FACTSealing removes records from public search but they still exist at the courthouse and may appear in FBI records (Identity History Summary).
MYTH"Free 'instant background' sites have Sully County data."
FACTOnly the official South Dakota state repository has verified, current Sully County data. Free sites often have stale data.
MYTH"The Sully County assessor's value is what I'll sell my home for."
FACTThe Sully County assessor's value is for property tax purposes only — usually below market value.
MYTH"All county records older than 50 years are public."

Does an arrest show up on a background check before conviction in South Dakota?
Yes — in South Dakota, an arrest can appear on a name-based background check from the moment of booking, even before any court ruling. Whether it appears on an employment screening depends on the type of check (name-based vs. fingerprint-based) and how recent the arrest is.
What's the difference between sealing and expunging a record in South Dakota?
In South Dakota, a sealed record is hidden from public view but still exists and remains visible to law enforcement, licensing boards, and some employers. An expunged record is treated by South Dakota law as if it never happened — though FBI and federal records may persist regardless of state action. The relief process runs through the sentencing court.
How do I run a South Dakota background check?
South Dakota background checks are handled by the South Dakota Division of Criminal Investigation. Name-based searches are available through the official state portal (per-search fee applies). Fingerprint-based checks — required for licensing, foster care, and many employers — must be submitted through an approved vendor.
