Application for public appointment and swearing-in as an expert in a field of architecture and construction

Applicants for public appointment and swearing-in must prove their personal and professional suitability in a specific subject area (e.B. damage to buildings) within the framework of a strict examination procedure. Experts are commissioned by private individuals, public authorities and, in particular, by courts to provide technical bases and assessments.Despite being commissioned by a specific person, the expert is not an interest representative. He or she is obliged to perform his/her task independently and on his or her own responsibility. In addition to the special specialist knowledge, special requirements are therefore placed on the personality and reliability of the expert.

Courts are obliged to commission publicly appointed experts as a matter of priority for the preparation of expert opinions.

Process flow

An application for a public order must be made in writing or online using the form provided. The above-mentioned evidence shall be attached to the application.

The examination of the special expertise and the ability to prepare expert opinions is carried out by a panel of experts.

The expert panel examines the expert opinions submitted. Furthermore, the special competence must usually be proven by an exam and an oral examination.

The Board of the Chamber decides on the public appointment on the proposal of the Committee of Experts.

The initial appointment is limited to three years. Subsequently, there is the possibility of extending the order by five years.

Who should I contact?

The responsibility lies with the Chamber of Architects of Lower Saxony.

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.
