Municipal Court

The mission of the Frederick Municipal Court is to ensure that there is an accessible and open court process where due process of law and fundamental fairness are afforded to all who appear before the Court, and that customer service by administrative staff is of the highest priority.

The Frederick Municipal Court is open to the public.  Those who have received a summons, are expected to appear in court on their scheduled date.  If you are appearing in person for any Court proceeding, the following procedures will be strictly followed and enforced.
  • If you are ill or have a fever, cough or other symptoms associated with COVID-19 or have had contact in the last 14 days with any person who has been diagnosed with COVID-19, you may not enter the building. Please call the clerk to reschedule.
  • You are not required to wear a mask to enter the building
  • To comply with social distancing rules, only the defendant (and one parent if defendant is a juvenile) may appear in court.  An attorney may also appear with defendant.
  • Please avoid touching the podium or other objects while you are in the building.  The facility and the courtroom will be sanitized before and after each court session.

1.  You may call the court clerk at (720) 382-5531 or email the court.  If you have a motion, court request, proof of completion of a class or community service hours, you may fax it to the clerk at 720-382-5540, email it or mail it to the clerk at P.O. Box 639, Frederick, CO 80530. Payments may be made by mail, in person or by contacting the court clerk by phone.

2. If you would like to appear by phone or video where you can speak to a judge and a prosecutor about your case, please contact the court clerk to schedule a Zoom video hearing. 

3. Certain cases may be eligible for resolution without appearance in court. If you have an early payment discount option set forth on your summons, you may take advantage of that discount up through and including your currently scheduled court date.  If you do not have the early payment discount option marked on your summons, but are interested in learning if your case is eligible for such disposition, please contact the court clerk during normal business hours.

4. Individuals with active warrants out of the Frederick Municipal Court should contact the court clerk to discuss options for their case.
