Notifying Changes: Tenant Rights in Germany

Housing Allowance & Rent Subsidies 3 min read · published September 07, 2025

As a tenant in Germany, changes occur in everyday life: flatmates move in or out, income changes, housing benefit applications are updated or important contact details need to be resent. This practical guide explains clearly which changes you should notify to your landlord or the authority, which deadlines apply and which official forms you can use. I explain examples for housing benefit and shared-flat situations, show how to send notifications digitally and legally effective, and name the responsible courts and laws so you can assess your rights with confidence. The information refers to current regulations in Germany and contains notes on evidence, template letters and the correct procedure in disputes.

When must tenants notify changes?

Under the rules of tenancy law (BGB), tenants and landlords have certain notification and duty-of-care obligations.[1] Not every change requires a formal notification, but many changes affect rent payments, insurance coverage or benefit entitlements (e.g. housing benefit).

  • Flatmates move in or out: inform the landlord and property management.
  • Income or payments change (housing benefit, rent subsidy): notify the competent authority.
  • Update bank details or payment method for rent payments.
  • Notify changes to access rules, key handover or contact address.
  • Report damage to heating, water or mold so repairs can be initiated.
In many regions tenants are entitled to basic habitability standards.

How do I notify changes digitally?

Many landlords and authorities accept e-mails, online portals or uploaded forms as proof. Make sure to obtain a confirmation of receipt or send the message by registered mail/electronic receipt so later proof is possible. State the date, type of change, relevant amounts and attach documents such as pay slips or bank statements. For housing benefit changes use the official guidance and forms provided by the Federal Government and the responsible local authority.[3]

Detailed documentation increases your chances in disputes.

Formal requirements and deadlines

Many notifications must be made "without delay"; in practice this means: as soon as possible, usually within a few days to weeks depending on the matter. In case of impending termination or eviction suits, the deadlines of the Civil Procedure Code (ZPO) must be observed.[2]

Who decides in disputes?

In tenancy disputes, local courts (Amtsgerichte) are usually competent in the first instance; appeals go to regional courts (Landgerichte), and fundamental questions may reach the Federal Court of Justice (BGH).[4] Special procedural rules apply to eviction lawsuits; seek legal advice early when deadlines are set.

Respond quickly to court service documents; deadlines are binding.

Frequently Asked Questions

1. Do I have to notify my landlord of every change?
No, not every private change must be reported. Relevant changes are those that affect rent payment, the use of the dwelling or contractual obligations.
2. How quickly must I report income changes for housing benefit?
Changes must be reported without delay; if in doubt, inform the competent authority immediately to avoid reclaiming of benefits.[3]
3. What evidence is useful?
Copies of pay slips, bank statements, new tenancy agreements or written confirmations from flatmates help to prove changes.

How-To

  1. Collect documents: pay slips, bank statements, tenancy agreement and correspondence.
  2. Choose the correct form: for housing benefit use the official housing benefit application and update your details.[3]
  3. Write the notification: include date, name, exact change and attachments; send by e-mail with read receipt or via the online portal.
  4. Secure proof of receipt: save confirmations, take screenshots or keep registered mail receipts.
  5. In case of dispute: gather evidence and check deadlines; if necessary, initiate proceedings at the local court or seek legal advice.

Key Takeaways

  • Notify relevant changes without delay to avoid disadvantages.
  • Always secure proof of the notification and attachments.
  • Seek legal advice early and observe deadlines.
