Question of the day:
«"Alexis, I have assets in Singapore, an apartment in Lyon, and I'm moving to London soon. Who can coordinate all of this without me being subject to double taxation?"»
This issue, which I deal with daily at Balmont Conseil, perfectly illustrates the complexity of the wealth management for international expatriates.
In a world where the geographical mobility As the pace of change accelerates, your wealth can no longer remain static or confined to a single border.

The challenges and specificities of multi-jurisdictional wealth
Managing assets spread across multiple countries requires expertise that goes far beyond traditional financial advice. The challenges are threefold:
- Legal certainty: Conflicts of laws between civil law (France) and the Common Law (Anglo-Saxon countries) can paralyze transmission.
- Tax efficiency: Mastering the international tax treaties is vital to prevent each country from taxing the same income.
- Asset portability: Your assurance-vie contracts or your holding structures must be able to follow you without generating massive tax friction.
