Michigan does not have a single agency officially called a Department of Justice the way the federal government does. Legal and law enforcement duties here are split among the Michigan Department of Attorney General, the Michigan State Police, 83 county prosecutors, and federal offices such as the U.S. Attorneys. Our directory lists four offices filed under the Department of Justice name in Michigan: two in Port Huron, one in Detroit, and one in Flint. This page explains what those offices may handle, who runs the services behind them, and how to reach the right one before you drive anywhere.
How Justice Services Are Organized Across Michigan
The Michigan Constitution of 1963 makes the Attorney General an elected statewide official. The office is based in Lansing and acts as the state's chief legal officer. It defends state agencies in court, issues formal legal opinions, and enforces consumer protection and charitable trust laws. Dana Nessel has held the post since January 2019.
Criminal prosecution works differently. Each of Michigan's 83 counties elects a prosecuting attorney to a four-year term. That prosecutor decides whether to charge most felonies and misdemeanors committed in the county. The Attorney General takes on a narrower set of cases, such as public corruption, health care fraud, environmental crimes, and matters a county prosecutor refers upward.
Statewide policing sits with the Michigan State Police. Its duties include the Michigan Sex Offender Registry, the state crime laboratories, and the central repository of criminal history records. Sheriffs, city police departments, and tribal police handle day-to-day patrol and investigations at the local level.
Because the work is divided this way, your first step is deciding what kind of problem you have. The list below matches common needs to the body that normally handles them in Michigan.
- Complaint about a business: the Attorney General's Consumer Protection Team in Lansing, which accepts complaints online or by mail.
- Criminal charge or victim questions: the county prosecuting attorney's office and its victim advocates.
- Criminal history record: the Michigan State Police, through its online ICHAT system or fingerprint-based checks.
- Discrimination at work, in housing, or in public services: the Michigan Department of Civil Rights.
- Federal crime or federal agency matter: the U.S. Attorney's Office for the Eastern or Western District of Michigan.
- Public records: the specific agency holding the record, under the Michigan Freedom of Information Act.
Federal Justice Offices in Michigan's Two Districts
Michigan is divided into two federal judicial districts. The Eastern District covers southeast Michigan and the eastern Lower Peninsula, including Wayne, Genesee, and St. Clair counties. Its U.S. Attorney's Office is in Detroit, and federal court also sits in several other eastern cities, including Flint.
The Western District covers the western Lower Peninsula and the entire Upper Peninsula. Its U.S. Attorney's Office is in Grand Rapids, with a Marquette office that serves the U.P. Federal prosecutors handle matters like drug trafficking networks, large-scale fraud, firearms offenses, and crimes on federal property. They do not handle ordinary traffic tickets, landlord disputes, or most local criminal cases.
The FBI's Detroit Field Office covers major federal investigations across the state, with smaller resident agencies in other cities. If you have a tip about a federal crime, contacting those channels directly is usually faster than visiting a county office.
Detroit, Flint and Port Huron: The Offices in Our Michigan Listings
Our records list the Detroit Michigan Department of Justice at 477 Michigan Avenue, phone 313-965-2902, in Wayne County. Wayne County is the state's most populous county. Downtown Detroit holds the Eastern District's federal courthouse, the county's criminal courts, and a large share of the region's law firms. For federal questions, the Detroit area is the center of activity.
In Genesee County, the Flint Michigan Department of Justice is listed at 420 Saginaw Street, phone 810-341-7557. Flint is the county seat and drew national attention during the water crisis, which led to state criminal investigations, civil lawsuits, and a settlement worth hundreds of millions of dollars. Many Flint residents therefore already know the Attorney General's office as an active presence in local affairs.
In St. Clair County, the Port Huron Michigan Department of Justice is listed at 1410 Elmwood Street, phone 810-982-0133. Port Huron is the county seat and sits at the Blue Water Bridge crossing to Sarnia, Ontario. Border enforcement and customs matters add a federal layer to local justice work. Our database holds a second Port Huron entry, so compare the listing details before you call or drive over.
