Eviction is the legal process by which a landlord can expel a resident or tenant from a property. Some of the most common reasons a landlord will evict a tenant are the failure to pay rent on time, harboring other people or pets at the residence that are not authorized by the lease agreement, or the tenant’s participation in illegal or criminal activity within the rental premises. Regardless of the reason for eviction, a landlord must follow a formal eviction process that varies based on the county in which the property is located.
