Services

  • Classical Services
  • Succession Planning
  • International tax laws

We provide professional advisory and consultancy services both in tax questions and regarding economic targets to private persons, freelancers and companies of all sizes and legal forms.
In this, we are cross-sectoral and work for all professional groups.

Management Consulting is becoming more and more important for every enterprise, so it is one of the activities we focus on.

Management Consulting should not start just then when an enterprise is already in a crisis but should accompany it with an eye to the future. In our understanding, the target of Management Consulting is to avoid a crisis.

Our work as lawyers is focused on economic efficiency.

Together with you, we weigh up the measures that are sensible in consideration of the costs risk. What good is it to you to win a lawsuit if the opponent is unable to pay?
