Definition of "Kündigungsfrist"

Most phone, internet and electricity contracts in Germany have a cancellation period (Kündigungsfrist). If you want to end your contract, you must do it during that period. If you don't cancel your contract, it's renewed automatically. For example, you must cancel your Vodafone contract at least 3 months before it ends.

In some cases, you can cancel a contract early if there is a price increase, or if you move to an address where the service is not available1.

Rent contracts also have a Kündigungsfrist. The default is 3 months. It can be less than 3 months, but it can't be more.
