Expungement is legal process that allows a criminal record to be essentially hidden from public view. The record does not disappear, it is just hidden. It will always be visible to the court system, law enforcement and government agencies. Many ex-offenders and felons looking for jobs have benefited by utilizing the expungement process.
expungement varies from state to state and is not available in all states. Your friend should seek legal counsel first to see if it a viable option for him and also to petition the court if it is an option. I would find the nearest legal aid office for assistance. You may qualify for low-cost or even free assistance with this process.
I hope this helps.
