Mirjam studied Dutch Law (Master’s degree in Private Law) at the University of Groningen. Alongside her many years as a business manager of a medium-sized sauna and wellness complex, she worked for two years after graduating in the notarial profession, focusing on family law and corporate law.
In March 2019, she made the transition to the legal profession as an attorney and specialized in inheritance law (and tenancy law). As of 1 September 2025, Mirjam has been affiliated with Customs Knowledge as an attorney. Within the firm, she runs her own inheritance law practice and is also active in the field of customs law.
Within the customs law practice, Mirjam advises and litigates on behalf of companies in a wide range of customs-related matters. These include the application and interpretation of customs legislation, export control and sanctions, disputes with customs authorities, objection and appeal proceedings, as well as issues at the intersection of customs law and civil law. Her background in civil law and experience in corporate law enable her to approach customs matters in an integrated manner, with attention to commercial interests, contractual relationships, and potential liability risks.
Mirjam is known for her structured and practical approach. She translates complex regulations into clear and workable advice and carefully guides clients through procedures and strategic decision-making. This makes her a reliable sparring partner for companies and organizations, both in preventive advisory work and in customs-related disputes.
For Mirjam, good communication, expertise, and commitment are essential. She understands that inheritance law can be legally complex, often during a period when a death also brings strong emotions. A good attorney can then provide calm and clarity by explaining matters clearly, outlining the (im)possibilities, and taking into account all (underlying) interests. She applies this same approach in her customs law practice, where clarity, predictability, and careful balancing of interests are essential for businesses.
Mirjam works from the firm’s office in Heerenveen, close to where she lives. She enjoys both winter sports and sunny destinations. In her free time, she enjoys walking, running, and playing tennis—both on the court and off the court as secretary of the Ten Woude tennis club. She also enjoys playing games at home, dining out, and spending a lot of time with family, her household, and friends. If there happens to be any time left over, she most enjoys horseback riding, doing puzzles, and sailing a catamaran.
Mirjam is registered in the legal practice areas register of the Netherlands Bar Association under the practice area of Inheritance Law. Based on this registration, she is required to obtain ten continuing education credits each calendar year in this registered practice area, in accordance with the standards of the Netherlands Bar Association.
