In short
Missing ad disclosure can lead to a cease-and-desist letter with an injunction and cost risk, plus a fine procedure by the state media authority with fines up to €500,000. The actual amount depends on severity, reach and repetition — first offences are usually far lower.
What are the concrete consequences?
Missing or insufficient disclosure can trigger two independent procedures. Both can also run in parallel.
| Route | Who | Consequence |
|---|---|---|
| Cease-and-desist (UWG) | Competitors, associations, competition watchdog | Injunction declaration, legal-cost and penalty risk |
| Fine (MStV) | State media authority | Fine up to €500,000, prohibition order |
How high are the fines really?
The €500,000 ceiling is the legal maximum, not the norm. Authorities set the fine by severity, account reach, intent or negligence, and repetition. A one-off, later-corrected violation by a small account is typically treated more leniently than repeated, deliberate hidden advertising with large reach.
What happens with a cease-and-desist letter?
It usually demands a penalty-backed injunction declaration and reimbursement of the sender's legal costs. Once signed, every further violation can trigger a contractual penalty. Signing rashly can be costly — legal review is advisable.
How do you avoid penalties?
- When in doubt, always disclose — with "Werbung" or "Anzeige".
- Place the label clearly at the start, not buried in hashtags.
- Document collaborations so consideration and terms are traceable.
- Don't sign a cease-and-desist letter unchecked — get legal advice.
Both procedures can coincide
Cease-and-desist and fine are not mutually exclusive. One violation can be pursued under civil law and sanctioned under media law at the same time.
