“A good lawyer has commercial business acumen and insight into the client’s needs. In this way, value-adding advice is provided– both now and in the future”

With Marc as your advisor, you get solid legal advice with an overview, commitment and attention to detail. Marc also acts as a commercial sparring partner with an eye for innovative solutions.


Marc is a versatile, business-oriented lawyer with specific skills during all phases of construction and in all areas of construction law. He advises market players throughout the construction process, whether they are contractors, consultants or developers.

Marc has solid experience in general commercial consulting, drafting of contracts, procurement and dispute resolution, including preparation and conduct of court proceedings both before the civil courts, the Danish Building and Construction Arbitration Board (Voldgiftsnævnet for bygge- og anlægsvirksomhed) and the Complaints Board for Public Procurement (Klagenævnet for Udbud)

Marc also has broad business law insight and experience, which means that he also aims to be a creative, commercial partner for his clients and not just a “problem solver”. His focus is always on providing value-adding and useful advice to clients in close and active cooperation.
