The short version
- A London High Court judge authorized a witness summons for Andrew Mountbatten-Windsor, potentially the first instance of a royal receiving such an order since 1870.
- The civil case involves allegations that a former adviser misappropriated funds and misled a Turkish client about a payment made to the former prince in 2019.
- Mountbatten-Windsor repaid the money in 2021 and is not a defendant, but he may apply to have the summons dismissed as police continue investigating his links to Jeffrey Epstein.
A significant legal precedent involving the British monarchy has emerged after Andrew Mountbatten-Windsor was formally called to testify in a civil fraud trial. The High Court in London issued the directive, marking what legal observers and media reports describe as the first time in more than 150 years that a member of the royal family has been served with a witness summons. This development underscores a shifting landscape for the institution, which has long operated outside standard judicial scrutiny.
The summons relates to a lawsuit filed by Nebahat Evyap Isbilen, a Turkish national who alleges that her former financial adviser, Selman Turk, misappropriated tens of millions of pounds from her accounts. Central to the dispute is a payment of 750,000 pounds, equivalent to approximately one million dollars, which Isbilen claims she was misled into making to Mountbatten-Windsor in 2019. She asserts that Turk convinced her the funds were necessary to secure influence or assistance for her husband.
Isbilen’s legal team contends that her husband has been imprisoned in Turkey since 2015 as a victim of political persecution, and that the payment was intended to leverage Mountbatten-Windsor’s connections to aid his release. Conversely, Turk maintains that Isbilen authorized the transaction willingly, believing it would facilitate diplomatic or personal intervention on behalf of her spouse. The court has determined that testimony from the former prince is relevant to clarifying the nature and authorization of this specific financial transfer.
Mountbatten-Windsor is not a party to the lawsuit itself. He repaid the 750,000-pound sum in 2021, a move widely reported as an effort to distance himself from the controversy surrounding the payment. Despite his non-party status, the judge granted permission for his testimony last month, indicating that his account of the transaction is considered material to the resolution of the fraud allegations against Turk. The former prince retains the right to apply to have the summons set aside, meaning his actual appearance in court is not yet guaranteed.
The historical rarity of this event highlights a distinct break from royal tradition. Legal experts note that the last comparable instance occurred in 1870, when the future King Edward VII, then Prince of Wales, was summoned to testify in a divorce case brought by Charles Mordaunt. In that earlier proceeding, the prince accepted the summons and denied allegations of improper relations with Mordaunt’s wife, Harriet. The current situation differs significantly, as it involves civil fraud rather than personal scandal, yet both cases illustrate moments when royal privilege intersected with judicial authority.
This legal development occurs against a backdrop of ongoing scrutiny regarding Mountbatten-Windsor’s associations. Several British police forces are currently investigating his links to Jeffrey Epstein, the convicted sex offender who died in 2019. These inquiries were intensified after the U.S. Department of Justice released millions of pages of documents from its investigation into Epstein earlier this year. The release of these records prompted renewed public and media interest in the former prince’s conduct and relationships.
The institutional response to these controversies has been severe. King Charles III stripped Mountbatten-Windsor of his princely title in late 2025, a decisive move aimed at shielding the wider royal family from the fallout of the Epstein-related scandals. This demotion reflected a broader strategy to limit reputational damage and signal a break from past associations. The witness summons adds another layer of legal exposure for Mountbatten-Windsor, further complicating his standing within the public sphere.
As the case proceeds, attention will focus on whether Mountbatten-Windsor challenges the summons or complies with the court’s order. His testimony could provide critical insight into the dynamics between Isbilen, Turk, and himself during the period surrounding the 2019 payment. Regardless of his participation, the mere issuance of the summons represents a notable erosion of the traditional immunity enjoyed by senior royals in civil proceedings.
The outcome of this trial may set a precedent for how future disputes involving royal figures are handled within the British legal system. While the monarchy remains protected by convention and protocol, the willingness of courts to issue such directives suggests a growing expectation of accountability. For now, the case remains active, with both sides preparing their arguments amidst heightened public interest in the intersection of wealth, influence, and justice.
Observers note that the proceedings will likely continue for months, given the complexity of international financial fraud cases. The involvement of a high-profile figure such as Mountbatten-Windsor ensures that media coverage will remain intense. Whether he testifies or not, the episode serves as a reminder that legal obligations can extend even to those who have historically operated beyond the reach of ordinary judicial processes.
