Tenant Documents & Deadlines for Algorithm Bias in Germany
As a tenant in Germany, you may be affected when landlords or housing platforms make automated decisions that appear discriminatory. This practical section explains which documents to gather (emails, lease agreements, screenshots), which deadlines apply for reports and appeals, and how to systematically document indications of algorithm bias. I show concrete steps for filing a complaint with the Federal Anti-Discrimination Agency, which legal bases (e.g., AGG, BGB) are relevant, and when a case before the local court becomes sensible. The text avoids legal jargon and helps you meet deadlines and preserve evidence so it can be used in court. At the end you will find a how-to with practical reporting steps and sample phrasing.
Which documents should tenants collect?
Collect everything that evidences actions, decisions, or communications. The more complete the documentation, the stronger your position.
- Copy of the lease agreement and any addenda.
- Emails, messages and platform notifications (as screenshots and original files).
- Payment receipts and bank statements if decisions are linked to payments.
- Photos or videos that show the condition of the dwelling or relevant facts.
- Notes of conversations (date, time, participants).
Key deadlines and timelines
Act quickly: deadlines often determine whether a claim is enforceable later. Court deadlines follow the Code of Civil Procedure and can be tight.[2]
- Deadline to secure evidence: immediately, while documents remain available.
- Deadline for extrajudicial complaints to authorities: usually within a few weeks after the incident.
- Statutes of limitation for legal claims: check, as they vary by claim.
Quick overview: steps to report
Use a clear order: document, formalize, report, and, if necessary, litigate.
- Secure evidence immediately (emails, screenshots, payment records).
- Summarize the indications in a short chronology.
- File a complaint with the Federal Anti-Discrimination Agency or the landlord in writing.
- If extrajudicial measures fail, consider a claim before the local court.
Legal bases and courts
For discrimination issues the General Equal Treatment Act is relevant; tenancy obligations are in the BGB. For court disputes, the local court, higher regional court, and the Federal Court of Justice are the competent instances.[1][2]
Important official forms and templates
Many reports start with an informal letter, but there are official contact points and templates:
- Complaint form of the Federal Anti-Discrimination Agency (use the contact form for initial reports; describe the incident and attach evidence). Federal Anti-Discrimination Agency (contact)
- Filing a lawsuit: you will need a statement of claim under the Code of Civil Procedure; the local court will inform you of required documents.
