We are Bosselaar Strengers Legal Partners, a close-knit team of enthusiastic lawyers who do everything we can to help our clients and their businesses.

What we believe in

At Bosselaar Strengers, we believe that practicing law is more than just a job. Does that sound a bit over the top? If you are not already one of our clients, we invite you to test this out. Then you will find out how much dedication we put into working on your case.

We believe that we can examine your case from an independent perspective and at the same time be entirely on your side. We believe that is the best way to help you. Because your interests are our interests. We perform best when we are able to advise you before your question or issue has got out of hand from a legal point of view. For in our experience, sound legal advice can prevent a lot of problems.

What we promise

We will be personally involved in your case from start to finish, we will help you think up solutions, we will give you advice while taking a broad view and, if necessary, we will conduct legal proceedings for as long as it takes. We work on serious matters but we are also able to put our work into perspective.

We promise that we will be clear: in our recommendations, in our use of language, about our costs and above all regarding how your case is progressing. We are easy to reach and are just as happy to visit you as to receive you at our offices.

Who we are

Bosselaar Strengers Legal Partners: dedicated and clear, experienced and ambitious.

Our background

Our firm’s history takes in some fine locations in Utrecht. Unfortunately, the records from the past do not tell us whether this explains our expertise in Property & Construction. Coen Bosselaar founded his law firm in 1949. In the 1970s, the firm moved to the canal-side street of Maliesingel. A quarter of a century after Bosselaar, Mark Strengers founded a law firm in Brigittenstraat. The two lawyers bumped into one another on a new development site when visiting new offices that could accommodate the respective firms’ growth plans. It was (corporate) love at first sight. The sensible Bosselaar and flamboyant Strengers had arranged a merger within a matter of weeks. Under the name Bosselaar & Strengers Advocaten, they built up one of Utrecht’s leading law firms at offices in Arthur van Schendelstraat. In 2009, the firm relocated to the Maliebaan avenue, and in 2019 we moved again to Euclideslaan in Rijnsweerd, where we continue to do our utmost every day to live up to our reputation.
