Willem Van der Werf


Willem Van der Werf has significant expertise in the areas of construction, real estate, and government. Political and administrative authorities’ interests frequently play a large role in his practice. In particular, when it concerns development and transformation of a geographical area where public as well as private parties are involved.

Willem’s experience enables him to look beyond just the legal aspects of a matter and to assess related political and administrative law risks. By maintaining good and effective relations with the competent authorities, and by being cognisant of the context of administrative authorities, he achieves effective solutions for his clients.

Willem specialises in urban and spatial planning, real estate, municipalities’ right of first refusal, long-term ground lease and lease. In addition, he advises and guides municipalities on expropriation proceedings from beginning to completion. Willem is also experienced in addressing questions of law in the area of public administration, such as accessibility and integrity. He lectures at a number of educational institutions and is also an editor of the Dutch Journal of Agricultural Law (Tijdschrift voor Agrarisch Recht) and Kluwer's "Legal Practice Models" (Modellen voor de Rechtspraktijk).
