Which deadlines apply?

The main rules come from the Mietrechtsgesetz (MRG).[1] For tenants, deadlines are often binding and can decide whether an application is still admissible. Check your rental documents and deadlines early.
  • Application to determine the rent: within 30 days (days) after becoming aware of the defect or the excessive rent.
  • Response to formal letters from the landlord: usually within 14 days (days) of receipt.
  • Filing a lawsuit or application at court: deadlines vary; submit documents early to avoid procedural disadvantages.
Respond to written communications on time, otherwise you may lose rights.

Evidence and formal requirements

For determining a fair rent, thorough documentation is essential. Observe deadlines and formal requirements, especially for written notifications and claims.
  • Document rent payments (rent): collect bank statements, receipts and payment records.
  • Observe written notification and form requirements (form): send proofs by registered mail or documented email.
  • Secure photos, protocols and witness statements (evidence) as evidence and date them.
Keep all payment receipts and correspondence organized.

Court procedure and deadlines

If an agreement with the landlord cannot be reached, proceedings at the district court may be necessary.[2] Deadlines for claims and the form of submission are regulated by procedural law; inform yourself early about jurisdiction and required documents.
  • Submit application: check deadlines and form requirements before filing.
  • Attend to deadlines: note submission and possible supplement deadlines (days).
  • Prepare evidence properly and submit it to the court (evidence).
In many cases the district court decides on the appropriate rent.
