The Lewis and Clark County Jail Roster in Montana is a public resource that allows anyone to check who is currently in custody. LewisandClarkCourt.us provides access to publicly available information about current and recently arrested individuals. Additionally, you can use the official website of the Lewis and Clark County Sheriff's Office, visit the jail in person, or call. A search in the roster allows you to find out the custody status of a person, the charges filed, and the booking date. The roster is maintained by the Lewis and Clark County Detention Center, it is regularly updated and posted on county resources.
Search Current Inmates in Lewis and Clark Jail
To find information about a person currently in custody at the county jail, use one of the methods below.
Online Search
- Go to LewisandClarkCourt.us to search publicly available court records related to detained individuals.
- To check court cases, use the Montana Public Access Portal — it covers district courts and courts of limited jurisdiction across the state.
- If the person has already been transferred to the state correctional system, use the Offender Search of the Montana Department of Corrections.
To start the search, you will need the full legal name of the detained person. The booking number speeds up the process but is not mandatory.
By Phone
Call the main line of the Lewis and Clark County Detention Center. The operator can confirm if a specific person is being held if you provide the full name. For emergencies, use the 911 line instead of the general jail number.
In-Person Visit
Visit the jail reception during business hours. Approach the public information window — the staff will assist with the search.
Note: Information about juvenile offenders is not included in the public inmate roster according to Montana law.
Find Lewis and Clark Jail Booking Records Online
A booking record is created at the moment a detained person is officially registered in the jail. This process includes recording personal data, photographing, and fingerprinting.
Each record contains:
- A unique booking number
- The date and time of registration
- A list of charges filed
- The name of the arresting agency (sheriff, Helena police, state patrol, etc.)
- The bail amount, if set
These records are generally public. Online access is possible through the roster on the sheriff's office website or through the Montana Judicial Branch portal, where related court cases are displayed. If you need an official copy of the booking record, submit a written request for public records to the Detention Center or the sheriff's office.
For a more in-depth check of a person's criminal history, the Montana Department of Justice offers a background check service, available to law enforcement agencies and, under certain conditions, the general public.
Search the Lewis and Clark Jail Roster by Last Name or Booking Number
The inmate roster supports two main search methods.
Search by Last Name
Enter the last name of the detained person in the appropriate field. Adding the first name will narrow the results, which is especially useful for common last names. Some practical tips:
- Check the spelling — even one mistake can lead to no results
- Try spelling variations if the last name has non-standard transliteration
- If the roster appears as a static list without a search field, use the browser's Ctrl+F function (or Cmd+F on Mac) to search the page
Search by Booking Number
The booking number is a unique identifier assigned during registration. It provides an exact result without the risk of confusion with namesakes. This number is usually provided to the detained person and their attorney.
If the Search Yields No Results
The absence of a name in the roster does not always mean the person has not been detained. Possible reasons:
- The registration process is not yet complete — there may be a few hours between the actual arrest and the appearance of the record in the system.
- The person has already been released on bail or by court decision.
- The name is recorded differently than you expect (for example, the official name is used instead of a nickname).
- The person has been transferred to another facility — for example, to the Montana Department of Corrections.
In any of these cases, it is most reliable to call the jail directly.
Jail Roster Updates and Search Limitations in Lewis and Clark
The Detention Center inmate roster is updated throughout the workday, but it does not happen instantly. There is usually a delay of one to several hours between the time of arrest and the appearance of the record in the online roster — the time needed to complete the booking procedure.
Main limitations to consider:
| Limitation | Explanation |
|---|---|
| Delay after arrest | The record appears only after full registration is completed, which can take 1–4 hours |
| Removal after release | Records of released individuals may disappear from the roster shortly after their release |
| Current inmates only | The roster shows those currently in custody — it is not an archive of all past bookings |
| Technical delays | Website updates may lag behind the internal jail database |
If you need information about past bookings, submit a public records request to the county sheriff's office. To search documents registered in Lewis and Clark County, including court orders and other official papers, use the Clerk and Recorder portal.
The roster does not contain information about individuals detained by federal agencies or those held in facilities of other counties. For a search across the entire state correctional system, refer to the Offender Search on the Montana.gov website.
