When can you appeal?

An appeal or complaint is worthwhile if the new rent is clearly above the reasonable level for comparable new-builds or if there were formal errors in the notification. Check the lease and the Mietrechtsgesetz (MRG) for applicability and exceptions.[1]

Good documentation increases your chances of success in the procedure.

Which documents should you collect?

  • Lease agreement (document)
  • Payment receipts and bank statements (rent payments)
  • Photos of the apartment and defects (evidence)
  • Correspondence with the landlord (notice)

Deadlines and formalities

Pay attention to short deadlines: a written appeal should be submitted as soon as possible and all evidence attached. If you file a lawsuit, the procedure usually takes place at the competent district court; formal requirements and service deadlines apply that you should not miss.[2]

Respond quickly to court services to avoid losing your rights.
