When a former Swiss landlord says rent is unpaid and keeps a deposit, first separate three things: the rent ledger, any ancillary-cost statement, and the legal form in which the deposit is held. A tenant’s bank statements can help show payments, but only when each transfer is matched to the right month, amount, recipient, and contractual obligation. A deposit is not automatically available to settle every disagreement, and the rules for a bank-held tenant security are not necessarily the rules for a guarantee or an ordinary transfer.
The Swiss Code of Obligations (CO), Articles 257a to 257e, in the official Fedlex text marked in force as of 1 October 2026, provides the starting point. Article 257a says ancillary costs are payable only if specially agreed. For residential and commercial premises, Article 257b describes them as actual costs for services connected with use and requires the landlord to allow inspection of supporting receipts on request. Article 257e sets specific rules for monetary or securities security, including an account in the tenant’s name, a residential cap, and conditions for bank release.
This is a records and process guide, not a conclusion that any particular landlord owes a refund. The original question was from someone who identified as a student in Switzerland, described multiple roommates, and said the landlord claimed unpaid rent while the tenants had bank proof. For a shared lease, identify who signed, who paid, whose name appears on the deposit account, and which tenant is making the request. Those distinctions can change the documents and the next step.
Build a month-by-month rent ledger
Do not send a bundle of unlabeled bank statements and expect the recipient to reconstruct the rent history. Start with a table that connects the amount due to the payment made:
| Rent period | Amount due under lease | Amount and date paid | Recipient / reference | Open question |
|---|---|---|---|---|
| Month 1 | Contract amount | Transfer date and amount | Name/account and reference | Does it match the landlord’s ledger? |
| Month 2 | Contract amount | Transfer date and amount | Name/account and reference | Was any roommate share paid separately? |
| Final month | Prorated or full amount only if applicable | Transfer date and amount | Name/account and reference | What does the lease say about the end date? |
This table is a working summary. Keep the original bank statement and lease in the same evidence folder. A transfer description may be blank or abbreviated; use the contract, payment reference, email confirmation, and recipient details to show why you believe it relates to a specific rent period.
For roommates, add a separate column for the person who initiated the transfer and for whose share it was sent. If one person paid the landlord on behalf of all tenants, preserve the internal records that explain the split. Avoid stating that “all rent was paid” if the bank evidence proves only one roommate’s part. Ask the landlord to identify the specific month, amount, and account entry that it says remains unpaid.
Separate base rent from ancillary costs. The lease may show a monthly advance payment for utilities or other costs; a later annual statement can reconcile those advances with actual eligible costs. Under CO Article 257b, a tenant may request inspection of supporting receipts for ancillary costs in residential and commercial premises. Ask for the statement period, allocation method, prior advances credited, and supporting receipts. Do not assume every electricity or maintenance amount is an ancillary cost simply because the landlord labels it that way.
Identify what kind of deposit you paid
A deposit arrangement can look similar in everyday speech while using different legal and banking structures. Check the lease, payment instruction, account name, and bank confirmation.
| Arrangement | What to verify | Why the distinction matters |
|---|---|---|
| Monetary security placed in a tenant-named bank account | Account holder, blocked status, bank, amount, and release conditions | CO Article 257e specifically addresses this kind of security |
| Securities deposited as security | Asset, bank custody, tenant name, and value | Article 257e also addresses securities, subject to the statute |
| Guarantee or insurance product | Provider, guarantee certificate, fee, parties and expiry | A guarantee is not the same as cash held in a tenant-named bank deposit account |
| Ordinary transfer to landlord or another recipient | Contractual purpose, recipient, amount, confirmation, and whether the parties intended statutory security | Do not assume the statutory bank-release procedure governs an ordinary transfer |
Article 257e(1) requires a landlord who receives monetary or securities security for residential or commercial premises to deposit it at a bank in a savings or deposit account in the tenant’s name. For residential premises, Article 257e(2) limits the security to three months’ rent. The provisions are important, but first establish whether the arrangement in your documents is actually the kind of security covered by the article.
Ask the bank or landlord for the account confirmation if you cannot tell from your paperwork. Record the account holder, institution, account or deposit reference, and the names of the tenants whose funds are held. Do not send a new request to an account or person copied from a forum comment. Verify recipient details through the original lease or a trusted official contact channel.
Understand the one-year rule without treating it as automatic release
Under Article 257e(3), the bank may release the security only with both parties’ consent or based on an enforceable payment order or final court judgment. The article also says that if the landlord has not legally asserted a claim against the tenant within one year after the tenancy ends, the tenant may request repayment from the bank.
That wording is narrower than “the bank will automatically return the money after one year.” The tenant must contact the bank and use its process. The tenant must also confirm that the tenancy ended on the date they believe it did, that the account is the statutory tenant-named deposit, and that the landlord has not taken a legally relevant step within the period. A landlord’s silence or a vague email is not enough to determine those points. Nor should a tenant ignore a formal claim or notice because the one-year date is approaching. The Federal Office of Housing’s current overview of Swiss tenancy law, published in August 2026, describes the federal framework and the specific role of cantonal supplements under Article 257e(4); it does not replace checking the applicable canton’s procedure.
Write down the tenancy end date and calculate the one-year date separately. Keep the handover record, move-out confirmation, final rent statement, and bank details. If the landlord says it has asserted a claim, ask for the document, date, forum, amount, and tenant against whom it was brought. Do not try to decide from a generic message whether the statutory condition is satisfied; the bank and a qualified local adviser can help interpret the actual records.
