Michigan has 83 counties and two physically separate peninsulas — the Lower Peninsula, which holds about 97 percent of the population, and the Upper Peninsula, accessible from the Lower Peninsula only via the Mackinac Bridge. The Upper Peninsula's smaller, more rural counties have lower record digitization rates than the urban southeast, which can produce dead ends in online searches that a downstate county would resolve immediately. Understanding which peninsula and which region you're searching in is the first practical step in any Michigan records search.
If you are comparing more than one state, you can also review our people search by state guides to understand how records differ across jurisdictions.
Key takeaways
- Michigan's ICHAT (Internet Criminal History Access Tool) provides a fee-based statewide name search for public conviction records — it is the correct starting point for Michigan criminal history, not county-by-county searching.
- OTIS (Offender Tracking Information System) is a free complement to ICHAT covering anyone currently in prison, on parole, or on probation — it includes photos and physical descriptions, making it the better tool for identity confirmation when a common name produces multiple ICHAT results.
- Michigan's Upper Peninsula has lower record digitization than the Lower Peninsula — online searches that work immediately in Wayne or Kent County may require in-person or mail requests in UP counties.
- Wayne County contains Detroit plus 42 other incorporated cities — a "Detroit" address may actually place records in Dearborn, Livonia, or Westland, all of which are in Wayne County but have their own municipal courts.
How searches work in Michigan
Searching for someone in Michigan typically starts with ICHAT for statewide criminal history context, then moves to the county circuit or district court portal for civil and local criminal matters. Michigan has a three-tier trial court system — circuit courts, district courts, and probate courts — organized by county, so knowing the county is essential before any court-level search.
For current offenders or people with recent contact with the corrections system, OTIS provides free access including physical descriptions and photos that make identity confirmation much more reliable than a name-only ICHAT result. If you already know the city, our find someone by name and city guide can help narrow the search more quickly.
Industry insight
The ICHAT versus OTIS distinction is one of the most underused pieces of search strategy for Michigan. ICHAT covers public conviction records — cases that resulted in a conviction and are not sealed. It costs a small fee and requires a name search. OTIS is free and covers anyone currently under state correctional supervision — prison, parole, or probation. If I'm trying to confirm identity for someone with a common name and I suspect recent correctional history, I go to OTIS first because the photos and physical descriptions resolve the identity question immediately, before I've spent any money on ICHAT.
The Upper Peninsula digitization gap is something that catches researchers who work primarily in the southeast. Wayne, Oakland, Macomb, and Kent counties all have well-maintained online portals. Keweenaw, Ontonagon, and Schoolcraft counties — small UP counties with under 10,000 residents each — may require phone or mail requests for the same information. If the person spent time in the UP, budget extra time for the records request.
Common mistakes when searching by name in Michigan
- Starting with county-by-county court searches before running ICHAT — Michigan's statewide criminal history tool covers all 83 counties in one search and should be the first stop for criminal history context.
- Missing OTIS entirely when the subject may be under current correctional supervision — it's free, includes photos, and is far faster for identity confirmation than ICHAT for current offenders.
- Treating a "Detroit" address as meaning Wayne County Circuit Court when the person may have records in one of 42 other Wayne County cities, each with its own district court.
- Applying Lower Peninsula digital access expectations to Upper Peninsula counties where online records may be limited or unavailable.

Michigan's trial courts are organized by county across three tiers. Circuit courts handle felonies, major civil cases, family law, and equity. District courts handle misdemeanors, civil cases under $25,000, landlord-tenant matters, and traffic violations. Probate courts handle estates and mental health matters. All three are county-specific. Michigan's statewide case management system (MiCourt) provides online access for many counties, but coverage varies — some smaller counties, particularly in the Upper Peninsula, may require direct contact with the county clerk.

Crime statistics in Michigan are published by the Michigan State Police through its Michigan Incident Crime Reporting program. The 2024 violent crime rate of 434 per 100,000 placed Michigan 20.9 percent above the national average, driven significantly by Detroit's high per-capita rate. Outside Detroit and a handful of other urban centers, much of Michigan reports rates well below the statewide figure. When running a criminal record search, county-level context is essential.
Public records law
Michigan's public records framework is the Freedom of Information Act (FOIA), codified at MCL 15.231 et seq. The Act requires public bodies to respond to requests within five business days and allows up to ten additional business days with written notice. Michigan FOIA applies to state and local government bodies; the legislature and courts are not subject to FOIA and operate under their own access rules.
Key exemptions include: personnel records to the extent disclosure would constitute a clearly unwarranted invasion of privacy (MCL 15.243(1)(a)); law enforcement records compiled for law enforcement purposes whose disclosure would interfere with enforcement proceedings (MCL 15.243(1)(b)); and records specifically exempt by statute. Court records are accessible through the county clerk system and MiCourt rather than through FOIA requests.
