This helps you as a tenant or student in Germany decide which protection makes sense. At the end you will find practical examples and references to official forms.

Which damages do liability and household contents insurance cover?

Generally: private liability insurance covers damage you cause to others' property; household contents insurance protects movable items in your flat. For tenants this means that compensation claims a landlord may make for damage to the rental property are anchored in tenancy law.[1]

  • Lock replacement: exchanging the door lock if there is danger to third parties.
  • Locksmith and emergency costs: costs for changing locks or emergency opening may apply.
  • Damage to locking systems: repairs or system replacements depending on cause and coverage.
  • Documentation: photos, receipts and notifications to insurer and landlord secure claims.
In most regions, liability insurance pays for the loss of keys belonging to others.

What should tenants do immediately?

Act promptly: notify the landlord, check your insurance contracts and collect receipts. Clarify whether you are solely responsible or a third party is affected (for example, a shared flat key).

  • Inform the landlord: report briefly in writing and describe the damage.
  • Contact a locksmith: obtain a cost estimate if it is an emergency.
  • Collect evidence: receipts, photos and exact times.
  • Check insurance: inform liability or household contents insurer and clarify any deductible.
Report the loss to your liability insurer immediately by phone and in writing.

Forms, proofs and legal steps

For larger damage or disputes it may be necessary to prepare official forms, damage reports or even legal action. Information on procedural steps is available in the Code of Civil Procedure.[2] Templates and guidance on official forms are available from the Federal Ministry of Justice.[3]

If a landlord refuses payment or a possession claim is threatened, local courts (Amtsgerichte) are competent in the first instance; more complex legal issues can reach the Federal Court of Justice.[4]

Respond to letters from the landlord or court deadlines within the stated timeframes to preserve your rights.
