Terminate your flat lease in Switzerland

As a tenant, you terminate a flat lease in writing with three months’ notice to a contractual or customary local termination date (Art. 266c CO). What counts is when the landlord receives the notice. All tenants named on the lease must sign; for the family home, both spouses (Art. 266m CO).

Frequently asked questions

Terminating the lease after the tenant’s death?

If the tenant dies, the heirs can terminate with the statutory three months’ notice to the next statutory termination date, even if the lease would otherwise run longer (Art. 266i CO).

When must the notice arrive?

By the day before the three-month notice period starts. To move out on 30 April, it must arrive by 31 January.

We are married – who has to sign?

For the family home, both of you – even if only one of you is named on the lease. In our form you can both sign in the same field.

Can I leave earlier?

Yes, if you propose a solvent, acceptable replacement tenant who takes over the lease on the same terms.

Is a printed signature enough?

Not with legal certainty: the law requires a handwritten signature, and the landlord can challenge a printed one. The safest way is to print the template, sign it by hand and send it yourself by registered mail.
