We work with several external law firms within different fields and are used to high professional standards and high levels of service. However, we find that the labour law team in Arntzen de Besche is in a class of its own. In our experience they are a highly competent and skilled team who not only have deep insight into the legal issues at hand, but also have in-depth knowledge of our industry and our company. Through many years as a client, we also experience an unrivalled availability. We are always offered access to every resource, often on very short notice and at any time, day or night. This is for us a telling hallmark of a culture with strong customer orientation, something we put in high regard and appreciate. All of this makes Arntzen de Besche a particularly valued business partner for us.

The team is knowledgeable and gives practical and realistic advice.

Good at grasping the challenge and core of the situation and provide well-weighted legal advice which is easy to understand and implement.’

We would specifically like to highlight partner Knut Marius Sture. When he handles our cases we always feel confident that the matter is in the hands of someone we know will explore every possibility and go the extra mile to get the best result possible. He always delivers excellent work and consistently achieves results that are above and beyond our expectations. His insights, drive and contributions have on many occasions been invaluable for our company.’

Håvard Sandnes has good availability and gives initial feedback the same day. He works hands-on together with his senior associate.

Frode Martin Toftevåg has outstanding knowledge of the regulations regarding transfer of undertakings. This, combined with the fact that he quickly gets a good understanding of the business, gives him the ability to give swift and to the point advice and the necessary clarifications. This also means that we can proceed without any delay.

I have mostly worked with Håvard Sandnes and find him very professional (quick and to the point). He also has a sense of humour which makes it more fun to work with employment law.’
