In situations where the landlord is following the eviction process with a tenant, a notice or agreement shows the court that the landlord has given a fair warning. Hopefully, the landlord has documented all the written letters and communications sent to the tenant. A good paper track can save the owner time in the future if a judge is involved. If your tenant violates the rental agreement, for example. B maintains a dog despite the lease that prohibits pets, you must send a written warning to the tenant before sending a termination letter. A letter of formal notice gives your tenant time to repair the offense by removing or undressing the dog. After sending the official message, you will most likely have the attention of the landlord or tenant. At this point, it is best to look into the problem before involving the lawyers.
