Deposit Guarantee: Avoid Tenant Errors in Germany

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

Many tenants in Germany face uncertainties when it comes to deposit guarantees during ongoing proceedings. This text explains in a simple and practical way which typical mistakes occur in evaluation, accounting and documentation, how to use official forms correctly and which deadlines must be observed. I describe how you secure evidence, present deductions transparently and, in case of doubt, involve the competent local court or an advisory center. The aim is to give you, as a tenant, concrete steps so that you can protect your rights and avoid unnecessary costs. I also show which legal bases such as § 535 BGB are relevant and when an eviction lawsuit can influence the proceedings.

What is a deposit guarantee?

A deposit guarantee is a security for the rental deposit provided by a bank or insurance company in favor of the landlord. Instead of depositing money in a deposit account, a guarantor issues a guarantee document. For tenants this means lower liquidity burden, but special requirements for accounting and proof.

Typical mistakes and how to avoid them

  • Unclear accounting of the deposit: missing breakdown of claims and refunds.
  • Failure to meet deadlines: objection periods or statutory retention periods are missed.
  • Poor documentation: missing photos, handover protocols or invoices for repairs.
  • Forms not filled out correctly: missing signatures or unclear powers of attorney for representatives.
  • Misunderstanding judicial jurisdiction: filing in the wrong court instead of the competent local court.
Good evidence and clear accounts reduce disputes and speed up proceedings.

Practical steps during ongoing proceedings

When proceedings are ongoing, structured steps help: collect evidence, check claims, note deadlines and, if necessary, file objections in time.

  1. Collect all evidence: photos, invoices, handover protocols and correspondence.
  2. Request a detailed deposit accounting from the landlord and document receipt in writing.
  3. Check every deduction for justification and amount; request invoices for charged repairs.
  4. Observe deadlines for objections and filing a lawsuit and note dates in your calendar.
  5. If unsure, contact legal advice early or the local court to clarify jurisdiction.

Forms and official templates

Use official templates, e.g. the termination letter template of the Federal Ministry of Justice for legal letters or standard powers of attorney when representatives act. When requesting an accounting you can use a short informal letter in which you name a deadline and the requested documents.

Keep copies of all sent and received letters.
