Sublease disputes and moving out: what mistakes should we avoid?
Swiss sublease disputes, move-out rules and deposit refunds – with concrete legal provisions, cantonal differences, from a Hungarian perspective.
What should you know before signing a lease?
Swiss tenancy law is governed primarily by the Code of Obligations (Obligationenrecht / OR, articles 253–274). This is a federal framework that cantons may supplement in certain areas — for example, in the organisation and procedure of tenancy conciliation authorities (Schlichtungsbehörde).
What should you pay attention to in the contract?
Rent and indexation. The contract must state the base rent (Nettomiete), the ancillary costs (Nebenkosten), and whether these are charged as a flat rate or based on actual accounting. In Switzerland, rent may be linked to changes in the reference interest rate (Referenzzinssatz) — if the rate falls, the tenant is entitled to request a rent reduction; if it rises, the landlord may initiate an increase. The reference interest rate is published quarterly by the Federal Housing Office (Bundesamt für Wohnungswesen / BWO).
Checking the initial rent. If the previous tenant paid a lower rent and your rent is significantly higher, you may challenge it before the tenancy conciliation authority within 30 days of moving in. If you miss this deadline, the right can no longer be enforced.
Security deposit (Mietzinskaution / Mietkaution). Under the law, the security deposit may be at most three months' net rent. The landlord must place it in a blocked bank account (Sperrkonto) opened in your name — they may not keep it in their own account. Check that the contract states the exact amount and the bank account details.
Ancillary rooms and common areas. Specify exactly what is included in the rental property: cellar, parking space, laundry room usage times. Anything not stated in the contract is difficult to prove later.
What are the most common causes of disputes?
The vast majority of Swiss tenancy disputes fall into three categories: withholding of the security deposit, allocation of maintenance obligations, and settlement of ancillary costs.
Withholding of the security deposit
The landlord may withhold the deposit only on the basis of actual, documented damage, and the withheld amount must be proportionate to the damage. Normal wear and tear (normaler Verschleiß / usure normale) — for example, faded paint or minor scratches on the floor — cannot be charged to the tenant. Disputes usually arise because the parties interpret differently what counts as “normal wear and tear” and what counts as “damage”.
In Switzerland, cantonal tenant associations (e.g. Mieterinnen- und Mieterverband / MV, Asloca) publish detailed tables on the expected lifespan of individual items (Lebensdauertabellen). These are not legally binding, but tenancy conciliation authorities generally take them into account.
Maintenance obligations
Minor repairs (small maintenance, Kleinreparaturen) are the tenant’s responsibility, but only if the contract expressly provides for this and only up to a specified amount. Under federal law, this amount may not exceed 10% of the annual rent, and in individual cases it is typically limited to around CHF 150–200.
⚠️ The exact threshold is determined by cantonal practice and the individual contract — this is one of the most frequently misunderstood areas.
Settlement of ancillary costs (Nebenkosten)
If you pay ancillary costs as a flat rate (Pauschale), the landlord does not have to provide an accounting. However, if itemised accounting (Akonto) has been agreed, you must receive a detailed statement every year. If you do not receive it, you may request it in writing — and if the landlord does not comply, you can turn to the tenancy conciliation authority.
What are the rules for moving out in Switzerland?
Notice periods and notice dates
In Switzerland, notice periods and notice dates (Kündigungstermine) are regulated by law, but the contract may make them stricter.
Type of tenancy | Statutory notice period | Customary notice date |
|---|---|---|
Residential lease | 3 months | According to local custom (e.g. March 31, June 30, September 30) |
Commercial premises | 6 months | According to local custom |
Furnished room | 2 weeks | End of the month |
The notice must be sent by registered mail (Einschreiben) at least by the statutory deadline before the termination date. If you give notice, missing the deadline means you remain obliged to pay rent until the next statutory termination date.
⚠️ The specific termination dates may vary by canton and locality. Check the local custom (Ortsgebrauch) before signing the contract.
