Convictions for which more than 15 years have passed since the sentence was complete are private information at the BCA but are still public on MNCIS indefinitely.
Some documents filed into the public court record are ‘sealed’ by law and not accessible to the public. These often include documents that show financial or private health records.
Most juvenile records are considered private information. There is an exception when a youth is 16 or older and is charged with a felony offense. In these cases, there is a public hearing and record, even if the youth was adjudicated delinquent for the felony offense. You can see these records at the courthouse. They are not available online.
