Mourant

Family offices with cross-border structures face a specific problem: finding a single firm that can handle the legal, fiduciary, and governance dimensions of their affairs across multiple offshore jurisdictions without fragmenting advice across separate providers. Mourant addresses this by combining law firm capability with governance and consulting services under one roof, covering the Cayman Islands, BVI, Jersey, Guernsey, and Luxembourg from nine offices globally.

For private wealth clients, Mourant’s offering spans the full lifecycle of offshore structuring:

• International trusts and private client legal advice across all five key offshore jurisdictions
• Fiduciary and trustee services, including acting as share trustee for orphan SPV structures
• Private wealth governance services covering trust administration, AEOI and international tax compliance, FATCA and CRS reporting, and accounting
• Litigation and dispute resolution for private wealth matters, including a dedicated private wealth litigation practice
• Company secretarial, corporate administration, and entity incorporation across jurisdictions

Mourant Governance Services acts directly as a licensed trustee and corporate service provider, not merely as an adviser referring to third parties. This matters for family offices that want a single counterparty accountable for both legal structuring and the ongoing administration of their offshore entities. The firm claims relationships with 90% of the world’s top 50 banks and advises 39 of the top 50 private equity firms, signals that it operates at institutional scale. Pricing is not publicly disclosed, and the firm’s depth is most relevant to families with genuine multi-jurisdictional complexity. Those with simpler onshore-only structures or a preference for a dedicated family office boutique may find the breadth of Mourant’s broader institutional client base a less direct fit.
