Is a cancellation by A-Post Plus valid?
The law does not prescribe a specific delivery method for many contracts; what matters is that the cancellation arrives on time. Swiss Post records A-Post Plus electronically with the delivery date. If your provider requires a handwritten signature or a specific channel, it may reject the cancellation. We do not check these requirements for you.
