Security Deposits & Accounts 2 min read · published September 07, 2025
As a tenant in Germany, the security deposit with an index rent raises particular questions: How do calculations change, may the landlord offset interest or parts of the deposit, and what deadlines apply for repayment? This practical guide explains step by step how to check receipts, refute damage claims and reclaim the deposit securely. You will learn which sections of the BGB are relevant, when an informal letter is sufficient and when a lawsuit at the local court is necessary. There are sample phrases for the demand, notes on documenting the handover and tips for dealing with utility bills. If needed, we explain which official forms are required and how to start proceedings at the local court.

Deposit and Index Rent E289 Brief Explanation

Index rent means rent adjusts according to a price index. For the deposit, the rental and obligation law of the BGB generally applies [1], while the exact handling of offsets is typically decided by contract and on a case-by-case basis. With utility bill settlements, landlords may need time to calculate charges, which can delay payout.

In most cases, the BGB fundamentally protects tenants' rights.

What Tenants Should Watch

  • Check deadlines: Observe statutory and contractual deadlines for repayment.
  • Collect evidence: Secure rent payments, utility bills and the handover protocol.
  • Send a written demand: Set a deadline and request repayment of the deposit.
  • Review utility charges: Only proven claims may be offset.
  • If there is a dispute: Consider filing a lawsuit at the local court; procedural law (ZPO) governs the process [2].
Detailed documentation increases your chances in court.

Frequently Asked Questions

Does an index rent affect deposit repayment?
The index rent itself does not change the legal conditions for the deposit. The decisive factors are the contractual agreements and whether the landlord offsets legitimate claims.
How long does the landlord have to repay?
There is no fixed statutory deadline in the BGB, but repayment must occur within a reasonable time; utility bill settlements often take several months.
Does the landlord have to pay interest on the deposit?
Interest obligations arise from law and contract design; tenants are advised to keep records via a separate deposit account so interest is documented.
Which forms or steps are needed for a lawsuit?
For court action use the complaint form provided for your local court; many courts offer a template and filing instructions.

How-To

  1. Check receipts: Collect rent payments, deposit receipts and the handover protocol.
  2. Write an informal demand: Set a clear deadline (for example 14 days) and request repayment.
  3. Wait for a response: Document all answers and give the landlord reasonable time to review.
  4. Legal steps: If necessary, file a complaint at the local court using the prescribed complaint form [3].
Always respond in writing to claims so you have evidence.
