Thomas Dubanchet French Qualified Tax and Estate Planning Attorney

I am a French tax lawyer specializing in international tax, with a particular focus on cross-border situations involving France and the United States.

I advise individuals, families and entrepreneurs on complex issues relating to French tax residence, relocation to France, trust reporting, estate and succession planning, and the structuring of investments and professional activities in a cross-border context. My practice is primarily dedicated to internationally mobile clients whose personal, family and financial interests span multiple jurisdictions.

Before founding my own practice, I worked with leading tax firms in Paris, Monaco and the South of France, where I developed extensive experience in international tax planning, private client work and contentious matters involving the French tax authorities. This background allows me to combine technical precision with a pragmatic understanding of how the French tax administration operates in practice.

I am particularly involved in advising U.S. citizens and residents moving to France, including on:

  • French tax residence analysis and timing,
  • Advance tax rulings (rescrits fiscaux),
  • Trust qualification and French reporting obligations,
  • Coordination of U.S. and French estate planning,
  • Investment structuring and ongoing compliance in France.

My approach is structured, fact-driven and strategic. I place strong emphasis on anticipating risks, securing positions upfront, and ensuring that legal structures are consistent not only on paper but also in their practical implementation. I do not offer generic solutions; each engagement is tailored to the client’s specific objectives, constraints and long-term plans.

I work closely with U.S. attorneys, CPAs, wealth planners and notaries to ensure seamless coordination between jurisdictions, and I see my role as that of a long-term advisor rather than a one-off technician.

Clients typically engage me when the stakes are high, the facts are nuanced, and clarity is required before taking action.

Bespoke Avocats is a boutique law firm dedicated to international tax and private client matters, with a strong focus on cross-border situations involving France and the United States.

The firm advises individuals, families and entrepreneurs facing complex questions relating to French tax residence, relocation to France, trust reporting, estate and succession planning, and the structuring of assets, investments and professional activities across jurisdictions.

Bespoke Avocats was founded with a clear objective: to provide high-level, tailored tax advice to internationally mobile clients, combining technical excellence with a pragmatic, real-world approach to French tax law and administration. The firm deliberately operates on a selective basis, handling a limited number of matters to ensure close involvement, consistency and strategic oversight on each file.

The firm’s work frequently involves:

  • French tax residence analysis and pre-move planning,
  • Advance tax rulings (rescrits fiscaux) with the French tax authorities,
  • Qualification and reporting of foreign trusts,
  • Coordination of French and foreign estate planning,
  • Structuring of French investments and activities for non-residents and expatriates,
  • Ongoing French tax compliance in an international context.

Bespoke Avocats regularly works alongside U.S. attorneys, CPAs, wealth planners, trustees and notaries, acting as the French tax anchor within broader international advisory teams. This coordinated approach ensures that strategies are not only technically sound but also aligned across jurisdictions.

The firm’s philosophy is clear: anticipate issues rather than react to them, secure positions upfront, and deliver advice that is both legally robust and operationally workable. Bespoke Avocats does not offer standardized solutions; each engagement is designed around the client’s specific facts, objectives and long-term plans.

Clients typically turn to Bespoke Avocats when clarity, discretion and precision are essential, and when the financial and personal stakes require careful, strategic decision-making rather than generic advice.
