Challenging Excessive Rent: Tenant Tips in Germany

Rent & Rent Control 2 min read · published September 07, 2025

As a tenant in Germany, challenging an excessive rent can help dispute incorrect claims. This guide explains plainly how to avoid common mistakes: which documents matter, which deadlines apply, and which official forms or courts are responsible. I show practical steps from documentation to a possible lawsuit at the local court, including references to relevant sections of the BGB [1] and procedural rules of the ZPO [2]. The language remains simple for non‑lawyers so you can quickly decide when to challenge and how to enforce your rights in Germany. I provide sample wording, explain deadlines and show how to complete official forms or contact the competent local court.

When a challenge makes sense

A challenge is appropriate when you have reasonable doubts about the correctness of the requested rent or if the rent clearly exceeds the local comparative rent. First check your lease, the rent index and comparable offers, and note concrete reasons. Legal bases are found in the BGB [1] and for procedural questions in the ZPO [2]. For complex legal issues, clarification by the competent local court may be necessary [3], and higher court decisions by the BGH can serve as guidance [4].

Detailed documentation increases your chances of success.

How to draft the challenge correctly

  • Collect evidence (documents/records): secure photos, emails, payment receipts and handover records.
  • Check deadlines (deadline): bring the challenge within a reasonable time and document the date of delivery.
  • Use a form (form): prepare a sample challenge or formal letter to the landlord and send it by registered mail.
  • Consider court action (court): if no agreement is possible, consider filing a suit at the competent local court.
Respond to legal notices promptly to avoid missing deadlines.

How-To

  1. Step 1 – Documentation: Collect evidence, photos and payment records for rent and utilities.
  2. Step 2 – Drafting: Write a clear challenge with a request for correction and a deadline.
  3. Step 3 – Sending: Send the challenge by registered mail or documented email and note the date.
  4. Step 4 – Communication: Remain reachable, answer questions and record conversations.
  5. Step 5 – Court steps: If necessary, file a lawsuit at the local court and present your documents.

Frequently Asked Questions

What is a challenge against excessive rent?
A challenge is a written notice to the landlord stating that you consider the demanded rent too high and requesting a correction.
How long do I have to raise a challenge?
There is no uniform statutory deadline for every challenge; it is crucial to act promptly after becoming aware and to document deadlines, as procedural time limits may be relevant in court [2].
Which forms do I need?
There is no nationwide standard form for a challenge; use a written letter or a template from the competent justice portal and, if necessary, submit lawsuit forms at the local court [4].
