A rental deposit works best when the agreement, payment instructions and account records tell the same story. This guide explains how to prepare the arrangement, track instalments and keep the tenant’s security separate throughout a residential tenancy in Germany.
Planning to let a property in Düsseldorf or NRW? Discuss your letting
Start with the security actually agreed in the tenancy
A deposit can become an afterthought when everyone is concentrating on signing the lease and arranging the handover. Give it a separate place in your preparation. Read the agreement before requesting money: does it require security, what amount does it specify, and in what form? Section 551 of the German Civil Code, known as the BGB, limits an agreed security arrangement. It does not itself replace a missing contractual agreement to provide a deposit.
This guide concerns ordinary residential lettings in Germany, including properties in Düsseldorf and elsewhere in North Rhine-Westphalia. Its rules do not change because the landlord or tenant reads them in English. In German paperwork, Barkaution means a monetary deposit; payment by bank transfer can qualify. The word does not require the tenant to arrive with banknotes. A guarantee is a different form of security and should not be recorded as though money had already reached an account.
Record the agreed amount, payment arrangement and person responsible for administering it. If several people own the flat, decide who will arrange the account and answer questions. If a property manager is involved, establish the capacity in which that manager acts and where the money will be held. A general statement that the manager handles deposits leaves important practical details unresolved.
Check that the lease, payment instructions and handover paperwork are consistent. Two different account numbers or a demand for the full amount alongside an instalment clause create avoidable uncertainty. A clear arrangement made before the first transfer gives both parties a workable starting point and reduces the need to reconstruct intentions later.
Calculate the limit using the correct rent figure
Under section 551(1) BGB, the usual residential security limit is three months’ rent excluding operating costs identified as a flat charge or advance payment. In a conventional German lease, the relevant figure is the Nettokaltmiete: the basic rent without those additional charges. The total monthly bank transfer is therefore not necessarily the figure you should multiply by three.
Consider a flat in Düsseldorf with basic rent of €900 and an operating cost advance of €250. The tenant pays €1,150 each month, but the maximum agreed deposit in this example is €2,700. Multiplying the full monthly transfer would produce €3,450, which is the wrong basis for the deposit. The parties can agree a smaller amount; the statutory ceiling is not an instruction to demand the maximum in every tenancy.
Keep this calculation separate from the economics of letting the property. A deposit is not another rent payment or a fund for refurbishment, mortgage payments or owners’ association charges. If you need the deposit to cover those expenses, revisit your own cash planning. The guide to calculating the rent addresses the underlying rental figure; holding someone else’s security serves a different purpose.
Do not casually add further compulsory security after already requiring the full ordinary deposit. Particular guarantee arrangements need their own legal assessment. Likewise, a later rent increase should not automatically generate a new deposit invoice without checking the contractual basis. For an uncomplicated start, retain a short calculation showing the basic rent, the agreed multiplier and the resulting deposit, alongside the relevant lease clause.
Build the three instalments into your payment process
Where security is to be provided as money, the tenant may pay in three equal monthly instalments. The first falls due at the beginning of the tenancy. The second and third fall due with the immediately following rent payments. These are the rules in section 551(2) and (4) BGB. A lease term cannot remove them to the tenant’s disadvantage by making the full deposit compulsory before the keys are handed over.
If the example tenancy begins on 1 October, the €2,700 deposit can be paid as three instalments of €900: at the start, then alongside the following rent payments for November and December. Ordinary rent remains a separate obligation. Give clear payment references so that an incoming €900 does not accidentally become a partly paid rent entry or a record of the whole deposit being complete.
Use a simple schedule containing the total agreed security, the instalment due, the amount actually received and the remaining unpaid balance. After the first payment, it should show €900 received and €1,800 still to come. That remaining €1,800 is not automatically overdue at that point. Comparing the full contractual deposit with the account balance without considering due dates can produce unjustified reminders.
The first instalment should follow the intended separate account arrangement, just like the later payments. Do not postpone opening the account until all three instalments have arrived. If a payment appears missing, first check the due date, bank details and payment reference. Any proposed legal action over deposit arrears requires an assessment of the actual situation. The guide to paying the rental deposit in instalments explains the payment framework in more detail.
Choose an account that provides genuine separation
For money entrusted to the landlord as security, section 551(3) BGB provides the default: placement with a credit institution at the interest rate customary for savings deposits with three months’ notice. The parties may agree another form of investment. In either case, the deposit must remain separate from the landlord’s assets. A more attractive advertised return does not remove that requirement or replace an agreement on a different investment arrangement.
Tell the bank explicitly that the funds are a residential tenancy deposit held for someone else. Ask how the account identifies that status and which documents demonstrate the separation. Merely opening another ordinary private account and naming it “deposit” in your spreadsheet is not enough. The arrangement needs to address the legal separation, rather than just making your own bookkeeping easier.
Another possible structure is an account opened by the tenant and pledged to the landlord as security. Here, the agreement, effective pledge and bank confirmation must fit together. A statement showing that the tenant has savings is not proof that those savings have been pledged. In its judgment of 13 October 2010, VIII ZR 98/10, the German Federal Court of Justice also confirmed that a tenant may make payment to the landlord conditional on being given an insolvency-protected account.
