Arapahoe County has an estimated 700,000 residents and is the eastern anchor of the Denver metro area. Aurora is the dominant city, but Centennial, Englewood, Littleton, and Cherry Hills Village also fall within the county. Several communities that residents commonly call "Denver" — including much of Aurora — are actually in Arapahoe County, meaning their court records and property filings are in Arapahoe County systems rather than Denver County systems.
Aurora's three-county footprint is the most consistent source of misdirected searches in the Denver metro. Aurora straddles Arapahoe, Denver, and Douglas counties. A search anchored to "Aurora" without knowing which part of Aurora the person lived in can route you to the wrong court system entirely. Arapahoe County is in the 18th Judicial District and uses Colorado's statewide iCourt portal — unlike Denver, which has its own separate system. For the broader Colorado context see our Colorado state guide.
Key takeaways
- Arapahoe County has approximately 700,000 residents (U.S. Census Bureau, 2023 ACS) — Aurora is the largest city and Colorado's third largest overall.
- Aurora spans Arapahoe, Denver, and Douglas counties — confirming which county a specific Aurora address falls in before searching courts is the required first step.
- Arapahoe County uses Colorado's statewide iCourt portal at iCourt.co — unlike Denver, which requires a separate portal. Select Arapahoe County in iCourt for both district court and county court access.
- The Arapahoe County courthouse is in Centennial (the county seat), not in Aurora. Aurora has a separate municipal court for city ordinance violations that is not in iCourt.

How record searches work in Arapahoe County
The Arapahoe County search sequence: confirm the county for the specific address first — especially for any Aurora address. Aurora ZIP codes 80010, 80011, 80012, 80013, 80014, 80015, 80016, and 80017 are primarily in the Arapahoe County portion of Aurora. The northwestern Aurora edge near the Denver border falls in Denver County; the southern reaches near E-470 can fall in Douglas County. A county assessor parcel lookup confirms jurisdiction in 30 seconds before committing to a court portal.
Once the Arapahoe County jurisdiction is confirmed, run iCourt at iCourt.co with Arapahoe County selected. iCourt covers both the district court (felonies, civil over $25,000, family, probate) and the county court (misdemeanors, traffic, civil under $25,000) for Arapahoe County in a single portal — a significant advantage over Denver's separate portal requirement. Aurora Municipal Court covers city ordinance violations within Aurora and is not in iCourt. See our guide on searching by name and city.
Court system overview
The 18th Judicial District covers Arapahoe, Douglas, Elbert, and Lincoln counties. The Arapahoe County Justice Center in Centennial houses both the District Court and the County Court. District Court handles felony criminal matters, civil cases over $25,000, domestic relations, juvenile, and probate. County Court handles misdemeanor criminal matters, traffic violations, and civil cases under $25,000. Both are accessible through iCourt with Arapahoe County selected.
Aurora Municipal Court handles ordinance violations within Aurora city limits, separate from both iCourt systems. Englewood Municipal Court, Littleton Municipal Court, and Centennial operate their own municipal courts for their respective city ordinance matters. For a complete Arapahoe County records check for an Aurora resident, iCourt covers county-level matters and Aurora Municipal Court covers city-level matters. See our court records guide.

Marriage records in Arapahoe County
Marriage licenses in Colorado are issued by the county clerk in the county where the license is obtained. Arapahoe County Clerk and Recorder issues and holds Arapahoe County marriage licenses at arapahoegov.com/clerk. Colorado Department of Public Health and Environment maintains a statewide vital records index at cdphe.colorado.gov/vital-records — certified copies require proper qualification and a fee.
Aurora's large Latino and East African communities mean that Spanish-language and East African surname variant awareness is relevant for marriage index searches. Two-surname compound forms and multiple romanization variants of the same name occur across records for the same person. For a full guide to marriage record searches see our marriage record search guide.
