Structuring cross-border family capital.

Families whose members hold different passports and live in different tax jurisdictions cannot be served by a structure designed around a single residence. The mistake is rarely the choice of jurisdiction; it is the assumption that the choice made when the structure was set up will still hold when the next generation moves.

Residence is the variable that breaks structures. A trust that is efficient while the settlor is non-resident can become opaque and expensive the moment a beneficiary establishes residence somewhere with controlled foreign corporation rules or a deemed-distribution regime. The structure should be built to survive a move, which in practice means documenting the migration path before it is needed.

Governance matters more than the wrapper. A family constitution that sets out how decisions are made, how liquidity is provided to members who want out, and how the next generation joins the conversation, does more to preserve capital than any amount of jurisdiction arbitrage. The legal structure should implement that document rather than substitute for it.

Finally, reporting has quietly become the binding constraint. Common Reporting Standard exchanges, beneficial ownership registers and substance requirements mean that a structure which cannot be explained simply is a structure that will be expensive to maintain. Simplicity is now a tax planning strategy in its own right.