Before choosing the arrangement, ask about opening documents, administration, charges and eventual release. Resolve who must bear any charges instead of simply deducting them from the security. The account should be understandable to both parties and capable of being handed over or closed with a clear documentary trail.
Keep evidence of the agreement, payment and actual placement
Your deposit file should answer three separate questions: what was promised, what was received and where is it now? A signed lease answers the first. A transfer confirmation shows a movement of money, but may not show that the money was subsequently placed in a properly separated account. Account documentation and statements complete the picture. Treat them as complementary evidence rather than interchangeable pieces of paper.
Create a clearly identified file for each tenancy. Keep the deposit clause, account information, records of each instalment, interest entries and later changes together. Identify the property by its address and position within the building. A tenant’s name alone may be ambiguous when there are several flats, joint tenants or successive agreements involving the same person.
A payment acknowledgement should state exactly what arrived. After the first payment in the example, it can confirm receipt of €900 as the first deposit instalment for the identified tenancy, against an agreed total of €2,700. Avoid saying that the deposit has been paid in full. If cash is exceptionally accepted, issue a receipt showing the amount, date, recipient and purpose, and also document the subsequent separate placement.
When providing evidence to the tenant, show the relevant allocation and account arrangement without disclosing other people’s transactions. An unfiltered statement covering several tenants is a poor way to answer an individual request. Keep access to the file limited to people who need it for the task. A useful summary makes the records easier to follow, but does not replace the bank’s underlying documents or resolve a missing payment by itself.
Reconcile interest and changes throughout the tenancy
Receiving the final instalment does not end the need to administer the deposit. Under section 551(3) BGB, returns belong to the tenant and increase the security. Allocate them to the relevant deposit balance. The initial ceiling of three basic monthly rents does not stop the balance growing through interest; that growth is different from demanding an additional contribution from the tenant.
For illustration, suppose €18 of interest is credited after the full €2,700 has been paid. With no other entries, the balance would be €2,718. The €18 is an invented arithmetic example, not a current bank rate or a promised annual return. In the real file, use the actual statement and consider any other entries separately. Do not replace a missing statement with an assumed interest percentage.
A periodic check can be included in your annual review of property documents. Compare the agreed security with received instalments, check the actual balance and identify any account changes. This is a suggested administrative routine, not a claim that the law imposes a particular annual reporting deadline here. The statutory exception to paying interest on accommodation in student or youth residences does not arise simply because an ordinary flat happens to be let to students.
If you change banks, retain the closing balance, transfer evidence and documents for the replacement arrangement. Establish the destination before closing the old account. If you discover that deposit money was mixed with your own funds, correct the arrangement promptly and transparently. The consequences of the earlier handling, including any missing returns, need assessment on the facts. A later transfer does not automatically erase what happened before it.
Keep disputed claims separate from the security balance
A landlord who disagrees with a rent reduction may be tempted to fill the gap from the deposit. During an ongoing residential tenancy, the deposit cannot be realised to satisfy disputed claims. The Federal Court of Justice confirmed this in VIII ZR 234/13, decided on 7 May 2014. The additional contractual provision used in that case did not permit the landlord to override the tenant’s protection.
Suppose the tenant pays €200 less because of an alleged defect, and you believe the reduction is unjustified. Moving €200 from the deposit account into your rental income account does not settle that disagreement. Keep the defect notification, payment history, your inspection findings and correspondence. Assess the existence and enforceability of the claim separately from the duty to hold the deposit properly.
Even where a claim is undisputed or established by a final judgment, check the security agreement and the circumstances before using the funds. A bank’s technical withdrawal procedure does not determine whether you have the necessary substantive entitlement against the tenant. The fact that an account permits a transaction is not a substitute for that assessment.
Keep repair records and claims correspondence in the tenancy file, while recording any actual deposit movements clearly in the deposit account history. This makes later advice and accounting easier. The judgment described above concerns use during the ongoing tenancy. It should not be presented as a complete answer to settlement after the tenancy ends, when the remaining claims and the appropriate treatment of the security require their own examination.
Prepare for a change of manager, a sale or the next letting
A deposit arrangement should remain understandable when the person who set it up leaves. On a change of property manager, hand over the actual balance, account evidence, instalment record, returns and any unresolved allocation questions. Clarify who can communicate with the bank and who will answer the tenant. A list of original contractual amounts is insufficient if payments or interest entries are missing.
If a let residential property is sold, section 566a BGB provides for the purchaser to enter the rights and obligations arising from the security. If the tenant cannot obtain it from the purchaser at the end of the tenancy, the previous landlord remains obliged to return it. An internal transfer arrangement therefore does not justify a blanket statement that the seller has no further responsibility. Coordinate the transfer and supporting documents with the relevant legal professionals.
For a forthcoming letting, bring the practical decisions together: the lawful agreed amount, the account arrangement and the person checking the three receipts. These decisions sit alongside rent setting, tenancy preparation and selecting an appropriate tenant. The guide to finding a tenant helps place those earlier stages in context.
Use the landlord enquiry form to tell RICHTER Immobilien-Transaktionen the location, property type, intended tenancy start and your current preparation stage. That creates a useful basis for discussing the letting. Ask the bank about account operation and pledges, and a lawyer practising German tenancy law about disputed claims or unusual contractual arrangements. Full bank statements and online banking credentials are not needed for an initial property enquiry.
