For complex cases, seek additional advice from legal services or local counseling centers. At the end you will find a step-by-step guide and frequently asked questions.

What does immediate termination mean for index rent?

An immediate termination ends the tenancy without observing the regular notice period when there is an important reason. For index rent, the agreement on adjusting rent to the price index must also be observed. Legal foundations can be found in the German Civil Code (BGB), e.g. on extraordinary terminations and index rents[1][2].

In many cases the local court decides on disputes in tenancy law.

When can tenants terminate immediately?

An important reason exists if it is unreasonable to expect the tenant to continue the tenancy until the end of the notice period. Typical reasons are arrears in payments, significant defects or serious contractual breaches by the landlord.

  • Arrears in rent payments despite reminder and deadline.
  • Significant defects in the apartment (e.g. heating failure in winter, severe mold) that are not remedied.
  • Serious breaches by the landlord, such as unauthorized entry or gross violation of privacy.
Respond to official letters in time, otherwise you may lose rights.

How do I write the immediate termination? Form and template

There is usually no legally prescribed form for an immediate termination. Formulate clearly: recipient, date, apartment address, explicit declaration of the extraordinary immediate termination with the reason and a request to return the keys. Attach evidence such as payment reminders, photos or expert reports as proof.

Example (short form):

"I hereby terminate the tenancy of the apartment [address] extraordinarily and immediately due to [reason, e.g. ongoing heating failure since date]. I request the return of the apartment by [date] and reserve the right to take legal action."

Always deliver the letter in writing with proof of receipt (registered mail or personal handover with confirmation). If unsure, state in the letter that you will set or have set a deadline for remedy.

Careful documentation increases the chances of success in court disputes.

What happens after termination?

If the landlord disputes the termination or demands eviction, they may file an eviction lawsuit at the local court. In such proceedings, the court examines whether the termination reason is sufficient and sufficiently evidenced. Inform yourself early about deadlines, objection options and required documents.

Frequently Asked Questions

Can I terminate immediately if the rent increases due to index adjustment?
A pure increase due to an index adjustment does not usually constitute an important reason for immediate termination; check your contract clause and seek legal advice if necessary.[1]
Which deadlines must I observe?
Respond promptly to reminders and deadlines; legal actions often have short deadlines. Set a reasonable deadline for the landlord to remedy defects.
Which documents help in court?
Collect rent payments, reminders, photos, expert reports, witness statements and written communication as evidence.
