Template Letter for Tenants: Form Requirement Austria

Rent & increases (reference rent, categories, form) 3 min read · published September 10, 2025

As a tenant in Austria you often need written templates when formal requirements, rent adjustments or communications with the landlord are pending. This guide explains when a notice must meet formal requirements, which deadlines apply and which details must not be missing in the template letter. It shows practical phrasing for terminations, defect notifications and consent declarations as well as notes on handover and documentation. You receive a checklist for evidence photos and delivery confirmations, tips for sending (registered mail, proof of delivery) and notes on legal consequences of defective letters. If necessary we provide short template texts that you can easily adapt. We also explain when consultation with the district court or legal representation is sensible and how to apply for extensions of deadlines.

What does "form requirement" mean?

Form requirement means that a communication must meet certain formal criteria, e.g. written form, signature or exact address. In tenancy matters, formal rules are regulated in the Tenancy Law (Mietrechtsgesetz) on RIS[1], which is why correct form is often decisive for enforceability of claims.

Form errors can affect deadlines and claims.

When is a notice formally correct?

A formally correct notice includes clear addressing, date, clear facts, demands or deadlines and a legible signature. Special rules apply to terminations, rent adjustments and consents.

  • Recipient: Specify the landlord's name and exact address.
  • Deadlines: State deadlines clearly and indicate a date.
  • Evidence: Attach photos, invoices and reports as proof.
  • Handover: Add proof of delivery or a confirmation of receipt if possible.
Respond in time, otherwise claims may lapse.

Template letters & text blocks

Below you find short template formulations that you can adapt to your situation. The formulations are deliberately concise so that you can quickly adopt the main points.

Defect notification

Suggested wording for a defect notification with all mandatory information.

  • Describe the defect specifically, stating location and date.
  • Demand: Set a deadline for rectification (e.g. 14 days) and specify desired measures.
  • Attach: Photos, invoices or reports as evidence.
Evidence and photos simplify later claims.

Sample termination text

For terminations observe statutory deadlines and written form requirements; add apartment details and handover date.

  • Information: Lease, address, desired termination date.
  • Deadline: Check contractual and statutory notice periods.

Evidence & dispatch

How to document and send notices correctly.

  • Documentation: Keep copies, photos and confirmations of receipt.
  • Dispatch: Use registered mail, proof of delivery or personal handover with receipt.
  • Contact: Inform the landlord by phone as well and note the conversation.
Registered mail often provides the best proof of delivery.

Frequently Asked Questions

Do I always need written proof?
Not always, but for formal requirements and imminent loss of deadlines we always recommend written notice and proof of delivery.

Send important letters by registered mail or hand them over against confirmation of receipt; document date and content.

  3. Draft: State a clear demand and an exact deadline.
