Searching Crook County: what to expect
Crook County keeps a modest online footprint — just one of the 11 sources below is the county's own; the rest is statewide coverage. No online docket is listed for the county itself; the Wyoming court records page maps the alternatives, and the clerk fills direct requests. The standout local source is crookcounty.wy.gov, covering parcel and property-tax data. For criminal records there's no county-level source online — the statewide routes on the Wyoming criminal records page cover that piece.

The 4-Step Crook County Records Pathway
1
Step 1 — Start at the Crook County clerk/courthouse
For most local records (court cases, property deeds, marriage licenses), the Crook County clerk's office is the first stop.
2
Step 2 — Use the Wyoming statewide systems
Criminal background, court case search, voter registration, and professional licensing are all run at the Wyoming state level — not by the county.
3
Step 3 — Federal sources for federal records
Federal court cases (PACER), federal tax liens (IRS), military records (NPRC), and immigration data (ICE) are all federal — not held by the county.
4
Step 4 — Cross-check before relying on data
Most county portals lag 24-48 hours behind the courthouse. For time-sensitive verification, call the clerk directly.
Five Things People Get Wrong About Crook County Records
MYTH"Crook County maintains all criminal records."
FACTCriminal records for Crook County are held by the Wyoming state repository, NOT the county. The county sheriff has only the local arrest log.
MYTH"Records sealed in Crook County are gone everywhere."
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 Crook County data."
FACTOnly the official Wyoming state repository has verified, current Crook County data. Free sites often have stale data.
MYTH"The Crook County assessor's value is what I'll sell my home for."
FACTThe Crook County assessor's value is for property tax purposes only — usually below market value.
MYTH"All county records older than 50 years are public."
FACTPartially false. Public-records rules vary by record type AND state. Court records and deeds are usually older-public; vital records remain restricted longer (often 75-125 years).

Frequently Asked Questions
Where do I find Crook County property records?
Crook County property records are maintained by the County Clerk, which records deeds, mortgages, and liens. Search the Property Ownership Maps License Agreement portal directly: https://www.crookcounty.wy.gov/elected_officials/assessor/property_ownership_maps/index.php.
Does an arrest show up on a background check before conviction in Wyoming?
Yes — in Wyoming, 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.
How long does an arrest stay on my record in Wyoming if I wasn't convicted?
In Wyoming, an arrest stays on your record indefinitely unless you petition the court to seal or expunge it, even if charges were dropped or you were found not guilty. Wyoming's rules for clearing non-conviction records are stricter than for convictions — start with the Wyoming DCI.
Are Wyoming criminal records public?
Mostly yes. Wyoming's public-records law makes adult arrests, court filings, and conviction histories accessible to anyone unless a specific statutory exemption applies. Juvenile cases and sealed records are generally excluded by statute.