The CO allows cantons to issue supplementary provisions. Procedure and the competent authority are local. The Federal Office of Housing’s overview of tenancy conciliation explains that a conciliation attempt precedes adjudicative proceedings for civil disputes in residential and commercial tenancy. Find the relevant canton authority and current filing instructions rather than relying on another canton’s form or deadline.
Ask for an itemized reconciliation
Once you have the core records, send a focused request. Identify the lease, property, tenants, move-out date, and deposit arrangement. Attach a payment ledger and point to the disputed months without editing the original statements. Ask the landlord to provide:
- its month-by-month rent ledger and the exact claimed balance;
- the payment date, amount, and reference it believes is missing;
- the final ancillary-cost statement, the period covered, and advances credited;
- copies or inspection details for supporting receipts where applicable;
- the deposit account or guarantee information and the amount held;
- the steps and documents it says are required for release.
Set a reasonable response date, but do not invent a statutory response deadline where none has been verified. Use a delivery channel that keeps a copy and proof of sending. If the landlord replies by phone, summarize the conversation in writing and invite corrections.
A neutral message might say: “I am reconciling the final account for [property] and the tenancy that ended on [date]. My ledger shows payments for [periods] and a deposit of [amount] through [verified channel]. Please identify each amount you say remains due, provide the rent and ancillary-cost statements with supporting records, and confirm how the deposit is held and what release procedure applies.”
Keep the request factual. Do not accuse the landlord of theft or threaten public exposure. A claim may be a genuine ledger error, an unresolved roommate allocation, a final utility statement, or a disagreement about the legal deposit form. The document trail helps separate those possibilities.
A fictional example: rent proof and a final electricity statement
Nina and two roommates rent a furnished flat in Lausanne. The lease lists all three tenants, one monthly rent amount, and an advance for ancillary costs. Each month, Nina transfers the full rent from her account after receiving the roommates’ shares. The landlord later claims that April was not paid and says it will deduct electricity from the deposit. Nina has bank statements showing an April transfer, but the reference field only says “rent.”
Nina makes a ledger for every rent month, attaches each transfer confirmation, and includes the roommates’ payment records as a separate supporting section. She asks the landlord to identify the April entry it thinks is missing and sends the utility statement request separately. The final account shows that the landlord had applied Nina’s April transfer to a different month. The electricity amount remains under discussion because the lease and statement need to be compared. Nina confirms whether the deposit is in a tenant-named bank account before asking the bank about release.
The example does not assume the electricity charge is valid or invalid, or that the deposit must be released. It demonstrates why rent and utility reconciliation should be separate and why custody of the deposit needs its own evidence.
Common mistakes to avoid
Treating the account form as a detail. A blocked deposit account, a guarantee, and a transfer to a landlord are not necessarily governed by the same release mechanism. Verify the documents first.
Using the one-year rule as an automatic deadline. Article 257e gives the tenant a right to request repayment from the bank under stated conditions. It does not say the bank will release funds without a request or that every arrangement is covered.
Sending unrelated statements without labels. Match every transfer to a period and recipient. Keep roommate contributions separate from the landlord payment.
Accepting an unsupported utility deduction. Ask for the lease term, statement period, actual cost, allocation, and credit for advances. Article 257b provides an inspection right for supporting ancillary-cost receipts.
Withholding rent to force a deposit refund. The deposit dispute and rent obligation are different issues. Do not offset, withhold or redirect payments without advice specific to your lease and canton.
Using another canton’s process. The Federal Office of Housing identifies local conciliation authorities. Confirm the competent office, procedure, language, service method and deadline locally.
Checklist before you ask for release
- Identify every named tenant and the party to the lease.
- Record the move-out and contract-end date from written evidence.
- Build a month-by-month rent ledger with payment dates, references and recipients.

Questions about rental deposits in Switzerland
Must a Swiss landlord place a cash rental deposit in a tenant's name?
For statutory monetary or securities security for residential or commercial premises, Code of Obligations Article 257e says the landlord must deposit it at a bank in a savings or deposit account in the tenant's name. A guarantee or bond may be a different arrangement.
Does the one-year rule automatically release a Swiss deposit?
No. Article 257e says that if the landlord has not legally asserted a claim against the tenant within one year after the tenancy ends, the tenant may request repayment from the bank. It is not automatic bank release and does not fit every deposit arrangement.
Can a landlord charge electricity costs from the deposit?
Check the lease and the actual statement. Articles 257a-b address agreed ancillary costs, actual costs in residential and commercial premises, and inspection of supporting receipts on request. The specific bill and contract matter.
What if the landlord says rent was missed but I have bank statements?
Create a month-by-month ledger and match each statement to the lease, payment reference, account recipient and rent period. Keep any disputed month separate and ask for the landlord's itemized calculation.
Where can a tenant take a Swiss rental dispute?
The Federal Office of Housing describes a conciliation attempt before adjudicative proceedings for civil tenancy disputes. The competent authority and procedure depend on the canton and claim.
What if my deposit was transferred to the landlord's ordinary account?
First verify the account, contract, and whether the arrangement was statutory security, a guarantee, or another payment. Do not assume Article 257e's bank-release mechanism applies to an ordinary transfer.
This is general information about Swiss residential tenancy records, not legal advice. Deposit arrangements, utility charges and procedure can depend on the contract and canton. Check current official rules and consult a qualified local professional about a live dispute.