Divorce records in Arapahoe County
Divorce cases in Colorado are filed in District Court in the county of residence. Arapahoe County District Court Family Division handles divorce filings for Arapahoe County residents, with case indexes accessible through iCourt at iCourt.co with Arapahoe County selected. Colorado requires 91 days of state residency before filing. Full documents require the Arapahoe County District Court clerk in Centennial.
For subjects who divorced while living in Denver before moving to Aurora or Arapahoe County, those records are in Denver's separate court portal at denvercountycourt.org — not in iCourt. The aggregator address chain identifies prior Denver residency before any portal selection. For a full guide to divorce record searches see our divorce record search guide.
Industry insight
Aurora's three-county footprint is the single biggest source of misdirected searches I see in the Denver metro. Aurora has roughly 390,000 residents spread across Arapahoe, Denver, and Douglas counties, and most people searching for an Aurora resident assume it means one court system. It does not. The ZIP code is the fastest routing check — most Aurora ZIP codes (80010 through 80017) are Arapahoe County, but the northwest edge near the Denver border is Denver County. A county assessor parcel lookup for any address that produces ambiguity takes 30 seconds and prevents a wasted search in the wrong system.
The Centennial county seat is another consistent source of confusion. Many people searching Arapahoe County records expect the courthouse to be in Aurora given that Aurora is the largest city. The Arapahoe County Justice Center is in Centennial, not Aurora. Aurora has its own separate municipal court at the city level. These are entirely different systems.
Common mistakes when searching in Arapahoe County
- Not confirming the county for an Aurora address before selecting a court portal — Aurora spans Arapahoe, Denver, and Douglas counties. Using iCourt for an address that is actually in Denver County returns nothing, because Denver is not in iCourt. Confirm the county using the Arapahoe County Assessor parcel lookup before running any portal search for Aurora addresses.
- Expecting the Arapahoe County courthouse to be in Aurora — the Arapahoe County Justice Center is in Centennial (the county seat), not in Aurora. Aurora has a separate municipal court for city ordinance violations that is not in iCourt. In-person document requests route to Centennial, not Aurora.
- Not checking Aurora Municipal Court for city ordinance violations — iCourt covers Arapahoe County District Court and County Court only. Aurora Municipal Court handles ordinance violations within Aurora city limits in a system entirely separate from iCourt. Direct contact with Aurora Municipal Court is required for those records.
- Not checking prior Denver records for subjects who recently moved to Aurora — many current Aurora residents have prior Denver addresses. Denver court records are in the Denver portal at denvercountycourt.org, not in iCourt. The aggregator address chain identifies prior Denver residency before portal selection.
Major cities in Arapahoe County
Aurora
Aurora (est. pop. 390,000 in Arapahoe County portion — U.S. Census Bureau, 2023 ACS) is Colorado's third-largest city overall and the largest community in Arapahoe County. Aurora has a highly diverse population including large Latino, East African (Somali, Ethiopian, Eritrean), and Southeast Asian communities. Aurora's East African community creates specific name variant considerations — Somali three-part patronymic chains and Ethiopian patronymic-as-surname conventions mean the same person may appear under different surname configurations across different records. Aurora generates the county's highest court filing volume by a significant margin.
Centennial
Centennial (est. pop. 110,000 — U.S. Census Bureau, 2023 ACS) is the Arapahoe County seat and one of the largest incorporated cities in the United States at the time of its incorporation in 2001. Centennial has a stable, affluent suburban character with above-average homeownership rates. The Arapahoe County Justice Center is located in Centennial. Address histories here are among the more reliable in Arapahoe County given the homeowner-dominated demographics.
Englewood
Englewood (est. pop. 35,000 — U.S. Census Bureau, 2023 ACS) is directly south of Denver with a more urban character than most Arapahoe County communities. Englewood has its own municipal court for city ordinance violations separate from iCourt. Its proximity to Denver means many Englewood residents have prior Denver addresses and the prior Denver court records are in Denver's separate portal.
