Communication and campaign advice

“Share and win” or “like and win.” Social media is full of online contests that advertisers use to try to get consumers’ attention. But did you know that the vast majority of those contests and promotions violate at least one or often several legislations?

Consumer protection, gambling laws, GDPR and e-privacy laws impose strict rules on what is and is not allowed in the context of advertising campaigns and (online) promotions. We are happy to guide you through the maze of rules and regulations.

Advertising and marketing are our natural habitat. We are the legal partner of UBA (United Brands Association) for a reason. As the only law firm in the country, we chose to strengthen our expertise with an (online) marketing consultant who has 20 years of experience in the media, marketing and the world of advertising. This allows us to offer you tailored legal advice that is based on solid knowledge and expertise. 

Sirius Legal has built a strong track record in advertising law in recent years and successfully provided legal advice to small and large advertisers, advertising agencies and online agencies. You can contact us for:

  • Advertising campaigns
  • Contractual negotiations
  • Disputes in or out of court
  • Advice and contacts with governmental authorities and agencies 

We closely monitor all technological developments that could impact our clients to ensure we grasp the legal implications of such changes before the market does. Marketing automation, customer data platforms, the use of AI in advertising, the shift to cookieless advertising and the disappearance of third-party cookies, the rise of server side tracking, the impact of Google Consent Mode on your data compliance … We do not only keep an eye on the situation, but also actively participate in the discussions around new technologies and the future of the marketing world.

You can also contact us for more traditional advice in advertising law. We will gladly help you with all your questions about: 

  • Advertising campaigns (in practicular, trademark law, copyright, comparative advertising, privacy, product placement, sponsorship agreements, questions about social media, native advertising)
  • Online and offline competitions and promotional campaigns throughout Europe
  • Contest regulations
  • The construction and use of databases, privacy, database rights, opt-in, opt-out, scrapping or crawling of data, the use of rented or purchased databases

More about media and advertising

Audiovisual production

Technological evolutions and a changing media landscape bring new legal challenges. Copyright protected works, production contracts and media are growing with the times, but are you still up to date?


We understand your love for your own book; after all, we write books ourselves. Good contracts around copyright are craftsmanship. Get some peace of mind with a strong (publishing) contract.

Agency/advertiser relationship

Verbal agreements work well until they go wrong. Professional cooperation in advertising is conducted best on the basis of solid contracts. What about your campaigns? Are they certainly legally compliant?
