Netherlands > Banking and finance: lender or arranger side

Firm overview: Meet Dirkzwager, where legal and tax specialists provide integrated services. Dirkzwager was founded 137 years ago and is the 12th largest law firm in the Netherlands (2022). With offices in Arnhem and Nijmegen and approximately 170 legal experts (attorneys-at-law, notaries, candidate notaries and tax consultants), Dirkzwager possesses specialist expertise in almost every field.

Full service approach: Dirkzwager aims to be a guide to the world of law. That is why we opt for an organic approach. Our teams and organization operate flexibly and are constantly adapting. To every assignment, job or client. We grow with clients when necessary, and change course when it makes sense. But always with a clear and common goal in mind: to solve complex legal and tax issues for our clients.

Thanks to our focus on multidisciplinary teams and sharing of specialist knowledge, we maintain a comprehensive, up-to-date overview of our profession. This way we are able to ensure that our clients are provided with service effectively, promptly and cost-effectively. This also applies where international interests are involved.

Dirkzwager works with its clients as business partners and not simply as suppliers of legal and tax services. It commits to excelling not only in its individual areas of practice, but in the way it delivers service to its clients — with enthusiasm, effort and integrity.

The firm serves as its client’s legal and tax trusted advisor, helping clients achieve their business objectives while managing their risks, difficulties and expenses.

Furthermore, Dirkzwager takes great pride in not only knowing its client’s industries but also understanding their unique business process. The firm offers full legal and tax services in the Netherlands. In addition, it offers legal services in Germany through its own German desk run by both Dutch and German accredited attorneys.

International collaboration: Dirkzwager works for regional, national and international clients. Multinationals often entrust us with their legal affairs. These include corporations with a Dutch holding company, foreign operating companies or business units in the Netherlands. From our own region, but also from further afield.

Through our German Desk and the TELFA (Trans European Law Firm Alliance) and USLAW network, Dirkzwager is able to assist its clients in all EU countries as well as all 50 US states. As members for the past 30 years, Dirkzwager has worked closely with most affiliated firms from the network.