Proposal of a replacement tenant (Nachmieter)
If you wish to move out before the contractual termination date, you are entitled to propose a solvent, suitable replacement tenant (Nachmieter). If the landlord rejects the proposed person without good reason, you may be released from the obligation to continue paying rent. The proposal must be made in writing, and sufficient information about the candidate must be provided (income, references).
How does the handover of the apartment work?
The move-out inspection (Wohnungsabnahme / état des lieux de sortie)
When moving out, a joint inspection must be carried out with the landlord or their representative. During this inspection, all observed damage and deficiencies must be recorded in writing in a handover report (Übergabeprotokoll). Both parties must sign it, and each party must receive a copy.
What to do before the inspection:
Photograph all walls, floors, fixtures, and appliances.
Carry out minor repairs (removing nails, small paint defects) that the contract assigns to the tenant as an obligation.
Check that you have all keys, remote controls, and access devices.
If the landlord notes damage during the inspection that you believe is not your responsibility, do not sign the report without reservation. Write: “Signed, but with reservation regarding [specific point]” (unterzeichnet unter Vorbehalt bezüglich…).
Return of the deposit
The landlord must take action to return the deposit within a reasonable time after the tenancy ends. If there are disputed items, the landlord may not withhold the full amount indefinitely without prior court approval — the undisputed portion must be refunded.
If the deposit has still not been returned after 30 days and you have not received a written explanation, contact the bank where the blocked account (Sperrkonto) is held and ask for information on the conditions for release.
How can a tenancy dispute be resolved?
Mandatory conciliation procedure (Schlichtungsverfahren)
In Switzerland, before taking a tenancy matter to court, you must first go to the cantonal tenancy conciliation authority (Schlichtungsbehörde / autorité de conciliation). This procedure is free of charge, and the authority will try to bring the parties to an agreement. If that fails, it issues a so-called authorisation to sue (Klagebewilligung), which allows the matter to be brought before the court.
The deadline for submitting a conciliation request is fixed in certain cases — for example, 30 days when challenging a termination notice.
Rental court (Mietgericht / tribunal des baux)
If conciliation fails, the case continues before the cantonal rental court. In some cantons (e.g. Zürich, Geneva), there is a separate specialised rental court; in others, the ordinary civil court has jurisdiction.
Help from tenants’ associations
Swiss tenants’ associations (Mieterinnen- und Mieterverband / MV, Asloca in the French-speaking cantons) provide legal advice and representation to their members. The annual membership fee is typically around CHF 50–100 and can pay for itself even in a single dispute.
Hungarian-language legal assistance is only limitedly available in Switzerland; in most cases, a German-, French- or Italian-speaking adviser from the tenants’ association is sufficient, but in more complex matters it is worth looking for a bilingual lawyer.
How do the cantons differ from one another?
The federal Code of Obligations (OR) provides a uniform framework, but there are cantonal differences in many areas:
Aspect | Example of a cantonal difference |
|---|---|
Termination dates | In Zürich and Bern, local custom (Ortsgebrauch) differs from, for example, Geneva |
Organisation of the rental conciliation authority | In some cantons it is an independent office, in others it operates within the court system |
Rental court | Specialised in Zürich and Geneva, ordinary civil court in other cantons |
Level of tenant protection | Geneva and Vaud traditionally have stronger tenant-protection practices |
Housing shortage and market pressure | Zürich, Geneva, Basel, Zug: tight market, higher rents, more disputes |
Practical tip: before moving in, visit the website of the local cantonal tenants’ association (MV or Asloca) and check the local termination dates and the contact details of the conciliation authority.
Hungarian aspects worth taking into account
Language barriers. Swiss tenancy agreements are typically drafted in German, French or Italian. Before signing, it is worth making sure you understand every clause — either with a translation tool or with the help of a bilingual acquaintance. If you do not understand something, ask the landlord in writing; the reply should also be in writing.