ICHAT and OTIS — Michigan's two criminal history tools
Michigan provides two distinct tools for criminal history searches. ICHAT (Internet Criminal History Access Tool), managed by the Michigan State Police, is a name-based statewide search for public criminal conviction records — it costs a small per-search fee and covers all 83 counties in one query. OTIS (Offender Tracking Information System), managed by the Michigan Department of Corrections, is free and covers anyone currently in state prison, on parole, or on probation — it includes photographs and physical descriptions. ICHAT covers the broader universe of past convictions; OTIS is more specific to current state supervision. The two together provide a more complete picture than either alone.
Official public record sources in Michigan
| Agency | Records maintained | Notes |
|---|---|---|
| Michigan Courts (courts.michigan.gov / MiCourt) | Circuit and district court case information for most counties | Coverage varies by county. Well-maintained for southeast Michigan; more limited for Upper Peninsula counties. |
| Michigan State Police — ICHAT | Statewide public criminal conviction records | Fee-based name search. Covers all 83 counties. Does not include non-public or sealed records. |
| Michigan Department of Corrections — OTIS | Current offenders in prison, on parole, or on probation | Free. Includes photos and physical descriptions. Best tool for identity confirmation when common names return multiple ICHAT results. |
| County clerk / register of deeds offices | Property records, deeds, liens, vital records | Maintained county-by-county. Wayne, Oakland, Macomb, and Kent County recorders provide strong online portals; UP counties may require mail or in-person requests. |

Michigan marriage records
Michigan marriage licenses are issued and recorded by the county clerk in the county where the license was obtained. The Michigan Department of Health and Human Services (MDHHS) maintains a statewide marriage index from 1867 to the present, available by mail or through authorized vendors; there is no public online name search. For most research purposes, the individual county clerk is the faster path. Wayne County, Oakland County, Macomb County, and Kent County all have varying degrees of online clerk access. Most Michigan county clerks maintain their own portals at the county level.
Michigan does not restrict informational copies of marriage records to named parties. For a full guide to how marriage record searches work across all states, see the marriage record search guide.
Michigan divorce records
Divorce cases in Michigan are filed in Circuit Court (Family Division) in the county where one party resided. Michigan requires at least 10 days of residency in the county before filing. Case indexes are accessible through MiCourt for most Lower Peninsula counties. The MDHHS maintains a statewide divorce index from 1897 to the present — requests go by mail; no public online name search is available. This makes MiCourt the more practical starting point for divorce record index searches.
Wayne County generates Michigan's highest divorce filing volume by far, followed by Oakland and Macomb counties. For Upper Peninsula counties, MiCourt coverage is more limited and direct contact with the county circuit court clerk may be necessary. For a full guide to how divorce record searches work across all states, see the divorce record search guide.
Population context
Michigan's population is concentrated in the Lower Peninsula, particularly in the southeast. The Detroit metropolitan area — Wayne, Oakland, and Macomb counties at its core, with Washtenaw, Livingston, and St. Clair counties in the broader MSA — holds roughly 4.3 million people. The Grand Rapids area (Kent and Ottawa counties) is the second-largest metro with about 1.4 million. These two regions account for the majority of the state's records activity and most name-search noise.
The Upper Peninsula is geographically the size of Massachusetts, Connecticut, and Rhode Island combined, but holds fewer than 300,000 people. Its 15 counties are accessible from the Lower Peninsula only via the Mackinac Bridge. Search behavior differs meaningfully between the two peninsulas: Lower Peninsula urban counties have robust digital infrastructure; UP counties often have paper-only access for older records. A name and relative search that identifies a UP county early in the process can save significant time.
Example search scenarios in Michigan
Searching by name and city
If you know the person's name and a likely city, confirm the county first: Detroit is in Wayne County, Grand Rapids is in Kent County, Ann Arbor is in Washtenaw County, Lansing is in Ingham County. Then run ICHAT for statewide criminal history, and check the MiCourt portal for the relevant county for civil and local criminal case access. For Wayne County, note that records for Dearborn, Livonia, and Westland are in the Wayne County system but may be filed under district court rather than circuit court.
Checking county court records
Once the county is confirmed, Michigan's MiCourt system provides access for most Lower Peninsula counties. Circuit courts handle felonies and major civil cases; district courts handle misdemeanors and civil cases under $25,000 — check both if the nature of the matter is uncertain. For Upper Peninsula counties, direct county clerk contact may be necessary. See our court record search guide for more on navigating multi-tier systems.
Searching when the city is unknown
ICHAT is the fastest starting point for an unknown-city Michigan search — it covers all 83 counties and surfaces the county where the conviction occurred. From there, OTIS can confirm current status and physical identity. For civil or property matters, county register of deeds portals require knowing the county first, making ICHAT results the most efficient way to establish geographic context before any property search.
Major cities in Michigan
Detroit
Detroit (est. pop. 645,705 — U.S. Census Bureau, 2024 PEP) is the county seat of Wayne County and the state's largest city. Wayne County contains Detroit plus 42 other incorporated cities, townships, and villages — Dearborn, Livonia, Westland, and Southgate among them — each with its own district court. A "Detroit" address may actually mean records are in a neighboring city's district court rather than Detroit's own 36th District Court. Circuit court matters for all of Wayne County go through the Third Judicial Circuit in Detroit.
