Termination by Tenant 3 min read · published September 07, 2025

As a tenant in Germany, you often face questions during modernisation works: When can you terminate, what deadlines apply and which forms do you need? This guide explains clearly what rights and duties tenants have, how to submit a timely termination after modernisation correctly and which proofs are helpful. You will learn step by step how to check deadlines (deadline), collect evidence (evidence) and serve the termination validly. I also show which courts are competent and where to find official forms. All information is based on German law and refers to relevant paragraphs and authorities so you can act with confidence.

When does termination after modernisation apply?

Tenant termination is possible if the modernisation significantly impairs the use of the apartment or makes it unreasonable. The scope of the work, duration of the impairment and concrete burdens such as lack of heating or substantially reduced living space are decisive. Legal foundations can be found in the BGB, especially regarding written form and deadlines.[1]

In many cases, written documentation is the central evidence for your claim.

Deadlines, form and evidence

Three points are important: complying with the notice period, the written form and sufficient evidence. The termination must be in writing and personally signed. State the reason and the affected periods in the letter. Collect photos, defect reports to the landlord and, if necessary, medical or expert reports as proof.

  • Check the statutory notice period (deadline) and any deadlines in the lease agreement.
  • Prepare a written termination letter (form) with your signature.
  • Collect evidence: photos, emails to the landlord and defect logs (evidence).
  • If necessary, prepare documents for the local court (court).
The more complete your documentation, the stronger your position in a dispute.

What a termination letter can look like

There is no binding official form for tenant termination, but written form is required. In the letter, include: your address, date, rental property address, clear notice of termination, reason (e.g. prolonged unreasonable impairment due to modernisation), desired termination date and your signature. Example: "I hereby terminate the tenancy for the apartment Musterstraße 1, 12345 City, on DD.MM.YYYY due to prolonged unreasonable impairment from modernisation works." Attach evidence as enclosures.

Keep a copy of the termination and the proof of dispatch.

If the landlord objects or there is a dispute

If the landlord does not respond or objects to the termination, you may consider legal steps. Local courts (Amtsgerichte) are generally competent for tenancy disputes; higher instances include regional courts and the Federal Court of Justice.[3] Check whether legal aid (PKH) is an option and use official application forms if necessary.[2]

Respond to letters from the landlord or the court within deadlines to avoid disadvantages.
