Avoid Tenant Mistakes: Tenant Unions in Germany

Tenant Associations & Advice Services 3 min read · published September 07, 2025

Many tenants in Germany do not know how to use tenant unions effectively when it comes to tenant rights, rent increases, rent reductions or repairs. This practical guide explains clearly which typical mistakes often occur — from missing documentation to missed deadlines — and how to avoid them. You will learn which official forms are important, when you should contact the local court or seek advice, and how to document damage, heating problems or unlawful terminations properly. The text shows simple steps and examples so tenants can enforce their rights without immediately needing a lawyer, and it refers to relevant sections of the BGB[1] and responsible authorities in Germany.

Common Mistakes

Many problems arise from formal errors or missing evidence. The most common mistakes can often be avoided with simple measures.

  • Check deadlines (deadline): Do not miss response periods for defect reports and objections.
  • Missing documentation (record): No photos, no dates, or no witness statements about defects.
  • Not reporting defects (repair): Reporting defects too late or only orally instead of in writing.
  • Incorrectly completed forms (form): Submitting forms or template letters incomplete or without evidence.
Document defects immediately with photos and dates.

How to Use Tenant Unions Effectively

Tenant unions offer advice, template letters and often an initial legal review. Use these services deliberately: bring clear documentation, ask for concrete template letters and clarify whether the union's advice includes further representation.

  • Membership fee (fee): Check costs, contributions and scope of services before joining.
  • Request advice (contact): Arrange a consultation and bring all documents.
  • Use template letters (form): Use templates for defect notifications, rent reductions or objections.
Membership often provides quick access to template letters.

Important Deadlines and Forms

Deadlines and the correct forms are crucial. Here are some central forms and how to use them practically.

  • Termination letter (tenant termination, template): Use a clear termination letter with date and signature; example: "I hereby terminate the tenancy as of 30/06." Consider sending by registered mail.
  • Defect notification (in writing): Describe the defect, location, date, impact and request a deadline for remediation; attach photos.
  • Eviction suit / complaint (for enforcement): If a landlord proceeds legally or you must assert rights in court, prepare documentation about the housing situation; procedural rules follow the ZPO[2].
  • Certificate of eligibility for social housing (WBS) – if relevant: Apply for the WBS at your competent authority when you need income-restricted housing.

For court actions, the local court (Amtsgericht) is the first instance for tenancy disputes[3]. Observe the Civil Procedure Code for deadlines and formal requirements[2].

Submit documents on time and completely to avoid disadvantages.
