Sachkenntnis

Sachkenntnis (literally knowledge of the matter) is a term used in German law and professional practice to denote subject-specific knowledge and the ability to apply it within a given field. It signifies substantive competence about a particular topic and is distinct from general formal education. In everyday usage, it indicates that a person possesses the practical, recognized knowledge required to perform tasks safely, correctly, and in accordance with applicable rules.

In legal and administrative contexts, demonstrable Sachkenntnis is often a prerequisite for exercising certain activities. For example, in Germany the Trade Regulation Act (Gewerbeordnung) requires a Sachkundenachweis for some regulated trades—most prominently in §34c GewO for real estate agents, brokers, and property managers—intended to ensure knowledge of market practices, tenancy law, contract law, and consumer protection. The term also appears in firearms law as Waffensachkunde and in other domains where regulated handling of goods or services is entrusted to professionals.

Acquiring Sachkenntnis typically involves targeted training or certification, as well as a formal assessment or examination conducted or recognized by authorities or recognized professional bodies. It may be evidenced by certificates, licenses, or proof of passing exams that attest to knowledge and competence in a specific subject area.

Related terms include Fachkunde (subject-specific expertise) and Fachkenntnis (specialized knowledge), as well as general notions of competence and qualification. The concept emphasizes the practical, applicable knowledge necessary to perform tasks responsibly and lawfully.
