If you seal your CORI, then potential employers, public housing agencies, even schools, and anyone else outside the criminal justice system will not be able to view it or have access to it. After your CORI is sealed you can truthfully state that you have never been arrested or charged with a crime. Remember however, that the courts, police and law enforcement can still view your CORI even if it is sealed. I hope this helps.

Note that a sealed record is utterly irrelevant should you apply for a firearms license. Answering "NO" to Questions 6, 7, and 10 will get you a denial and, possibly, a criminal charge for filing a false answer.
And no; saying you thought a sealed CORI allowed you to answer "NO" will not fly.
The foregoing is for general information purposes and does not establish an attorney-client relationship.
Your son's school will not be able to see a sealed CORI, nor will the Cub Scouts. Access to sealed CORI is limited to law enforcement entities (i.e. police departments, the courts, district attorneys offices), and the Department of Early Education and Care (EEC).
