The process starts with a written notice to the tenant that his/her tenancy is being terminated, either in the form of a Notice to Quit, or a Demand for Compliance or Possession. Absent compliance with the directives of the Notice or Demand, the plaintiff/landlord thereafter must file an action under the Forcible Entry and Detainer (FED) statute, C.R.S. §13-40-101, et seq. Therein one finds the provisions for the timeliness of filing and service of a Complaint, Summons, and Affidavit of Mailing. Jurisdiction (the power of the Court to make a binding decision) may be over the tenant or tenants (personal jurisdiction), or over the building but not the tenant (in rem jurisdiction). Even after having obtained a judgment of possession and a Writ of Restitution (order to the sheriff to restore the landlord to possession of the premises), the process is fraught with specialized procedures and varied delays.
