Wyoming does not have a unified statewide court portal for public name searches. The state is organized into nine judicial districts covering 23 counties, and online court access is fragmented — Laramie County (Cheyenne) and Natrona County (Casper) have some online case lookup tools, but most Wyoming counties require direct contact with the district court clerk for records inquiries. Wyoming's judiciary does not provide a single public-facing statewide search interface.
Wyoming is the least populous state in the country with roughly 580,000 residents spread across a vast geographic area. The state's economy is heavily dependent on energy extraction — oil, natural gas, and coal — creating a mobile workforce with address histories that often span multiple Wyoming counties and neighboring states. If you're comparing search approaches across the Mountain West, our people search by state guides show how Wyoming compares to neighboring states.
Key takeaways
- Wyoming has no unified statewide court portal — Laramie and Natrona counties have some online access tools, but most of the remaining 21 counties require direct district court clerk contact.
- Laramie County (Cheyenne) and Natrona County (Casper) together hold roughly half of Wyoming's population and generate the majority of the state's court filing volume.
- Wyoming's energy extraction workforce — oil, gas, and coal — is highly mobile and creates address histories that often span multiple counties and neighboring states including Colorado, Montana, and North Dakota.
- Wyoming borders six states — Colorado, Utah, Idaho, Montana, South Dakota, and Nebraska — and cross-state records are relevant for residents near any of these borders, particularly along the Colorado Front Range corridor in Laramie County.
How searches work in Wyoming
Wyoming searches require county identification as a first step, since no statewide portal exists. District courts are Wyoming's trial courts of general jurisdiction, handling all felony criminal cases, major civil matters, and family law. Circuit courts handle misdemeanors and civil matters below the district court threshold. Both court levels maintain records at the county level with no centralized public access portal.
Property records in Wyoming are maintained by each county's clerk office. Most Wyoming counties offer limited online property search access, with Laramie and Natrona counties having the most developed online systems. Our find someone by name and city guide explains how to use city context to establish the correct Wyoming county before entering local record systems.
Industry insight
Wyoming's energy workforce mobility creates the most distinctive search challenge in the state. The Powder River Basin coal counties in the northeast — Campbell County (Gillette) and Converse County — have a workforce that moves between Wyoming, Montana, and the Dakotas depending on where the contracts are. A person with a Gillette address in a database may have spent only one rotation there before moving to a Williston, North Dakota project or returning to a home base in Colorado.
The Colorado Front Range connection is the most important cross-state consideration for Laramie County searches. Cheyenne is 100 miles from Denver along I-25, and many Cheyenne residents commute to the Denver metro, have prior Colorado address histories, and may have court records in Larimer or Weld counties, Colorado. The Colorado courts electronic filing system is a standard supplement for any Cheyenne-area search.
Common mistakes when searching by name in Wyoming
- Treating an energy county address as a long-term residence — Campbell County (Gillette) and Sublette County (Pinedale) addresses often reflect temporary energy project workers rather than permanent residents.
- Not checking Colorado for Laramie County searches — Cheyenne's I-25 corridor connection to the Denver metro means Colorado Front Range records are routinely relevant for Cheyenne-area residents.
- Assuming online access is available across Wyoming — most of the state's 23 counties have no online court case search, and direct clerk contact is the only option for rural Wyoming counties.
- Overlooking circuit courts for misdemeanor records — Wyoming's two-tier district/circuit court structure means misdemeanors are in circuit court, not district court, and both must be checked for a complete county-level search.

Wyoming crime statistics are compiled by the Wyoming Division of Criminal Investigation through the FBI's Uniform Crime Reporting program. Laramie and Natrona counties account for a disproportionate share of Wyoming's total reported crime by volume. Energy boom-and-bust cycles affect crime rates in extraction counties. When running a criminal record search in Wyoming, county identification is a prerequisite since no statewide portal exists.
Public records law
Wyoming's public records framework is the Wyoming Public Records Act, codified at W.S. § 16-4-201 et seq. The Act declares that all public records shall be open for inspection by any person during regular business hours except as otherwise provided. Wyoming's framework creates a presumption of disclosure.
Wyoming has a limited expungement statute under W.S. § 7-13-1401 et seq. that allows for the expungement of certain misdemeanor and some felony convictions after waiting periods. Successfully expunged records are sealed from public access at the court level.