Littleton
Littleton (est. pop. 47,000 — U.S. Census Bureau, 2023 ACS) is the older county seat area along the South Platte River. Parts of Littleton extend into Jefferson and Douglas counties — an address labeled "Littleton, CO" may be in Arapahoe, Jefferson, or Douglas County. Confirm the county from the specific ZIP code before routing records requests. Littleton has its own municipal court for city ordinance violations.
Cherry Hills Village
Cherry Hills Village (est. pop. 6,500 — U.S. Census Bureau, 2023 ACS) is a small, affluent enclave entirely within Arapahoe County with one of the highest median household incomes of any Colorado community. Court filing volumes here are very low. Address histories are stable given the high homeownership rates and long residential tenure typical of the community.
Common search scenarios
Confirming the county for an Aurora address
ZIP code first: most 800-series Aurora ZIP codes (80010–80017) are Arapahoe County. For any ZIP that produces ambiguity, use the Arapahoe County Assessor parcel lookup at arapahoegov.com/assessor. Once Arapahoe County is confirmed, run iCourt with Arapahoe County selected for both district and county court records. See our guide on finding someone by name and city.
Checking Arapahoe County court records
iCourt at iCourt.co with Arapahoe County selected for district and county court records. Aurora Municipal Court for Aurora city ordinance violations — contact directly. Arapahoe County Assessor for property records and county confirmation. See our court record search guide.
After a move from Denver to Arapahoe County
Prior Denver records are in Denver's separate portal at denvercountycourt.org, not in iCourt. Current Arapahoe County records are in iCourt. The aggregator address chain identifies both the prior Denver address and the current Arapahoe County address before any portal work. A name and relative search surfaces the full address history including both. See our Denver County guide for the Denver portal details.

Frequently asked questions
Is Aurora in Arapahoe County or Denver County?
Most of Aurora is in Arapahoe County — the bulk of the city's residential area, including ZIP codes 80010 through 80017, is in Arapahoe County. However, Aurora's northwestern edge crosses into Denver County and its southern portions extend into Douglas County. For court record purposes, confirm which county a specific Aurora address falls in before choosing a court system. The Arapahoe County Assessor parcel lookup at arapahoegov.com/assessor confirms jurisdiction for any Aurora address.
Where is the Arapahoe County courthouse?
The Arapahoe County Justice Center, which houses both the District Court and County Court, is located in Centennial — the county seat. It is not in Aurora. Aurora has a separate municipal court for Aurora city ordinance violations, which is an entirely different system from the county courts. For in-person document requests or Arapahoe County court clerk contact, route to Centennial, not Aurora.
Where do I find marriage and divorce records for Arapahoe County?
Marriage licenses are issued by the Arapahoe County Clerk and Recorder at arapahoegov.com/clerk. Colorado DPHE maintains a statewide vital records index — certified copies require qualification and a fee. Divorce records are in Arapahoe County District Court Family Division, accessible through iCourt at iCourt.co with Arapahoe County selected. Full divorce documents require the Arapahoe County District Court clerk in Centennial.
Does iCourt cover both district court and county court for Arapahoe County?
Yes. Unlike Denver County, which requires a separate portal, Arapahoe County is fully integrated into Colorado's statewide iCourt portal at iCourt.co. Selecting Arapahoe County in iCourt provides access to both the District Court (felonies, civil over $25,000, family, probate) and the County Court (misdemeanors, traffic, civil under $25,000) in one search interface.
Are Aurora Municipal Court records in iCourt?
No. iCourt covers Arapahoe County District Court and County Court only. Aurora Municipal Court handles city ordinance violations within Aurora city limits in a completely separate system not integrated with iCourt. Direct contact with Aurora Municipal Court is required for those records. Similarly, Englewood Municipal Court, Littleton Municipal Court, and Centennial's municipal court are separate systems outside iCourt.
How do I find property records for Arapahoe County?
Arapahoe County Assessor at arapahoegov.com/assessor provides online ownership data and parcel maps searchable by owner name and address. This is particularly useful for confirming county jurisdiction for Aurora addresses before running any court portal — a parcel lookup confirms whether a specific Aurora address is in Arapahoe, Denver, or Douglas County.
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.
