This form is used by a landlord to notify a tenant that a problem exists and either wants the tenant to fix it (compliance) or vacate the premises. The Demand gives the tenant 3 days to comply or vacate and is sometimes referred to as a 3 Day Notice. For more information about the eviction process see our very popular title, Landlord and Tenant Guide to Colorado Leases and Evictions. You can also order this book as a kit and get all of our Eviction forms CD.
