Publizitätswirkung

The publicity effect of the commercial register plays a central role in German commercial law, ensuring legal certainty and transparency in business transactions. Through the publicity effect, facts registered in the commercial register are legally bindingly disclosed to third parties, who may therefore rely on their accuracy. A distinction is made between positive publicity according to § 15 para. 1 HGB, whereby registered and published information—such as the company name, registered office, or authorization to represent a GmbH—can be asserted against any company and contractual partner. In addition, there is negative publicity according to § 15 para. 3 HGB: If a mandatory registration is omitted, a bona fide third party may assume that the relevant fact does not exist. Example: If a new managing director is not registered, the company remains liable for the former managing director. Thus, the publicity effect protects third parties from hidden risks, reduces liability issues, and strengthens trust in the German corporate landscape. For entrepreneurs, this means a strict obligation to register all changes relevant to the register to avoid costly legal consequences and secure their own reputation. Moreover, the publicity effect improves the efficiency of M&A processes and credit assessments, as banks and investors can quickly access reliable data.
