What to do first

Quickly make a clear record: keep the lease agreement, recent payment receipts and the written notice of the increase. Note dates and conversations with the landlord and the landlord's reasons for the increase.

Keep all receipts and documents organized and safe.
  • Collect the lease agreement, payment receipts and the written notice of the increase.
  • Take photos or copies of all relevant communication with the landlord.
  • Check whether the increase is index-based or based on another agreement.

Correction request and appeal

Before legal action, send a written correction request to the landlord. Explain clearly why you consider the increase unreasonable or incorrect, attach evidence and propose an alternative or request further clarification. Mention references to applicable law if you know the provisions.

A written correction request increases your chances of success in a later dispute.

What to include in the correction

  • Describe events chronologically and attach payment receipt copies.
  • Refer to lease terms and any relevant legal provisions.[1]
  • Set a reasonable response time for the landlord, for example 14 days.

What to do if correction is ignored

If the landlord does not respond or the increase remains, the next step may be to take the matter to district court. Before that, seek advice and assessments from consumer advice services or legal aid. Legal procedures require careful documentation and possibly lawyer assistance. If you pursue litigation, ensure you follow legal deadlines and requirements.[2]

Act quickly within deadlines so you do not lose rights.
