Every state now provides some mechanism for limiting the public consequences of an old criminal record, and almost nobody uses them. This guide explains the full architecture of criminal record relief and how to work it. Part I distinguishes the five distinct remedies that get called "expungement" and explains what each actually does to a record. Parts II and III cover the threshold work that determines everything downstream: obtaining an accurate picture of what the record says across the court file, the state repository, the FBI identity history summary, and the commercial databases that employers actually use. Part IV works eligibility analysis variable by variable. Part V is the petition itself, including the evidence that persuades and the notice and hearing procedures that vary by state. Part VI covers what happens after an order issues, which is where most relief silently fails. Parts VII through X address the consequences that survive record relief — immigration, firearms, federal categorical bars, and registration — plus certificates of relief, pardons, and the automatic Clean Slate statutes. A closing verification list and authorities table make the guide usable as a working file.
