Specialists in administrative law

ENVIR Advocaten is the specialist in the fields of administrative law and environmental and planning law. Together, ENVIR’s lawyer have over 30 years of experience working in these legal fields at the highest level.

We know that the best legal solution need not always be the best solution for you. That is why we also have a keen eye for other interests. In addition to resolving problems and conducting litigation, we are also able to identify opportunities and risks at an early stage. What this means for you is that ENVIR can be an important sparring partner and adviser that actively and proactively helps you find solutions.

Our approach is practical and personal. The lines are short, we are readily accessible and we provide clear information. Our fees are flexible and competitive. Naturally, we will make clear arrangements with you in advance regarding the costs you may expect.


ENVIR specialises entirely in administrative law. This field of law regulates the powers of the government with regard to society in a wide variety of areas. In addition to general administrative law and administrative procedural law, we have a particular focus on planning and environmental law and nature conservation law. We frequently advise and litigate in these fields.

“We know that the best legal solution may not always be the best solution for you.”


ENVIR has a large network. We use that network to deliver the best solutions for you in other legal fields as well, such as civil (procedural) law, criminal law, corporate law and tax law.


Our clients are mainly companies and the (semi-) public sector, but we also serve interest organisations and private individuals. Thanks to our many years of experience, we have a thorough knowledge of administrative law processes and proceedings and the various contexts in which these take place. Our clients operate in or are involved in various sectors, including: industry, energy (including sustainable energy generation), aviation, real estate, schools, hospitals and infrastructure.