A practical caution: directory names do not always match an agency's legal name. Since Michigan has no state agency titled Department of Justice, call ahead and ask three things. Which agency operates at the address? Does it serve the public in person? What appointment or documents does it require?
Metro Detroit Versus Rural Michigan: What Changes for Residents
Southeast Michigan has the densest concentration of legal offices. Wayne, Oakland, and Macomb counties run large prosecutor offices with specialized units, dedicated victim services staff, and several court locations. You may find walk-in help there. Parking, security screening, and wait times can still eat up an hour, so arrive early.
Outside metro Detroit, offices are smaller. In the northern Lower Peninsula and the Upper Peninsula, a prosecutor's office may have only a few attorneys, and the nearest federal office can be hours away by car. Phone and email contact are often faster than visiting. Some matters, such as consumer complaints, can be started online through state agencies.
Mid-sized areas fall between those extremes. In Genesee and St. Clair counties, the county seat has a prosecutor's office, a circuit court, and district courts. Federal services usually mean a trip to Detroit or a call to the U.S. Attorney's office there. For county-level listings, see our pages for St. Clair County, Wayne County, and Genesee County.
What to Bring and When to Go in Michigan
Preparation saves more time than any other step. Gather these items before you leave home:
- A government-issued photo ID, such as a Michigan driver's license or state ID.
- Your case number, citation number, or docket number, if one exists.
- Copies of contracts, letters, emails, receipts, or police reports. Keep the originals.
- A short written timeline with names, dates, and amounts.
- A list of your questions, ranked by importance.
Most government offices in Michigan keep weekday daytime hours and close on state and federal holidays. Courthouses often have security lines in the morning, and Mondays tend to be busy. Call the day before to confirm hours, since hours can change with court schedules.
If you need records instead of an appointment, the Michigan Freedom of Information Act lets you request public records in writing. A public body generally must respond within five business days. It can extend that deadline once by up to ten business days.
Staff at prosecutor and Attorney General offices represent the public or the state, not you personally. For legal advice about your own case, contact a private attorney, the State Bar of Michigan lawyer referral service, or a local legal aid organization. Michigan Legal Help also publishes plain-language guides for people handling cases without a lawyer.
Department of Justice resources in Michigan include U.S. Attorney's Office district operations, FBI field offices, and the Michigan Attorney General's Office, which enforces state law and consumer protection statutes at the state level while coordinating with federal DOJ components on major investigations.
Department Of Justice locations are available in 3 cities across Michigan. They are spread across 3 counties.
Cities with the highest concentration include Port Huron, Detroit, Flint, reflecting federal district headquarters and major cities where DOJ field offices, U.S. Attorneys, and federal law enforcement units are based.
Residents of Michigan who need to engage with the DOJ should identify the correct agency division for their matter — whether it involves civil rights, a federal crime, antitrust, or a FOIA request — before contacting the appropriate office.

Using Justice Offices in St. Clair, Wayne and Genesee Counties
Three counties anchor the listings on this page. In St. Clair County, Port Huron is the county seat, so prosecutor, circuit court, and sheriff matters are handled there. In Wayne County, Detroit hosts the largest concentration of criminal courts and federal offices in Michigan. In Genesee County, Flint is the center for county government and legal services.
Before you go, write down the case number, the name of any officer or attorney involved, and the dates of key events. Offices answer faster when you can state your question in a sentence or two. If the person who answers says the matter belongs to another agency, ask for that agency's name and a direct phone number instead of a general line.
Scams deserve a mention. Government offices in Michigan do not demand payment by gift card, cryptocurrency, or wire transfer to avoid arrest. If a caller claiming to be from a justice agency asks for that, hang up and report it to the Attorney General's consumer protection team or your local police.
Finally, check the date on any information you find online. Phone numbers, office locations, and hours change, and a directory listing is only a starting point. A short call confirms what a website cannot.
