A tenant’s lease said that the rent was due in advance by the third working day of each month. For more than two years he paid in the middle of the month or even later. The landlord warned him, and the payments came late again. The landlord then ended the lease without notice. On 11 January 2006 the Federal Court of Justice ruled on the case. Rent that is paid late again and again can be a reason for termination without notice. After repeated delays and a warning, even a single further delay can be enough.
