How to use this Eviction Notice in Colorado

Serve the notice exactly as Colorado law allows and count the days from the day of service — the deadline is the first thing a judge checks; this generator does the counting for you. Do not include late fees in a pay-or-quit amount unless your state permits it. If the tenant pays the full amount in time, the notice is satisfied.

Keep a copy of the notice and the signed proof of service; you will attach both to the court complaint if the tenant does not comply.
