A landlord cannot legally evict a tenant without obtaining a Possession Order and a Warrant of Possession. A Warrant of Possession directs the police to evict a tenant from the property. The police then contact the agent to arrange a time to go to the property, see the tenants off the premises, change the locks and formally take possession. The eviction must always be carried out by the police; the landlord cannot evict tenants themselves. Taking the law into own hands and failing to act according to the relevant legislation in jurisdiction will carry penalties for a landlord.
