Tenants: Proving Interest Credits in Germany

Security Deposits & Accounts 3 min read · published September 07, 2025

Many tenants in Germany face the task of proving interest credits on the security deposit account — especially during ongoing court disputes in large cities. Success depends on careful documentation: bank statements, written confirmations from the property manager, and detailed payment logs. In proceedings before the local court clear evidence is often decisive because deadlines and formal requirements apply. This article shows step by step which documents tenants should collect, how to calculate interest correctly and which official authorities and laws are relevant. The guidance is practical, explained in plain language and tailored to the challenges in German urban areas so that you can reliably substantiate your claims. At the end you will find an FAQ, a short guide for submitting evidence to the court and links to official forms and rulings.

What tenants should watch now

If you want to prove interest credits on the security deposit, everything starts with the right documents. Collect all relevant statements early and request written confirmations so that clear proof is available in case of dispute.

Document every step with a date and a short description.
  • Collect bank statements (evidence): full monthly and annual statements of the deposit account.
  • Obtain written confirmation (form): inquire with the property manager or landlord which interest amounts were credited.
  • Prepare interest calculation (money): overview of rate, period and computed amounts.
  • Secure payment receipts (evidence): document all transfers and refunds.

Mention the deposit account in pleadings and attach bank statements as exhibits. If there are conflicting statements, a clear chronological presentation is helpful: dates of deposits, start of interest period and dates of credits.

A chronological overview increases the court's ability to follow your case.

Formal notes and deadlines

In civil disputes the rules of the BGB and the ZPO apply. Mention the relevant paragraphs in your filings and submit evidence in time so the local court can examine your claims[1][2].

Respond to mail from the court or landlord within the stated deadlines.

Which laws matter?

  • Civil Code (BGB) - tenancy law (e.g. duties to return the deposit and interest).
  • Civil Procedure Code (ZPO) - rules on evidence and deadlines in court.
  • Case law of the Federal Court of Justice (BGH) - important rulings on deposits and interest calculation[3].

In many large cities local courts review evidence strictly because caseloads are high. Therefore completeness matters more than quantity: prefer a few clearly explained documents over many unorganized proofs.

Practical proof: example procedure

An easy, traceable proof could look like this: 1) collect bank statements for the relevant period. 2) create a table with deposits, interest periods and calculated interest. 3) request a written confirmation from the property manager. 4) file the documents with the court as attachments and refer in your letter to the exact pages.
