Notice of Defects: Tenant Rights in Germany

Dispute Resolution & Rent Reduction 2 min read · published September 07, 2025
As a tenant in Germany, you are often confronted with apartment defects, deadlines and questions about evidence. This article explains in practical terms how to write an effective notice of defects, which evidence (photos, logs, witnesses) is likely to hold up in court and which deadlines you must observe. We explain when rent reduction is possible, what obligations the landlord has (§ 535 BGB)[1] and how to prepare a court procedure at the local court (Amtsgericht)[2]. Concrete examples from big cities show how documentation and meeting deadlines affect the outcome. At the end you will find checklists, the relevant forms and information on authorities and courts in Germany. You will receive practical wordings for notices of defects, tips for collecting evidence and a timeline for submitting documents to the local court or mediation body.

What to do about defects?

If you discover a defect, inform the landlord in writing and set a reasonable deadline for remedy. Describe the defect precisely, give date and location, and request remedy. State possible consequences such as rent reduction if the defect is not fixed.

Detailed documentation increases your chances of success in disputes.

Securing evidence

Document everything promptly:

  • Photos with date and time
  • Correspondence and repair logs
  • Witness names and written statements
  • Notes on inspections and appointments
Keep copies both digitally and on paper.

Forms & deadlines

There is no single official notice-of-defects form, but for procedural steps you can find templates and forms at authorities (e.g. complaint forms for eviction suits). Use template wordings for written defect notices and observe deadlines for reporting and repairs.

  • Notice of defects (own wording, date, deadline)
  • Termination letter – templates and guidance (BMJV)[3]
  • Complaint / eviction suit – court forms
Respond in writing and within deadlines to preserve your rights.

FAQ

How do I report a defect correctly?
Always report defects in writing with a precise description, date, deadline for remedy and request a confirmation of receipt.
When may I reduce the rent?
Rent reduction is possible when usability is significantly restricted; the amount depends on the extent of the impairment.
Which court is competent?
In most tenancy disputes the local court (Amtsgericht) is competent; higher instances are the regional court (Landgericht) and the Federal Court of Justice (BGH).
