Banking and Financial Law
DSM’s Banking and Financial Law practice team advises on a wide range of financial transactions governed by Luxembourg law, involving Luxembourg and foreign entities or in respect of Luxembourg-based assets.
Representing and advising both lenders and borrowers, collateral providers and pledgees, we provide legal assistance for financing and the taking of security, not limited to comprehensive structuring, tax and ancillary aspects of traditional corporate finance but extending to more complex financing arrangements and hybrid financial instruments. We have extensive experience in advising financial institutions and other professionals in the financial sector on all aspects of client contractual relations and documentation, professional liability, criminal financial law liability, corporate governance and the protection of personal data.

DSM’s Tax team advises corporate clients on a wide range of international transactions, investment structures as well as on day-to-day business matters in Luxembourg. We not only represent  Luxembourg companies, shareholders

We assist our corporate and private clients in the administrative pre-litigation phase of tax dispute proceedings (réclamation contentieuse, recours hiérarchique, recours grâcieux).

In particular, DSM’s Tax team provides tax advice to alternative investment funds (including SIFs, SICARs and securitisation vehicles), private equity houses, banking institutions as well as industrial and commercial groups.
