There is a strict process to follow whenever a landlord wants to terminate a lease for whatever reason, such as chronic untimely rent payment, constant property damage, or constant breach of lease agreement.  However, no matter how bad the situation is, a landlord cannot simply just change locks to lock a tenant out.  If a tenant is locked out, there may be legal penalties against the landlord for that action.  The landlord is required to get a court judgement first and if granted, a written eviction notice which would be then served to the tenant by the local sheriff. With so many factors to consider and the uniqueness of situation in different couples, many questions are bound to come up, some specific to one case, while other questions are more common-themed.  There are many of the commonly asked questions with resourceful answers here which may help you.
