Terminating a rental agreement in Switzerland is only possible at specific dates and must use the official cantonal form.

## Termination dates and notice periods


- Common dates: 31 March, 30 June or 30 September
- Minimum notice: 3 months for residential (CO Art. 266a)


## Official cantonal form is mandatory


Landlords must use the official cantonal form (CO Art. 266l). Termination by email is invalid.


> **Important**

> The official form varies by canton. Always use the form for the canton where the property is located.
