Walter  Engelhart


I have been working at Van Benthem & Keulen since 1999 and have been a partner since 2010.
I head the construction and procurement practice group. 


At Van Benthem & Keulen, I started in contract law practice where I gained extensive experience in drafting and reviewing contracts as well as in negotiating and, where necessary, litigating on contracts. Quite quickly I specialised in procurement law. In addition to procurement law, I have specialised in civil construction law in recent years. One could say that in my practice field it is always about two (potential) contracting parties who want to, or have to, find each other. 

As a lawyer, I am first and foremost a service provider. For me this means that I act on the basis of the interests of my client and try to achieve the best conceivable solution. It is not only the legal aspects that play a role here. I am involved and conscientious. 

I regularly teach training courses and give presentations on topics within my area of expertise. Interaction and a great interest in the subject matter are paramount here.
