Lease Agreement Minimum Period

Although the tenant is technically an intruder at this stage and possession of this type is not a true estate in the country, the authorities recognize the condition to make the tenant responsible for the rent. The landlord may distribute such a tenant at any time and without notice. Please suggest me how to evacuate a tenant from my house that is rented for 3 years with agreement, but is not registered and it ends on 20/05/2016, if he refuses to do so, and what the laws tell them, if they refuse to release and how long it will take, to clear them. Please indicate the procedures and laws I should follow. .
