For germany landlord not returning, the strongest first move is usually a clear file. Caira can help build it from uploads. Ask about Germany law, draft letters or forms, and upload files for review.

If your German landlord has not returned your Mietkaution, start by collecting and organising your evidence—instead of arguing about a fixed refund deadline. The official materials back up the basics of deposit law using BGB sources. They cover the deposit framework and operating-cost context. Importantly, they also warn that refund timing is not as simple as a single statutory date. As a result, this article avoids giving hard claims, such as the landlord must pay after exactly three or six months.
The safer approach is to ask what is being withheld, why, and what evidence supports that.
Build the deposit file
Gather everything into one folder. Include the Mietvertrag, Kautionszahlung proof, bank transfer, deposit receipt, move-in Übergabeprotokoll, move-out Übergabeprotokoll, photos, key-return proof, final rent payments, utility or Nebenkosten records, and all correspondence with the landlord or Hausverwaltung. Paid by cash? Collect every receipt, witness note, email, or even a later message confirming the payment.
If several tenants or flatmates contributed to the deposit, keep track. Record who paid which amount and clarify whose bank account should receive the refund.
Shared flats and sublets
Living in a WG, sublet, or joint tenancy? Clarify who you’re actually dealing with. Main tenant, subtenant, co-tenant, landlord, and property manager all have different roles. Maintain separate files for the Hauptmietvertrag, Untermietvertrag, transfer confirmations, and chat records. This way, you avoid demanding money from the wrong party.
Ask what is actually being withheld
Push for clear answers—don’t let the landlord stay vague. A deposit may be held back for alleged damage, unpaid rent, missing keys, cleaning, renovation, outstanding service charges, or expected Nebenkosten. Find out if the full deposit is at stake or just a portion. Then, request a detailed Abrechnung and the supporting Belege.
If only part of the deposit is disputed, ask for the rest back now. This keeps your conversation focused, so one issue doesn’t turn into a much larger argument.
Be careful with timing statements
Many online discussions mention three to six months. However, official guidance cautions against presenting that as a simple statutory deadline without legal-source support. Landlords may need some time to check potential claims, but unexplained refusals are not acceptable. Your message should clearly ask for status, calculation, evidence, and the return of any undisputed funds.
If the landlord says Nebenkosten are pending, dig deeper. Ask which accounting period is involved, and how it justifies the withheld amount.
If the landlord claims damage
Compare move-in and move-out records side by side. If damage already existed, point to the specific photo or protocol entry. Should the landlord claim repair costs, insist on invoices, estimates, photos, and an explanation of how the figure was calculated.
If cleaning or Schönheitsreparaturen are raised, keep those clauses and evidence apart from your deposit request. Don't accept any deduction just because a cost category is mentioned. Ask for substantiation.
If Nebenkosten are the reason
Sometimes, landlords withhold deposits pending operating-cost settlement. Keep this separate from damage claims. Request the expected Nebenkostenabrechnung, the approximate amount being reserved, and ask if the balance can be refunded now. When the Abrechnung arrives, check the lease, billing period, allocation keys, earlier payments, and any Belegeinsicht options.
This article doesn’t decide whether a particular holdback is lawful; it aims to help you request concrete explanations.

Escalate with a clean record
If you get no response from the landlord or property manager, send a dated follow-up and keep delivery proof—always.
Before using stronger legal language, seek help. A tenant association, legal insurer, Caira, or an advice centre can review the lease, handover protocols, and local court risks. Make no threats you can’t back up.
A concise, organised file—with the contract, deposit proof, handover records, photos, and landlord’s calculation—will help more than a long, emotional message.
Where Unwildered fits
Upload your Mietvertrag, deposit transfer, Übergabeprotokolle, photos, Nebenkosten documents, and any landlord replies. Unwildered can spot which deductions require evidence, draft a German follow-up, and help build a document pack for advice.
