Lawyer for influencer marketing
What is the legal definition of influencer marketing?
Influencer marketing is now a central component of many companies’ marketing strategies. At the same time, courts and regulatory authorities have significantly clarified the legal requirements in recent years. Anyone working in this field—whether as an influencer, agency, or company—operates within a complex legal environment. Influencer marketing is not a distinct area of law in itself, but rather a practice-oriented focus at the intersection of media law, competition law, and contract law.
Legal responsibility does not lie solely with the influencer. Depending on the campaign structure and specific involvement, companies and agencies may also be held liable under competition law or media law. Clear contracts, approval processes, and compliance requirements are therefore important for all parties.
This includes, in particular:
- Drafting and reviewing influencer contracts and framework agreements
- Advice on advertising disclosures under the UWG, MStV, and DDG
- Compliance checks for campaigns and content
- Liability issues for influencers, agencies, and advertising companies
- Defense against and enforcement of cease-and-desist letters in the influencer sector
Media law services related to influencer marketing
As a media law attorney, I advise both sides: companies and agencies on structuring their campaigns in a legally compliant manner, as well as influencers and creators on contract negotiations, compliance issues, and defending against cease-and-desist letters.
Influencer Contracts
Drafting and reviewing influencer collaboration agreements, framework agreements, and individual bookings. Clear provisions regarding scope of services, compensation, usage rights, disclosure requirements, liability, and indemnification.
Advertising Disclosure & Compliance
Consulting on the legally compliant implementation of influencer campaigns. Consulting on proper advertising disclosures based on format and content, particularly under the Unfair Competition Act (UWG), the Interstate Media Treaty (Medienstaatsvertrag, MStV), and the German Digital Services Act (Digitale‒Dienste‒Gesetz, DDG). Compliance checks for campaigns and content prior to publication.
Consulting for Agencies
Legal support for agencies in structuring their campaigns, client relationships, and contracts with influencers and advertising companies. Indemnification clauses and limitation of liability.
Affiliate Marketing & Discount Codes
Consulting on the legally compliant design of affiliate programs and discount code partnerships. Disclosure requirements for commission‒based models and proper disclosure to the target audience.
Cease-and-desist letters in the influencer industry
Assistance with cease‒and‒desist letters under competition law regarding missing or incorrect advertising disclosures. Review, assessment, and advice on how to proceed—whether to issue a modified cease‒and‒desist declaration or to defend against the claims.
Social Media & Platform Law
Legal support in setting up social media accounts, dealing with account suspensions, and addressing questions regarding liability for content and the moderation of comments on Instagram, TikTok, YouTube, and other platforms.
Advertising Disclosure & Compliance
The requirement to label advertising is the central legal issue in influencer marketing. Promotional content must be clearly identifiable as such. Whether and how such labeling is required depends, in particular, on whether there is consideration involved and in what format the content is published. German law requires influencers to clearly label promotional posts. The requirements are scattered across various laws: the Unfair Competition Act (UWG), the Interstate Media Treaty (MStV), and the Digital Services Act (DDG).
Common questions about advertising labels
Clients come to me with these questions:
- Does every sponsored post have to be labeled as advertising?
- Is “ad” or “sponsored” sufficient—or does it have to say “advertisement”?
- Is our company liable if the influencer forgets to include the label?
- How can I protect my agency contractually against labeling violations?
- What should I do if I receive a cease-and-desist letter for failing to label advertising?
As a media law attorney, I can advise you on all matters related to advertising labeling—via phone or video consultation, or in person in Berlin.
Legal liability does not rest solely with the influencer who publishes the content. Depending on the structure of the campaign, companies and agencies may also be held liable. Clear contractual provisions regarding disclosure requirements, approval processes, and indemnification clauses are therefore important for all parties involved.
Why hire a lawyer who specializes in influencer marketing?
Influencer marketing intersects with media law, competition law, contract law, and data protection law. Legal requirements are evolving rapidly, and violations are consistently pursued by regulatory authorities and competitors.
Advice for both sides
I advise influencers and creators as well as companies and agencies. This ensures that contracts and campaign structures are legally sound for everyone involved.
An Overview of Labeling Requirements
Regulations governing advertising disclosures are constantly evolving. Incorrect or missing disclosures can quickly lead to warnings or regulatory proceedings. I can help you avoid these risks.
Practical Contract Drafting
Influencer contracts must not only be legally sound but also practical. Clear provisions regarding usage rights, compensation, liability, and compliance protect all parties involved and help prevent disputes.
Prompt response to cease-and-desist letters
Competition law cease-and-desist letters in the influencer sector are often time-sensitive. Specialized legal support enables a swift and well-informed response—whether to defend against unfounded claims or to enforce one’s own rights.
