In the Netherlands, minors (younger than 18 years of age) who own a business need permission from their parents for legal actions such as making a purchase or borrowing money. If you want to perform legal acts without your parents' permission and you want to be personally liable for legal acts performed in a commercial capacity, you can apply to the subdistrict court for limited legal capacity. You have to be at least 16 years old to do so. Limited legal capacity is not necessary in order to start a business.
Applying for limited legal capacity
You have to submit an application to the district court, specifically the subdistrict sector that is competent for your place of residence.
