The Official Authorization Letter (Vollmacht) is a crucial legal instrument in German business and personal affairs, founded on provisions in the German Civil Code (BGB §§ 164-181). This document is essential when one party needs to delegate authority to another for various purposes, including business transactions, administrative proceedings, or personal matters. The authorization letter must clearly specify the scope of powers granted, the identities of both principal and agent, and any limitations on the authority. It's commonly used in situations ranging from simple administrative tasks to complex business transactions, and may require notarization depending on its intended use. The document's format and content must comply with German legal requirements, particularly regarding clarity of authorization scope and proper party identification. For certain applications, such as dealings with government authorities or real estate transactions, specific additional formal requirements may apply under German law.

2. Principal Identification: Full legal name, address, and identification details of the person granting the authority

4. Scope of Authority: Clear and specific description of the powers being granted to the agent

5. Duration: Period for which the authorization is valid, whether it's indefinite or has an expiration date
