As a tenant in Germany, single parents often ask how and when to report changes — such as new bank details, a move, or personal circumstances — to their landlord digitally. This article explains clearly which deadlines apply, which official forms matter, and how to document formal evidence. You will get an easy-to-use checklist, sample texts for emails and letters, and guidance on public authorities like housing allowance applications. The aim is to reduce uncertainty and protect rights without complicated legal terms. At the end you will find further links to official authorities and concrete next steps if you need written confirmation or court clarification.

What must tenants report?

Many changes affect the tenancy and should be reported to the landlord promptly[1]. These include:

  • Change of bank details for rent payments (e.g. new account information).
  • Moving within the building or moving out of the apartment.
  • Changes in household size that may affect housing allowance or rent subsidies.
  • Defects in heating, water or other areas that impair use.
  • Planned entries by contractors or viewings.
Detailed documentation increases your chances of success in disputes.

How to report digitally?

Digital reports are possible by email, via landlord portals or by upload to municipal portals. Choose a proof method (read receipt or registered mail) to prove delivery.

  • Email with read receipt and attached evidence.
  • Landlord or property management portal with document upload.
  • Registered mail for important legal changes.
Respond to read receipts and request written confirmation if necessary.

What to document?

Receipts and evidence are good practice: bank statements, the lease, emails, photos of damage and written confirmations from the landlord. Keep copies in chronological order.

Court jurisdiction and forms

Disputes over tenant rights in Germany are first heard at the local court (Amtsgericht); appeals go to the regional court and Federal Court of Justice decisions shape case law[3]. For housing allowance or funding applications, specific forms apply under the Housing Promotion Act (WoFG)[2].