Official public record sources in Wyoming
| Agency | Records maintained | Notes |
|---|---|---|
| Wyoming District Court Clerks (23 counties) | Felony criminal cases, major civil litigation, and family court records | No unified statewide portal. Laramie and Natrona counties have some online access tools. Most other counties require direct district court clerk contact. |
| Wyoming Circuit Court Clerks (23 counties) | Misdemeanor criminal cases and minor civil matters | Separate from district courts. No unified portal. Both district and circuit clerk contacts required for a complete county-level search. |
| Wyoming Division of Criminal Investigation (DCI) | Statewide criminal history records; sex offender registry | Sex offender registry is publicly searchable at wyomingsexoffender.dci.wyo.gov. Full criminal history background checks require authorized access. DCI records are the most useful statewide criminal resource for public searches. |
| Wyoming Vital Statistics (WYDOH) | Birth, death, marriage, and divorce records | Wyoming Department of Health maintains vital records. Marriage and divorce records available to qualified requesters through health.wyo.gov. County clerks also maintain local marriage records. |

Wyoming marriage records
Wyoming marriage licenses are issued by the county clerk in the county where the license is obtained. The Wyoming Department of Health maintains a statewide marriage index from 1941 forward — requests go through health.wyo.gov by mail. Laramie and Natrona counties generate the highest marriage license volume in Wyoming.
For a full guide to how marriage record searches work across all states, see the marriage record search guide.
Wyoming divorce records
Divorce cases in Wyoming are filed in district court in the county where either party resides. Wyoming requires at least 60 days of state residency before a divorce can be filed. The Wyoming Department of Health maintains a statewide divorce index from 1941 forward. Individual case records are held by the district court clerk in the filing county.
Laramie County generates Wyoming's highest divorce filing volume. For a full guide to how divorce record searches work across all states, see the divorce record search guide.
Population context
Wyoming's 581,000 residents are distributed across 23 counties covering 98,000 square miles — the least populous state in the country. Laramie County (Cheyenne) holds roughly 100,000 people. Natrona County (Casper) holds roughly 80,000. Campbell County (Gillette) holds roughly 47,000. Sweetwater County (Rock Springs, Green River) holds roughly 43,000. Teton County (Jackson) holds roughly 23,000.
The remaining 290,000 Wyomingites are distributed across 18 counties, many with populations under 10,000. Wyoming has some of the least dense counties in the contiguous United States — Niobrara County has fewer than 2,500 residents spread across 2,600 square miles. Address histories in Wyoming often span multiple counties as residents follow energy employment. A name and relative search is particularly valuable for establishing stable contact in a state where energy employment drives significant geographic mobility.
Example search scenarios in Wyoming
Searching by name and city
Wyoming city-to-county mapping: Cheyenne → Laramie County; Casper → Natrona County; Gillette → Campbell County; Rock Springs → Sweetwater County; Sheridan → Sheridan County; Green River → Sweetwater County; Evanston → Uinta County; Riverton → Fremont County; Jackson → Teton County; Cody → Park County; Laramie → Albany County. For Cheyenne searches, Larimer County, Colorado (Fort Collins) records are a standard supplement given the I-25 corridor integration.
Checking court records
District court clerk contact in the identified county for felony and civil records → circuit court clerk for misdemeanor records → Wyoming DCI sex offender registry for statewide criminal context. For Cheyenne-area searches, Colorado courts records for Larimer and Weld counties are a standard supplement. See our court record search guide for how Wyoming's fragmented two-tier structure compares nationally.
Searching when the city is unknown
Without a statewide portal, the Wyoming DCI sex offender registry is the most practical statewide starting point for criminal history context. A people search service is especially valuable in Wyoming because the fragmented court system and mobile energy workforce make county identification from address history a prerequisite for direct clerk contact.
Major cities in Wyoming
Cheyenne
Cheyenne (est. 65,132 — U.S. Census Bureau, 2023 ACS) is the state capital and the seat of Laramie County. Cheyenne sits on the I-25 corridor 100 miles north of Denver — many residents commute to the Denver metro and have Colorado Front Range address histories. The city's state government and military presence (F.E. Warren Air Force Base) create two distinct workforce populations: stable government employees and mobile military families with PCS-cycle address volatility. Laramie County District Court is Wyoming's busiest by filing volume.
Casper
Casper (est. 58,651 — U.S. Census Bureau, 2023 ACS) is the seat of Natrona County and Wyoming's central commercial hub. Casper's oil and gas economy creates above-average address turnover — energy sector employees move with project cycles. Natrona County District Court is Wyoming's second-busiest. The city serves as the supply and services hub for a large region of central Wyoming's energy counties.
