Registering a domain name solely in order to sell it with a large profit margin is not contrary to the law in and of itself.
Only “abusive registration” of domain names is not permitted by law. Under abusive registration the law understands registering a domain name to which no right or legitimate interest can be asserted, with a view to harm a third party or to obtain an unfair advantage, if that domain name is identical or very similar to someone else’s brand, trade name, company name, family name, original work, geographical indication, etc.
Assessing whether the registration of a certain domain name is abusive is the exclusive competence of the courts or the accredited alternative dispute settlement institutions and not of DNS Belgium.
