Data protection

Data protection is vital to us. The notaries assign the utmost importance to the protection of your personal data.



We process your personal data only insofar as is necessary for the contact you have requested or for the provision of the notarial services you have commissioned or insofar as is required by law. Moreover, notaries are bound to special duties of professional secrecy under Section 18 Federal Code for Notaries (BNotO). This secrecy undertaking extends to all of our employees as well. A breach of the notary's duty of professional secrecy is punishable by law as a rule. Within the scope of our legal obligation, we have concluded appropriate confidentiality agreements with external service providers or processors in order to ensure your protection.
