You can clear your Colorado record. Colorado law lets you seal most criminal justice records under C.R.S. §§ 24-72-701 to 24-72-711, with an automated path for records that qualify under the state's Clean Slate framework. Records that don't qualify for the automated process use a petition filed with the court, with the potential need for a hearing.
Colorado passed a Clean Slate bill that automates the sealing of most records as soon as they qualify, so you don't have to file anything to start that path.
Colorado requires a one-year waiting period before refiling a petition that was originally denied.
