Van der Feltz Advocaten


Willem’s practice includes advising and litigating for various parties within the areas of planning and environmental law and real estate law. He advises clients both from a legal as a strategic perspective in projects or transaction. Eventual civil and administrative litigation is second nature to Willem. He specialises in spatial planning law, environmental law related to facilities (inrichtingen), REACH, substances of very high concern, land use policy (in particular expropriation, the Dutch Act on Preferential Rights of Municipalities (Wvg), long-term ground lease, and land exploitation), and energy law.

Willem acts on behalf of property developers, investors, businesses in the (chemical) industry, utility companies, and parties active in (sustainable) energy projects. His clients further include local and regional authorities, such as municipalities, provinces, and environment agencies.

Because of his broad range of expertise and experience, Willem quickly perceives strategic interrelationships, making him the right sparring partner for his clients. Also, his clients value his practical solutions and unambiguous language. Not to mention his extensive knowledge of the market and of the relevant areas of law which enable him to get to the heart of the matter quickly, and to find the right solutions for his clients.

Willem is the author of books on planning and environmental law (VIND Omgevingszaken (Grondexploitatie)) and administrative law (VIND Bestuursrecht (Wvg)), and multiple Dutch law journals regularly publish his comments on court decisions. Additionally, Willem enjoys lecturing on various subjects related to his practice (inter alia long-term ground lease on account of the Berghauser Pont Academy, and on land exploitation for the Dutch Academy for the Practice of Law (Academie voor de Rechtspraktijk)). In 2012, Willem completed the Grotius Academy course on Environmental and Planning Law with honours.
