Authentication of signatures

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.

  • ID card or passport
  • Document on which the signature is to be authenticated.


The signature is certified if the document is to be submitted to an authority or other body due to a legal provision.


Certification is based on a certificate or document and not on a person-related basis, which is why a person not affected can apply for this without a power of attorney. Certifications in the area of private law (e.g. certification of a travel authorization for minors) are generally not permitted in the customer centers. Please contact a notary for this.
§34 (1) Administrative Procedure Act (VwVfG)
