Search St. Croix County Criminal History
St. Croix County Criminal History searches go better when you match the office to the record first. The clerk keeps the circuit court file. The sheriff keeps arrest, jail, and incident material. The register of deeds keeps property and vital records that can help confirm the right person or address. St. Croix County also has municipal courts in Baldwin, Deer Park, Glenwood City, Hammond, Hudson, New Richmond, North Hudson, Roberts, Somerset, Spring Valley, Star Prairie, and Woodville. That local layer matters because a city or village court can hold the first version of a case before the county file begins.
St. Croix County Overview
St. Croix County Criminal History Records
The county court file lives with the St. Croix County Clerk of Circuit Court at the St. Croix County Government Center, 1101 Carmichael Road, Hudson, WI 54016. The phone number is (715) 386-4645, and the office lists weekday hours from 8:00 AM to 4:30 PM. Public access terminals, WCCA online case search, and a $5 research fee when the case number is not known point you toward the clerk when a St. Croix County Criminal History search needs the actual file instead of a simple name result.
The St. Croix County Sheriff's Office is at 1752 Dorset Lane in New Richmond. The phone number is (715) 386-4691, and Sheriff Scott Knudson oversees the office. Online inmate search, arrest records, and incident reports are part of the sheriff side of the search. That makes the sheriff a smart first stop when the first clue is custody, a booking, or a report number rather than a court filing.
The St. Croix County Register of Deeds keeps vital and property records at the government center in Hudson. The office handles birth, death, and marriage certificates along with land and property records. The first copy fee is $20 and each additional copy is $3. Those records do not replace a criminal file, but they can help confirm the right person before you send the request.
St. Croix County's municipal court layer is wide. Hudson, New Richmond, Somerset, and the smaller village courts can all hold the first version of a case before the circuit file begins. That matters because a traffic or ordinance matter may stay local for a while and still shape the county search. If you know the city and the date, you can save time. If you skip the local desk, you can miss the first record trail altogether.
St. Croix County Criminal History Source Pages
The Wisconsin State Law Library county directory at wilawlibrary.gov/topics/county.php gives St. Croix County an official fallback when you need a state reference point for the courthouse path.

That directory keeps the search tied to a real public office path instead of a broad web result.
The Wisconsin DOJ Crime Information Bureau page at DOJ CIB explains the statewide name-check system behind Wisconsin criminal history searches.

That state page is useful when the county file needs a broader Wisconsin match.
The Wisconsin Court System docket portal at WCCA and WSCCA keeps the circuit and appellate side of the search in the official court system.

It helps you move from a county clue to the court record without leaving the state system.
St. Croix County Criminal History at the Clerk
The clerk office is the cleanest route when you need the paper file. The office is at the St. Croix County Government Center, 1101 Carmichael Road, Hudson, WI 54016. The phone number is (715) 386-4645, and the fax number is (715) 386-4647. The office hours are Monday through Friday, 8:00 a.m. to 4:30 p.m. That is useful when you need to call before you travel or before you mail a request.
The clerk page says public access terminals are available and WCCA online case search is open. Copy fees are $1.25 per page and $5.00 certified. A $5 research fee applies when you do not have a case number. Those details matter because they tell you how much help the office may need to find the file and how much copying your request may require.
The office is also where a docket becomes a real file request. If you already know the case number, WCCA can help you check the docket before you ask for the copy. If you do not, the clerk can still help, but a narrow name and date range will move the search faster. That is especially useful in a county with a busy river corridor and several active local courts.
St. Croix County Criminal History and Sheriff Records
The sheriff office is the better first stop when the search starts with an arrest, a jail event, or an incident report. The St. Croix County Sheriff's Office is at 1752 Dorset Lane in New Richmond, and the public phone number is (715) 386-4691. That level of detail matters because sheriff records often hold the first official note in a St. Croix County Criminal History search.
The sheriff page says online inmate search is available, and arrest records and incident reports can be requested through the office. Those details can show the first report, the custody step, or the place where the event started. They can also help when a person has a common name and you need the local clue first.
The sheriff office can also help you decide whether the event stayed in St. Croix County or moved elsewhere. That is especially useful when the search begins with a Hudson or New Richmond clue but the report line is thin. A short, specific request usually gets a better answer than a broad one.
St. Croix County Criminal History Search Tools
State tools fill the gap when the county office is not enough. The public DOJ portal at WORCS is the Wisconsin name based criminal history check. The Wisconsin Court System forms page at Wisconsin Circuit Court Forms is useful when you need court paperwork tied to a local case. If the person is under supervision, the DOC offender page at DOC offender search is the separate state lookup.
The legal frame comes from Chapter 19 and Wis. Stat. 165.82. Chapter 19 explains public records access. Section 165.82 explains the Crime Information Bureau role. Those rules matter when a record is open, sealed, or not visible on the public side of the system. A missing hit does not always mean the file is gone.
When those state tools are used with the clerk, sheriff, and register of deeds, St. Croix County Criminal History research becomes more complete and easier to manage.
What Helps a St. Croix Search
Good search details save time and help staff find the right file.
- Full name and any spelling variant
- Approximate date or year of the event
- Case number, if you already have it
- Whether you need a docket, copy, or certified record
- Any office name already tied to the record
If you are not sure where the record sits, start with the sheriff if you need arrest or jail material, then use the clerk if you need the court file. If you need a broader Wisconsin view, use WORCS or WCCA. That order keeps the work in the right lane and avoids a wrong office request.
Hours matter too. The clerk, sheriff, and register of deeds all follow weekday office hours. If you are mailing a request, include a return envelope and the exact name you want checked so the office can move it without back and forth. In St. Croix County, that simple prep can save a second trip and a second wait. Note: A date and the right office usually matter more than a broad name search.
