Wisconsin handles state-level legal and law enforcement work through one agency: the Wisconsin Department of Justice, led by the state Attorney General. The department is headquartered in Madison and operates mainly under Chapter 165 of the Wisconsin Statutes. It is not a county courthouse or a local police station, and that difference trips up many people. Our directory lists six offices across Madison, Milwaukee and Oxford, in Dane, Milwaukee and Marquette counties. This page explains what those offices do, what they do not do, and how to get your question to the right place the first time.
How the Wisconsin Department of Justice Is Organized
The Attorney General is elected statewide to a four-year term. The Wisconsin Constitution creates the office, and Chapter 165 of the statutes sets out most of the department's duties. The Attorney General serves as the state's chief legal officer. In practice, that means the department represents the State of Wisconsin in court, defends state agencies when they are sued, and handles criminal appeals brought by the state.
Several divisions carry out the work. The Division of Criminal Investigation (DCI) assists local agencies with complex cases and runs specialized units, including the state's Internet Crimes Against Children task force. The Division of Law Enforcement Services maintains criminal history records, supports the firearms background check system, and works on training standards for Wisconsin officers. The Division of Forensic Sciences operates the state crime laboratories in Madison, Milwaukee and Wausau. The Division of Legal Services handles litigation and legal opinions. The Office of Crime Victim Services runs victim compensation and support programs.
Local prosecution works differently. Each county has an elected district attorney who prosecutes most crimes there. Sheriffs are elected by county, and city police departments answer to their municipalities. The state Department of Justice does not replace any of them. It supports them with laboratories, records, training and investigators, and it steps in directly when a case needs state-level resources or when a local conflict of interest requires it.
The Attorney General also issues formal legal opinions, but these go to certain public officials, such as district attorneys and legislators. Private individuals cannot request one.
Department of Justice Offices in Madison, Milwaukee and Oxford
Madison is the center of the system. Our database lists three offices there, including the Madison Wisconsin Department of Justice at 345 West Washington Avenue (608-264-5111). The state capital is also the seat of Dane County, so state government, the legislature and the Wisconsin Supreme Court are all within a short distance of one another. If you need to reach department leadership, ask about a program run from headquarters, or follow up on a statewide matter, Madison is usually the right starting point. Because there are several Madison listings, check the address on each before you visit.
Milwaukee has two listings, including the Milwaukee Wisconsin Department of Justice at 1578 South 11th Street (414-382-7500). Milwaukee is the state's largest city and the center of Milwaukee County, which produces a large share of the state's criminal casework. A southeastern Wisconsin presence puts investigators and forensic staff closer to those cases and to the police departments that submit evidence. Call ahead to confirm which services are handled at a specific address before you drive there.
The Oxford Wisconsin Department of Justice, at 350 Elk Avenue (608-584-5511), sits in Marquette County in central Wisconsin. It is a small-town listing in a lightly populated county, which is a useful reminder that state justice services are not limited to Madison and Milwaukee. Phone first, since smaller offices can have limited public hours.
Metro and Rural Differences Across Wisconsin
In Dane and Milwaukee counties, residents have many options close by. Both are home to large police departments, busy district attorney offices and a dense network of courts. State resources reach these areas through laboratory submissions, joint investigations and training programs, so many residents never notice the state's role until a serious case arises. Walk-in visits are realistic, and staff handle a high volume of questions.
Rural Wisconsin works differently. A county such as Marquette has a small sheriff's office, a modest courthouse in Montello, and fewer full-time law enforcement staff. Departments in smaller communities lean on state help for forensic testing, specialized investigations and officer training. Distance matters too. Someone in a northern county may drive hours to reach Madison or Milwaukee, which is one reason the state's crime laboratories include a site in Wausau, and why phone and online services matter so much outside the cities.
If you live outside the metro areas, start with a call or the department's website before planning a trip. Many tasks, including concealed carry applications and record checks, are designed to be completed online or by mail. Save in-person visits for situations where staff specifically ask for them.
What Wisconsin Residents Typically Ask the Department of Justice For
The department's public-facing work covers a handful of recurring needs. These are the ones people raise most often:
- Concealed carry licenses: the department issues and renews Wisconsin licenses, which last five years.
- Firearm purchase background checks: licensed dealers submit these to the state, so buyers generally do not call the department themselves.
- Criminal history record checks: employers, landlords, volunteer groups and individuals can request Wisconsin records.
- Crime victim compensation: the Office of Crime Victim Services helps people with certain costs after a violent crime.
- Open government questions: the department's Office of Open Government answers questions about the Open Records and Open Meetings laws.
- Medication disposal and prevention programs: Operation Medicine Cabinet supports drug take-back efforts around the state.
For a dispute with a business or landlord, the Wisconsin Department of Agriculture, Trade and Consumer Protection is usually the better first stop. For a crime in progress, call 911 rather than any state office.
Preparing for a Wisconsin Department of Justice Visit
Most state offices keep weekday business hours, and mornings tend to be quieter. Bring a government-issued photo ID, any case or reference number, and copies of relevant documents. If you are asking about a specific program, write down your questions beforehand. Staff can explain procedures, but they cannot give legal advice about your personal situation. If your issue involves a pending court case, your attorney or the county district attorney is the right contact.
If you want public records, Wisconsin's Public Records Law lets you make a request in person, by phone or in writing. A written request leaves a clear trail, and you should describe the records as specifically as you can, including dates, names and subject matter. Specific requests are usually answered faster than broad ones.
Use the county pages to compare nearby listings: Dane County for the Madison offices, Milwaukee County for the state's largest city, and Marquette County for Oxford and the surrounding area.
Department of Justice resources in Wisconsin include U.S. Attorney's Office district operations, FBI field offices, and the Wisconsin 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.

Using Department of Justice Services Across Wisconsin
Wisconsin's justice system has layers, and most residents deal with the local layer first. Your city police department or county sheriff takes reports, and your county district attorney decides whether to file charges. The Wisconsin Department of Justice becomes involved when a case needs state laboratories, statewide records, a special investigation or an appeal.
Geography shapes the experience. In Dane County, the Madison listings put you close to state government, so records questions and program inquiries are easy to bring in person. In Milwaukee County, the South 11th Street listing serves the state's most populous area. In Marquette County, the Oxford listing is a reminder that a rural resident may rely more on the phone and the mail than on a counter visit.
Before you travel, gather three things: a government-issued photo ID, any case or reference number, and copies of relevant paperwork. Ask whether an appointment is needed. Write down the name of the person you speak with and the date, which helps if you must follow up later. Keep in mind that state offices cannot give private legal advice, so a question about your own rights may need a licensed attorney.
