Citywealth has unveiled its Top 30 Transatlantic Select: Advisors and Managers 2026, a new ranking that identifies the lawyers, tax specialists and wealth managers serving families with assets on both sides of the Atlantic. The list was published on 22 July 2026 and maps what Citywealth describes as the US-UK advice corridor.
The ranking focuses on professionals who operate across both jurisdictions, reflecting the growing complexity families face when managing wealth that spans American and British tax, legal and regulatory regimes. Citywealth did not publish detailed selection criteria or methodology in the announcement.
The list arrives as cross-border wealth structuring has become more demanding for family offices. Families with dual exposure to US and UK tax systems face overlapping compliance obligations, inheritance tax planning challenges and coordination requirements across multiple advisory teams.
Citywealth has not disclosed whether the selection process involved nominations, peer review or quantitative metrics. The publication also did not specify whether the thirty advisors were ranked in order or presented as an unranked cohort.
The timing of the list coincides with a period of flux in UK tax policy. John Healey became the UK's sixth chancellor in just over four years on 20 July 2026, and advisers have called for an end to constant speculation on inheritance tax and pensions, according to a separate item in the Family Office Almanac.
Cross-border advisory work has expanded as families diversify their domiciles and investment footprints. The US-UK corridor remains one of the most active routes for family office clients, driven by business ties, education links and property holdings in both markets.
Citywealth regularly publishes rankings and guides for the wealth advisory industry. The Transatlantic Select list represents a new vertical within its coverage, focusing specifically on advisors who manage the technical and logistical demands of serving families with presence in both the United States and the United Kingdom.
The full list of thirty names was published in the 22 July 2026 edition of the Family Office Almanac under the byline of Caroline from The Almanac Research Desk. No further details on individual advisors or firms were provided in the source material.