References and proof of solvency. In Switzerland, landlords usually ask for a copy of the Betreibungsregisterauszug (debt register extract) and an employer’s certificate. As a Hungarian citizen who has recently arrived, you may not yet have a Swiss debt-register history — it is worth flagging this in advance and supplementing it with other documents (e.g. bank statements, a reference from a previous landlord).
Registration obligation. In Switzerland, you must register with the local residents’ office (Einwohnerkontrolle / contrôle des habitants) within 14 days of moving in. This is not only a legal obligation, but also a condition for maintaining your residence permit (B permit / Ausländerausweis B).
If you return home. If you move back to Hungary, you must terminate the tenancy in compliance with the notice periods. The return of the deposit can also be requested to a foreign bank account, but the process may be slower — it is worth arranging this in good time.
Practical checklist: steps to prevent disputes
Before moving in:
Read the full contract; ask in writing about anything you do not understand.
Check whether the deposit is held in a blocked bank account (Sperrkonto).
Attend the move-in inspection and sign the move-in protocol (Einzugsprotokoll) only if it lists every existing defect.
Photograph all rooms, fixtures, and appliances, with dates.
During the tenancy:
Keep all communication in writing (email is sufficient, but registered mail is recommended for important matters).
Report defects immediately, in writing.
Keep proof of rent payments.
If the landlord does not carry out the necessary repairs, set a reasonable deadline in writing and indicate that you may take the matter to the rental court.
Before moving out:
Check the notice period and the termination date – give notice by registered mail.
Carry out the minor repairs that the contract assigns to the tenant.
Request written confirmation of the handover of keys and equipment.
Attend the move-out inspection and sign the protocol only with reservations if there are disputed items.

In Brief
In Switzerland, most sublease disputes arise around the deposit, maintenance obligations and the settlement of ancillary costs. When moving out, the notice period, proposing a replacement tenant and the handover report are decisive: what is not recorded in writing is later difficult to prove.
Key Takeaways
- Check whether the contract specifies the net rent, the type of Nebenkosten and the details of the blocked deposit account.
- Challenge an excessively high initial rent within 30 days of moving in if the previous tenant paid less.
- Before moving out, observe the local notice deadline and send the notice by registered mail.
- Propose a replacement tenant in writing, with proper details; if the landlord rejects them without good cause, you may be released from further rent payments.
- At the move-out inspection, every damage must be recorded in writing, and if there is a disputed item, it is advisable to sign the report with reservations.
- If the ancillary costs are a flat rate, there is no itemised settlement; if they are Akonto, you must receive a detailed annual statement.
Frequently Asked Questions
How much deposit can be requested for a sublease in Switzerland?
Under the law, the deposit may be no more than three months’ net rent. The landlord must place it in a blocked bank account opened in your name and may not keep it in their own account.
When can the initial rent be challenged?
If the previous tenant paid a lower rent and the new rent is significantly higher by comparison, it can be challenged before the tenancy court within 30 days of moving in. After the deadline has passed, this right can no longer be enforced.
What counts as normal wear and tear when moving out?
Normal wear and tear cannot be charged to the tenant; examples include faded paint or minor scratches on the floor. The landlord may withhold part of the deposit only on the basis of actual, documented damage, and the amount must be proportionate to the damage.
Do ancillary costs always have to be settled?
No. If the ancillary costs are paid as a flat rate, the landlord does not have to provide an itemised settlement. However, if there is an Akonto arrangement, you must receive a detailed annual statement.
What is the notice period for residential leases in Switzerland?
For residential leases, the statutory notice period is 3 months. However, the exact notice date may vary according to local custom, so it should be checked before signing the contract.
Can you move out earlier by proposing a replacement tenant?
Yes. If moving out would happen before the contractual notice date, a solvent and suitable replacement tenant may be proposed. If the landlord rejects them without good cause, release from further rent payments may be possible.
What should be done at the move-out inspection?
Damages and deficiencies must be recorded in writing in the handover report, and both parties must sign it. If there is a disputed item, it is advisable to sign with reservations rather than without reservations.
