogate carrying their biological child.
However, because Henry is believed to be the first known member of the British aristocracy born via surrogate, questions were raised about his status under longstanding inheritance rules. Traditionally, succession rights were determined using an older legal definition of a “legitimate” child — language embedded in historic family trusts and laws that were last substantially in the 1970s, before major advances in fertility treatment and surrogacy.
In his ruling, Justice Matthews stated that it would be "unfair" to treat Henry as though he were not his father's son, according to The Daily Mail.
"Henry is the son of Lord and Lady Bath. Not only is he treated by them and will be treated by the world in general as a child of Lord and Lady Bath's marriage, but he is also their genetic child," the justice added.
Though Henry is still young, Justice Matthews said the family took on the court case now to avoid problems with U.S. taxes and ensure the possibility that Lord Bath's son can become his beneficiary in the future.

"A decision can then be taken at a later stage, in the light of appropriate advice, whether to exercise the power to add him," he added.
This isn't the first time Lord and Lady Bath have made aristocratic history. In 2020, Emma, previously Viscountess Weymouth, became Britain's first Black marchioness when her husband inherited the title upon the death of his father.
The daughter of a Nigerian oil tycoon and a British mother, Emma has found fame on reality television, mostly recently joining Bravo's Ladies of London: The New Reign, which premiered in March. She also made her Met Gala debut earlier this month, stepping out alongside celebrity pal Serena Williams.

The Baths' court ruling marks one of the first significant shifts in precedent to British succession in more than a decade. The decision is now being viewed as a potentially significant moment for Britain’s hereditary system more broadly, with legal observers noting it could eventually shape how aristocratic succession — and even royal inheritance rules — are interpreted in a modern era of assisted reproduction.
The last major decision that shifted the fates of the royal family in such a way came in 2013 when Parliament passed the Succession to the Crown Act 2013, meaning that birth order now determines who will become the next king or queen of the U.K., regardless of sex.
Previously, the British monarchy had operated under male-preference primogeniture, meaning that female siblings fell behind their male siblings in the line of succession, regardless of birth order. It affects all royals born after Oct. 28, 2011, and also removed the disqualification placed on those arising from marriage to a Roman Catholic.
In 2013, Princess Charlotte became the first female member of the British royal family to hold her place in the line of succession even after her little brother, Prince Louis, was born.
