Document Water Damage: Tenant Guide Germany

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

Many tenants in Germany are unsure how to collect evidence and meet deadlines after water damage so that claims against the landlord or insurer are enforceable. This guide explains step by step how to document damage factually, completely and in a court-proof manner, which immediate measures make sense, and which deadlines apply. It is aimed at tenants without legal expertise and lists relevant laws and official authorities so you can observe deadlines, use forms and, if necessary, resolve matters at the local court. Practical examples show how photos, logs and written defect notices work.

Why court-proof documentation matters

Court-proof documentation protects your rights as a tenant: it proves the extent and timing of the damage, shows you acted appropriately, and makes it easier to claim repair costs or rent reduction. The landlords maintenance duties are regulated in the German Civil Code (BGB) §§ 535 et seq.[1] If deadlines are missed or evidence is missing, claims are hard to enforce.

Detailed photos and a complete damage log strengthen your case.

Immediate actions after water damage

  • Stop the water source or shut it off and, if necessary, disconnect power in affected rooms.
  • Take photos and videos of all affected areas, save date and time in the file name.
  • Send a written defect notice to the landlord or property manager and document receipt.
  • Contact the property manager and your liability or household insurance to report the damage.
Respond quickly: reporting deadlines can affect your claims.

Collecting and organizing evidence

Collect different types of evidence: photos, videos, witness statements, invoices for temporary measures and a continuous log with date, time and description. Keep original invoices and estimates.

  • Photo documentation: wide shots, close-ups of damage, a reference item (e.g. tape measure) for scale.
  • Damage log: date, time, location, cause (if known) and measures taken.
  • Invoices and estimates from tradespeople or drying companies.
  • Witness contacts: names and short statements from neighbors or the caretaker.
Store digital files in multiple locations, such as cloud and external drive.

Forms, deadlines and court steps

There is no nationwide standard form for a defect notice; the notice can be informal but should be documented in writing. For court claims, the Civil Procedure Code (ZPO) applies and local courts (Amtsgericht) are usually competent for tenancy disputes.[2] For key legal questions and precedents, Federal Court of Justice case law is relevant.[3]

The local court is usually the first instance for tenancy disputes.

Key takeaways

  • Document promptly and systematically.
  • Send a written defect notice and keep proof of dispatch.
  • Inform your insurer early and clarify coverage.
