Ending a Swiss tenancy: how to avoid missing the right date

Two dates control an ordinary termination

A notice period tells you how far in advance you must act. A termination date tells you the dates on which the tenancy is allowed to end. You need to satisfy both. Reading only the words “three months” in a lease is not enough.

Start with the lease

Check whether the tenancy is fixed-term or open-ended. A fixed-term tenancy normally ends on the agreed date without ordinary notice. For an open-ended tenancy, read the clause on notice periods and permitted termination dates together, including any excluded dates.

The statutory residential baseline

Article 266c of the Code of Obligations provides a three-month notice period for residential premises, tied to the locally customary termination date or, where there is no local custom, the end of a three-month tenancy period. The parties may agree on a longer notice period or different termination dates.

What happens if the timing is wrong?

Under Article 266a, a notice that does not respect the applicable period or date takes effect on the next valid termination date. A small timing mistake can therefore extend the tenancy and the rent obligation beyond the planned move.

Build the timeline backwards

• Write down the intended final day of the tenancy.
• Confirm that this is a permitted termination date under the lease and local rules.
• Count back the full notice period.
• Allow delivery time and keep proof that the notice was received.
• Check whether every tenant named in the lease must sign.

If you need to leave earlier

Leaving before the next ordinary termination date is a separate situation. Article 264 addresses early return of the property and the conditions under which a suitable replacement tenant may release the departing tenant from future obligations. Do not assume that simply returning the keys ends the contract.

Before sending anything

Check the exact lease wording, the address for notices and any rules affecting a family home. When the deadline is close or the parties disagree, obtain advice from the competent conciliation authority, a tenants’ association or a lawyer.
