Rent & Rent Control 3 min read · published September 07, 2025
Many tenants in Germany face the question of whether a demanded rent is too high and how to dispute or challenge it. This text explains in plain language what rights long-term tenants have, which steps are necessary for review and documentation, and how to meet deadlines. You will learn when a formal complaint is sufficient, when a rent reduction is possible and how proceedings before the local court proceed. The language is practical and free of legal jargon so that, as a tenant, you know which documents are important, which official forms may be needed and which authorities or courts are responsible. At the end you will find concrete action steps and pointers to sample templates as well as links to official legal texts and courts.

When is a rent excessive?

A rent is excessive if it is significantly above the customary local rent or violates legal limits. Legal foundations can be found in the German Civil Code (BGB), especially regarding tenant and landlord duties and rent levels[1]. Key indicators include:

  • Deviation from the customary local rent according to local rent indexes or expert reports.
  • Rent increases above permissible percentages for step rents or index rents.
  • Missing or unclear agreements in the lease about ancillary costs and operating expenses.
The most important benchmark is often the local comparative rent.

How to complain and challenge: practical steps

First check the contract documents, compare the rent with the rent index and collect evidence (previous statements, ads, photos, payment receipts). Documentation is crucial if you want to formally challenge the claim or assert a rent reduction.

  • Collect evidence: lease, last utility bill, repair records and payment receipts.
  • Check deadlines: notices and lawsuits are subject to deadlines you must meet.
  • Send a written complaint or request for correction by registered mail or courier.
  • Contact the landlord and document outcomes in writing.
  • If no agreement is reached: prepare for proceedings before the local court, including the statement of claim.
Keep all correspondence and payment records together in a folder.

Forms and templates (officially oriented)

There are no nationwide mandatory forms for many steps, but template letters and guidance are practical. Examples:

  • "Termination/complaint template" for warnings or complaints (use a dated, signed letter and proof of dispatch).
  • Statement of claim according to the Civil Procedure Rules when filing at the local court; the ZPO governs procedure and form[2].
Do not submit unreviewed templates: adapt statements to your situation and attach evidence.

What happens in court and which authorities are responsible?

Many tenancy disputes are handled by the local court; appeals go to the regional court and, for precedent-setting issues, to the Federal Court of Justice (BGH)[3]. Procedural rules and deadlines follow the Civil Procedure Rules (ZPO)[2]. Typical steps:

  • File the claim in writing at the competent local court.
  • Court settlement hearing or written procedure, evidence by documents and witnesses.
  • Judgment and possible appeal to regional court or review at the BGH for fundamental issues.
Detailed evidence documentation often determines the outcome.

FAQ

How do I draft a complaint about excessive rent?
Write a dated, signed notice to the landlord with a concrete justification (comparative rent, rent index, concrete figures) and request correction within a deadline.
Can I withhold rent if I think it is too high?
Withholding rent is risky; better to send a written complaint and, if necessary, deposit the disputed amount in escrow until resolved.
Which court is competent?
Usually the local court; the Federal Court of Justice decides on questions of principle.[3]
