Early lease termination in Switzerland: finding a replacement tenant

How to terminate a lease early in Switzerland: the solvent replacement tenant rule, template letter, notice periods, landlord rights, and options if refused.

Do you need to leave your home before the contractual end date? Swiss law allows you to leave without paying rent until the end of the lease, provided you find a solvent replacement tenant. This guide explains how to proceed, the landlord's rights, and what to do if things stall.

At a glance

  • You can terminate a lease at any time with 3 months' notice on the contractual termination dates (often end of March, June or September).
  • To leave outside those contractual dates, you must find one or more solvent replacement tenants who are willing to take over the lease on the same terms.
  • The landlord has in principle a reasonable period (often 30 days) to accept or refuse. Without a valid reason, they must accept.
  • Until a replacement tenant has been accepted, you remain liable for the rent until the contractual termination date.

What you need to understand

A tenancy agreement in Switzerland binds the tenant until the next contractual termination date, subject to the notice period (generally 3 months). But life does not follow lease dates: a job relocation, buying a property, a separation, an opportunity elsewhere.

The law therefore provides two ways to exit early:

  • Extraordinary termination for good cause: serious grounds making continuation of the tenancy unreasonable. Rare and difficult to enforce.
  • Presenting a replacement tenant: the most common route. You propose a new tenant to your landlord. If they refuse without a valid reason, you are released from the lease.

This possibility is governed by Art. 264 CO (Code of Obligations).

Requirements for the replacement tenant

The candidate you put forward must meet several criteria to be considered "acceptable":

  • Solvent: sufficient income for the rent (often required: net monthly income of at least 3 times the gross rent).
  • No debt enforcement proceedings: a recent extract from the debt enforcement register showing no negative entries.
  • Willing to take over on the same terms: same rent, same ancillary costs, same duration, same general conditions.
  • Acceptable to the landlord: no valid objective ground for refusal (known bad payer, proven hostility from neighbours, etc.).

Good practice: put forward several candidates (ideally 3) to maximise the chances of acceptance.

Steps to follow

1. Notify your landlord of your intention

  • Send a registered letter announcing your wish to leave the property on a specific date and your intention to present a replacement tenant.
  • Ask for the exact lease terms to pass on to the candidates.

2. Find candidates

  • Post the listing on homegate.ch, immoscout24.ch, anibis.ch, or local rental groups.
  • Make it clear that this is a lease takeover (sublease or assignment), on a given date, on the same terms.
  • Conduct the viewings yourself or with the landlord.

3. Put together each candidate's file

  • Identity document or residence permit.
  • Employment contract and last 3 pay slips.
  • Debt enforcement register extract (less than 3 months old).
  • Cover letter or letter of introduction.
  • Direct contact details for the landlord.

4. Formally present the candidate(s)

  • Send the landlord a registered letter listing the candidate(s) with their complete file.
  • State the date from which you wish to be released.
  • Keep a copy and the acknowledgement of receipt.

5. The landlord's deadline

  • The landlord has a reasonable period (often 30 days, case law varies) to assess the file and respond.
  • If there is no reply within that period, you may treat the silence as tacit acceptance (confirm with your local ASLOCA branch depending on your canton).

Template letter for presenting a replacement tenant

Dear Sir or Madam,

As indicated in my letter of [date], I wish to terminate my tenancy agreement for the flat at [address] on [desired date].

In accordance with Art. 264 CO, I am putting forward the following candidate to take over the lease on the same terms:

Last name, first name: [...] Date of birth: [...] Current address: [...] Occupation and employer: [...] Contact details: [...]

Please find enclosed: identity document, employment contract, last 3 pay slips, debt enforcement register extract.

I would be grateful if you could confirm your acceptance in writing as soon as possible.

Yours sincerely,

[Signature]

If the landlord refuses

The landlord may only refuse on the basis of a valid reason. Acceptable grounds include:

  • Proven insolvency of the candidate.
  • Significant debt enforcement proceedings on record.
  • An occupation incompatible with residential use.
  • Objective risk of neighbourhood disturbance (poor past references).

Grounds that are not valid:

  • Unjustified personal preference.
  • Refusal on discriminatory grounds (nationality, origin, family situation).
  • Intention to keep the flat empty in order to raise the rent.

Recourse

  • Challenge the refusal by registered letter, requesting the precise written reason.
  • Contact the rental conciliation authority in your canton (free or low-cost, mandatory before going to court).
  • If conciliation fails, you have 30 days to bring the matter before the tenancy court.
  • During this procedure you remain in principle liable for rent, but you may claim damages if the refusal was abusive.

Subletting

Not to be confused with a lease takeover:

  • In a sublease, you remain the main tenant and sign a sub-tenancy agreement with a third party.
  • You must obtain the landlord's consent, which they can refuse only on valid grounds.
  • You remain responsible for any damage, the rent and compliance with the house rules.
  • The sublease rent cannot be abusively higher than the main rent (unless you are providing furniture or services).

Documents to keep

  • Original tenancy agreement.
  • Registered letters exchanged with the landlord (notice, presentation of candidates, any refusal).
  • Complete files of the candidates presented (dated).
  • Postal acknowledgements of receipt.
  • Written decision of acceptance or refusal.

Common mistakes

  • Leaving without having presented a replacement tenant. You remain liable for the rent until the next contractual termination date, even if the flat sits empty.
  • Presenting only one weak candidate. The landlord has valid grounds to refuse, and you have to start over.
  • Not putting everything in writing. Everything must go by registered post to have dated proof.
  • Assuming the landlord can refuse without reason. Wrong. Without a valid reason, a refusal cannot be upheld.
  • Confusing assignment and subletting. Two different legal mechanisms with different consequences.
