Challenging Excess Rent — Step by Step

As a tenant in Germany you should prepare a systematic complaint before considering legal action. Start with a clear statement why the requested rent is excessive and which sections of tenancy law are relevant (BGB §§ 535–580a)[1].

Collect evidence and documentation

Gather all documents that support your claim.

  • Photos of damage, room sizes and the apartment condition
  • Copy of the lease and previous rent increases
  • Bank statements, payment receipts and utility bills
  • Comparable rents, e.g. rent index or listings
Detailed documentation increases your chances of success.

Write the formal complaint

There is no nationwide official form for a complaint; usually an informal written letter with a concrete demand and deadline is sufficient. State clearly the allegedly excessive amount and explain your reasoning.

  • Name the concrete claim and the relevant period
  • Set a deadline by which the landlord should respond
  • Attach or refer to your evidence
Send the complaint in a verifiable way, e.g. by registered mail or with a delivery receipt.

Deadlines and the landlord's response

If the landlord does not respond or rejects the complaint, check deadlines for objection and possible next steps[2].

  • Determine common deadlines for objections or corrections
  • Decide whether to pay now, pay under protest, or withhold payment
  • Contact the landlord first and request an extension if needed

If it goes to court

If a lawsuit follows, the local court (Amtsgericht) is usually the first instance[3]; civil procedure rules (ZPO)[2] govern the process and later decisions by the Federal Court (BGH) may create precedent[4].

  • File a claim at the competent local court
  • Present and document evidence systematically
  • Observe deadlines and submit documents on time
Carefully weigh costs and benefits before filing a lawsuit.
