The Litigation firm

Solving your problem, so that you can continue with your business. That is what it is all about. It is our profession and our passion to make a business dispute or employment dispute manageable and to solve it. Sometimes we are able to do this by staying invisible by casebuilding the best file possible for and together with you behind the scenes. Being diplomatic where possible and aggressive where needed. And sometimes, full-on litigating is unavoidable. Because limits have been reached, because the other party remains unwilling to come to a constructive amicable solution, or because it may be important for your market reputation to draw a line.

Tailor-made service is key in the handling of each case. Because we are doing it together, lawyer and client. We invest in the mutual cooperation and we look in depth at your company and your market. BASE makes clear choices out of strength, because we only want to do what we are really good at and because you are simply counting on added-value. Therefor our practice focuses on Corporate & Commercial Litigation and Employment law.
