Restrictions and Confidentiality
Not every document in the Boulder County residents directory is fully public. Colorado law protects certain information. Birth certificates less than 100 years old are restricted to immediate family. Death certificates are closed for 20 years from the date of death. Adoption records are sealed permanently. These restrictions are set by state statute and apply to all counties.
Court files may be sealed in some circumstances. A judge can order a case sealed if there is good reason. Criminal defendants can petition to seal records after completing their sentence. If the petition is granted, the case disappears from the public index. Juvenile cases are sealed automatically. Family law cases may have redactions to protect children or victims of abuse. Chief Justice Directive 05-01 provides guidance on court record access.
Even in public records, some information is redacted. Social Security numbers are always removed. Bank account numbers are blocked out. Home addresses of domestic violence victims are not disclosed. These redactions protect privacy while maintaining public access. The county must follow the law when deciding what to release. If you disagree with a denial, you can appeal. The denial notice will explain your rights.