Gillette
Gillette (est. 32,735 — U.S. Census Bureau, 2023 ACS) is the seat of Campbell County in the Powder River Basin coal region. Gillette's coal economy has experienced significant boom-and-bust cycles — address databases for Gillette are among the most volatile in Wyoming. Campbell County's workforce draws from multiple states, and addresses here often reflect temporary project workers rather than permanent residents.
Rock Springs
Rock Springs (est. 23,319 — U.S. Census Bureau, 2023 ACS) is the largest city in Sweetwater County in southwestern Wyoming. Rock Springs is the hub of Wyoming's natural gas industry in the Green River Basin. Like Gillette, Rock Springs has a mobile energy workforce — Sweetwater County addresses often reflect project-based residency rather than permanent settlement. The city's proximity to Utah means some residents have prior Utah records.
Jackson
Jackson (est. 10,533 — U.S. Census Bureau, 2023 ACS) is the seat of Teton County and Wyoming's tourism and outdoor recreation hub. Teton County has Wyoming's highest per-capita income and one of the most expensive housing markets in the country. Jackson's tourism economy creates significant seasonal workforce turnover. Many Jackson workers live in neighboring Idaho (Bonneville and Teton counties) due to lower housing costs — Victor and Driggs, Idaho are effectively Jackson workforce communities.
County systems in Wyoming
Laramie County
Laramie County (pop. est. 100,000 — U.S. Census Bureau, 2023 ACS) contains Cheyenne and is Wyoming's most populous county. Laramie County District Court is the state's busiest. The county's Colorado border creates significant cross-state records relevance — Colorado courts electronic filing system is a standard supplement for Cheyenne-area searches. F.E. Warren AFB adds a military population with PCS-cycle address volatility.
Natrona County
Natrona County (pop. est. 80,000 — U.S. Census Bureau, 2023 ACS) contains Casper and is Wyoming's second-most populous county. Natrona County's oil and gas economy creates above-average workforce mobility. The county has some online court access tools, making it more accessible than most Wyoming counties for initial records research.
Campbell County
Campbell County (pop. est. 47,000 — U.S. Census Bureau, 2023 ACS) contains Gillette and is the heart of the Powder River Basin coal region. Campbell County's address databases are highly volatile due to coal industry boom-and-bust cycles. The county draws workers from Wyoming, Montana, the Dakotas, and neighboring states on project cycles.
Sweetwater County
Sweetwater County (pop. est. 43,000 — U.S. Census Bureau, 2023 ACS) contains Rock Springs and Green River and anchors southwestern Wyoming's natural gas industry. Utah border proximity means some Sweetwater County residents near the Uinta Basin have Utah records from prior residences. The county's energy economy creates above-average address turnover.
Teton County
Teton County (pop. est. 23,000 — U.S. Census Bureau, 2023 ACS) contains Jackson and Grand Teton National Park. The county's extreme housing costs push much of its workforce into neighboring Idaho, creating a cross-state commuter dynamic. Teton County, Idaho (Driggs, Victor) and Bonneville County, Idaho records are relevant for many people who work in Jackson but live across the state line.

| Instant Checkmate | Particularly useful in Wyoming because the fragmented court system, mobile energy workforce, and no statewide portal make county identification from address history a prerequisite before any direct clerk contact. | Quick first-pass searches |
| TruthFinder | Useful for multi-state address history context — particularly valuable for energy county searches where home-state records in Colorado, Montana, or Texas may be more substantive than Wyoming records. | Expanded public-record context |
Frequently asked questions
Does Wyoming have a statewide court records search?
No. Wyoming does not have a unified statewide court portal for public name searches. District courts (felonies, major civil, family) and circuit courts (misdemeanors, minor civil) maintain separate records at the county level across all 23 counties. Laramie and Natrona counties have some online access tools, but most Wyoming counties require direct contact with the relevant court clerk. The Wyoming DCI sex offender registry at wyomingsexoffender.dci.wyo.gov is the most useful statewide criminal records resource available to the public.
Can you look up marriage or divorce records in Wyoming?
Yes, through the Wyoming Department of Health. WYDOH maintains a statewide marriage index from 1941 forward and a divorce index from 1941 forward — requests go through health.wyo.gov by mail. For county-level marriage licenses, the county clerk where the license was issued is the authoritative source. Divorce records are held by the district court clerk in the filing county. Laramie and Natrona counties generate the highest marriage and divorce filing volume in Wyoming.
Can I use these searches for jobs, housing, or insurance decisions?
No. The services discussed on this page are not consumer reporting agencies and the information here is not a consumer report. They should not be used for employment, tenant screening, insurance underwriting, credit, or any other purpose regulated by the Fair Credit Reporting Act.
