How Swiss tenants lose thousands of francs

CO Art. 266a
CHF 6,600

CHF 6,600 for one day late

The letter arrived one day late — three months' rent lost. The receipt rule counts the day it reaches the landlord, not the postmark.

CO Art. 266m + Art. 169 CC

One signature missing. Termination invalid.

A married couple terminates the family home, but only one person signs. The termination is invalid — and cannot be cured afterwards. That is how the law protects the shared home.

CO Art. 143–150
CHF 7,200+

Flatmate moves out. You stay liable.

A flatmate moves out and thinks they're done. The joint lease says otherwise: whoever stays on the contract is liable for the full rent — including the leaver's share.

And those are only 3 of 7 ways your termination can fail.
