BGH rulings: pros & cons in practice

BGH decisions often clarify how tenancy law rules apply in practice. For tenants, rulings on rent reduction, service charge statements or termination are particularly important. When reading a judgment it helps to isolate the concrete legal issue and check whether the facts of your case match. Financial consequences, burden of proof and deadlines are central aspects you should document.[1]

Keep correspondence and photos stored in chronological order.

Practical pro-and-con checklist

  • Check documentation (document): photos, emails, witnesses recorded.
  • Assess repair needs (repair): describe urgency and effects on habitability.
  • Weigh cost impacts (rent): consider rent reduction or compensation.
  • Identify court risks (court): litigation costs, duration and chances of success.

If you live in a shared flat, collect separate evidence for each roommate and a joint list of damages; this helps the local court evaluate. For complex cases prepare complete documents early: tenancy contract, handover record, service charge statements and correspondence with the landlord.

Separate receipts per flatmate improve the chance of success in disputes.

What to do for termination, rent reduction or repair disputes

In case of termination, significant defect notice or a justified rent reduction you should act in a structured way: check deadlines, send a formal defect notice or a written termination and document all steps. If court clarification is needed, the local court is usually competent; procedural rules of the ZPO may be relevant.[2]

Important forms and templates

  • Termination letter (template): short form for timely terminations; example: ending tenancy due to move or uninhabitability.
  • Defect notice (form): written request for repair with deadline; example: report heating failure by email and registered mail.
  • Evidence folder (document): collect photos, witness list, records and invoices.

Many courts do not require special templates, but a clear dated and signed statement often replaces a form. For eviction suits or complex claims observe ZPO deadlines and consider legal assistance.[3]

FAQ

When can I reduce the rent?
You can reduce rent if habitability is significantly impaired; the percentage depends on the individual case and should be documented.
What deadlines apply after termination?
For ordinary termination the statutory notice periods of the BGB apply; for extraordinary termination it depends on the specific reason.
Which court is competent?
Most tenancy disputes are handled by the local court; appeals go to the regional court, and fundamental questions can be decided by the BGH.
