In Austria you can eg end your Apartment lease via a specific court form that removes all ambiguity to wether they have received this in time or whatever. It cannot be refused since it is not filed with the landlord directly but served to him by court. Since Austria requires you to specify a known address to the government it is basically your problem then if you are not present. It is mostly used if your rental agreement contains language in conflict with the law about when you can end the lease. It basically reverses the roles since they cannot refuse the cancellation only appeal it and companies will obviously not do that based on leases that contradict law. You pay 100 EUR so you don’t have to communicate any more about it with the landlord which can be quite the good deal
