Firm Description:

Advokatfirmaet Berngaard was founded 2007, as an innovative employer in a rigid profession. A clear alternative to the status quo. That is our history, and our future.

Our destination – our vision 

Berngaard aspires to be a recognised, attractive provider of cutting-edge expertise in our chosen fields; Real estate and Construction, Media and Technology, Public Sector and Start-ups and SMB. We strive to be cost-effective, not to maximise our own profits.

Our primary goal is always to help you, the client, to reach your goal. This requires a commercial understanding of the client’s actual requirements and a deep insight into the business and the legal framework. It’s that simple – and that hard.

We would get nowhere if we didn’t place people front and centre – either it’s our clients or our employees.

We’re ambitious and we want to create something great – which we all believe in and are passionate about. We want to grow, improve and get stronger – but not at any cost. Our employees are our most important resource. Happy employees who are proud of where they work provide the best legal services. We emphasise knowledge development and personal integrity. We will neither exploit our employees, nor those who come to us for advice.

In other words, Berngaard is a value-based law firm. Not just to be different for differences sake, but because we believe it pays off in the long run. We believe that the lawyers and legal talents of the future are motivated by more than just professional pride and money.

Our values

Our vision, our story and our values inform everything we do – how we hire and treat our employees, how we find new clients and how we treat those clients. We believe this way of thinking is the most sustainable in the long term. And it’s also fun.

Our values are balance, integrity and engagement. We believe these are the recipe for better results; for Berngaard, for our clients and finally, for society as a whole.


Enthusiasm, playfulness and drive are qualities we seek out and encourage, because they foster engagement. Personal and intellectual engagement, in turn, foster an inspiring environment for employees and clients alike. We believe this is the recipe for better results; for Berngaard, for our clients and finally, for society as a whole.


We strive for balance: Between lawyer and client, between work and home and leisure time, between career and personal development, between men and women, between partners and employees, between experience and youthful spirit, between legal minutiae and business sense, between the scope of a case and the work put into it, between helping existing clients and seeking out new clients.


Berngaard aspires to be a recognised, attractive provider of cutting-edge expertise in our chosen fields. This requires a high degree of personal and professional competence and integrity. Professional integrity flows from personal integrity. Its the basis and premise of everything we do, for everyone who works here. Seeking advice from Berngaard should feel safe and valuable. We are not afraid to speak our mind, but we are always looking for solutions.