Grand Rapids
Grand Rapids (est. pop. 200,117 — U.S. Census Bureau, 2024 PEP) is the county seat of Kent County and the largest city in the Grand Rapids metro, which also spans Ottawa County to the west. Kent County sits in the 17th Judicial Circuit. Grand Rapids has seen consistent population growth driven by healthcare, manufacturing, and a growing technology sector. The city's growth and diversifying demographics mean name searches here benefit from relative or date-of-birth anchors more than they did a decade ago.
Warren
Warren (est. pop. 137,686 — U.S. Census Bureau, 2024 PEP) is the largest city in Macomb County and the third-largest city in Michigan. It sits in the 16th Judicial Circuit. Warren's identity as a blue-collar automotive city means long-term residents often have stable, multi-decade address histories — searches for people with deep Warren roots tend to be more straightforward than in high-mobility cities.
Ann Arbor
Ann Arbor (est. pop. 122,925 — U.S. Census Bureau, 2024 PEP) is the county seat of Washtenaw County and home to the University of Michigan, which enrolls about 48,000 students. The large student and academic population creates significant address-history turnover — people who spent time in Ann Arbor for school may have left no permanent record ties to the city beyond enrollment years. Washtenaw County's court and property records are accessible through MiCourt and the county's online portals.
Lansing
Lansing (est. pop. 115,056 — U.S. Census Bureau, 2024 ACS) is the state capital and county seat of Ingham County, sitting in the 30th Judicial Circuit. As a government employment hub, a significant portion of Lansing residents are state employees whose employment records and professional backgrounds are publicly accessible — useful as cross-reference data when identity is ambiguous. East Lansing, home to Michigan State University, is also in Ingham County and uses the same court system.
County systems in Michigan
Wayne County
Wayne County (est. pop. 1,780,000 — U.S. Census Bureau, 2024 ACS) is the most populous county in Michigan and contains Detroit plus 42 other municipalities. It sits in the 3rd Judicial Circuit for circuit court matters and has multiple district courts serving different geographic areas within the county. Wayne's large size and urban complexity mean that confirming both the city and the court tier (circuit vs. district) is essential before searching.
Oakland County
Oakland County (est. pop. 1,268,000 — U.S. Census Bureau, 2024 ACS) is the second-most populous county in Michigan and contains Pontiac as its county seat. It sits in the 6th Judicial Circuit. Oakland County is generally considered the most affluent large county in the state and contains many of Detroit's northern suburbs — Troy, Rochester Hills, Southfield, and Bloomfield Township. Oakland's court and property records systems are well-maintained and provide good online access.
Macomb County
Macomb County (est. pop. 886,000 — U.S. Census Bureau, 2024 ACS) is the third-most populous county in Michigan and contains Mount Clemens as its county seat. It sits in the 16th Judicial Circuit and contains Warren, Sterling Heights, and Clinton Township. Macomb County's demographic stability means that long-term residents often have consistent, county-contained address histories that make searches more straightforward than in higher-mobility counties.
Kent County
Kent County (est. pop. 668,000 — U.S. Census Bureau, 2024 ACS) contains Grand Rapids and sits in the 17th Judicial Circuit. Kent has been one of the fastest-growing counties in Michigan over the past decade. Kent County's court and property records are well-digitized and accessible through MiCourt and the county's own online portals.
Washtenaw County
Washtenaw County (est. pop. 375,000 — U.S. Census Bureau, 2024 ACS) contains Ann Arbor and sits in the 22nd Judicial Circuit. The University of Michigan's presence makes Washtenaw County unusual in that a significant share of its population is transient on four-year cycles. Washtenaw's digitization is strong — the county's court and property portals are among the more complete in the state.

Frequently asked questions
What is the difference between ICHAT and OTIS in Michigan?
ICHAT (Internet Criminal History Access Tool) is a fee-based statewide name search for public criminal conviction records — it covers all 83 counties and shows convictions that are not sealed. OTIS (Offender Tracking Information System) is free and covers only people currently under state correctional supervision — prison, parole, or probation — but includes photographs and physical descriptions that make it the better tool for identity confirmation when a common name returns multiple results. Use ICHAT for broader historical criminal history; use OTIS when you suspect current correctional supervision and need visual confirmation of identity.
Can you look up marriage or divorce records online in Michigan?
Partially. Marriage licenses are recorded by county clerks — many Michigan county clerk offices have varying degrees of online index access, but there is no statewide public online search. Divorce cases are in the Circuit Court Family Division, and case indexes are accessible through MiCourt for most Lower Peninsula counties. The Michigan Department of Health and Human Services maintains statewide marriage and divorce indexes from the 1860s (marriages) and 1897 (divorces) onward, available by mail. For Upper Peninsula counties, direct county clerk contact may be necessary for both.
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.
