Documenting AGG Complaints for Tenants in Germany

Discrimination & Equal Treatment 2 min read · published September 07, 2025
If you are a tenant in Germany and want to file a complaint under the General Equal Treatment Act (AGG), formal mistakes can endanger success. Many tenants are unsure which documents matter, how deadlines are calculated, or how a clear template letter should be structured. This guide explains step by step which documents and proofs help avoid common errors, how to document the timeline, and which deadlines apply when filing. We give practical examples and point to official forms and courts in Germany so you can assert your rights as a tenant calmly and effectively.

Typical mistakes with AGG complaints

  • Missing or incomplete evidence (evidence): photos, messages and witness statements are often absent.
  • Unclear timeline and missing dates (deadline): without dates statements are hard to verify.
  • Imprecise or missing template letter (form): no clear recipient or subject is named.
  • Deadlines missed or ignored (deadline): response deadlines are crucial.
Detailed documentation increases the chances of success in disputes.

Which proofs help

  • Photos and videos (evidence) with date and short description.
  • Written correspondence and messages (evidence): emails, SMS, chat logs.
  • Witness statements and contact details (evidence).
  • Medical certificates or expert reports for health effects.
Keep originals and backup copies stored separately.

Template letter: structure and wording

  • Short, factual subject line and clear date (form).
  • Specifically described incidents with dates and attachments (evidence).
  • Concrete request and a deadline for a response (court/deadline).
Respond to formal letters within deadlines to avoid losing rights.

Forms and authorities

The General Equal Treatment Act (AGG) regulates discrimination claims in Germany[1]. For tenancy matters, the provisions of the German Civil Code (BGB) are also relevant, especially duties of the landlord and protection against eviction[2]. In court disputes, the competent local court (Amtsgericht) is usually the first instance[3].

FAQ

Which proofs are important for an AGG complaint?
Photos, messages, witness statements, employment or tenancy contracts; state date and place.
Which court handles tenancy disputes?
For civil tenancy disputes the local court (Amtsgericht) is typically competent; higher instances include the Landgericht or the Federal Court (BGH).
Is there a deadline to file a complaint?
There is no uniform statutory deadline in the AGG; check limitation periods and act promptly to secure evidence.

How-To

  1. Gather all evidence (evidence): photos, messages, dates and witnesses.
  2. Check deadlines (deadline) and note every relevant date.
  3. Create a clear template letter (form) and send it by registered mail if possible.
  4. Contact the competent local court or the Anti-Discrimination Agency if necessary.

Key takeaways

  • Thorough documentation creates a clear evidentiary record and protects your position.
  • Deadlines matter; record all dates in writing.
  • A precise template letter simplifies communication with landlords and authorities.
