Tenant rights & basic protections (MRG) 2 min read · published September 10, 2025
Many tenants in Austria face the question of whether they can claim back overpaid subrent. This guide explains clearly which rights tenants have, which documents are important and which deadlines to observe. We describe how to document payments, which steps are useful when talking to the main tenant and when legal action before the district court may become necessary. Practical tips show how to assert claims in writing and which documents help in proceedings. The information is based on tenancy law in Austria[1] and is aimed at tenants seeking a fair solution for overpaid subrent.

When can tenants claim back overpaid subrent?

A claim is possible if it can be proven that more was paid than agreed or than is customary. It is important whether a valid sublease exists, which agreements are documented in writing and whether the amount of the subrent violates mandatory tenancy law. In many cases, an initial written demand to the main tenant is recommended.

In many cases, a written demand is the first necessary step.

What should you document?

  • Gather documents: Copies of all lease agreements, sublease agreements and all payment receipts.
  • Prove overpayments: bank statements, receipts and payment confirmations.
  • Photos and communication: photos of the apartment condition and emails, chats or SMS as evidence.
Documentation increases your chances of success in court.

How do you demand repayment?

Start with a clear written demand that states the overpaid amount, the supporting documents and a reasonable deadline. Use registered mail or an email with read receipt and keep copies. Keep a log of conversations and responses; often an amicable agreement is possible before legal steps are necessary.

Set clear deadlines and keep a copy of the demand.
  • Send written demand: Ask the main tenant to repay and state a deadline.
  • Set a deadline: Provide a reasonable deadline (e.g. 14 days) and indicate possible next steps.
  • If no payment is made, consider filing a claim at the district court[2].

What happens in court?

In court the burden of proof matters: present contracts, payment proofs and your written demands. The district court reviews the claims and decides whether repayment is due. Smaller monetary claims are usually handled quickly; in more complex cases a lawyer or tenant organization can help.
