Tenants: Documents & Deadlines in Germany

Modernization & Cost Allocation 3 min read · published September 07, 2025

As a tenant in Germany you should know which documents and deadlines are relevant for photovoltaic (PV) and tenant electricity, especially for modernization measures and cost allocation. This text explains step by step practical actions: which forms to use, how to calculate deadlines and which proofs are useful. I show examples for termination or objection deadlines, the role of service charge statements and necessary documents for objections to cost allocations. The aim is for you to meet deadlines reliably, understand your rights vis-à-vis the landlord and avoid formal mistakes. The information refers to German tenancy law and is in plain language so you can react quickly. At the end you will find sample texts and references.

Which documents do tenants need?

Before you respond, collect all relevant documents. Complete files make objections, rent reductions or, if necessary, a lawsuit easier.

  • Rental agreement (current and previous versions).
  • ID card or registration certificate.
  • Latest service charge statement and payment receipts.
  • Correspondence with the landlord (emails, letters).
  • Quotes, invoices and statements for PV or modernization measures.
Detailed documentation increases your chances of success.

Important deadlines and forms

Important provisions on the tenancy are regulated in the BGB, especially §§ 535–580a on rent and modernization[1]. For court actions the Code of Civil Procedure (ZPO) applies[3], and jurisdiction and procedures are usually handled by the local court as the first instance[2]. In disputes, decisions of the Federal Court of Justice (BGH) can be decisive[4].

Respond within statutory deadlines or you may lose rights.

Common deadlines (examples)

  • Notification of defects: as soon as possible, preferably within a few days after discovery.
  • Objection to service charge statement: check the billing period and act promptly.
  • Eviction claim: deadlines depend on filing the claim at the competent local court[2].

Forms and templates (when to use)

For many steps there is no mandatory uniform form, but standardized sample texts exist, e.g. termination or objection letters. A termination letter to the landlord should always be in writing and state the reasons for termination. An objection to a cost allocation should include date, exact items of the statement and copies of supporting documents.

  • Termination letter (sample): use for ordinary or extraordinary terminations with deadline indication.
  • Objection letter against service charges or cost allocations: send by registered mail and keep proof of receipt.
  • Filing a lawsuit at the local court: if out-of-court steps fail, the local court accepts the claim.

Example: Objection to cost allocation for PV

Suppose your landlord announces allocation of modernization costs to tenants (e.g. installation of a PV system). Check the announcement for mandatory information and deadlines. Request supporting documents, calculate which cost shares affect you, and send a written objection with reasons and copies of relevant documents within a reasonable deadline.

  • Step 1: Check the announcement and note the deadline.
  • Step 2: Request documents (invoices, contracts, financing evidence).
  • Step 3: Submit objection in writing and document receipt.
  • Step 4: Consider legal advice or court action at the local court if no agreement is reached[2].
