What is the special termination right for index rent?

With index rent, the amount of rent is tied to a price index. A special termination right may be considered if the index adjustment leads to an unreasonable burden or if contractual agreements provide exceptions. Relevant legal bases can be found in the BGB, in particular the general rules on the tenancy relationship and termination.[1]

Detailed documentation increases the chances of success in disputes.

When can it apply?

  • In cases of financial hardship or sudden hardship due to index jumps (documents)
  • If contractual clauses provide for special termination at certain index values (documents)
  • In case of calculation errors or lack of transparency in billing
Respond quickly, because deadlines can affect your rights.

Which pieces of evidence help?

  • Tenancy agreement and all amendments (documents)
  • Bank statements and payment receipts showing increased burden (payment)
  • Correspondence with the landlord and settlement statements (record)
  • Photos or expert reports for defects that justify a rent reduction or special termination (photo)
  • Witness statements or written confirmations from third parties (record)

Forms and authorities

There is no uniform nationwide official form for a special termination in the case of index rent. Tenants usually write a formal termination letter with date, contract details, reason for termination and a clear signature. If you need to prepare for court proceedings, documents are filed with the competent local court. Please refer to the official regulations for information on court procedures and jurisdiction.[2]

Send the termination by registered mail with return receipt to prove delivery.
