Apply for public appointment and swearing-in as an expert

If you would like to be publicly appointed and sworn in as an expert, you can apply to the chamber responsible for you (e.g. IHK, HwK, Chamber of Agriculture, Chamber of Engineers, Chamber of Architects).

Important notes


Your application for public appointment and swearing-in as an expert depends on the following requirements:

  • There must be a general need for expert services for the subject area you have named. In this context, it is irrelevant how many experts there are already for the relevant subject area. The only thing that matters is whether the subject matter is of general importance. If it is a subject area for which experts have already been appointed in the past, the general need was already confirmed at the time and is therefore to be assumed.
  • You must provide evidence of your special expertise in the subject area you have named. This means that you must have above-average knowledge, experience and skills in the relevant subject area. In addition to evidence in the form of documents to be provided by you (certificates, expert reports you have prepared yourself, references, etc.), participation in an examination by an independent specialist committee made up of experts is also an option.
  • Finally, you must have the required personal aptitude. Your personal suitability can be assumed if you can guarantee that you will provide your expert services impartially, independently, objectively and in a manner that is understandable for the client. There should also be no doubts about your personal reliability and integrity. This presupposes that you have previously acted in accordance with the law and live in an orderly economic situation.

Documents required

  • Presentation of the services you offer and the (delimitable) subject area
  • Curriculum vitae with a description of your professional career
  • Proof of your special qualifications in the specified subject area (certificates, diplomas, seminar certificates, proof of employment, other certificates, etc.)
  • List of references, such as people (with address) who can provide information about your special knowledge
  • several (usually 3 to 5) reports that you have prepared yourself
    • You should deal with problems from the desired subject area and name solutions. The reports must be comprehensible and contain the necessary documents such as drawings, sketches, plans and photos.
  • training certificates
  • Declaration of assumption of fees and costs
  • for employees and civil servants: declaration of exemption
  • criminal record
  • Current certificate in tax matters (formerly tax clearance certificate) from the responsible tax office in the original.
