An eviction notice letter is usually the first step in the eviction process. If a landlord wishes to evict a tenant, he or she must first provide the tenant with an official eviction notice letter. The letter outlines the reason for the potential eviction; nonpayment of rent is the most common reason for eviction, though other lease violations can also lead to eviction, such as violating a landlord's ﾓno petsﾔ policy. The eviction notice letter may specify a set amount of time that the tenant has to pay any unpaid rent or otherwise correct the lease violation to avoid eviction. Laws vary by state; an eviction notice letter will usually be a three day notice, five day notice, or a thirty day notice. Most laws state that an eviction notice letter must be delivered personally to the tenant or sent by registered or certified mail. If the tenant fails to correct the violation within the time specified in the eviction notice letter, a landlord may then proceed to have the tenant legally evicted though further legal action.
