Tenants: Prove Internet Outage in Urgent Proceedings Germany

Dispute Resolution & Rent Reduction 3 min read · published September 07, 2025

As a tenant in Germany, a prolonged internet outage can seriously affect the use of your home, especially for home office or online schooling. When quick legal action is necessary, an urgent proceeding can help achieve immediate measures or a rent reduction. This guide explains step by step which pieces of evidence are recognized by the court, which official forms and deadlines you must observe, and how to collect documentation in an orderly way. I describe concrete templates such as photos, log files, fault reports and witness statements, which local courts are responsible and which provisions of the BGB and the ZPO are relevant. The goal is that you can decide more confidently and act quickly. Concrete phrasing suggestions and authority links follow below.

What is an urgent proceeding?

An urgent proceeding is an accelerated court procedure that can obtain provisional legal protection; it is based on rules in the Code of Civil Procedure (ZPO).[2] For tenants this means: if the outage is urgent and a regular lawsuit would take too long, an application for interim relief can be filed at the competent local court. In the urgent proceeding the court examines whether an immediate intervention is justified and which evidence has been submitted.

An urgent proceeding can provide quick provisional solutions, but it does not always replace the main lawsuit.

Which evidence helps

The more specific and timely the evidence, the better. Collect records systematically and in chronological order.

  • Photos of error messages or network indicators with date and time
  • Log files or screenshots from router/modem with timestamps
  • Fault reports to the ISP (email, ticket number, provider response)
  • Date-and-time logs showing when services failed and when they resumed
  • Witness statements, e.g., from housemates or neighbors
Detailed documentation increases the chances of success in court proceedings.

Forms and templates

There is no uniform "rent reduction form" at the federal level, but for urgent proceedings and court applications use official form repositories and provide the court with clear, structured attachments. Typical documents include: a written defect notice to the landlord, a summarized evidence dossier and the application for interim relief at the competent court; official form collections and further guidance are available from authorities.[3]

Deadlines pass quickly; respond promptly to court requests.

Who is responsible?

For tenancy disputes the local court (Amtsgericht) is usually competent in the first instance; some decisions are appealed to the regional court (Landgericht). Important legal bases are in the German Civil Code (BGB), especially regarding landlord and tenant duties, and in the Code of Civil Procedure (ZPO) for procedure.[1]

Häufige Fragen

Can I claim rent reduction immediately because of an internet outage?
You can claim a rent reduction if the usability of the rented property is significantly impaired; the court decides individually on the amount and start of the reduction.
Do I have to inform the landlord before going to court?
Yes, you should inform the landlord in writing about the defect and set a deadline for remedy; this strengthens your position in court.
How quickly does the local court react in urgent proceedings?
The court can decide at short notice; dates and deadlines depend on the individual case and workload.

Anleitung
