Château Fiduciaire
Château Fiduciaire operates as a multi-family office anchored on Geneva's rue du Mont-Blanc, where it owns the building it occupies. President Patrick-Dominique Bittel and administrators Jean-Marc Wenger and Pascal Aeby steer a quiet fiduciary practice serving families and individuals with wealth structuring, preservation, and transfer. The firm became publicly visible only through litigation — as trustee for The Map Trust, a 1997 vehicle established by the late David Fine for his children, and as administrator of the Cayman-registered Forward Sports Fund that held Leeds United until Ken Bates bought the club in 2011. Investment exposure spans hedge funds, insurance-linked and re-risk strategies, and sports franchises. The Leeds United ownership structure illustrates the firm's operating model: an anonymous offshore entity layered under Swiss administration, with no public-facing brand. Beyond sports, the firm scans Web3, blockchain, and ESG technologies as thematic focuses. Château Fiduciaire applies no minimum or standardized mandate — each family's deployment is negotiated privately and structured through Luxembourg, Cayman, or Swiss corporate SPVs, with direct co-investment, fund-of-funds, and trust-administered vehicles all in play. Geographic concentration sits in Europe. The firm also directly holds Swiss commercial real estate through related companies including Société Immobilière Rue du Mont-Blanc 7 SA and an asset at 3, place du Molard. Bittel, Wenger, and Aeby serve as directors of these holding entities, keeping property and fiduciary services under the same umbrella. No philanthropic foundation, club memberships, or external investment committees are publicly disclosed. What distinguishes Château Fiduciaire structurally is its posture as a fiduciary shell rather than an investment brand. It does not market, does not publish performance, and appears designed to be invisible — the entity owning the entity. Succession and governance sit entirely with the three named administrators, whose public trail exists almost exclusively in commercial registry filings and the Leeds United litigation. For families that require a Swiss nexus with no story, that architecture is the product.

Frequently asked questions
Who runs investment decisions at Château Fiduciaire?
President Patrick-Dominique Bittel, alongside administrators Jean-Marc Wenger and Pascal Aeby, oversees client mandates from the firm's Geneva headquarters. The firm does not disclose an investment committee or external advisors. Public records show the three men have directed the firm's fiduciary and real-estate holding entities for years.
Is Château Fiduciaire a single family office or a multi-family office?
It is structured as a multi-family office, serving unnamed families and individuals with tailored fiduciary, wealth management, and advisory services. The Fine family relationship, disclosed in 2009 litigation over The Map Trust, is one of the few publicly documented client connections. The firm's client list is otherwise private.
What was Château Fiduciaire's role in the ownership of Leeds United?
The firm administered Forward Sports Fund, a Cayman Islands-registered entity that held ownership of Leeds United Football Club from 2005 until 2011. Ken Bates was the club's chairman during that period. The fund sold the club to Bates in 2011, ending the visible link between the Swiss fiduciary and the English football asset.
What investment types does Château Fiduciaire deploy into?
Confirmed exposures include hedge funds, insurance-linked and re-risk strategies, and sports and esports franchises, according to Altss research. The firm also registers thematic interest in Web3, blockchain, and ESG technologies. Specific fund commitments and direct positions are not publicly disclosed.
What is Château Fiduciaire's geographic focus?
The firm's investment and fiduciary activities concentrate on Europe. Its own real estate holdings are in Geneva, Switzerland. Offshore vehicles used for client structuring — such as Cayman Islands entities — provide non-European legal wrappers, but the underlying asset and family bases remain primarily European.
