High Court summons sets up rare public questioning of Andrew Mountbatten-Windsor
Andrew Mountbatten-Windsor has been served with a witness summons compelling him to give evidence in a High Court fraud trial expected to begin in mid-November, with his appearance anticipated around 15 December. The case centers on allegations by Nebahat Isbilen, an elderly Turkish woman who says her former financial adviser, Selman Turk, misled her and used her wealth for his own advantage. Mountbatten-Windsor is not accused of wrongdoing, yet the summons places his financial arrangements directly into the frame and is likely to draw intense public attention when he appears in court.
His evidence will be taken in person unless the court permits video appearance. For Mountbatten-Windsor, it would mark the first public questioning he has faced since the BBC Newsnight interview in 2019. It is also believed to be the first witness summons served on a royal since the 19th century, a procedural detail that gives the case an unusual constitutional and media dimension even though the underlying dispute is a private financial one.
Disputed transfers sit at the center of the evidence
Court documents place two transactions under scrutiny. One involves a transfer of £750,000 that Isbilen claims she made after being misled by Turk into believing the money would help with a passport. Turk has denied that account and says the payment was a gift made on Isbilen’s own initiative to create goodwill with the then Duke of York, with no connection to a passport. The second disputed sum is around £768,000 paid from Isbilen’s account in January 2020.
Those transfers matter because they sit close to the end of Mountbatten-Windsor’s time as a working royal and because the chronology raises questions about who knew what, and when. The £750,000 transfer came the day after he recorded his Newsnight interview, which was broadcast the following evening, before he stepped back from royal duties. In 2021, Isbilen’s lawyers contacted him and the money had already been repaid, but the broader litigation continues to examine the conduct of Turk and the handling of Isbilen’s assets.
The trial is not about a single payment in isolation. It is about the mechanics of influence, consent, and financial control, especially where a vulnerable account holder says decisions were made without full understanding.
Turk’s account and the disputed Swiss chalet claim
Turk has strongly denied dishonesty. His representatives say he looks forward to being vindicated in court. One of the disputed claims concerns the January 2020 payment of roughly £768,000. Turk has said the money was a loan to Mountbatten-Windsor for the purchase of a chalet in Switzerland, an assertion contested by Isbilen and challenged in previous hearings.
The legal significance of Mountbatten-Windsor’s testimony is straightforward: if the court accepts that he has relevant knowledge about how the funds were presented, discussed, or transferred, his answers may help establish the chain of events surrounding the transactions. If his evidence conflicts with either party’s account, it could sharpen the factual dispute rather than resolve it. In financial fraud cases, contemporaneous explanations often matter as much as the final paper trail.
The relationship between the parties developed through Pitch@Palace, the Dragon’s Den-style pitching project run by Mountbatten-Windsor. Turk met him in autumn 2019 through that initiative, and the connection later extended into social gatherings involving Turk and his family, Isbilen, and the then Duke and Duchess of York. Those social links are not peripheral. They may help explain why money moved through channels that the plaintiff says she did not fully understand.
Judicial permission and the reach of a witness summons
Justice Adam Johnson ruled that, given the seriousness of the allegations, Turk should have access to “the evidence he considers relevant and material.” On that basis, Mountbatten-Windsor was summoned as a witness. The court’s decision does not assign blame to him, but it does recognize that his evidence may bear directly on questions the tribunal must decide.
A witness summons of this kind is uncommon, and for a former senior royal it adds a layer of visibility that ordinary fraud litigation does not usually carry. Still, the procedural point is plain: a witness can be compelled to attend if the court considers the testimony relevant. In this case, the summons turns a private financial dispute into a public hearing with implications for credibility, financial transparency, and the handling of disputed wealth.
The hearing is expected to begin later this month, and Mountbatten-Windsor has been approached for a response. When he appears, the court is likely to probe the financial arrangements behind the disputed payments, his understanding of the transactions, and whether any of the money said to have reached him was presented as a gift, a loan, or something else entirely. Those distinctions sit at the heart of the case.
What the court will be testing when the evidence starts
The trial will not revolve around Mountbatten-Windsor as a defendant. It will revolve around whether Turk misled Isbilen and used her wealth for personal benefit, and whether the disputed payments were handled in a lawful and honest way. Yet Mountbatten-Windsor’s appearance could shape how the court interprets the wider story. His first public comments since being stripped of his titles may also become one of the trial’s defining moments, even if he is there only as a witness.
The case also exposes how quickly personal introductions can become financial entanglements. A social connection formed through a royal pitching project evolved into allegations involving very large sums of money, conflicting accounts of intent, and questions about who benefited from the transfers. The High Court will now hear those accounts under oath, with documentary evidence and witness testimony tested in open court.
For Isbilen, the litigation seeks answers about how her money was used. For Turk, it is a fight to defeat allegations of dishonesty. For Mountbatten-Windsor, the summons means being drawn into a trial that may ask difficult questions about payments said to have reached him, even though he is not accused of any crime. The hearing will begin with those questions unresolved.
