Minouche worked at law firms with outstanding reputations both in Rotterdam and Amsterdam, before she decided to start her own firm.
Minouche was admitted to the Bar as attorney-at-law with Trenité van Doorne in Amsterdam in 1992. In 1996, she pursued her career with Loeff Claeys Verbeke. At the end of 1999, the Amsterdam branch of this firm merged with Allen and Overy. Initially, she focused her practice on spatial planning administrative law and environmental law. She then went on to expand her field of practice to new areas of administrative law, including legislation and regulations of markets, such as telecommunication, (sustainable) energy and food safety. The cases and matters she handles in these areas of law have as common factor that they involve complex environmental protection, technical and/or economic aspects.
Minouche is a member of the Association of Environmental Law, the Association of Environmental Lawyers, as well as the Association of Administrative Law. For several years, she sat on the board of the two last mentioned associations.
