Use Online-Service
The certification of a signature is only possible for submission to an authority. A personal interview is required for this! Official notarizations are not possible for private documents that are to be used privately. Signature authentication for other purposes or public authentication (§ 129 BGB), as well as signatures without associated text can be requested from a notary.

Important notes
Prerequisites
The signature is certified if the document is to be submitted to an authority or other body due to a legal provision.
Documents required
- ID card or passport
- Document on which the signature is to be authenticated.
Please note
A certification is based on the certificate or document and is not personal, which is why a non-affected person can apply for it without a power of attorney.
