Prestel & Partner's German-edition Family Office Forum runs 22–23 September 2026 at the Sofitel Frankfurt Opera in central Frankfurt am Main. The organizer describes the edition as its 81st forum worldwide and states that 2026 moves from the Nassauer Hof in Wiesbaden to Frankfurt while that property is renovated, keeping the Wiesbaden branding for returning guests. Its register page defines a true family office for this edition as a single family office with AUM of at least EUR 150 million serving one family or individual, not a multi-client solutions provider, and states that single and selected multi-family-office delegates register free while provider passes are sold at GBP 4,490 for both days or GBP 2,990 for one day, plus 19% German VAT. The organizer publishes an agenda built around investment strategy, private markets and long-term value creation alongside governance, succession, next-generation leadership, health and longevity, and says provider passes are capped so that families remain the majority of the room. Prestel & Partner Ltd is the London-based organizer of the international Family Office Forum series. No attendee or delegate roster for the 2026 Frankfurt edition is published.
