Definition
To expunge a legal record is to officially remove, obliterate, or destroy it so that it no longer exists as an accessible entry in a court, law enforcement, or government database. In modern legal usage, expungement is the primary mechanism by which individuals petition a court to eliminate records of arrests, charges, or convictions from public and official access.
Expunge carries two related but distinct applications in law:
1. Record expungement (criminal and civil): A court order directing that specified records — arrest records, court files, conviction entries — be physically destroyed, electronically deleted, or sealed to the point of legal nonexistence. The effect varies by jurisdiction: some statutes treat an expunged record as never having existed; others merely restrict access without mandating destruction.
2. Obliteration of a document or entry: The older, narrower sense — erasing or blotting out a specific entry, signature, or passage from a legal instrument or official record. This usage appears throughout historical court records and treatises and is the sense captured in the historical dictionaries.
Common Language
Modern common usage (Wiktionary): To erase or strike out; to eliminate completely; to delete permanently.
Historical common usage (Webster's 1913): To blot out, as with pen; to rub out; to efface designedly; to obliterate; to strike out wholly.
The common and legal senses share surface meaning — removal, erasure — but diverge sharply in legal consequence. When a court expunges a criminal record, it is not simply deleting a line of text. It is issuing a legal determination with downstream effects on rights, employment eligibility, licensing, and sometimes immigration status. The act may or may not involve literal destruction of documents; increasingly, "expungement" is a legal status applied to records that continue to exist in restricted form. Researchers reading the word in older legal instruments should not assume the modern procedural meaning applies.
Common Confusion
Expunge is frequently conflated with seal. Sealing restricts public access to a record but does not eliminate it — law enforcement and certain government agencies may still access sealed records. Expungement, in jurisdictions that apply it rigorously, goes further: the record is treated as nonexistent, and the individual may legally deny its existence in most contexts. Some statutes use the terms interchangeably or define "expungement" to mean what other statutes call "sealing," so the label alone does not determine the legal effect. Always consult the governing statute's definitions section.
Why It Matters in Research
The word expunge appears in two entirely different research contexts that researchers must not conflate.
In pre-20th-century sources, expunge appears most often in its documentary sense — striking a passage from a record, removing a judge's entry, or obliterating a deed provision. When you encounter "the record was expunged" in 19th-century case law, it may mean only that a specific clerical entry was physically struck, not that an entire case file was destroyed.
The modern procedural meaning — expungement as a remedial petition process — developed largely through 20th-century statutory reform, accelerating significantly from the 1970s onward as states built out diversion programs and juvenile justice reforms. Early expungement statutes were narrow; contemporary statutes vary enormously in what offenses qualify, waiting periods, the effect of the order, and whether expunged records remain accessible to prosecutors, licensing boards, or federal agencies.
A critical research trap: federal law does not recognize state expungements for most federal purposes. A record expunged under state law may still appear in FBI databases, affect federal firearm eligibility determinations, or be considered in federal sentencing. Corpus materials that discuss expungement without specifying the jurisdictional context of the consequences may be misleading.
For researchers tracing the evolution of expungement law, the corpus connection runs through juvenile record sealing (historically the origin of the concept), adult diversion programs, and the broader "clean slate" legislative movement of the 2010s–2020s. Each of these bodies of law treats the underlying concept somewhat differently.
Historical Dictionary Support
All three historical sources — Black's (1st and 2nd editions) and Anderson's — treat expunge in its narrow documentary sense: to blot out, to efface designedly, to obliterate, to strike out wholly. The definitions are nearly identical and trace back directly to the common English meaning captured in Webster's 1913.
None of the historical dictionary sources addresses the modern procedural meaning of expungement as a court-ordered remedy in criminal record law. This is an important gap. A researcher consulting these sources for guidance on how expungement orders operate, what they require, or what effect they carry will find nothing useful. The historical dictionaries are reliable for the documentary sense and nothing more.
Anderson's entry is a bare cross-reference to ALTER, CANCEL, and SCANDAL — appropriate companions for the documentary sense but unhelpful for the modern practitioner context.
Jurisdictional Note
Expungement law is almost entirely state-specific. Eligibility criteria, waiting periods, covered offenses, and the legal effect of an order differ substantially across states, and some states offer no expungement remedy at all for adult convictions. Federal criminal records are generally not subject to expungement through any standard petition process.
