The term of notice of indefinite contracts is one calendar month. In other words, if the tenant moves out in May, the cancellation notification must be delivered to Retta Isännöinti by the end of April in order for the lease to cease by the end of May. The rent has to be paid during the cancellation time, as in the earlier example mentioned, the rent for May.
If you wish to cancel your apartment, please print and fill out the cancelling form.
