What rights do landlords have?

The landlord cannot prematurely end a fixed-term lease.

If the tenant remains in the property after the end of the fixed term with the express consent of the landlord, the lease is deemed to be a periodic lease. Periodic leases can be terminated by giving a month’s written notice.
If the tenant poses an immediate threat to the landlord, then the landlord can file for a “summary judgment.” A summary judgment allows the sheriff to evict the tenant even if the case is still being heard in the court.

If the tenant owes rent, the court can order the sheriff to attach the tenant’s properties to the house. It means the sheriff can take the tenant’s properties and sell them to compensate the landlord.

A landlord can also file for an “interdict,” preventing the tenant from taking his things as long as the arrears are not paid.
