Experts in the craft sector Public appointment and swearing-in

Publicly appointed experts in the craft sector are characterized by special expertise, objectivity and trustworthiness. They shall be subject to supervision by the competent authority.

Publicly appointed experts are all persons who have been appointed and sworn in by a public institution. According to the Crafts Code (HwO), it is the task of the competent authority to appoint and swear in expert persons for the reimbursement of expert opinions on goods, services and prices of craftsmen and of craft-like trades.

The basis and requirements for the public appointment and swearing-in result in detail from § 91 paragraph 1 no. 8 HwO, the expert regulations (SVO) issued by the competent authorities and the general trade law provisions of §§ 36 and 36a Gewerbeordnung (GewO). The SVO determines the selection and appointment procedure according to which the competent body carries out the public appointment, standardises the rights and obligations of the experts and regulates the legal relations between expert persons and the competent body.

Who should I contact?

Responsibility lies with the Chamber of Crafts (HWK).

This procedure can also be handled through a "point of single contact". The "Point of Single Contact" is a special service offered by the municipalities and the state for service providers.
