About our law firm

StHM is dedicated to taxation as a priority, as well as to business law and real estate (town planning, property rights litigation).

Our expertise is strongly articulated on the Council (in personal and corporate taxation) and the relations with the administration, as well from a gracious point of view as litigation.

The expertise brought in is based on extensive experience from senior government bodies (Bercy, Court of Auditors, Taxation of the aviation sector).

As experts with great knowledge of the workings of the administration, our action is focused on supporting and helping people in difficulty facing administrative cogs or wealthy people wishing to fortify and optimize their heritage.


We have a strong comparative advantage compared to other tax lawyers less seasoned by the "informal" of the administrative services despite their technical qualities.

At StHM, we clearly rely on quality and services with high added value in terms of expertise.

Finally, we also offer banking investments in Luxembourg via a business network with a tailor-made and precision work just as if law was "haute couture".
